Stepper motor vibration/lockup with driver? Answered
I am trying to get a stepper motor to turn using a StepStick driver from Botronicz. I have gotten the driver to work once before, but now it has decided not to work. I have wired my stepper motor (Model STP-42D3018) according to any specs I can find online in a bipolar connection, but when I fire it up the stepper only sits there and vibrates. Or misses steps (depending on voltage). A few other times I had it also where it would step one direction for I think a single step and then step back the other direction. It is really bothering me because I have tried multiple other wiring combinations and have not gotten any of those to work. My current setup is exactly like this (I have checked numerous times). I have also tried changing the vmot supply voltage and current limit, as well as the current limiter pot on the board itself.
If anyone can help it would be greatly appreciated!
