I use G28 homing to 0 on a hard origin (aluminum angle) on my MPCNC. However I don’t care for the homing speed of the first touch, feel like I am going to break a tool.
I have tried M220, but that doesnt seem to effect G28s. You cannot specify a F parameter on a g28 either.
Any other way to do this without a FW flash? I know G38 can take feedrate parameter, but that requires FW flash too. For what its worth, im not afraid of a FW flash, I have done it to my 3D printers many times, just lazy I guess.
Alternatively I suppose I could make a dedicated “probe” (steel cylinder) of known diameter to mount in the router. Just adds a tool change.
