Hi everyone.
I'm looking for a controller for NEMA17 stepper motor that I could program itself without the need for an external micro controller.
Goal is dead simple : it would take two input signal, one would make the motor do a half-turn clockwise, the other would make it do a half-turn anticlockwise.
I'm seen a couple of 'programmable controller' on Ebay (did I mention I'm cheap?) but I'm not sure to which extend those are programmable.
I could do that with an arduino easily but I'm looking forward to save time and part count for my build.
Thanks in advance.
