Both the GCODE-Reference and
give a list of all the parameters available in PlanetCNC.
But both locations are completely missing even rudimental documentation e.g. just a few words of description and the units.
Afaik the same holds true for the PlanetCNC web page.
I can't believe that there exists absolutely no documention where a user can learn about the specification of those parameters.

Can someone help me out here?
