Not sure if it's the same problem as yours, but my step motor would partially retract and then the motor would start "grinding" and I had to manually push the steps back in the rest of the way. I called Thor Customer Service - they shipped out a new motor the same day and I received it less than 24 hours later at no cost (under warranty).
