  • You can edit the Z heights or change the filament types as needed or add more filaments to the list.

  • You can look at the g-code and see the offset added for the plate type and filament type selected.

PETG-CF Multi Z Offset Setting @ .05
Multi Z

ASA Multi Z Offset Setting @ .01
ASA Z

PLA Z Setting @ 0
PLA Z

Let me know how it works out for you.

Happy 3D Printing :smiley:

Great, I had the same idea as you.
In particular I would like to set a lower Z offset when printing PetG on carbon effect type plates. For more grip on the surface. PLA remains well attached, PetG does not.

I want to make sure I understand this.
So adding this to my start G-code will adjust the z offset that the machine auto figures when it does the mesh? Or does this tell the machine exactly what the z offset should be according to the Material Type and Plate?
