# KX-Bridge
|
||
|
||
Connects the Anycubic Kobra X to OrcaSlicer – no Klipper, no Raspberry Pi required.
|
||
|
||
KX-Bridge runs on your PC or NAS and provides a Moonraker-compatible interface so OrcaSlicer can control the printer directly: print start, temperatures, progress, pause/resume/cancel, AMS filament changes, print speed, and more.
|
||
|
||
**Version:** 0.9.1-beta4
|

|
||
## Requirements
|
||
|
||
- Anycubic Kobra X in LAN mode (printer must be reachable via LAN, not only through Anycubic Cloud)
|
||
- PC, NAS, or server on the same network (Windows or Linux)
|
||
- Docker or Python 3.9+
|
||
- Printer MQTT credentials → [Step 1](#step-1-extract-credentials)
|
||
|
||

|
||
|
||
## Quick start
|
||
|
||
### Step 1: Extract credentials
|
||
|
||
The bridge needs printer-specific MQTT credentials.
|
||
|
||
> **Important:** The printer must be in LAN mode. The credentials can only be extracted when the printer is reachable directly over LAN (not solely through Anycubic Cloud).
|
||
|
||
Start AnycubicSlicerNext and connect to the printer (wait until the printer status is shown), then:
|
||
|
||
**Windows:**
|
||
```
|
||
extract_credentials.exe --write-env
|
||
```
|
||
|
||
**Linux:**
|
||
```bash
|
||
chmod +x extract_credentials
|
||
./extract_credentials --write-env
|
||
```
|
||
|
||
The credentials are saved automatically to `.env`.
|
||
|
||
> If the result looks uncertain: `--verbose` shows all found candidates. Enter the correct value manually in `.env`.
|
||
|
||
---
|
||
|
||
### Step 2: Check configuration
|
||
|
||
```bash
|
||
cp .env.example .env
|
||
# Open .env and verify the values
|
||
```
|
||
|
||
---
|
||
|
||
### Step 3: Start the bridge
|
||
|
||
**Option A – Docker (recommended):**
|
||
```bash
|
||
docker compose up -d
|
||
```
|
||
Runs in the background and restarts automatically after a system reboot.
|
||
|
||
**Option B – Linux binary:**
|
||
```bash
|
||
chmod +x kx-bridge
|
||
./kx-bridge
|
||
# Or with the service manager:
|
||
./bridge.sh start
|
||
```
|
||
|
||
**Option C – Python directly:**
|
||
```bash
|
||
pip install aiohttp
|
||
python kobrax_moonraker_bridge.py
|
||
```
|
||
|
||
---
|
||
|
||
### Step 4: Install OrcaSlicer profile
|
||
|
||
1. Import `kobra_x_orcaslicer_preset.zip` into OrcaSlicer:
|
||
File → Import → Import Configs → select ZIP
|
||
2. Select Anycubic Kobra X as your printer
|
||
|
||
---
|
||
|
||
### Step 5: Connect OrcaSlicer
|
||
|
||
1. Open printer settings
|
||
2. Connection type: **Moonraker**
|
||
3. Host: `http://BRIDGE-PC-IP:7125`
|
||
4. Click "Test" — a success message confirms the connection
|
||
|

|
||
|
||
## Web UI
|
||
|
||
The bridge serves a web interface at `http://BRIDGE-IP: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 the 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 – Service manager (Linux)
|
||
|
||
```bash
|
||
./bridge.sh start # Start in background
|
||
./bridge.sh stop # Stop
|
||
./bridge.sh restart # Restart
|
||
./bridge.sh status # Show status
|
||
./bridge.sh log 50 # Show last 50 log lines
|
||
```
|
||
|
||
---
|
||
|
||
## Docker – Useful commands
|
||
|
||
```bash
|
||
docker compose up -d # Start
|
||
docker compose down # Stop
|
||
docker compose logs -f # Follow logs
|
||
docker compose pull && docker compose up -d # Update
|
||
```
|
||
|
||
---
|
||
|
||
## Troubleshooting
|
||
|
||
**Port 7125 already in use:**
|
||
```bash
|
||
./bridge.sh stop
|
||
./bridge.sh start
|
||
```
|
||
|
||
**OrcaSlicer connection test fails:**
|
||
- Check firewall: port 7125 must be reachable
|
||
- Check bridge log: `./bridge.sh log` or `docker compose logs`
|
||
- Is the printer IP in `.env` correct?
|
||
|
||
**Credentials rejected:**
|
||
- Start AnycubicSlicerNext and connect to the printer
|
||
- Run `extract_credentials --verbose` and check all candidates
|
||
- Enter the correct value manually in `.env`, then 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, then try again
|
||
```
|
||
|

|
||
|
||
## Configuration reference (.env)
|
||
|
||
| Parameter | Description | Example |
|
||
|-----------|-------------|---------|
|
||
| `PRINTER_IP` | Printer IP address | `192.168.1.100` |
|
||
| `MQTT_PORT` | MQTT port (do not change) | `9883` |
|
||
| `MQTT_USERNAME` | Username (starts with "user") | `userXXXXXXXXXX` |
|
||
| `MQTT_PASSWORD` | Password (~15 characters) | `***` |
|
||
| `DEVICE_ID` | Device ID (32 hex characters) | `xxxxxxxx...` |
|
||
| `MODE_ID` | Model ID (Kobra X default) | `20030` |
|
||
|

|
||
|
||
## 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
|
||
- All credentials are processed locally only — nothing is sent to external servers
|

This project is intended for private use and to enable interoperability between the Anycubic Kobra X and free software (OrcaSlicer).

`extract_credentials` only reads the memory of the AnycubicSlicerNext process running on your own PC. No data is transmitted or stored anywhere other than the local `.env` file.
