I have a chesterman I want to convert to cnc control.i have already bought nema 34 steppers an dq860ma drivers ,but I cant get it to function with the break out board db 25 pin parallel port ,I have since bought another USB 4 axis breakout board. I need help setting up and making alterations to mach3 settings
