So I know that mach4 needs to get some signal to do a touch off. I think this should fix everything except maybe the long cuts around the perimeter of a large part. I figure that the way to compensate for this is to have the torch touch off on the metal each time before starting a new cut. This THC brought a lot of improvement to my cutting but it tends to drift too far one way or the other. Jack Benny had a sitcom back when radio was king and he was very tight (for younger readers). I am the Jack Benny sort of cheap so I bought a PromaSD THC. I started off thinking I could get by without a THC but soon found out the warping would not allow that. When the torch is off the Proma just passes the mach4 signal to the stepper controller.

When the torch is on the Proma takes total control of the Z axis and mach4 has no idea of the torch height as it gets no feedback from the Proma. The Proma gets the Z signal from mach4 and outputs to the stepper controller. Old geezer builds his first cnc project a plasma table. I will describe my situation so you guys will know where I am at and where I want to go. That is a lot to include in a post subject for sure.
