Hello!
I have an old Roland Gravograph Unica engraving machine and I would like to rebuild it to use Mach3 software. There is in use three 1.8 Deg DC 0,8A Stepper motors. What controller and breakout board would you recommend? Should I change the old stepper motors to Nema 17? AliExpress sells closed loop stepper motor driver controllers but they are meant to be arduino. I would prefer some other breakout boards what designed for Mach3. Maybe someone can recommend a good 3 axis cnc kit.
Thank You!
