Lego CNC Machine

This is a Lego CNC Machine that I made. It has X, Y, and, Z axis of movement, which means that it can move up and down, right and left, and in and out. It routes the word LEGO into a piece of foam. The motor used for the drill is a motor out of an rc car and it rotates at about 30,000 rpm. The drill bit is not sharpened and is just a lego bushing. The computer system used is Lego Mindstorms NXT 2.0. It took me about 20 hours to build and program and most of the programming was based on trial and error.
