Sometimes you just gotta sit down and hack something together. Forget the CAD and the cool software toys; just hammer away until you have something working. That’s how [bobricus] ended up with this cute little laser engraver anyway.
For under $300 US of parts and a few nights working in his pajamas, the aptly named, pajama micro laser engraver is a pretty nice little machine for its class. Not having the space for a full size machine and not necessarily needing its capabilities he aimed to produce something compact.
The frame is aluminium extrusion, the movement is core-XY on linear rails, and it appears to just be a grbl board with a Chinese laser module on it. He took a bit of care to make the frame a cube which allows him to easily vent the fumes from the little unit. There’s even a small air pump to blow the off-gas from the cutting away from the laser.
All in all a nice little hack useful for all sorts of things from solder masks to cutting wood veneers. You can see it zipping around in the video after the break.
