Building a bigger, better laser engraver

[Bart] built a giant laser etcher from scratch. One of his first test engravings included the Hackaday skull-and-wrenches on a polished granite floor tile (we love it when people do that). He used an XMOS controller and Mach3 CNC software to handle the device. With just two axes to worry about this seem like an easy project. The difficult bit is controlling, cooling, and focusing the laser. Oh, and if you screw up, you could be blinded, burned or horribly maimed. But if you start from the beginning you’ll see that [Bart] knows what he’s doing.








me want one!
