I had a similar issue and it was a bad stepper motor. The bearings on these are just wide open and a bunch of filament dust had worked it’s way into them. Turning the motor shaft by hand you could feel it get tight at certain points in the rotation. I just swapped in a new motor but you may be able to clean it out if you want to save the $9.
