Firmware LED Status Introduction​

  • Filament runout: Red flashing
  • Filament loading: Blue flashing (higher loading speed, higher flash frequency)
  • Filament unloading: Green flashing (same as above)
  • Filament present but no loading/unloading: Orange breathing light

Klipper, Filament Runout and Clog Reference Configuration​

Caution

In the clog detection configuration, detection_length: 2.0

2.0mm is the minimum detection length required for this smart filament detection module to function properly. If you encounter false triggering issues, try increasing the detection length by 1 mm until the problem is resolved.
