Cloudray12/18mm FL50.8 & 16mm FL25.4 Laser Head With Air Assist For K40 Laser Engraver Cutter

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.

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.

Works as intended but shipping took forever.

Excelente, facil de instalar

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

The air nozzle tip is very weak.

I purchased the OMTech 40W CO2 laser engraver Cutter. After initially cutting simple cardboard and seeing it catch fire, I decided air assist is a must. Upgrading with Cloudray's Laser Head with Air Assist has made A HUGE IMPROVEMENT! HOWEVER, there were some drawbacks which I'll list below:1) Upon receiving Cloudray's product, IT DIDN'T LOOK EXACTLY LIKE THE PHOTOS but looked exact to the one in the video. The Laser Head did NOT come with the metal clip pictured on top so I had to use the metal clip on the stock Laser Head that came with my K40.2) For the Air assist Laser head to work properly, it needs to completely replace the old one to clear the bed/vent. That being said, IT WAS A HUGE PITA TO PULL THE STOCK LASER HEAD OFF. After struggling with it for some time, I finally resorted to using WD40 and applying tons of torque to twist the Laser Head apart from the metal plate it was sandwiching. Highly recommend unscrewing everything to separate the metal plate with the Laser Head from everything else before trying to unscrew the stock Laser Head apart.3) STOCK K40 LENS WILL NOT FIT WITH CLOUDRAY AIR ASSIST LASER HEAD. I purchased a 18mm Lens and it works great with that.

I need to revise again. The diameter of the middle part is too large to fit inside the standard k40 head assemble. therefore it sits on top of the bracket instead of inside of it. That causes the whole assembly to sit low on the beam path (i.e the beam hit's high on the 3rd mirror and can not be adjusted lower.) I have an omtech k40 and this nozzle does not really fit well. I've 3d printed a collar that raises the mirror a little, but it still can't be centered. Lowering my rating to 3 stars. It works, but not as well as it should when advertised for a stock k40.My bad. The adapter ring was there. It was not visible unless the head is disassembled. The assembly is 4 pieces, not the 3 pieces I identified when opening the package. After noting the screwdriver slots in the middle piece I discovered that the 12mm adapter ring was installed, not packaged as a separate piece.My bad. Apologies.I purchased this head to add air assist to an omtech 40w co2 laser. The description claimed that it would work with the stock 12mm lens, however the adapter ring shown in the picture was not included in the package.

Great upgrade!

Works perfectly with the k40 co2

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

Gutes Produkt, passt 100% im K40. Hatte bei der Installation ein kleines Problem. Habe nicht gesehen, dass man bei diesem Kopf das Gewinde noch herausdrehen kann. Wollte aus diesem Grund schon das Loch (Aufnahme) vergrössern. Nachdem ich mir die Artikelbilder hier noch einmal angeschaut habe, war die Sache klar. Man kann einfach das Gewinde (mit einem Handtuch) herausdrehen. Dann passt der Kopf auch in das K40 Loch.

Ottimo prodotto, economico ma fa il suo dovere. Qui puoi montare lente 15/18/20. Io sono riuscito ad usare la lente originale k40 aggiungendo una guarnizione da 1/2 pollice che aderisce bene con la lente.
