The DSPMC breakout board matches the Mach3 pin#s. I only have 8 outputs on the board, 1-6 are used for enable, 0 for digit trig, and that leaves me with output 1 to use for spindle cw ( I do need a ccw as well) As I said, If I change It to 1 and not 5 in the spindle setup box, It works until I turn off.
