- check the speed of the signals you are giving it, if they are too fast
- the motor can not mechanically keep up with them and funny things can
- happen. I realize that too fast for a stepper is quite, fast but I had
- a similar problem with running them too fast and if I bumped the stepper,
- or gave it a push, it would start running backwards. Anyways, just a
- thought.
