Hi guys i am VERY new at all of this cnc / g-code stuff.
I bought a locally made plasma table and it does a excellent job running sheetcam and mach3 but when i do a "dry" run ( thc and powermax 45 off ) it will find TOM, go to pierce height (3.8mm), go to cut height (1.5mm) and it will physically be at 1.5mm and then move for the cut all good and nice, BUT all of the pierce`s to follow does not go to 1.5mm cut height but stays right against the plate about 0.2mm away but z axis in mach3 shows +1.5mm. Any help would be highly appreciated.
Here is the g-code for the first and second pierce.

So i managed to fix the problem last night turns out to be the z-axis velocity was way to high changed it from 2000mm/min to 1000 and now it pierce and cut at the exact heights without thc and with thc it keeps it all in the ballpark.
