Four years later this video is still relevant and just saved me the biggest headache 🗣thank you for keeping it simple

[@fibranijevidra]

"Now is a good time to inspect your mirror, and lens to make sure they are clean." The best way to do it, is to touch it with your bare hands. Great work!

[@NinjaHempKnight]

I offered the cloudray laser head and mirror mount kit. It actually arrived today. This video was super helpful! Thank you

[@z8ty]

Thanks for making the video... I now feel more confident in installing my new laser head.

[@cliffchism9187]

Thanks for that! I just got my k40 and will be adding the air assist. You just saved me a lot of future trouble.

[@Checkitfirst]

Thanks for the video. I’m thinking of buying the K 40 and buying the air assist with it and your video made it look a lot easier to install that air assist so I’m very grateful.

[@BravoTechnologiesLaserGods]

thanks :)

[@manuelvillalpando6665]

Awesome! Exactly what I was looking for too! Thanks for the tips and your well explained instructions!

[@champyb]

You are a SAINT for this !

[@MilanKarakas]

That is really awesome and simple procedure. Saw few videos where people complaining about. I have no laser cutter, but eventually will collect money. :D And I need any sort of tutorials and advice. Thanks.

[@southmountainoutdoors4628]

Thanks you are my hero!

[@threednutyoung7793]

Great video what was the focal length of the replacement lense? ( 2.0" like the OEM?)

[@DRob70]

Nice video. What is the focal length from the bottom on the laser head to the material?

[@DFesler]

Thank you for your video. On the aluminium adapter ring, does it go on top or under the lens?

[@woogaloo]

Oh my goodness - this was awesome. I've had one of the air assists for awhile, but haven't even tried to install it (partially no time, but partially just scared to mess it up). I'll probably be one of the ones that just puts on half of it. Thanks for the tip of it actually unscrewing. I've not seen that anywhere. EDIT: Scratch that - I just went ahead and switched it all out. I had new lenses for both of them so it just made sense. Do you happen to have a video/picture on where you mounted the air assist 3D bracket?

[@woogaloo]

Sorry about that - bracket wasn't the correct word. Whatever the thing is called that your air assist hose is inside of (the black links). Where did you mount the other end of it? Thanks.

[@java402000]

very nice job

[@P3tonka]

Great video, i just ordered one of these bad boys. Now i need to figure out a simple z table... any suggestions?

[@markmcsweeney3265]

Great video, it helped to do my mod! On question, the equipment holding the airhose, is that something I can buy to guide and guard the airhose?

[@BravoTechnologiesLaserGods]

like this maybe? lasergods.com/cyclops-k40-drag-chain-install/

[@TrueBlueAustralian]

Great video thanks, what size drag chain did you use and what size air hose? Thanks

[@mariogayoso]

Tonight I'm changing one an ugradng the lens. After that I will add the chain. I can't wait to change the bed or do the honeycomb grid. Any recommendation?

[@chubbyboy2242]

Thank you so much!

[@mariogayoso]

I'm installing mine and I realized that the upgrades lens is tiny and I don't know where to put it ...does it go loose inside of the silver ring?

[@KipIddy]

Did you have to do anything to align the laser head so that it’s straight 90 degrees down on your table?

[@Alberto-gi8fb]

Hi, how does air assist help? Or whats the advantage, and also where can i get one?

[@johnm7727]

Quick question. Is it normal for the lightobject lens holder to not tighten all the way to the last thread?

[@Patricksworkshop]

good info thanks

[@deseandukes5375]

Hi I bought this air assist head everything works but the last piece where the air comes in.. for some reason the laser doesn't shoot through but when I take it off it works but I need the air assist

[@DarkooKnight]

I've bought the 20mm focusing lens for my k40 did I buy the wrong size?

[@BradleySmith1985]

the lift table you have . Do you think that will work with the olmetec versions of the K40 I'm using the light burn motherboard

[@StickerBoutiqueInc]

new to this, wanting a k40 laser, why wouldn't you change the top part out? im just new and not really understanding. thank you. I would love to leave the top on as Im not one to mess around with stuff too much b/c i end up screwing it up. can someone help? thank you!

[@quarlow1215]

A question from a total noob. So much so, I haven't even received my K40 yet. What does changing to an 18mm lens do for you. I'm just assuming it sharpens the cut beam?

