Question #: 11167

Question: Have checked stepper motor wires dozens of times and they are wired like diagram says. Stepper motors will not turn under power. I am using laser control option. What should I do?

Current Solution

This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.
