hey all I'm new here and I'm stuck with my machine. I built my own cnc machine. was running a nvum controller with mach3 but kept have problems so was looking around for a new controller and came across this from ukcnc CNC 6-Axis dual Mach3/GRBL Controller. having started with grbl i thought i would give it a try, so got it all wired in but red light on drivers keeps coming on when I try to move the motors, I'm running nema 23 with dm556 drivers i know not the best but its what i have atm. anyways its all wired in right i did try a nema 17 and it was moving a bit at a time so switch back to nema 23 and just red light. anyone have a clue, any here would be greatly appreciated thanks
