The MKE HomeBrew CNC Router was given a home at The Bodgery in 2015. The Bodgery acquired a TinyG controller board for it, and the HomeBrew CNC was upgraded to use this USB based controller. It has taken a team of MadCityMakers to get it operational, and we are still working on ironing out all of the wrinkles as of late March 2016.

Use Easel from Inventables http://easel.inventables.com/ for simple 2D and 2.5D milling. Tutorial to be added here.

For full 3D profile milling, Autodesk FUSION 360 is suggested, as it is a CAD and CAM software package which is available to makers on an annual basis free of charge.
