Question, I built a 5x4 plasma table and am using Mach3 and a PoLabs plasmasens THC. Everything is hooked up and working but I cant figure out what Post to use on Sheetcam. I do not have a floating head and it seems like all the THC post processors also include floating heads. So after a few cuts of a project my Z axis is starting really high up and the THC doesnt have time to get it down before the cuts start. At the end of the cut the Z axis is much higher than what it says on Mach3. I edited the switchoffset to 0 but it is still doing it. I ran the program line by line and it seems like the G92 z0.0 is making my plasma head go up. I dont have any limit switches or probes on the z axis. When I use Mach3 Plasma without THC it works fine. Any help would be great. Thanks
