It took me a while to learn the in's and out's of step and direction signals as well as figuring out just how the old Microkinetics OptiStep Plus 8 bit ISA card worked (DOS Based), but I am pleased to say, I did it. I now have Mach3 software controlling my Torchmate I using the Microkinetics SuperDrive Multi-Axis Power Driver. The key was changing where the DM4050 stepper motor driver cards received their 5 volt reference signal. In the next day or so I will add a couple of pictures along with a detailed description of what I changed to make it all work together.
