While at MIT last week, I met Jonathan Ward, who's working in the Machines That Make (MTM) group on an open source, low-cost CNC mill made from 26 parts on a ShopBot, called the MTM A-Z. You can download the necessary files (including bill of materials) to make your own! Check out the video above for an overview of the machine. The MTM group has this awesome idea of a fablab 2.0, where all of the big machines will have been made by other machines, reducing commercial overhead and increasing overall awesomeness.
