hey, maybe I have some mistake in my thoughts. I want to move my robot but he doesn`t move.

Do you have your stepper driver plugged into position 2 (a.k.a "B")? FabScan Arduino Shield - Media Computing Group - RWTH Aachen University Headed by Prof. Dr. Jan Borchers, we work in Media Computing and Human-Computer Interaction (HCI). Grounded in Computer Science, we develop and s…

Are these pulses driving full steps? 500 steps per second should drive the motor at 150 rpm. This seems pretty fast from starting from a stand still. Steppers can't start at their top speed. They need to be accelerated up to speed. Have you tried larger delays between pulses?

I assume that you are to provide power to the stepper drivers somewhere on this board. Do you have power source for the stepper hooked up?
