 # Changelog
 ## [0.9.12] – 2026-05-20
 ### Fixes
 - **Pause-Status** wird jetzt korrekt erkannt: Die Bridge las den Geräte-State
  statt des verschachtelten Druckauftrags-States, dadurch wurde ein pausierter
  Druck teils noch als „druckend" angezeigt. Layer/Fortschritt/Restzeit kommen
  jetzt ebenfalls aus dem Auftrags-Report.
 ### Intern
 - Frontend (HTML/CSS/JS) aus der Python-Datei nach `web/index.html` ausgelagert,
  zur Build-Zeit wieder eingebettet — besser wartbar, für Nutzer keine Änderung.
 ### Doku
 - Community-**Home-Assistant-Integration** von @gangoke verlinkt.
 ## [0.9.11] – 2026-05-20
 ### Neu
 - **ACE Pro 2 Support (experimentell, Community-Beitrag von @gangoke, PR #26):** Die Bridge erkennt jetzt die Filament-Hardware automatisch und passt sich an:
  - **Modi:** `toolhead` (kein ACE, Standard-4-Slot-Box), `ace_direct` (ein ACE Pro 2 direkt am Toolhead), `ace_hub` (bis zu 4 ACE-Units am Slot-4-Hub) — insgesamt bis zu **19 Slots**.
  - **AMS Auto-Refill** Umschalter.
  - **Trockner:** Temperatur-/Luftfeuchte-Monitor, Start/Stop/Temp/Dauer-Steuerung, mit Material-Presets in einer neuen Config-Sektion `[ace_dry_presets]` (PLA, PLA+, PETG, TPU, ABS/ASA, PA/PC + 3 Custom).
  - **UI:** Filament-Sektion skaliert auf 19 Slots, Modus-Label, geladener Slot grün umrandet mit Lade-/Entlade-Puls-Animation, Unload/Load direkt aus dem Slot-Edit-Dialog.
  - **GCode-Farb-Mapping:** ACE2-fähig, Farbe-aus-GCode-Fix, Hinweis bei Inkonsistenz zwischen Mapping und Objekten, besseres Default-Mapping.
 > **⚠️ Experimentell:** Die ACE-Pro-2-Hardware-Pfade wurden vom Contributor mit einer einzelnen ACE2-Unit entwickelt und getestet; die 2–4-Unit-Hub-Konfigurationen sind theoretisch und auf echter Hardware ungetestet. Wir haben hier ebenfalls keine ACE2-Hardware zur Verifikation. Der Standard-`toolhead`-Pfad (ohne ACE) wurde live gegen einen echten Kobra X getestet. Wer ein Multi-ACE-Setup betreibt: bitte per Issue Rückmeldung geben.
 ### Fixes
 - **Happy-Hare-MMU-Emulation:** Es werden nur belegte Slots gesynct — kein Placeholder für leere Slots (kompatibel mit OrcaSlicer PR #13372).
 - **GCode-Farb-Dialog** zeigt nach einem neuen Upload nicht mehr die Daten der vorherigen Datei.

 ## [0.9.10] – 2026-05-17
 > **Hinweis:** Mit diesem Release wird der Fokus von neuen Features auf
 > **Stabilisierung und Bugfixing** verlagert. Die Kern-Workflows
 > (Multi-Printer, Drucker hinzufügen/entfernen, Filament-Dialog,
 > Skip-Objekte, Standalone-Binaries) sind funktional ausreichend — ab jetzt
 > steht Robustheit vor neuen Features. Größere Feature-Wünsche (ACE Pro 2,
 > Home-Assistant-Integration vervollständigen, …) bleiben vorerst im Backlog.
 ### Neu
 - **Objekte überspringen (vor und während des Drucks):** Aus dem AnycubicSlicerNext-Workbench-Bundle rekonstruiert — der Kobra X kann das nativ über sein Protokoll, der Anycubic-Slicer bietet es bloß nicht im UI an. Die Bridge schon, in zwei Varianten:
  - **Vor dem Druck:** beim Starten eines Multi-Object-Drucks aus dem Browser-Tab hat der Filament-Dialog jetzt einen zusätzlichen Abschnitt „Objekte". Einzelne Objekte abwählen (oder Polygon direkt im Build-Plate-SVG anklicken) — sie werden vor dem Druck herausgenommen.
  - **Während des Drucks:** neuer ✂-Button im Dashboard (nur während eines laufenden Drucks sichtbar). Öffnet einen Dialog mit derselben interaktiven SVG-Vorschau — Teil anklicken, bestätigen, der Drucker druckt es nicht weiter. Bereits übersprungene Teile bleiben ausgegraut, der Dialog aktualisiert sich live damit man sieht welche schon weg sind.
 - **Filament-Dialog – farbige Kanal- und Slot-Marker (Issue #23):** Die GCode-Kanal-Nummer sitzt jetzt in einer farbigen Box links (Hintergrund = Kanal-Farbe, Auto-Kontrast-Text statt des alten kleinen Punktes), der zugewiesene AMS-Slot bekommt rechts neben dem Dropdown denselben Look — aktualisiert sich live wenn man die Auswahl ändert. Funktioniert mit 4 Kanälen; das Layout iteriert sauber für mehr, aber >4 echte Filament-Slots brauchen eine ACE-Pro-2-Box und sind ohne entsprechende Hardware nicht durchgängig testbar (geparkt als Feature-Request, Issues #22 und #23).
 ### Intern
 - Neue Helfer `kobrax_client.skip_objects(names)` / `query_skip_objects()`.
 - Neue Endpunkte: `GET /kx/files/{id}/objects`, `POST /kx/skip`, `POST /kx/skip/query`, `GET /kx/skip/state`.
 - SQLite-Schema: `gcode_files` bekommt die Spalten `objects_skip_parts` und `svg_image` (Auto-Migration auf bestehenden DBs).
 - `_on_file` extrahiert die vom Drucker gelieferte Objektliste + SVG-Vorschau und speichert sie pro Datei.
 - `_on_skip`-Callback verfolgt, welche Objekte der Drucker aktuell als übersprungen meldet.
 ---
 ## [0.9.9] – 2026-05-14
 ### Fixes
 - **„Failed to fetch"-Schleife in der UI (Issue #21):** Wenn die Web-UI über die LAN-IP geöffnet wurde, lieferte `/kx/printers` `bridge_url: http://localhost:7125` zurück. Der Browser machte daraufhin Cross-Origin-Requests von der LAN-IP nach `localhost` — die wurden vom Browser blockiert und produzierten eine Flut aus `TypeError: Failed to fetch`-Poll-Fehlern. Die Bridge liefert jetzt im Einzel-Drucker-Modus eine leere `bridge_url`, sodass das Frontend relative Pfade gegen dieselbe Origin wie die UI nutzt. Im Multi-Printer-Modus werden `localhost`/`127.0.0.1` als Bridge-Hosts herausgefiltert.
 - **Windows-EXE crasht beim Start (Issue #21):** Die v0.9.8-`kx-bridge.exe` wurde mit einer veralteten `config_loader.py` aus einem früheren Release gebaut und stürzte mit `AttributeError: module 'config_loader' has no attribute 'list_printers'` ab. `release.sh` synct jetzt `config_loader.py` zusammen mit den anderen Quellen ins Windows-Build-Repository.
