-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.+Original machine was custom built by Ron Bean and Tom Gondek at Milwaukee Makerspace. Since it has arrived at The Bodgery it has been rebuilt and modified primarily by Alex Kovell, Tony Roman, and Chris Kaufmann.

-== Software == +===== History =====
- +
- +
-[[http://chilipeppr.com|Chilipeppr]] software requires program in G-Code format, though direct import of SVG files is currently (March 2016) in testing. +
- +
-Use [[http://easel.inventables.com/|Easel from Inventables]] for simple 2D and 2.5D milling. Tutorial to be added here. +
- +
-For full 3D profile milling, [[https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-activate-start-up-or-educational-licensing-for-Fusion-360.html|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. +
- +
-The size of work area is: 24" x 32.5" +
