This is a Lego Mindstorms based CNC/Laser Cutter. It has a DC-motor with a drill bit for engraving or a magnifying glass for going out in the sun and cutting paper or thin foam core. It was not design to be a super accurate CNC/Laser Cutter and does not use stepper motors but instead uses mindstorms servo motors. For electronics I used the LEGO MINDSTORMS NXT brick and programmed it in the original software but i plan to to program it in NXC and have it engrave the words LEGO. if you like this project please comment and rate my project , thank you .
