PROXXON Micromot 50 Holder

This is a holder for the PROXXON micromot 50, to attach it to the Mendel90 x-carriage instead of the extruder. This way you can convert your Mendel90 into a CNC drilling and milling machine. I'm using this for drilling PCBs.

What I'm still missing is something to mount the PCB reliable. My provisorily test succeeded, though ;-)

Howto: Unlike 3d-printing I don't use the endstops. I manually drive the drill to a reference point using pronterface. Then I set the origin using "G92 X0 Y0 Z3", Z