 ---
 ## [0.9.8] – 2026-05-12
 ### Neu
 - **Multi-Printer in einer Bridge-Instanz:** Ein Prozess verwaltet jetzt mehrere Drucker gleichzeitig — N MQTT-Verbindungen + N HTTP-Listener (Ports 7125, 7126, …), geteilte SQLite + GCode-Store. Konfiguration über `[printer_1]`-, `[printer_2]`-… Sektionen in `config.ini`. Einzel-Modus (`[connection]`) funktioniert unverändert weiter. `docker-compose.yml` exposed einen Port-Range `7125-7130`.
 - **Drucker per UI hinzufügen:** „+ Drucker hinzufügen"-Button im Drucker-Tab — nur die IP eingeben, Zugangsdaten (Username, Passwort, Device-ID) werden automatisch vom Drucker geholt und entschlüsselt. Weitere Drucker bekommen den nächsten freien Port (7126, 7127, …).
 - **Drucker per UI entfernen:** „✕"-Button auf jeder Drucker-Karte mit Bestätigung — entfernt die `[printer_N]`-Sektion und nummeriert die übrigen um. Beim Entfernen des letzten Druckers wird auch `[connection]` geleert (leerer Zustand).
 - **GCode Store:** Hochgeladene Dateien werden in SQLite gespeichert, inkl. Thumbnail-Extraktion. Neue `/kx/files`-API.
 - **Browser-Tab:** Grid-Ansicht aller hochgeladenen Dateien — Thumbnail, Status-Badge (✓/✗), letzte Druckdauer, plus Suche, Filter und Sortierung.
 - **Druckhistorie:** Druckaufträge (Start/Ende/Status) werden in SQLite protokolliert, Status pro Datei im Browser-Tab sichtbar.
 - **Filament-Dialog:** Per-Kanal-Remapping vor dem Druckstart — jeder GCode-Farbkanal wird einem physischen AMS-Slot zugewiesen (wie im Anycubic Slicer). Verfügbar im Browser-Tab und im Upload-Banner.
 - **MMU-Emulation:** `GET /printer/objects/query?mmu` liefert eine Happy-Hare-kompatible Struktur, damit OrcaSlicers Filament-Sync die AMS-Slots erkennt.
 - **Drucker-Tab:** Live-Status aller Drucker-Instanzen, IP auf jeder Karte, „Wechseln →"-Button.
 - **Editierbarer Drucker-Name:** Eigener Name in den Einstellungen (gespeichert in `[bridge] printer_name`, hat Vorrang vor dem vom Drucker gemeldeten Namen).
 - **Standalone-tauglich:** Linux-Binary / Windows-EXE laufen ohne Docker — `config/` und `data/` liegen neben dem Programm (portabel). Erststart ohne konfigurierten Drucker zeigt den Drucker-Tab mit „+ Drucker hinzufügen" statt des Einstellungs-Dialogs.
 - **i18n:** Alle neuen UI-Elemente auf Deutsch und Englisch.
 ### Fixes
 - **CORS:** CORS-Middleware auf allen Endpunkten — Cross-Instance-Fetches in der Multi-Printer-UI funktionieren zuverlässig.
 - **Einstellungen / Update-Check** zeigen im Multi-Printer-Modus jetzt die aktive Bridge-Instanz (via `_apiUrl`).
 - **Bridge-Neustart:** Config-abhängige Umgebungsvariablen werden vor einem Neustart gelöscht (der Config-Loader cachte sie, wodurch Config-Änderungen erst nach einem Kaltstart sichtbar wurden). Der Neustart ist jetzt plattformabhängig: Docker/systemd → Prozess-Exit (Supervisor startet neu), Linux standalone → `os.execv`, Windows → detachter Subprozess.
 - **`--data-dir`-Default** ist jetzt plattformabhängig — der `/app/data`-Default greift nur in Docker (per `ENV` gesetzt), Standalone-Binaries nutzen `<exe-dir>/data`. Behebt einen Startup-Crash beim Ausführen ohne Docker.
 ---
 ## [0.9.7] – 2026-05-08
 ### Neu
 - **fetch_credentials-Tool:** Ruft MQTT-Credentials direkt vom Drucker per HTTP ab — kein laufender Anycubic Slicer nötig, nur die Drucker-IP. Linux-Binary und Windows-EXE im Release enthalten. (Beitrag von bebu, PR #19)
 ### Fixes
 - **Upload großer GCode-Dateien:** Dateien >1 MB wurden mit HTTP 413 abgelehnt — aiohttp `client_max_size` auf 256 MB erhöht
 - **Upload-Timeout:** Socket-Timeout nach GCode-Upload von 10s auf 120s erhöht — große Dateien führten zu einem Absturz der Bridge mit leerer Antwort während der Drucker noch verarbeitete
 ---
 ## [0.9.6] – 2026-05-02
 ### Neu
 - **Licht-Status-Synchronisierung:** Ein/Aus-Zustand und Helligkeit des Druckerlichts werden jetzt live über `light/report` MQTT gelesen — der Licht-Toggle in der UI spiegelt den echten Druckerstatus wider
 - **Zeit-Minicards:** Fortschritts-Panel zeigt jetzt drei Karten — Verstrichen, Restzeit und Slicer-Schätzung — sowie einen Layer-Badge neben dem Fortschrittsbalken
 - **Slicer-Schätzzeit aus GCode:** Geschätzte Druckzeit wird direkt aus der hochgeladenen GCode-Datei gelesen (OrcaSlicer: `; total estimated time:` am Dateiende, PrusaSlicer: `; estimated printing time` im Header)
 - **Erweiterte Druckerstatus-Strings:** `pausing`, `paused`, `resuming`, `resumed`, `stopping`, `stopped` hinzugefügt — fehlten bisher und ließen die UI rohe Status-Codes bei Pause/Fortsetzen/Stopp anzeigen
 ### Fixes
 - **file_ready-Banner:** Upload-Banner wird nach Stopp oder Abbruch eines Drucks nicht mehr angezeigt
 - **Zeitanzeige bei Stopp/Abbruch:** Verstrichen-, Restzeit- und Slicer-Schätzung werden auf null zurückgesetzt wenn ein Druck gestoppt oder abgebrochen wird
 - **start.sh:** `config/`-Verzeichnis und `config.ini.example` werden beim ersten Start automatisch angelegt wenn sie fehlen (Issue #15)
 ---
 ## [0.9.5] – 2026-05-01
 ### Neu
 - **Upload-Banner:** Nach „Nur hochladen" erscheint ein grüner Banner mit Dateiname — „▶ Druck starten" startet den Druck direkt, „✕ Abbrechen" schließt den Banner
 ### Fixes
 - **Auto-Print:** `auto_print` wurde nach dem Multipart-Loop immer auf `False` zurückgesetzt — OrcaSlicer „Hochladen und drucken" startete den Druck nie automatisch
 - **Thumbnail:** Vorschaubild wird jetzt auch bei „Nur hochladen" angezeigt — Bridge fragt `fileDetails` direkt nach dem Upload an
 - **Log Auto-Scroll:** Scroll-Position bleibt erhalten wenn Auto-Scroll deaktiviert ist — kein ungewollter Sprung nach oben mehr
 ---
 ## [0.9.4] – 2026-05-01
 ### Neu
 - **AMS-Slot-Editor:** Slot im AMS-Panel anklicken → Dialog mit Farbpicker und Material-Auswahl (Schnellbuttons: PLA/PETG/ABS/ASA/TPU/PA/PC/HIPS oder Freitext) direkt im Browser
 - **Verbessertes Log-Panel:** Vollständige MQTT-Payloads (keine Kürzung mehr), Richtungsfilter (Alle/RX/TX) und Topic-Schnellfilter (AMS / print / info / status)
 ### Fixes
 - **i18n:** Kamera-Placeholder-Text und Log-Richtungs-Button „Alle" werden jetzt korrekt beim Sprachwechsel übersetzt
 ---
 ## [0.9.3] – 2026-05-01
 ### Fixes
 - **Update-Check:** Stable-User erhalten keine Dev-Pre-Releases mehr — `STABLE_RELEASE_API` hatte `pre-release=true`, wodurch stabile Installationen Dev-Builds statt stabiler Releases fanden (Issue #14)
 - **Version nach Update:** `VERSION`-Datei wird jetzt im Docker-Image mitgeliefert (`COPY VERSION .`) — `_write_version()` benötigt eine vorhandene Datei, ohne die wurde die Version nach dem Self-Update nie aktualisiert (Issue #14)
 ### Neu
 - **Version im Header:** Laufende Version wird im Web-UI-Header neben dem Druckernamen angezeigt — kein Öffnen der Einstellungen nötig (Issue #14)