[@karadanvers6136]

how much torque is needed to get the orig lens holder off? i cant seem to twist it off

[@mariogayoso]

Hey man, do you think that if I have an 12 mm a 3d printed ring to complete the 18mm would work?

[@mariogayoso]

Bravo Technologies I guess we will try my friend!! Air assist me drag chain installed tonight !

[@brra1199]

how many bars recommended?

[@justinrrizzo]

What does this help with?

[@doc_ineeda_win5834]

Do you have a alignment video for after the change?

[@mariogayoso]

I did this upgrade following your video but it seems that the beam is bouncing somewhere because the laser isnt coming out . Any advice?

[@BravoTechnologiesLaserGods]

I would say it's in the alignment. make sure the opening to mirror 3 (in the head) is pointing directly at mirror 2 for starters.

[@gettingpast4391]

Hi what focal length is your 18mm lens? I noticed the lens position is much different with the air assist head

[@BravoTechnologiesLaserGods]

2.0 (50.8mm)

[@ZsMsTroubsko]

I have been struggling with poor-quality laser heads since buying a laser. The head slowly unscrews itself. Tightening metal to metal simply does not work. I have a basic model, any recommendation where to buy a better head?

[@gregorytphotography8056]

Machine Tech for nearly 30 years- use regular clear silicone as a "loctite". I've used this in dirty environments with vibrations and it works great. Best part is it's removable and doesn't damage aluminum threads.

[@iurisilva2337]

Lente de 18mm dá certo?

[@NetoTrabanino]

I bought a K40 and the dealer let me down. I need to buy a light switch for x direction. The head doesn’t move in the x direction. Is there someone who knows where to buy it. Thanks, Raul

[@BravoTechnologiesLaserGods]

cohesion3d.com sells the mechanical endstops (microswitches)

[@dkoldeez]

What Diameter tubing?

[@cspann831]

I've sort of taken over maintenance of the laser where I work trying to transform it from a toy to a tool. I'm learning all this stuff by the seat of my pants here and thanks for the help. I've heard a lot of people say convex side down. Only you say convex up. What is the reasoning ? I already found soot baked onto the lens. Fortunately it came off with a lot of isopropyl and cotton balls. I think I will try an air assist mod. We usually just use the machine for plastic labels and signage for the machines we build. Would air assist help with plastic? I may use it for wood also.

[@ModsAndProjects]

Where did you get the drag chain?

[@BravoTechnologiesLaserGods]

amazon. its 10mmx15mm i think

[@33uses]

When I added a 50L air assist to my k40 laser It turns on and off by itself, what is the SOLUTION please 🥺

[@carloscardenas6466]

Check out American photonic lenses and heads awesome.

[@PeabodysParadise]

I put the bottom half of the air assist on mine and now it scrapes the exhaust port as it goes by it, anyoen else have this issue?

[@jetajockey0]

@@BravoTechnologiesLaserGods excellent, thanks

[@BravoTechnologiesLaserGods]

yes this can happen. many people cut back the exhaust. i have a video on doing that somewhere in the laser playlist :)

[@BravoTechnologiesLaserGods]

thanks :)

[@castortrox]

where did you get the lens?

[@BravoTechnologiesLaserGods]

cohesion3d.com

[@chato555]

You`ve said "curved side up"? That means "belly" of the mirror up or..? Mine stock lens was opposite side and worked more than 2 years 😂😂😂🙈🙈🙈 What's the difference? Any better or worse result? 😬

[@brianfoster7064]

The mirrors that came with my K40 are plastic with a mirrored surface on one side. Total junk. Got CU mirrors to replace them. As to your statement about the way to place the lens, I think I'll follow Russ' directions after having watched his videos that are quite in depth about lenses. Don't know about you, but he has a lot of history with commercial laser systems before getting his "toys" at home.

[@Clarence_13x]

Don’t touch it!!!

[@justasniper83]

That air assist sucks. Via the Venturi effect, it will suck dust in and make lens dirty.... there are a lot of air assist on thingiverse, ready to print and use with a little fan....

[@BravoTechnologiesLaserGods]

yeah they do and my articles on this talk about that. i use the copper pipe air assist and have stl's and dxf's for mounts published
