With MACH3 you can assign any pin you want. I have X on pins 2,3 just like I have for my Electronic Lead Screw kit. Pin 10, I think,is the only one that should be ESTOP because that's what most BoBs use. The Linux CNC machine I'm putting together also has X on 2,3 and the BeagleBone Black with MachineKit also has X on pins 2,3.
So I'd rewire it. And still waiting for pictures or did I miss an email?