 ---
 ## [0.9.2] – 2026-04-29
 ### ⚠️ Breaking Change: Konfiguration wechselt von `.env` zu `config/config.ini`
 **Migration erfolgt automatisch** beim ersten Start — keine manuelle Aktion nötig.
 - Einstellungen werden ab sofort aus `config/config.ini` gelesen statt aus `.env`
 - Beim ersten Start ohne `config.ini` wird die Datei automatisch aus `.env` erstellt
 - **Docker:** Volume `./config:/app/config` in `docker-compose.yml` ist der persistente Speicherort — Einstellungen überleben `docker-compose restart` und Updates
 - **Standalone:** `config/config.ini` liegt neben der Binary und wird bei Updates nicht überschrieben
 - `.env` bleibt als read-only Fallback gemountet — kann liegen bleiben
 - Zum manuellen Anlegen einer `config.ini`: Vorlage unter `config/config.ini.example`
 ### Neu
 - **Persistente Einstellungen:** `config/config.ini` ersetzt `.env` — Einstellungen gehen nach `docker-compose restart` nicht mehr verloren (Issue #9)
 - **Verbindungsfehler-Banner:** Roter Banner oben in der Web-UI wenn MQTT-Verbindung fehlschlägt (z.B. falsches Passwort, Drucker nicht erreichbar) (Issue #11)
 - **Slicer-Schätzzeit:** Geschätzte Gesamtdruckzeit aus dem GCode-Header wird im Fortschritts-Panel angezeigt
 ### Fixes
 - README: OrcaSlicer-Verbindung explizit mit `http://` und Port `:7125` dokumentiert (Issue #12)
 - README: Direkter Download-Link für `extract_credentials` auf Gitea-Releases (Issue #13)
 ---
 ## [0.9.1-dev] – laufend (dev-Branch)
 ### Neu
 - **Dev-Branch-Infrastruktur:** Versionsschema `0.9.1-dev+<hash>` — jeder Build eindeutig identifizierbar
 - **Separater Update-Kanal:** Dev-Versionen prüfen auf Gitea Pre-Releases mit `-dev+` im Tag
 - **AMS-Slot-Auswahl:** Einstellung „Standard-Slot (Einfarbdruck)" im Settings-Modal — fixiert einen bestimmten AMS-Kanal oder Auto (alle belegten Slots)
 - **Auto-Leveling:** Checkbox im Settings-Modal — steuert `task_settings.auto_leveling` beim Druckstart
 - **MQTT-Logging:** Strukturiertes TX/RX-Log mit Duplikat-Filter (`kobrax.mqtt` Logger)
 - **Server-Log im Browser:** Live-Stream via SSE (`/api/log/stream`) — alle Server-Logs erscheinen im Log-Tab der UI
 - **Log-Tab Verbesserungen:**
  - Auto-Scroll ein/aus — deaktiviert sich beim manuellen Hochscrollen, Button zum Reaktivieren
  - Textfilter — Live-Filterung der Log-Einträge
  - Error-Badge — roter Zähler im Tab-Button bei Fehlern/Warnungen
  - Clear-Button — Buffer leeren
  - Download-Button — letzte 500 Einträge als `kx-bridge.log`
  - Log-Fenster füllt den gesamten verfügbaren Platz (statt fester Höhe 160px)
 - **Log-Buffer:** 500 Einträge (Server + Browser vereinheitlicht)
 - **Changelog im Update-Dialog:** Release-Notes aus Gitea werden direkt im Update-Dialog angezeigt
 - **Slicer-Schätzzeit:** Geschätzte Gesamtdruckzeit aus dem GCode-Header im Fortschritts-Panel

 ## [0.9.1-beta15] – 2026-04-26
 ### Fixes
 - AMS: Leere Slots werden beim Druckstart übersprungen — kein `filament runout` mehr bei unbelegten Kanälen (Issue #5)
 - AMS: Material-Typ wird jetzt korrekt aus dem Drucker-Protokoll gelesen (Feld `type` statt `material_type`)
 - AMS UI: Leere Slots werden grau/transparent mit „Leer"-Label dargestellt
 ---
 ## [0.9.1-beta14] – 2026-04-26

 # Changelog
 ## [0.9.12] – 2026-05-20
 ### Fixes
 - **Pause state** is now read correctly: the bridge was looking at the device-level
  state instead of the nested print-job state, so a paused print sometimes still
  showed as printing. Layer/progress/remaining-time are now also taken from the
  job report.
 ### Internal
 - Frontend (HTML/CSS/JS) extracted from the Python file into `web/index.html`,
  bundled back in at build time — easier to maintain, no change for users.
 ### Docs
 - Linked the community **Home Assistant integration** by @gangoke.
 ## [0.9.11] – 2026-05-20
 ### New
 - **ACE Pro 2 support (experimental, community contribution by @gangoke, PR #26):** the bridge now auto-detects the filament hardware and adapts:
  - **Modes:** `toolhead` (no ACE, stock 4-slot box), `ace_direct` (one ACE Pro 2 directly on the toolhead), `ace_hub` (up to 4 ACE units on the slot-4 hub) — up to **19 slots** total.
  - **AMS auto-refill** toggle.
  - **Dryer:** temperature/humidity monitor, start/stop/temp/duration control, with material presets configurable in a new `[ace_dry_presets]` config section (PLA, PLA+, PETG, TPU, ABS/ASA, PA/PC + 3 custom).
  - **UI:** filament section scales to 19 slots, mode label, loaded slot is green-outlined with a load/unload pulse animation, unload/load straight from the slot-edit dialog.
  - **GCode color mapping:** ACE2-aware, color-from-GCode fix, inconsistency notifier when the mapping doesn't match the objects, better default mapping.
 > **⚠️ Experimental:** the ACE Pro 2 hardware paths were developed and tested by the contributor with a single ACE2 unit; the 2–4 unit hub configurations are theoretical and untested on real hardware. We don't have ACE2 hardware to verify against either. The standard `toolhead` (no-ACE) path was verified live against a real Kobra X here. If you run a multi-ACE setup, please report back via Issues.
 ### Fixes
 - **Happy Hare MMU emulation:** only populated slots are now synced — no placeholder for empty slots (aligns with OrcaSlicer PR #13372).
 - **GCode color dialog** no longer shows the previously-uploaded file's data after a new upload.
