Instructions

Precaution : You need an 3 Axis mill and an 60° Mill for that but it should be great upgrade
The spindle is an standard "Kugelumlaufspindel" (if someone knows the propper therm for ballbearingspindle drop me an mail i´ll then update it ;)-
which has an M14 nut this is driven by the Z Axis of the Mill.
The rest setup is standard RAMPS 1.4 and Stepper motors endstops ,

Steps:
1) Mill the baseplate (CUT2d will do the job Deskproto as well )
2) Mill The side Plate (Remark i will do an update to be able to mount the Printhead 180° turned to have the heavvy Stepper towards the inside !)
3) Drill the holes in the sidewalls in propper position
4) Drill the 6mm H7 holes
5.) Mount all for beeing able to mill the 60° Sideguards
Use your actual Z Guard to have an good fit.
(I had to do that 2 Times
To be done
6.) Mount all steppers & test it.
7.) Adjust marlin that it allows dangerous prints ;)-
Happy milling & Printing
