LiBu Mini Laser Engraver

Description Hi! We proudly present, LiBu, your little burner. This 3D printed structure's objective is to bring an universal option for those who want to build it's own mini laser engraver, using old CD/DVD units scavenged from old computers, using it's stepper plates. The idea is to biuld the machine using the printed parts as a structure, only adding some M3 screws and nuts (only M3 everywhere). The axis are thought to be kind of adjustablein height and width to fit as CD/DVD plate models as possible. The whole thing can be set up with an Arduino Nano, 2 stepper drivers, a 250+ mW laser and a pertinent driver, this will allow you to engrave wood and plastic, and cut paper and foam. The firmware I recommend is Grbl, which is the most standard and open that I know. There are thousands of websites where you can learn how to extract and use the laser from the CD/DVD unit and use it (this project was deeply inspired by them), like: http://www.instructables.com/id/Pocket-laser-engraver/ or http://www.instructables.com/id/Disassembling-a-CDDVD-reader-and-reusing-its-parts/ or http://www.instructables.com/id/Frankenstein-Laser-Engraver/ but there are many many others :) And there also some other sites where you could buy the whole laser unit (diode + driver), like Odic force. There's ebay, alibaba etc. WARNING!!! REMEMBER THAT A LASER MAY SERIOUSLY AND DEFINITIVE HARM YOUR EYES, DO NOT EVEN START THE LASER PARTS IF YOU DIDN'T GOT A GOOD PAIR OF GOOGLES, AND REMEMBER THAT THEY HAVE TO BE SPECIAL FOR YOUR LASER COLOR (WAVELENGTH). BEWARE THE IR LASERS, YOU CANNOT SEE THEM BUT THEY'RE AS HARMFUL AS THE OTHER TYPES.
