does anyone else’s aux feeder sound like crap? make a beeerrrrrrttt noise every time it feeds additional filament. I’ve taken it apart and everything looks fine. any help would be great!
I don’t have a Max so I can’t comment on how it sounds. The aux feeder uses a TMC2209 motor driver in UART mode.

There are MANY ways to tune the motor for quiet operation. ONE example is:
Or if you prefer you can manually set the parameters.
Motor specifications (90% sure based on motor dimensions measured from Sovol’s .step model of the aux feeder):
its sounds like a duck quacking every time it feeds . when there is no filament in it and you activate it its much less noisy but sounds like a duck quacking every 10 seconds
Mine sounds terrible, too. It’s extremely loud.
