Weird noise coming from Y axis stepper motor
Hi everyone, my cr6-se was printing flawlessly so far (this is my third printer) and recently i got two issues :
- false positive filament runout detection (randomly but frequently)
- some weird noise coming from y stepper motor i think, like vibration or maybe electrical noise i don't know (or motor ball bearing?). It's not permanent, it seems to be more present on diagonal fast moves.
I tried to play with eccentric nuts, no effect. Decreasing the printing speed seems to help a bit but not that much (i'm printing at reasonable speed)
Might it be a faulty stepper motor ?
Hope someone can help me to figure this out