 ---
 ## [0.9.10] – 2026-05-17
 > **Heads-up:** with this release the focus shifts from new features to
 > **stabilization and bug-fixing**. The core flows (multi-printer, add/remove,
 > filament dialog, skip objects, standalone binaries) are feature-complete
 > enough — from now on the priority is making them rock-solid before adding
 > more on top. Bigger feature requests (ACE Pro 2, Home Assistant integration
 > completeness, …) stay on the backlog for now.
 ### New
 - **Skip objects (pre-print and mid-print):** Reverse-engineered from the AnycubicSlicerNext Workbench bundle — the Kobra X actually supports object skipping over its native protocol, but the Anycubic slicer doesn't expose it. The bridge does now, in both flavors:
  - **Pre-print:** when starting a multi-object print from the Browser tab, the filament dialog now has an additional "Objects" section. Uncheck individual objects (or click the polygon directly on the build-plate SVG preview) and they're stripped from the print before it starts.
  - **Mid-print:** new ✂ button on the dashboard (only visible during an active print). Opens a dialog with the same interactive SVG preview — click a part to mark it for skipping, hit confirm, and the printer drops it from the rest of the run. Already-skipped parts stay greyed out and the dialog refreshes live so you can see which ones are gone.
 - **Filament dialog – colored channel and slot markers (Issue #23):** the GCode channel number now sits in a colored box on the left (background = channel color, auto-contrast text instead of the old tiny dot), and the assigned AMS slot gets the same treatment on the right of the dropdown — updates live as you change the selection. Plays well with 4 channels; the layout iterates so more channels render correctly, but >4 actual filament slots still need an ACE Pro 2 hub to be testable end-to-end (parked as a feature request, Issues #22 and #23).
 ### Internal
 - New `kobrax_client.skip_objects(names)` / `query_skip_objects()` helpers.
 - New endpoints: `GET /kx/files/{id}/objects`, `POST /kx/skip`, `POST /kx/skip/query`, `GET /kx/skip/state`.
 - SQLite schema: `gcode_files` gained `objects_skip_parts` and `svg_image` columns (auto-migrates on existing DBs).
 - `_on_file` now extracts the printer-provided object list + SVG preview and persists them per file.
 - `_on_skip` callback tracks which objects the printer reports as currently skipped.
 ---
 ## [0.9.9] – 2026-05-14
 ### Fixes
 - **"Failed to fetch" loop in the UI (Issue #21):** When the web UI was opened via the LAN IP, `/kx/printers` was returning `bridge_url: http://localhost:7125`, which caused the browser to fire cross-origin requests from the LAN IP to `localhost` — these were silently blocked, producing a flood of `TypeError: Failed to fetch` poll errors. The bridge now sends an empty `bridge_url` in single-printer mode so the frontend uses relative paths against the same origin as the UI. In multi-printer mode, `localhost`/`127.0.0.1` are filtered out as bridge hosts.
 - **Windows EXE startup crash (Issue #21):** The v0.9.8 `kx-bridge.exe` was built with a stale `config_loader.py` from an earlier release and crashed on startup with `AttributeError: module 'config_loader' has no attribute 'list_printers'`. `release.sh` now syncs `config_loader.py` into the Windows build repository together with the other source files.
 ---
 ## [0.9.8] – 2026-05-12
 ### New
 - **Multi-printer in a single bridge instance:** One process now manages multiple printers — N MQTT connections + N HTTP listeners (ports 7125, 7126, …), shared SQLite + GCode store. Configure via `[printer_1]`, `[printer_2]` … sections in `config.ini`. Single-printer mode (`[connection]` only) keeps working unchanged. `docker-compose.yml` exposes a port range `7125-7130`.
 - **Add printer from the UI:** "+ Add printer" button in the Printers tab — just enter the printer IP, the credentials (username, password, device ID) are fetched and decrypted from the printer automatically. Adding more printers assigns the next free port (7126, 7127, …).
 - **Remove printer from the UI:** "✕" button on each printer card with a confirmation dialog — removes the `[printer_N]` section and renumbers the rest. Removing the last printer clears `[connection]` too, leaving an empty state.
 - **GCode Store:** Uploaded files are persisted in SQLite with thumbnail extraction. New `/kx/files` API.
 - **Browser tab:** Grid view of all uploaded files — thumbnail, status badge (✓/✗), last print duration, plus search, filter and sort.
 - **Print history:** Print jobs (start/end/status) are recorded in SQLite, status shown per file in the Browser tab.
 - **Filament dialog:** Per-channel remapping before print start — assign each GCode color channel to a physical AMS slot (like the Anycubic Slicer does). Available in the Browser tab and the upload banner.
 - **MMU emulation:** `GET /printer/objects/query?mmu` returns a Happy-Hare-compatible structure so OrcaSlicer's filament sync detects the AMS slots.
 - **Printers tab:** Live status of all printer instances, IP shown on each card, "Switch →" button.
 - **Editable printer name:** Set a custom name in Settings (stored in `[bridge] printer_name`, takes precedence over the MQTT-reported name).
 - **Standalone friendly:** Linux binary / Windows EXE run without Docker — `config/` and `data/` are placed next to the executable (portable). First start with no printer configured shows the Printers tab with "+ Add printer" instead of the settings modal.
 - **i18n:** All new UI elements available in German and English.
 ### Fixes
 - **CORS:** CORS middleware added to all endpoints — cross-instance fetches in the multi-printer UI work reliably.
 - **Settings / update check** now reflect the active bridge instance in multi-printer mode (via `_apiUrl`).
 - **Bridge restart:** Config-dependent environment variables are cleared before a restart (the config loader cached them, which made config changes invisible until the next cold start). Restart is now platform-aware: Docker/systemd → process exit (supervisor restarts), Linux standalone → `os.execv`, Windows → detached subprocess.
 - **`--data-dir` default** is now platform-dependent — the `/app/data` default only applies inside Docker (set via `ENV`), standalone binaries use `<exe-dir>/data`. Fixes a startup crash when running the binary without Docker.
