Tried both Uno and Mega...currently Mega Connected, Nema 23 425 oz/in , Sutia M542 driver - 48 volt in, A+-red, A- Blue, B+ - green, B- black, Pul- bridged to Dir - bridged to Gnd
Pul+ to Pin 12, Dir+ to Pin13.....no Enable connection.
I have checked everything numerous times, I have looked at code and to me it looks ok...nothing jumps out at me...but really I haven't a clue,tho I wonder why Cons Int is used and others seem to use Pinmode....just an observation trying to get this sorted.
LCD and Keypad working great.
