Download our manual for the MP1000 off the website. It has some generic setup stuff using our screens and XML's (available off candcncsupport yahoo group). there is more to it than just loading a screen. The first part is to trigger a relay to turn on the torch (output1) using an M03 and M05. A lot of the inputs on the MACH supplied screen are parameters that would normally come from your CAM program. SheetCAM has excellent plasma features and controls lead-ins, offsets, pierce height, pierce delay, cut height, etc.
