..... where to start and yet cover everything? I built a new PC to run my small CNC. I'm using WinXP x32 with Service pack 1. I'm using an add-in parallel port card that's putting out 5 volts, as required by my Gecko 540, and I'm using the same parallel printer cable that I used before. The Gecko has a green light in back, and all cables/wires are secure. I've tried using a copy of the XML I used when the machine was running with the old PC, and I also tried the 540.xml file made available from Gecko (which, they say, should be able to at least move the Axis's). Neither one of them work. I've also run the Driver Test with Mach3, and that didn't help. I do have holding power coming from the Gecko, but that's all.

Any thoughts on what the issue might be? In advance, I sure appreciate any assistance or ideas.
