LED laser engraver
thingiverse
Self-made laser engraver. 2.5W laser. 8mm rods and linear bearings (what was available). Think it's enough - it's not a mill. Frame made of 25 profile. Nema 17 motors 34. Focus can be adjusted on the laser itself with a lens or by raising it up and down with a screw, like an axis Z. Endstops min/max on all axes. Mana SE controller with added endstops. Adjustable legs. The machine is not big. It's just interesting to build it yourself. Drawn and printed myself. Of course, I got some ideas from somewhere.
