My router has been working fine with Mach3 for almost a year. Whatever code is sent to the controller now, the Z-axis rises from "0" and continues until it hits the limit switch. The G-code appears to read ok.

Does anyone have a clue what might be causing this? I haven't changed any settings that I'm aware of. I hope this is something really simple that I have missed, as I'm behind with a project that should be finished today. Thanks for any help you can give
