Hey people,

We are on our way to finish a CNC plasma cutter with a boildermaker.

Mach3 R3.043.066 is used to controll the system and we are using a THC150 for the height control.

When launching the job, the Z axis got a problem: it diving linearly until touching the plate.
On Mach3, when we launch the job we can visulizing the heigh constant, then at the end we observe the Z value decremented at once (but we can see it happens continually while cutting).
Like the Z motor needs to be calibrate or corrected by an offset or something like this.

The fact is it work on manual mode.

Is anybody recognize this issue?
Do you have any idea what's happening there?

Please let me now if you can help me.
cheers.
