Cloudray 12/18mm FL50.8 & 16mm FL25.4 Laser Head With Air Assist For K40 Laser Engraver Cutter

Works well on my Monport 40W laser using the original lens. Was easy to install and looks much better than the original. In the next version, I would put a line on the outside indicated the position of the lens.

Excellant upgrade for my K40. Fit perfectly. I used my existing 12mm lens, realligned mirror and it works great.

Fit without modification, works well with standard air flow. Would be nice if the mirror tilt could be adjusted, but for the cost it's worth buying.

Well made, no random chips in threads, burrs on holes, etc. Ignore silly comments about having to enlarge the mounting hole, that's user error. The head has 3 threaded parts, be sure you unscrew them all so you understand how to install. Also note it needs an 18mm lens, or 15mm with the included spacer. The standard lens in the K40's is 12mm, too small for the head, and they're usually low quality. So, you'll want to get a new lens along with this. My only minor complaint is that the screw to hold the nozzle on is a bit lame, small screwdriver needed. A thumbscrew would have been more convenient. But, that's a trivial fix.

I 3D printed a cap for the stock K40 laser head to provide air assist. It wiggled loose and the laser cut the 3D printed cap open. I replaced the stock K40 head with the Cloudray head, tested the alignment (it was great), hooked up to the air pump and started cutting. Air assist is almost necessary. Happy I got it.

Works great on my Monport K40 laser cutter. Its well made also.

Excelente, facil de instalar

The air nozzle tip is very weak.
