Firmware LED Status Introduction​

  • Filament runout: Red strobe flash
  • Filament loading: Blue blinking (the faster the feed speed, the higher the blink frequency)
  • Filament unloading: Green blinking (same as above)
  • Filament present but no loading/unloading: Orange breathing light

Klipper, Runout and Clog Reference Configuration​

Caution

In the clog detection configuration, detection_length: 2.0

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