“A couple of months ago, there was a CNC challenge here at instructables, while checking out the entries of that contest, I saw some pretty cool engraving machines and I thought: “Why shouldn’t I make my own?”. And so I did, but I didn’t want to make someone else’s project, I wanted to make my own. And so my story began… :) 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.”
