One of my AMS is making a constant drawing-in noise. However, nothing is drawn in. All 4 LEDs are permanently white. All filament spools can be moved and the filaments can be pushed out and into the feeder.
What could this be?
What do you mean? Continuously scratching noise?
In any case, can you check if there is any effect on:
- removing the spools; if so, which spool(s).
- Swap the cable port on the back.
If nothing, it may be relevant to identify the origin of the noise.
