Cnc controller for xr

Hello all. I have been trying to torture my poor xr into doing unnatural acts. With a bit of success. But, as humans tend to be, I am not satisfied quite yet.
I do not really want to go poking around under the hood so if anyone knows what cnc controller the xr uses, I would like that information. even easier would be, can mach3 be used with the xr?
thanks in advance!!
