Hello, I forgot to mention it still vibrates when retracting/feeding without any filament inserted. Only thing that was left to test for me to rule the motor out would be to take the extruder off and try to spin it at the same rate, to see what happens.
I have already taken it apart and I saw no bits of ground filament anywhere.
