Nice work. Does your software generate the drill code without the g81 commands? Might have to look into that…for drilling. I’ve milled in the past, not on mpcnc, and got good results once in a while. The laser method has never failed me though and no bits to buy or burrs to clean up. Muriatic acid and peroxide etchant is very fast and effective. There’s a free software called pcb2gcode that does auto leveling but only supports mach3 and linuxcnc probing gcode. I think grbl might work to since it supports straight probing gcode as well but I’m only guessing.
