Firmware LED Status Introduction​

  • Filament Runout: Red flashing rapidly.
  • Filament Loading: Blue blinking (blinking frequency increases with loading speed).
  • Filament Unloading: Green blinking (same as above).
  • Filament Present but No Loading/Unloading: Orange breathing light.

Klipper Configuration Reference for Filament Runout and Jam Detection​

Caution

In the jam detection configuration detection_length: 2.0

2.0mm is the minimum detection length required for the smart filament sensor module to function properly. If you encounter false triggers, try increasing the detection length by 1 mm until the issue is resolved.
