LED laser engraver

cults3d

Homemade laser engraver. Laser 2.5W. Bearings and linear bearings 8mm (what was available). I think it's enough - it's not a milling machine. Frame made of 25 profile. Motors Nema 17 34. Focus can be adjusted on the laser itself with a lens or by lifting it up and down with a screw, like Z axis. End switches min/max on all axes. Mana SE controller with added end switches. Adjustable legs. The machine is not big. Just interesting to build it. Drawn and printed myself. Of course, I took some ideas somewhere.

Layer 0.2. With supports, where necessary.
