I bought a 5x10 gantry CNC without documentation or support. It runs on Mach 3 on a win 7 PC.  The machine looks identical to an Industrial Craftsman 510 model. I dont have a way to verify that the ports and pins are set up correctly. Is anyone out there running an Industrial Craftsman 510? If yes, would you be willing to share a screen shot of your ports/pins page?
