- I've got a 4-phase stepper motor that I'm trying to control, by
- sending it the required sequence of 4-bit patterns (1001, 1010, 0110,
- 0101, repeat), and the motor runs for 2-6 seconds (hundreds of steps)
- and then it gets confused and just starts wiggling.
-
- Has anyone else had this problem?
-
- The motor behaves as it would behave if it had gotten out of
- synchronization with the step commands, but I can't imagine why this
- would suddenly happen after hundreds of successful steps.
-
- Can anyone give me some advice?
-
- Thanks,
- Don Mathis mathis@cs.colorado.edu
