Early untested Prototype for a 12mm ballscrew Z-Axis for the MPCNC. A ballscrew has less play and should improve the tolerances of your MPCNC.
It's designed for the Burly "F" (EU 25mm) Version.
In theory it should work, but I haven't tested it, yet. Due to a lack of time I provide these files before I tested them. Please share your results if you print and test this design.

Please note that you will need an additional bearing 30/8 for proper ballscew mounting.
Use recommended print settings from the MPCNC