 ---
 ## [0.9.7] – 2026-05-08
 ### New
 - **fetch_credentials tool:** Fetches and decrypts MQTT credentials directly from the printer via HTTP — no running Anycubic Slicer required, only the printer IP needed. Linux binary and Windows EXE included in release. (Contributed by bebu, PR #19)
 ### Fixes
 - **Large GCode upload:** Files >1 MB were rejected with HTTP 413 — aiohttp `client_max_size` raised to 256 MB
 - **Upload timeout:** Socket timeout after GCode upload raised from 10s to 120s — large files caused the bridge to crash with an empty response while the printer was still processing
 ---
 ## [0.9.6] – 2026-05-02
 ### New
 - **Light status sync:** Light on/off state and brightness are now read live from the printer via `light/report` MQTT message — the light toggle in the UI reflects the actual printer state
 - **Time mini-cards:** Progress panel now shows three cards — Elapsed, Remaining and Slicer estimate — with a layer counter badge next to the progress bar
 - **Slicer estimate from GCode:** Estimated print time is parsed directly from the uploaded GCode file (OrcaSlicer: `; total estimated time:` at end of file, PrusaSlicer: `; estimated printing time` in header)
 - **Extended printer status strings:** Added `pausing`, `paused`, `resuming`, `resumed`, `stopping`, `stopped` states — previously missing, causing the UI to show raw status codes during pause/resume/stop transitions
 ### Fixes
 - **file_ready banner:** Upload banner is no longer shown after print stop or cancel
 - **Timers on stop/cancel:** Elapsed, remaining and slicer estimate times are reset to zero when a print is stopped or cancelled
 - **start.sh:** `config/` directory and `config.ini.example` are now created automatically on first run if missing (Issue #15)
 ---
 ## [0.9.5] – 2026-05-01
 ### New
 - **Upload banner:** After "Upload only", a green banner appears with the filename — "▶ Start Print" starts the print directly, "✕ Cancel" dismisses the banner
 ### Fixes
 - **Auto-print:** `auto_print` was always reset to `False` after the multipart loop — OrcaSlicer "Upload and print" never started the print automatically
 - **Thumbnail:** Preview image is now shown after "Upload only" — bridge requests `fileDetails` immediately after upload
 - **Log auto-scroll:** Scroll position is preserved when auto-scroll is disabled — no more unwanted jump to top
 ---
 ## [0.9.4] – 2026-05-01
 ### New
 - **AMS slot editor:** Click any slot in the AMS panel to open an edit dialog — set color (color picker) and material (preset buttons: PLA/PETG/ABS/ASA/TPU/PA/PC/HIPS or free text) directly from the browser
 - **Improved log panel:** Full MQTT payloads (no truncation), direction filter (All/RX/TX) and topic quick-filter buttons (AMS / print / info / status)
 ### Fixes
 - **i18n:** Camera placeholder text and log direction "All" button now correctly translated on language switch
 ---
 ## [0.9.3] – 2026-05-01
 ### Fixes
 - **Update check:** Stable users no longer receive dev pre-releases — `STABLE_RELEASE_API` had `pre-release=true` which caused stable installs to find dev builds instead of stable releases (Issue #14)
 - **Version after update:** `VERSION` file is now included in the Docker image (`COPY VERSION .`) — `_write_version()` requires the file to exist, without it the version was never updated after self-update (Issue #14)
 ### New
 - **Version in header:** Running version shown in the Web-UI header next to the printer name — no need to open Settings to check (Issue #14)
 ---
 ## [0.9.2] – 2026-04-29
 ### ⚠️ Breaking Change: Configuration moves from `.env` to `config/config.ini`
 **Migration is automatic** on first start — no manual action required.
 - Settings are now read from `config/config.ini` instead of `.env`
 - On first start without `config.ini`, the file is created automatically from `.env`
 - **Docker:** Volume `./config:/app/config` in `docker-compose.yml` is the persistent storage — settings survive `docker-compose restart` and updates
 - **Standalone:** `config/config.ini` sits next to the binary and is not overwritten on update
 - `.env` stays mounted read-only as a migration source — you can leave it in place
 - To create a `config.ini` manually: copy `config/config.ini.example`
 ### New
 - **Persistent settings:** `config/config.ini` replaces `.env` — settings no longer lost after `docker-compose restart` (Issue #9)
 - **Connection error banner:** Red banner at the top of the Web-UI when MQTT connection fails (e.g. wrong password, printer unreachable) (Issue #11)
 - **Slicer estimated time:** Estimated total print time from GCode header shown in the progress panel
 ### Fixes
 - README: OrcaSlicer connection documented explicitly with `http://` and port `:7125` (Issue #12)
 - README: Direct download link for `extract_credentials` pointing to Gitea releases (Issue #13)
 ---
 ## [0.9.1-dev] – ongoing (dev branch)
 ### New
 - **Dev branch infrastructure:** Version scheme `0.9.1-dev+<hash>` — every build uniquely identifiable
 - **Separate update channel:** Dev versions check for Gitea pre-releases with `-dev+` in the tag
 - **AMS slot selection:** Setting "Default slot (single color)" in the Settings modal — pins a specific AMS channel or Auto (all loaded slots)
 - **Auto-leveling:** Checkbox in Settings modal — controls `task_settings.auto_leveling` on print start
 - **MQTT logging:** Structured TX/RX log with duplicate filter (`kobrax.mqtt` logger)
 - **Server log in browser console:** Live stream via SSE (`/api/log/stream`) — all server logs appear in the Log tab
 - **Log tab improvements:**
  - Auto-scroll on/off — disables automatically on manual scroll-up, button to re-enable
  - Text filter — live filtering of log entries
  - Error badge — red counter on the tab button when errors/warnings occur while on another tab
  - Clear button — empty the buffer
  - Download button — last 500 entries as `kx-bridge.log`
  - Log window now fills all available space (instead of fixed 160px height)
 - **Log buffer:** 500 entries (server + browser unified)
 - **Changelog in update dialog:** Release notes from Gitea loaded and shown directly in the update dialog
 - **Slicer estimated time:** Estimated total print time from GCode header shown in the progress panel
 ---
 ## [0.9.1-beta15] – 2026-04-26
 ### Fixes
 - AMS: Empty slots are skipped on print start — no more `filament runout` for unloaded channels (Issue #5)
 - AMS: Material type is now correctly read from the printer protocol (field `type` instead of `material_type`)
 - AMS UI: Empty slots shown grey/transparent with "Empty" label
 ---

                    GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007
 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
                            Preamble
  The GNU General Public License is a free, copyleft license for
 software and other kinds of works.
  The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
 the GNU General Public License is intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
 software for all its users.  We, the Free Software Foundation, use the
 GNU General Public License for most of our software; it applies also to
 any other work released this way by its authors.  You can apply it to
 your programs, too.
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
  To protect your rights, we need to prevent others from denying you
 these rights or asking you to surrender the rights.  Therefore, you have
 certain responsibilities if you distribute copies of the software, or if
 you modify it: responsibilities to respect the freedom of others.
  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must pass on to the recipients the same
 freedoms that you received.  You must make sure that they, too, receive
 or can get the source code.  And you must show them these terms so they
 know their rights.
  Developers that use the GNU GPL protect your rights with two steps:
 (1) assert copyright on the software, and (2) offer you this License
 giving you legal permission to copy, distribute and/or modify it.
  For the developers' and authors' protection, the GPL clearly explains
 that there is no warranty for this free software.  For both users' and
 authors' sake, the GPL requires that modified versions be marked as
 changed, so that their problems will not be attributed erroneously to
 authors of previous versions.
  Some devices are designed to deny users access to install or run
 modified versions of the software inside them, although the manufacturer
 can do so.  This is fundamentally incompatible with the aim of
 protecting users' freedom to change the software.  The systematic
 pattern of such abuse occurs in the area of products for individuals to
 use, which is precisely where it is most unacceptable.  Therefore, we
 have designed this version of the GPL to prohibit the practice for those
 products.  If such problems arise substantially in other domains, we
 stand ready to extend this provision to those domains in future versions
 of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
 States should not allow patents to restrict development and use of
 software on general-purpose computers, but in those that do, we wish to
 avoid the special danger that patents applied to a free program could
 make it effectively proprietary.  To prevent this, the GPL assures that
 patents cannot be used to render the program non-free.
  The precise terms and conditions for copying, distribution and
 modification follow.
                       TERMS AND CONDITIONS
  0. Definitions.
  "This License" refers to version 3 of the GNU General Public License.
  "Copyright" also means copyright-like laws that apply to other kinds of
 works, such as semiconductor masks.
  "The Program" refers to any copyrightable work licensed under this
 License.  Each licensee is addressed as "you".  "Licensees" and
 "recipients" may be individuals or organizations.
  To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.
  A "covered work" means either the unmodified Program or a work based
 on the Program.
  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
  1. Source Code.
  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.
  The Corresponding Source for a work in source code form is that
 same work.
