Hi guys, Here I am back in bewilderment land. I am trying to run a stepper motor with a Spark Fun Big Easy stepper motor driver. No problem except no matter what PWM I put in the motor runs at the same speed. About 24 RPM. I checked the PWM and it is doing exactly what the EZ-Bv4 tells it to do but the Big Easy just runs the motor at the same speed. Anybody know what is going on?
