LiBu Mini Laser Engraver

pinshape

Description \n We're excited to introduce LiBu, your tiny laser engraver! This 3D printed structure is designed to provide a universal solution for those who want to build their own mini laser engraver using old CD/DVD units salvaged from discarded computers and stepper plates. The idea is to assemble the machine using the printed parts as a base, adding only M3 screws and nuts (all M3 throughout) to create a sturdy structure. The axis are adjustable in height and width to accommodate various CD/DVD plate models. To bring your LiBu to life, connect it to an Arduino Nano, 2 stepper drivers, a 250+ mW laser, and a suitable driver. This setup will enable you to engrave wood and plastic, as well as cut paper and foam. We recommend using Grbl firmware, the most standard and open option available. For inspiration and guidance, check out websites like Instructables, where you can find tutorials on extracting and utilizing lasers from CD/DVD units. Some notable examples include http://www.instructables.com/id/Pocket-laser-engraver/, http://www.instructables.com/id/Disassembling-a-CDDVD-reader-and-reusing-its-parts/, and http://www.instructables.com/id/Frankenstein-Laser-Engraver/. Alternatively, you can purchase a pre-assembled laser unit from sources like Odic force or through online marketplaces such as eBay and Alibaba. Important Safety Reminder: Be extremely cautious when working with lasers! They can cause serious and permanent eye damage. Never start the laser parts without proper protective eyewear, specifically designed for your laser's wavelength. Be aware that IR lasers are particularly hazardous, as they're invisible but just as damaging as other types.