  2. Basic Permissions.
  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.
  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Use with the GNU Affero General Public License.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU Affero General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the special requirements of the GNU Affero General Public License,
 section 13, concerning interaction through a network will apply to the
 combination as such.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software
 Foundation.  If the Program does not specify a version number of the
 GNU General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
 versions of the GNU General Public License can be used, that proxy's
 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.
  Later license versions may give you additional or different
 permissions.  However, no additional obligations are imposed on any
 author or copyright holder as a result of your choosing to follow a
 later version.
  15. Disclaimer of Warranty.
  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 SUCH DAMAGES.
  17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
 above cannot be given local legal effect according to their terms,
 reviewing courts shall apply local law that most closely approximates
 an absolute waiver of all civil liability in connection with the
 Program, unless a warranty or assumption of liability accompanies a
 copy of the Program in return for a fee.
                     END OF TERMS AND CONDITIONS
            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.
    You should have received a copy of the GNU General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If the program does terminal interaction, make it output a short
 notice like this when it starts in an interactive mode:
    <program>  Copyright (C) <year>  <name of author>
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, your program's commands
 might be different; for a GUI interface, you would use an "about box".
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.
 For more information on this, and how to apply and follow the GNU GPL, see
 <https://www.gnu.org/licenses/>.
  The GNU General Public License does not permit incorporating your program
 into proprietary programs.  If your program is a subroutine library, you
 may consider it more useful to permit linking proprietary applications with
 the library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.  But first, please read
 <https://www.gnu.org/licenses/why-not-lgpl.html>.

 # NOTICE
 This repository contains code licensed under the **GNU General Public License
 v3.0** (see [LICENSE](LICENSE)) and material that is **not** covered by that
 license. Read this file before forking, distributing, or building from source.
 ## What is GPLv3-licensed
 The original work in this repository:
 - `bridge/` — Bridge daemon, MQTT client, web UI, configuration loader,
  protocol implementation
 - `tools/` — `extract_credentials`, `fetch_credentials` utilities
 - `_archive/tools/kx_printer_emulator.py` — printer emulator
 - `Dockerfile`, `docker-compose.yml`, `release.sh`, build scripts
 - Documentation files (`README*`, `CHANGELOG*`, `_archive/RE/06_docs/*`)
 - `kobra_x_orcaslicer_preset.zip` — slicer profile derived from public OrcaSlicer
  presets, adapted for the Kobra X
 You are free to use, modify and redistribute this code under the terms of
 GPLv3 — including for commercial purposes — provided downstream forks remain
 under GPLv3 and source is made available to recipients.
 ## What is **not** GPLv3-licensed
 The following items are **third-party material**, included here only for
 **interoperability purposes** as permitted under §69e UrhG (German Copyright
 Act; equivalent: EU Software Directive Art. 6, US fair-use for reverse
 engineering for interoperability):
 - **`bridge/anycubic_slicer.crt`** and **`bridge/anycubic_slicer.key`** —
  TLS client certificate and private key extracted from Anycubic Slicer Next
  binaries. Copyright remains with Anycubic / their respective authors.
  Included solely to enable the bridge to authenticate against the LAN MQTT
  broker that runs on a Kobra X printer the end-user already owns. No
  ownership claim is made.
 - **MQTT protocol structures, payload formats and signature algorithms** —
  reverse-engineered from `Workbench.dll` / `cloud_mqtt.dll` of the Anycubic
  Slicer Next application. The protocol itself is documented in
  `_archive/RE/06_docs/` for transparency. Any reproduction of code or
  protocol details serves interoperability only.
 - **AMS material naming, slot numbering, GCode markers (`EXCLUDE_OBJECT_*`)**
  — follow conventions established by Anycubic and the wider Klipper
  ecosystem; usage here is purely interoperability-driven.
 ## What this means for forks
 If you fork KX-Bridge:
 1. **You must keep this `NOTICE.md` and `LICENSE` file** in your fork.
 2. Your modifications and additions to the bridge code, UI, tools and docs
   inherit GPLv3 — they must be made available under the same license if you
   distribute them.
 3. The third-party material listed above is **not** something you can
   relicense; it stays under the original (implicit) rights of its owners.
 4. Removing the certificates and rebuilding them from your own Anycubic
   Slicer installation is the safest path for redistribution if you are
   unsure about the §69e situation in your jurisdiction.

 ## 🚀 Schnellstart
 ### 1. Drucker vorbereiten
 LAN-Modus am Kobra X aktivieren:
 **Drucker-Display → Einstellungen → LAN-Modus aktivieren**
 ### 2. Bridge starten
 **Docker (empfohlen):**
 ```bash
 docker compose up -d
 ```
 **Linux-Binary (kein Docker):**
 ```bash
 chmod +x kx-bridge && ./kx-bridge
 ```
 **Windows-EXE (kein Docker):**
 ```
 kx-bridge.exe
 ```
 > `config\` und `data\` werden neben der EXE angelegt — portabel.
 > Bei Linux- und Windows-Binary liegen `config/` und `data/` (Einstellungen, SQLite,
 > GCode-Store) jeweils neben dem Programm. Einfach den ganzen Ordner kopieren = umziehen.
 **Python direkt:**
 ```bash
 pip install -r bridge/requirements.txt
 python bridge/kobrax_moonraker_bridge.py
 ```
 ### 3. Drucker einrichten
 Web-UI öffnen: **`http://BRIDGE-IP:7125`**
 Beim Erststart erscheint der **Drucker-Tab** mit *„+ Drucker hinzufügen"* — einfach die
 IP-Adresse des Druckers eingeben, der Rest (Username, Passwort, Device-ID) wird automatisch
 vom Drucker geholt und entschlüsselt. Fertig.
 > Mehrere Drucker? Einfach mehrfach *„+ Drucker hinzufügen"* — jeder bekommt seinen eigenen
 > Port (7125, 7126, …) und ist im Header-Dropdown auswählbar.
 ### 4. OrcaSlicer verbinden
 Drucker → Verbindungstyp **Moonraker** → Host: `http://BRIDGE-IP:7125`
 > ⚠️ Verbindungstyp muss **Moonraker** sein (nicht „Bambu" oder „Klipper").
 > Vollständige URL inkl. `http://` und Port `:7125` im Host-Feld eintragen.

 ## 🔧 Zugangsdaten manuell ermitteln
 Normalerweise nicht nötig — *„+ Drucker hinzufügen"* macht das automatisch. Falls doch:
 ```bash
 fetch_credentials --ip 192.168.x.x --write-config
 ```
 Holt die Zugangsdaten per HTTP direkt vom Drucker und schreibt sie in `config/config.ini`.
 Nur die Drucker-IP nötig, kein Slicer.
 Alternativ (wenn die IP unbekannt ist): AnycubicSlicerNext öffnen, Drucker verbinden,
 dann `extract_credentials` ausführen → gibt Username, Passwort, Device-ID und IP aus.

