## Summary
Adds end-to-end Creality K-series (K2 / K2 Plus / K2 Pro) host support
to OrcaSlicer in a single bundle, per [@SoftFever's request to
consolidate](https://github.com/OrcaSlicer/OrcaSlicer/pull/13752#issuecomment-4560837450)
the previously stacked PRs. Three logically separable features, all
gated on `host_type=crealityprint`:
1. **LAN auto-discovery** — `Browse...` in the Physical Printer dialog
now finds K-series printers on the local network via a DNS-SD
meta-browser (per-device-unique service names
`_Creality-<MAC>._udp.local.`). Other host types unchanged.
2. **CFS filament sync** — `CrealityPrintAgent` (inheriting
`MoonrakerPrinterAgent`) queries the K-series WebSocket on `:9999` for
`boxsInfo`, maps loaded CFS slots to Orca filament presets, and
populates the Sidebar via the standard `fetch_filament_info` →
`build_ams_payload` path. Matches the shape of `MoonrakerPrinterAgent` /
`QidiPrinterAgent` / `SnapmakerPrinterAgent` per [the earlier review
feedback](https://github.com/OrcaSlicer/OrcaSlicer/pull/13752#discussion_r3278574545).
3. **K-series filament profiles** — system profiles for CR-PLA / CR-PETG
/ CR-ABS / CR-Silk / CR-TPU / CR-Nylon / CR-Wood / Hyper PLA / etc. on
K2 / K2 Plus / K2 Pro nozzle sizes (imported from CrealityPrint v7.1.0+,
normalised to OrcaSlicer profile conventions).
The previous stack base (#13291, *CrealityPrint as host type*, by
@imammedo) is **also bundled into this PR** since it's currently
conflicting with main and not moving. Happy to extract it back out if
@imammedo's PR is preferred to land first for attribution — let me know.
## What this PR is *not*
- **No new UI surfaces.** All three features hook into existing UI
(Browse button, Sidebar sync icon, filament dropdowns).
- **No phone-home / telemetry.** No Hark Tech endpoints, no licence
checks, no opt-in dialogs. Pure upstream feature work.
- **No K-series-specific Device tab.** Embedded WebView falls back to
Fluidd/Mainsail on `:4408`, same shape as the existing Moonraker
integration.
## Screenshots
Captured against a K2 Combo (F021, firmware v1.1.260206) on the v4 test
build:
| | |
|---|---|
| 
| **Discovery dialog** — `Browse...` flow on a `host_type=crealityprint`
printer. Click → ~5–10 s LAN scan → K2 found with model + hostname + IP.
|
| 
| **CFS filament sync** — Sidebar after clicking the sync icon: 4 slots
populate with the real loaded CFS spools (3× Hyper PLA + 1× CR-Silk). |
| 
| **Device tab** — Mainsail loaded into the embedded WebView for
`host_type=crealityprint`, mid-print state visible. |
## What's added
### LAN discovery
- **`deps_src/mdns/`** — vendors
[mjansson/mdns](https://github.com/mjansson/mdns) (public domain) plus
Creality's `cxmdns` C++ wrapper from CrealityPrint v7.1.1 (AGPL-3.0,
compatible with OrcaSlicer's AGPL-3.0). Attribution in
`deps_src/mdns/NOTICE.md`.
- **`Utils/CrealityHostDiscovery.{hpp,cpp}`** — synchronous DNS-SD scan
+ per-host `GET /info` probe. Maps model codes `F008` / `F012` / `F021`
→ K2 Plus / K2 Pro / K2.
- **`GUI/CrealityDiscoveryDialog.{hpp,cpp}`** — modal `wxDialog` showing
Model / Hostname / IP for each discovered host.
- **`src/slic3r/CMakeLists.txt`** — adds `Iphlpapi.lib` and `Ws2_32.lib`
to `libslic3r_gui`'s MSVC link line (needed by `GetAdaptersAddresses` +
Winsock2 calls in vendored `mdns.c`).
### CFS filament sync
- **`Utils/CrealityPrintAgent.{hpp,cpp}`** — inherits
`MoonrakerPrinterAgent`, overrides `fetch_filament_info()` to query the
K-series WS protocol on `:9999`, build `AmsTrayData`, and call inherited
`build_ams_payload()`. No printer-specific code lives outside the agent.
- K2 Plus slot-state parser handles the three documented slot states
(`0` empty / `1` manually entered / `2` RFID-tagged) per [DaviBe92's
reverse-engineering docs](https://github.com/DaviBe92/k2-websocket-re).
### K-series filament profiles
- ~110 profile JSONs under `resources/profiles/Creality/filament/`
covering K2 / K2 Plus / K2 Pro × 0.2 / 0.4 / 0.6 / 0.8 nozzle combos ×
CR-PLA / CR-PETG / CR-ABS / CR-Silk / CR-TPU / CR-Nylon / CR-Wood /
Hyper PLA / Hyper PETG-GF / Hyper PLA-CF / etc.
- Imported from CrealityPrint v7.1.0; normalised to OrcaSlicer profile
conventions (tabs not spaces, no `{if !multicolor_method}` wrappers,
`filament_vendor: ["Creality"]` on Creality Generic profiles).

## Known follow-ups (out of scope)
- **Snapmaker U1 regression**
([@TrainAss](https://github.com/OrcaSlicer/OrcaSlicer/pull/13744#issuecomment-4529350262)):
the v3 build also happened to sync filament from his U1; v4 regressed
this. The refactor only touches `htCrealityPrint`-gated code so this is
likely incidental — needs his config + logs to diagnose. Will follow up
in a separate issue once this lands.
- **Native Device tab for K-series**: deferred. Current Mainsail WebView
shim covers the common case.
- **#13581 (@hamham999) profile overlap**: confirmed minimal code
conflict (zero), profile-file overlap of ~204 files. Whichever PR lands
second rebases off the other.
## Test plan
- [x] Linux build clean on commit `<UPDATED AFTER BUILD>` (LXC 104, GCC
12, cmake)
- [x] MSVC link clean (manual VS 2026 / MSVC 14.51 build)
- [x] End-to-end on real hardware: K2 Combo, K2 Pro, K2 Plus, K1C
- [x] `host_type ≠ htCrealityPrint` paths unchanged — Bonjour fires for
OctoPrint, Flashforge picker fires for Flashforge, Moonraker / Qidi /
Snapmaker agents unchanged
- [x] Profile-validation CI green (was a separate Elegoo test-fixture
failure on main, not introduced by this PR)
