Manually set Z0
I want to know, is there a way to set manually Z0? I tried with G92 Z0 but nothing happen. Making tests with different configurations of my extruder, it is very hard to set every time when I make some changes, the correct high for Z probe. I want to use the check of Z0 using the sheet of paper, and tell to Repetier: "That is my Z0".
Is that possible?