 ## ⚙️ Nützliche Befehle
 ```bash
 docker compose logs -f      # Logs anzeigen
 docker compose down         # Bridge stoppen
 docker compose up -d --build # Bridge neu bauen & starten (nach Update)
 ```
 ---
 ## 🩹 Troubleshooting
 <details>
 <summary><b>"Falsche MQTT-Zugangsdaten" beim Start</b></summary>
 - Drucker über *„+ Drucker hinzufügen"* erneut hinzufügen, oder
  `fetch_credentials --ip <ip> --write-config` ausführen und Bridge neu starten
 - Nur die IP-Adresse eingeben, ohne Port (✗ `192.168.1.102:9883` → ✓ `192.168.1.102`)
 </details>
 <details>
 <summary><b>Drucker nicht gefunden / kein LAN-Modus</b></summary>
 - Am Drucker-Display: Einstellungen → LAN-Modus aktivieren
 - Drucker und Bridge müssen im selben Netzwerk sein
 </details>
 <details>
 <summary><b>Docker: Permission denied</b></summary>
 ```bash
 sudo usermod -aG docker $USER   # danach aus- und wieder einloggen
 ```
 </details>
 <details>
 <summary><b>Upgrade von 0.9.1 oder älter</b></summary>
 Ab 0.9.2 speichert KX-Bridge die Einstellungen in `config/config.ini` statt `.env`.
 Die Migration läuft automatisch beim ersten Start nach dem Upgrade — keine Aktion nötig.
 </details>
 ---
 ## 🔒 Sicherheit
 - Die Bridge ist im lokalen Netzwerk unter `http://<host-IP>:7125` erreichbar — **nicht** ins Internet exposen
 - `config/config.ini` enthält Drucker-Zugangsdaten — nicht öffentlich teilen
 - Die Zugangsdaten geben **keinen** Zugriff auf Anycubic-Cloud-Dienste

 # KX-Bridge – Anycubic Kobra X Moonraker Bridge
 **Version:** 0.9.1-beta10
 **Status:** Public Beta – suitable for home users, feedback welcome
 KX-Bridge is a Moonraker-compatible HTTP/WebSocket bridge for the **Anycubic Kobra X** 3D printer. It allows you to control the printer through OrcaSlicer and other Moonraker-compatible software — no Klipper, no Raspberry Pi required.
 ---
 ## What's supported?
 - Printer status (temperature, progress, state)
 - File transfer and print start
 - Print control: pause, resume, cancel
 - Temperature control during an active print
 - Print speed (Silent / Normal / Sport)
 - AMS filament change (load / unload)
 - Light and fan control
 - Web UI with dashboard, temperature cards, axis control, and camera view
 - Settings and self-update directly in the browser (⚙ menu)
 - OrcaSlicer connection (Moonraker protocol)
 ---
 ## Requirements
 - Anycubic Kobra X on your local network, with **LAN mode enabled** (printer menu → enable LAN mode)
 - Printer MQTT credentials (→ see [Extracting credentials](#extracting-credentials))
 - Docker **or** Python 3.9+ **or** the pre-built Linux binary
 ---
 ## Quick start – Docker (recommended)
 ```bash
 # 1. Start the bridge
 ./start.sh
 ```
 `start.sh` builds the Docker image automatically on first run and starts the bridge.
 ```
 # 2. Open the web UI: http://BRIDGE-IP:7125
 #    → Settings (⚙) open automatically on first start
 #    → Enter your credentials (→ see Extracting credentials)
 # 3. In OrcaSlicer: add printer → "Moonraker" → http://BRIDGE-IP:7125
 ```
 Check logs:
 ```bash
 docker-compose logs -f
 ```
 Stop:
 ```bash
 docker-compose down
 ```
 ---
 ## Quick start – Binary (Linux)
 ```bash
 chmod +x kx-bridge
 ./kx-bridge
 ```
 Open the web UI: `http://localhost:7125`  
 → Settings (⚙) open automatically and guide you through the initial setup.
 ---
 ## Quick start – Python directly
 ```bash
 pip install aiohttp
 python kobrax_moonraker_bridge.py
 ```
 Open the web UI: `http://localhost:7125`  
 → Settings (⚙) open automatically on first start.
 ---
 ## Extracting credentials
 The MQTT credentials are printer-specific and are generated on first connection with AnycubicSlicerNext. The `extract_credentials` tool reads them from the memory of the running slicer.
 **Requirement:** AnycubicSlicerNext must be running and connected to the printer (printer status is shown).
 ### Windows
 ```
 extract_credentials.exe
 ```
 ### Linux
 ```bash
 chmod +x extract_credentials
 ./extract_credentials
 ```
 ### Output
 ```
 [*] Process found: AnycubicSlicerNext.exe (PID 1234)
 [*] 1986 memory segments read (738.8 MB)
 [*] Analyzing ... 100% (739 MB)

 ```
 Enter the displayed values in the bridge settings:  
 Open web UI → **⚙ Settings** → fill in the fields → **Save & Restart**
 > If the result looks uncertain: `--verbose` shows all found candidates.
 All credentials are **processed locally only** — nothing is sent to external servers.
 ---
 ## Configuration (.env)
 ```env
 PRINTER_IP=192.168.x.x       # Printer IP address
 MQTT_PORT=9883                # Default, do not change
 MQTT_USERNAME=userXXXXXXXX   # Starts with "user"
 MQTT_PASSWORD=XXXXXXXXXXXXXX  # ~15 characters, mixed case
 DEVICE_ID=xxxxxxxx...         # 32-character hex string
 MODE_ID=20030                 # Kobra X default
 ```
 ---
 ## OrcaSlicer setup
 1. Add printer → **Anycubic Kobra X** (or generic Klipper printer)
 2. Connection type: **Moonraker**
 3. Host: `http://BRIDGE-HOST:7125`
 4. Test connection → should show "Online"
 ---
 ## Web UI
 The bridge serves a web interface at `http://BRIDGE-HOST:7125`:
 | Section | Function |
 |---------|----------|
 | Dashboard | Printer status, progress, temperature overview |
 | Temperatures | Set nozzle and bed temperature directly |
 | Motion | X/Y/Z movement, motor release |
 | Print Speed | Silent / Normal / Sport |
 | Fan / Light | Fan speed and work light |
 | AMS | Load / unload filament |
 | Camera | Live preview (if supported by printer) |
 | ⚙ Settings | MQTT credentials, poll interval, self-update |
 ### Self-update
 The ⚙ menu in the web UI lets you check for new versions and update the bridge in place — no reinstallation needed. After the download the bridge restarts automatically with the new version.
 ---
 ## bridge.sh (Linux service manager)
 ```bash
 ./bridge.sh start    # Start bridge in background
 ./bridge.sh stop     # Stop bridge
 ./bridge.sh restart  # Restart
 ./bridge.sh status   # Check status and port
 ./bridge.sh log 50   # Show last 50 log lines
 ```
 ---
 ## Printer states
 The bridge translates internal Kobra states into Moonraker-compatible states:
 | Kobra state | Meaning |
 |-------------|---------|
 | free | Ready |
 | printing / busy | Printing |
 | pausing / paused | Paused |
 | resuming / resumed | Resuming |
 | stopping / stoped | Stopping |
 | finished | Complete |
 | canceled | Cancelled |
 | failed | Error |
 ---
 ## Troubleshooting
 **Port 7125 already in use:**
 ```bash
 ./bridge.sh stop    # or: fuser -k 7125/tcp
 ./bridge.sh start
 ```
 **Invalid credentials / connection refused:**
 - Start AnycubicSlicerNext, connect to the printer, then run `extract_credentials` again
 - If the result looks uncertain: `extract_credentials --verbose` shows all candidates
 - Manually enter the correct candidate in `.env` and restart the bridge
 **Temperature changes are ignored:**
 - During an active print, temperature changes are sent via a separate channel — this is normal and the bridge handles it automatically.
