Hi, what is the minimum and maximum delay values?

[frostybeard]

It depends on your motor. I have some average stepper motor and tried different values. Bigger motors will need larger delays, I suspect. What I came up with that worked, I put in the example. With too small delays, the motor made strange noises and didn't step smoothly. When you are microstepping, you can use smaller delay values because the motor is not moving very much between steps.
