Hey there,

My name is Olivier,
I'm helping a local boilermaker to build his own CNC plasma cutter.

We are using Mach3 R3.043.066 version.
They are really close to make it work correctly (V3 on their way, 2000×3000 mm habitable area).
We are using this device (THC150): https://proma-elektronika.com/product/compact-thc-150/.

When launching the job, the Z axis got a problem: it diving slowly to the iron 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 (eventhough we can see i happens continually while cutting).

Like the Z motor needs to be calibrate or corrected by an offset or something like this.
I may be wrong but I think the problem is between mach3 configuration and/or this device.

Can you help me ?
Is anybody recognize this issue?
Do you have any idea what's happening ?

Please let me now.
Olivier.

anybody?
