Where did you get it?
It's the exact one in that link I posted earlier.
Did you install such a driver?
Yes
You need to install the UC100 plugin in Machs plugin folder and select the UC100 as the active motion controller, have you done so?
The plugin is there because like I said I'm able to access the plugin window in Mach 3 Loader. It also pushed new firmware to the motion controller.
You report the UC100 operating correctly but what breakout board are you using? Can you get the EStop input to stop Mach?
This I'm not sure as I didn't install a new one. I was more or less pointed at this machine and told to get it working again with 0 bachground knowledge about it.[/quote]

Unfortunately, I'm very ignorant about the operation of this machine which makes it hard for me to accurately judge what correct operation looks like. I've had the actual operator trying to do what he would normally do with it in the shop and he's the one who reported the problem. When you go into the UC100 plugin window, the controller is usually in a state of "Estop" and when you hit Reset it will switch to "Idle" but that's all I've been able to get it to do.
