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.

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.

Fit was perfect quality was absolutely stellar the value for the money was worth it. Ease of installation was there I had my 12-year-old cousin helped me do it. It worked absolutely great and it function better than stock. I loved it. Would definitely recommend to use on any K 40 laser

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.

Perfect

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

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.

This was a gamer changer on our laser engraver. Would recommend it.

ne convient pas pour la lentille d'origine ( sur mon model du moins ) impossible de centre la lentille qui et trop petite par rapport à la bague fournie donc a moins de change la lentille vous remettrez le model d'origine Pour le moment et jusqu'au jour ou je changerai la lentille c'est un achat inutile

Not what i expected. Presure is to soft. Maybe its because of my airpomp, who knows. But its not an upgrade for my Mcgyver type airassist made out of the tip of a pen which provide a higher presure and a clean cut in one pass

Great upgrade!

Er ist nicht ganz günstig, aber erspart sehr viel Nerven. Habe bis jetzt die Air-Assist Düsen aus dem 3d-Drucker gedruckt. Passgenau und ebenso funktionell. Allerdings ist das Plastik gegen den Laser nicht sonderlich robust und auch versehentliches Aufflammen macht schäden. Hab die bestimmt monatlich tauschen dürfen Jetzt mit dem Kopf kann ich viel genauer arbeiten und hab weniger Aufwand. Durch einlegen von Papier in die Air-Assist Düse kann ich den Kopf sogar so ausrichten, dass der Laser wirklich mittig rauskommt. Das ging vorher nur schwierig. Das Ergebnis war lange nicht mehr so gut wie aktuell. Sehr empfehlenswert.
