The 3D_Printer is upgraded and doesn't have a Laserdiode now`
Mount a 1,5W laser on your 3D printer and your laserengraver is ready to go.
Recently I got an 1.5 laser module. It's one of these typical modules which are offered from popular Chinese or other shops. Mounted on my 3D printer, a nice Laser engraver is ready to use.
