I recently tried hooking up my Stepper Motor (http://www.pololu.com/catalog/product/1477) to my driver (http://www.pololu.com/catalog/product/2128/pictures) and I haven’t been able to get it to move.
I’ve connected it via this diagram:
Using the 5v output form the Due (powered via USB) and giving the driver a 12V power supply. Just using the built in stepper library examples I haven’t had any success, below is a picture of my setup.
I’ve tried powering the Due with the power supply, I’ve tried swapping the dir/step pins, and I’ve measured the voltage the driver is getting, confirmed for 5v and 12v for the VDD and VMOT respectively. However, I have measured that my power supply isn’t sending any current to the driver (it sends current to the arduino just fine when hooked up).
Any advice would be really appreciated, I’ve been stuck here for a few days now.
