Why would you assume such a thing.? . . . .Knowing these things I'd think would be much more chance that it uses Mach3.?

So the question should be what control software are you using.?

Pemmot.
If your using Mach3 or 4 then you will need a Plug-in which is written exclusively for the USB controller you have.
