@Leonardo Nice example! is that Keyfob laser cut and engraved or CNC’ed?
It looks like 2mm acrylic.
I am thinking of creating a few small curve rulers with engraved logo.
Is ther or not, if so, we need a system to change bits under function.
V carve text, and shift to a ball bit to do some round craving, so do one, go up in Z, hold pause, to shift bit
and do next carve, or something like that 
It would also require resetting the Z origin because the next bit probably doesn’t cut at the same absolute Z height as the previous one. I created a control in Octoprint to move the head to the X,Y origin so that I can set the new origin after adjusting only the Z height. I need that capability when milling PCBs in order for the holes to be drilled in the correct locations after the etching stage.

CNC Project：Maze！ Took about 43hours to carve. Gcode was generated by Fusion 360. 3 mm diameter steel ball～
