LiBu Mini Laser Engraver

thingiverse

We're thrilled to introduce LiBu, your compact laser engraver! This innovative 3D printed structure offers a universal solution for those who want to build their own mini laser engraver using salvaged CD/DVD units from old computers and their stepper plates. The idea is to assemble the machine by combining the printed parts with M3 screws and nuts (the only type used throughout). The axes are designed to be adjustable in height and width, accommodating various CD/DVD plate models. With an Arduino Nano, 2 stepper drivers, a high-powered laser, and its corresponding driver, you'll be able to engrave wood and plastic, as well as cut paper and foam. We recommend using Grbl firmware, the most widely used and open-source option available. If you're interested in extracting and utilizing the laser from the CD/DVD unit, we suggest checking out websites like Instructables, which offer a wealth of information on this topic. Some popular examples include: * http://www.instructables.com/id/Pocket-laser-engraver/ * http://www.instructables.com/id/Disassembling-a-CDDVD-reader-and-reusing-its-parts/ * http://www.instructables.com/id/Frankenstein-Laser-Engraver/ Alternatively, you can purchase the laser unit (diode + driver) from online retailers like Odic Force or eBay. **Important Safety Notice:** A laser can cause serious and permanent eye damage. Never start the laser components without proper safety goggles, which must be specifically designed for your laser's wavelength. Be aware that infrared lasers are particularly hazardous, as they are invisible to the naked eye but still pose a significant risk.