 **Docker: Permission denied:**
 ```bash
 sudo usermod -aG docker $USER
 # Log out and back in
 ```
 **Docker: .env not found:**
 ```bash
 # .env must be in the same directory as docker-compose.yml
 cp .env.example .env && nano .env
 ```
 ---
 ## Logs
 ```bash
 # Docker
 docker compose logs -f kx-bridge
 # Binary / Python
 tail -f /tmp/bridge.log   # when using bridge.sh
 ```
 ---
 ## Security notes
 - The bridge binds to `0.0.0.0:7125` by default — use on your local network only
 - `.env` contains printer credentials — do not share publicly
 - The credentials are printer-specific and have no access to Anycubic cloud services

-## Voraussetzungen
+## 🚀 Quick Start
- Anycubic Kobra X im lokalen Netzwerk, mit aktiviertem **LAN-Modus** (Drucker-Menü → LAN-Modus einschalten)
+### 1. Prepare the printer
- MQTT-Credentials des Druckers (→ siehe [Credentials extrahieren](#credentials-extrahieren))
+
- Docker **oder** Python 3.9+ **oder** direkt die Linux-Binary
+Enable LAN mode on the Kobra X:
 **Printer display → Settings → Enable LAN mode**
 ### 2. Start the bridge
 **Docker (recommended):**
 ```bash
 docker compose up -d
 ```
 **Linux binary (no Docker):**
 ```bash
 chmod +x kx-bridge && ./kx-bridge
 ```
 **Windows EXE (no Docker):**
 ```
 kx-bridge.exe
 ```
 > `config\` and `data\` are created next to the EXE — portable.
 > With the Linux and Windows binaries, `config/` and `data/` (settings, SQLite, GCode store)
 > live next to the program. Copy the whole folder = move the installation.
 **Python directly:**
 ```bash
 pip install -r bridge/requirements.txt
 python bridge/kobrax_moonraker_bridge.py
 ```
 ### 3. Set up the printer
 Open the Web UI: **`http://BRIDGE-IP:7125`**
 On first start the **Printers tab** shows *"+ Add printer"* — just enter the printer's IP
 address, the rest (username, password, device ID) is fetched from the printer and decrypted
 automatically. Done.
 > More than one printer? Just click *"+ Add printer"* again — each gets its own port
 > (7125, 7126, …) and is selectable from the header dropdown.
 ### 4. Connect OrcaSlicer
 Printer → Connection type **Moonraker** → Host: `http://BRIDGE-IP:7125`
 > ⚠️ Connection type must be **Moonraker** (not "Bambu" or "Klipper").
 > Enter the full URL including `http://` and port `:7125` in the host field.

 ## 🔧 Getting credentials manually
 Normally not needed — *"+ Add printer"* does this automatically. If you do need it:
 ```bash
-# 1. Bridge starten
+fetch_credentials --ip 192.168.x.x --write-config
 ./start.sh
 ```
 Fetches the credentials directly from the printer via HTTP and writes them to `config/config.ini`.
 Only the printer IP is required, no slicer.
-`start.sh` baut das Docker-Image automatisch beim ersten Aufruf und startet die Bridge.
+Alternatively (if the IP is unknown): open AnycubicSlicerNext, connect the printer, then run
 `extract_credentials` → outputs username, password, device ID and the printer IP.
-```
+> **Downloads:** [Releases](https://gitea.it-drui.de/viewit/KX-Bridge-Release/releases) → `fetch_credentials` / `extract_credentials` (Linux & Windows)
 # 2. Web-UI öffnen: http://BRIDGE-IP:7125
 #    → Einstellungen (⚙) öffnen sich automatisch beim ersten Start
 #    → Zugangsdaten eintragen (→ siehe Credentials extrahieren)
 # 3. In OrcaSlicer: Drucker → "Moonraker" → http://BRIDGE-IP:7125
 ```
 Logs prüfen:
 ```bash
 docker-compose logs -f
 ```
 Stoppen:
 ```bash
 docker-compose down
 ```

-## Web-UI
+**If KX-Bridge helps you, the project appreciates your support:**
-Die Bridge stellt unter `http://BRIDGE-HOST:7125` eine Web-Oberfläche bereit:
+[![Ko-fi](https://ko-fi.com/img/githubbutton_sm.svg)](https://ko-fi.com/viewitde)
-| Bereich | Funktion |
+</div>
 |---------|----------|
 | Dashboard | Druckerstatus, Fortschritt, Temperaturübersicht |
 | Temperaturen | Nozzle und Bett direkt setzen |
 | Achsen | X/Y/Z-Bewegung, Motorfreigabe |
 | Druckgeschwindigkeit | Leise / Normal / Sport |
 | Lüfter / Licht | Lüfterdrehzahl und Drucklicht |
 | AMS | Filament einziehen / ausziehen |
 | Kamera | Live-Vorschau (falls Drucker unterstützt) |
 | ⚙ Einstellungen | MQTT-Zugangsdaten, Poll-Intervall, Self-Update |
 ### Self-Update
 Über das ⚙-Menü in der Web-UI kann die Bridge auf neue Versionen prüfen und sich selbst aktualisieren — ohne Neuinstallation. Nach dem Download startet die Bridge automatisch mit der neuen Version neu.
 ---
 ## bridge.sh (Linux Service-Manager)
 ```bash
 ./bridge.sh start    # Bridge im Hintergrund starten
 ./bridge.sh stop     # Bridge beenden
 ./bridge.sh restart  # Neustarten
 ./bridge.sh status   # Status und Port prüfen
 ./bridge.sh log 50   # Letzte 50 Log-Zeilen
 ```
 ---
 ## Druckerzustände
 Die Bridge übersetzt die internen Kobra-Zustände in Moonraker-kompatible Zustände:
 | Kobra-Zustand | Bedeutung |
 |---------------|-----------|
 | free | Bereit |
 | printing / busy | Druckt |
 | pausing / paused | Pausiert |
 | resuming / resumed | Wird fortgesetzt |
 | stopping / stoped | Wird gestoppt |
 | finished | Abgeschlossen |
 | canceled | Abgebrochen |
 | failed | Fehler |
 ---
 ## Fehlerbehebung
 **Port 7125 bereits belegt:**
 ```bash
 ./bridge.sh stop    # oder: fuser -k 7125/tcp
 ./bridge.sh start
 ```
 **Credentials ungültig / Verbindung abgelehnt:**
 - AnycubicSlicerNext starten, mit Drucker verbinden, `extract_credentials` erneut ausführen
 - Falls das Ergebnis unsicher wirkt: `extract_credentials --verbose` zeigt alle Kandidaten an
 - Den richtigen Kandidaten manuell in `.env` eintragen und Bridge neu starten
 **Temperaturänderungen werden ignoriert:**
 - Während eines laufenden Drucks werden Temperaturänderungen über einen separaten Kanal gesendet — das ist normal und wird von der Bridge automatisch erkannt.
 **Docker: Permission denied:**
 ```bash
 sudo usermod -aG docker $USER
 # Neu einloggen
 ```
 **Docker: .env nicht gefunden:**
 ```bash
 # .env muss im gleichen Verzeichnis wie docker-compose.yml liegen

 ## Sicherheitshinweise
 - Die Bridge bindet standardmäßig auf `0.0.0.0:7125` — nur im lokalen Netzwerk nutzen
 - `.env` enthält Drucker-Credentials — nicht öffentlich teilen
 - Die Credentials sind druckerspezifisch und haben keinen Zugang zu Anycubic-Cloud-Diensten
