You do NOT want to use this command! This will re-home the Z axis of the machine at it’s current location. This will cause you a LOT of issues as the machine will now think that the top of Z travel is wherever the Z currently is.
What you actually want to do is set your “work offset” for Z at that position (more commonly called your “z zero”)
You can do that with this command:
G92 Z0
This command says “set my Z zero right here, and make it 0”
If you did G92 Z1 you’re saying “I am 1” above the material right here"
