Hello and good day all. My name is Silas, and I am trying to figure out how to get the correct Z axis compensation for non-conductive surfaces.

I have successfully set-up a touch off system on my Zen-works 7x7 mill using Linux CNC and autoleveller, which is an awesome piece of software btw.

I can easily use it with copper clad or any other conductive surface, however the documentation is too brief on the touch off plate method. I can easily have the autoleveller code touch off using a piece of copper clad and moving it around the non-conductive object to get level readings. My question is how do you go about compensating the height of the material used as the touch off plate throughout the entire GCODE file?

Any help on this matter would be greatly appreciated.

Thanks,
SIlas.
