MichielD99, a 16 year old Belgian teenage maker build this amazing laser engraver using Arduino UNO, two NEMA-17 stepper motors and stepper motor drivers.

This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use lasers of (a lot) more than 50W. But this laser will do well for us. It can cut through paper and cardboard and it can engrave all kinds of wood. I haven’t tested other materials yet, but I’m sure it can engrave many other materials. l will let you know! It has a large engraving surface of about 500x380mm.
