It currently has 12v power supply but if i need to upgrade I will.
i have 4-wire Nema 17 motors plugged in to the board accordingly:
Red = A+
Blue = A-
Green = B+
Black = B-
I am running windows 7 32-bit version, with a parallel port. that has an I/O range B0D0-B0D7 and B0C0-B0C7
The part holding me back is the pin configuration on Mach3. I have tried the manufacturer configuration and did not work. If anyone has gotten these boards to work any Mach3 configuration files would be greatly appreciated. Any imput would be greatly appreciated. Thank You!
