I am having problems wiring my arduino uno grbl 1.1 and proms sd. It will only run in one direction… I have only tried in test mode, I am trying to figure this out on my own but I think I need some help anybody done this before??
each stepper driver needs to have 2 pins connected, the step/pulse pin, and the direction pin if it only goes one direction, that may be because the direction pin is not connected correctly?
Thanks for the reply I have figured it out it was a ground issue it wanted to go in both directions but it would hardly move going down
