I had a really frustrating day yesterday!

I wired up the joysticks and buttons to the HID controller and then fired her up for a test. Everything worked as expected except the LCD screen, then I realized I hadn't installed the plugin for Mach3. I copied the plugin over from my main PC and fired up Mach3, only to be greeted by an nice error "Plugin Defective'.

I spent the rest of the day troubleshooting this without success. It's strange that the plugin works fine on my main PC which is Windows 7 64bit, but doesn't like XP, normally it's the other way round.

I have narrowed it down to the USB code but I am not sure where to go from here. One option is to try Windows 7 on the CNC PC, I always thought that it was a no go with Mach3, but apparently 32bit should work, so I might try that today. Fortunately I have a spare HD so I can keep the XP install intact while I test.
