John, you and the others all sound like you have a pretty good handle on the possible causes of your problem. I did want to mention that if there is an open (bad connection) on one of the legs of a stepper motor, you’ll get very erratic behavior, including random starting, stopping, and reversing directions.

Good luck – hope you find a solution soon!
