I have a question, does anyone know or can explain what the Material (mm) box and selection in Cut/Layers window for as I can find no reference to this box and selection in the manual online?
I can’t “see” what you mean can you make a screen dump?

I don’t know. Neither in my GRBL nor in my DSP setup do I have this mm setting option. If you move the mouse over this field, does an info pop up?
Which profile are you using?

If you have “Z” axis control turned on for your machine, that field shows up to set the thickness of your material that you are engraving on. There is some information here under “Z Control”
