G2 board: how to set the nozzle offset (M212 thing) [SOLVED]

[Barafu Albino]

Subj. How to set the Z difference between the probe and the nozzle? G2 does not support M212 and fiddling with G5X commands seems to break tram calculations. Who has it working, please explain me.

Cool! TinyG includes workspace support, glad to see they carried it along instead of the z offset kludge.

Workspaces, you say? If you care, Google and the reference section of LinuxCNC.com are a good starting point. Workspaces (more than one at a time are possible) are often used to set zero at the top of the workpiece, the chunk of whatever you're about to attack with spinny sharp cutting tools. Gosh, we're getting closer to real g code

I know about this stuff. The problem was that I tried to use G28.3 or G10 or G92 instead, and while all of them did shift coordinates system, all of them also cancelled out the tram compensation. The M100.1 ({g55z:-0.8}); G55 is the only working way for now that I am aware of.
