Gcode modification - M555
Hi,
I want to print directly on a small polymer (50mm x 50mm) that would be taped on the steel sheet. I'm trying to find a way to tell the printer that this small polymer square is the new Z reference. I thought about modifying the initial probe that the printer does while the nozzle is at 175 degrees, before the purge, so that it probes points where the print will be (instead of a little bit farther from it).
From what I understand, I have to modify the M555 line in the Start G-code. I tried to modify the numbers there but nothing seems to change during the probing.
Does anyone have experience with this?
Thanks!!
Vincent
