Proma 150 post processor help needed.

I need some help selecting or editing a post processor to work well with my Proma compact 150 THC. I don’t have a floating head machine. I don’t need drill, scriber or backlash. Whenever I use a THC post processor it continually resets my z zero higher and higher. How can I use the THC without the z zero climbing out of range?

Just use the ‘Mach3 plasma’ post. The THC posts are only needed if you have a touch-off switch.

Thanks!
