# KX-Bridge – Anycubic Kobra X
**Version:** 0.9.7
Control your **Anycubic Kobra X** with OrcaSlicer — no Klipper, no Raspberry Pi.
KX-Bridge is a Moonraker-compatible bridge that communicates directly with the printer.
---
## Quick Start in 3 Steps
### Step 1 – Prepare the printer
Enable LAN mode on the Kobra X:
**Printer display → Settings → Enable LAN mode**
### Step 2 – Get credentials
The MQTT credentials are printer-specific. Here's how to get them:
1. Open **AnycubicSlicerNext** and connect the printer (wait until status is shown)
2. Run **`extract_credentials.exe`** (Windows) or **`extract_credentials`** (Linux) — outputs Username, Password, Device ID and printer IP
3. Note / copy the values
> **Download:** [gitea.it-drui.de/viewit/KX-Bridge-Release/releases](https://gitea.it-drui.de/viewit/KX-Bridge-Release/releases) → `extract_credentials.exe` (Windows) / `extract_credentials` (Linux) in the release assets
### Step 3 – Start the bridge
```bash
./start.sh
```
The script builds the Docker image automatically on first run.
**Open Web-UI:** `http://BRIDGE-IP:7125`
→ The ⚙ menu opens automatically on first start
→ Enter credentials from Step 2 → **Save & Restart**
**Connect OrcaSlicer:**
Printer → Connection type **Moonraker** → Host: `http://BRIDGE-IP:7125`
> **Important:** Connection type must be **Moonraker** (not "Bambu" or "Klipper").
> Enter the full URL including `http://` and port `:7125` in the host field.

## ⚠️ Upgrading from 0.9.1 or earlier
Starting with **0.9.2**, KX-Bridge stores settings in `config/config.ini` instead of `.env`.
**Migration is automatic** — no manual action required:
- On first start after upgrade, the bridge reads your existing `.env` and creates `config/config.ini` automatically
- Settings now survive `docker-compose restart` and future updates
- The `.env` file stays mounted read-only as a migration source — you can keep it in place
- If you want to create a `config.ini` manually: copy `config/config.ini.example`

## Alternatives to Docker
**Linux binary** (no Docker needed):
```bash
chmod +x kx-bridge
./kx-bridge
```
**Python directly:**
```bash
pip install aiohttp
python bridge/kobrax_moonraker_bridge.py
```
Web-UI available at `http://localhost:7125` — the ⚙ menu guides through initial setup.
---
## Useful commands
```bash
# Show logs
docker-compose logs -f
# Stop bridge
docker-compose down
# Restart bridge (after update)
./start.sh
```
---
## Troubleshooting
**"Wrong MQTT credentials"** on start:
- Restart AnycubicSlicerNext, reconnect the printer, run `extract_credentials` again
- Enter only the IP address, no port (✗ `192.168.1.102:9883` → ✓ `192.168.1.102`)
**Printer not found / no LAN mode:**
- On the printer display: Settings → Enable LAN mode
- Printer and bridge must be on the same network
**Docker: Permission denied:**
```bash
sudo usermod -aG docker $USER # then log out and back in
```
---
## Security
- The bridge is accessible on the local network at `http://:7125` — do not expose to the internet
- `config/config.ini` contains printer credentials — do not share publicly
- Credentials do not grant access to Anycubic cloud services
