Laser arrived today, but it looks different than other i seen.
How about adding a air assist to this one? anyone tried and what modifications was needed?
Thinking of Lightobjects air assist head, but not sure it will fit properly.
Pretty sure i have to mod it, but if anyone already done it i would be glad to see how you did it 
Oh wow, interesting indeed. Could you take a few more pics at different angles? I wanna see how this thing is made.
more photos please (general view, PSU, board, mirrors)
where did you buy it, price tag ? link ?
thank you
the hole at the tip of lens holder look like a good candidate to have the air assit. (ball pump needle ?)
More pics coming up later today. Was surprised, as it has a water-temp and psu-temp gauges on the top, + emergency stop and some more upgrades 
Nice! Be sure to post a link here when the pictures are up. I seem to miss half the stuff that gets posted here.
It definitely a different design than the K40’s I’ve seen. Look under the plate that the lens is attached to. If it’s threaded you may be able to screw in an air assist. It wouldn’t hold the lens so lens size wouldn’t be a factor. As long as the threads were the same it should work. If it’s not threaded you’ll have to get creative and figure out another way to mount it.
If you’ll tell me the size of the lens-holding-bar, I could 3d print you one…
Then again, I think I’d take some copper tubing (or automotive brake line) and put it through the hole on that bar and bend it so the air goes where you want it.
It looks similar to my setup on the 50 watt…just missing the head…but the rail looks the same and the gold aluminum angle bracket is the same as mine…all the holes are in the same place.
Pictures of the laser on the link below
Bought at Aliexpress for $604 with shipping to my door. (Sweden). Seller was “Wonderfull Power Machines” They had sold 10+ of them and good rating.
Only one small damage on the back edge (pinches the door to the laser tube a bit), but no harm to the moving parts, squared it up and checked.
Going to the store now to pick up some cooling parts, everything was included, but the pump wants a 12mm tube, and the tube in the machine is 6mm
Not started yet, so no clue if it works… but sooon
@HP_Persson thank you for the picts, very interesting indeed community wise. could you top it up with some electronic board details (& picts) could be interesting for potential update. Psu ref, Board ref, connectors type (to motors, end stop), same link is fine. inside photos of electronic side (under control board).

Darn, i forgot that. Coming up more pics in a few hrs
And some data on the boards.
I looked into it yesterday, the board had a cover, but i can easily remove it and check whats below!
Where did you get this version at and how much was it if you don’t mind me asking
@3D_Laser CHeck out the details in my earlier posts above about where i got it and name of the seller 
$600 shipped to my door
The images in his ad shows 3 different types, none of the version i got. Maybe just coincidence?
4 more pics added to the link.
Could not access the board right now, it was bolted to a panel and that panel bolted to the frame wich needs to be removed to lift the case/top from the board.
Will do that tomorrow when i got some better tools avalible

Laser fired up, water pump changed to a bigger (safer?) one, air system rebuilt, bed squared up, mirrors aligned and all electric connection checked, some soldered and re-crimped 
+Peter van der Walt thanks for the idea about a small pipe, picked up some copper brake lines today (5mm) and grabbed one of my air pumps from the fish tank, probably too small but it´s a start
Tomorrow is the first engraving/cutting test!
Wow I’m impressed with the overall quality. This manufacture really went out of there way.
