Auto-Discovery
Bridge automatically discovers Elegoo printers on your network via UDP broadcast on port 3000. Discovered printers appear in the Bridge web UI as suggestions you can add with one click.
Camera Streaming
Elegoo printers with a built-in camera stream video over HTTP. Bridge auto-detects the camera URL:
http://<ip>:3031/videoThe stream is relayed to your PrintHQ dashboard automatically. No additional configuration needed.

Troubleshooting
- Can't connect? Make sure the printer firmware is up to date. Older Elegoo firmware may not support SDCP v3.
- Status shows "Unknown"? The printer may be in a transitional state (preparing, calibrating). Wait for it to reach printing or idle state.
- Temperatures show but no print info? Print info (filename, progress, layers) is only sent when the printer is actively printing, not during idle or preparing states.
- Camera not loading? Verify the camera is connected and port 3031 is accessible. Some Elegoo models may require a firmware update for camera support.
