I have stumbled across the most peculiar project on a make fare page. This grbl is gcode that is flashed onto an atmega using the bootloader. The parameters are set and the drill can instantaneously work, because of axis parameters called on a terminal import/upload. The video is pretty neat, and the grbl is all about maker projects, because arduino people have initialized. The guys who are the founders are into cnc milling. The milling can be controlled by the arduino, and at best a prototype can be constructed at school so that students can can have fun with a DIY cnc mill. here is a link to the site. grbl
