This is an Instructables on how I Remixed my old CNC Laser engraver and made a Stable version of an Arduino based Laser CNC engraver and thin paper cutter using old DVD drives and using 250mW laser.
Old Version of My CNC :https://www.instructables.com/id/Mini-CNC-Laser-Wood-Engraver-and-Paper-Cutter/
Old version was not much stable and had some wobble due to uneven parts, so I decided to make a stable version of it using 3D printed parts. Which gave me excellent results in laser engraving even in very tiny details, this machine is cable of doing the work well. You can see the details in the eye of the engraved picture.
Playing area is 40mm x 40mm max.
