Just installed a UC100 and a laptop running Windows 7 64Bit on my router to replace an old Dell with a parallel port. Everything went smoothly until I tried to home. I have a dual motor X gantry and it will not home. The Y and Z home with no problem.

I can jog the X when I first connect with the Mach software, but once I home (only the Y and Z move), I try to jog the X and only one motor goes. I reset the software and I can jog the X again.

If I reconnect the old PC with Parallel cable, it homes and jogs just fine. That points to something with the UC100. I'm not sure what else to do...any suggestions?
