Hi Steve, I have a question regarding the recycling of the laser optics. Is it possible to resue the lens if appropriately recoated ?

Thanks for explaining that lens diameter does nothing... I was wandering why the different diameters

Is great I learnt from you

I could not agree more with the many that have watched this video and still cant adjust their machine correctly I believe a more realistic video should be an out of alignment laser machine being aligned in detail, that's a video that would help more

Interesting tool, since I just bought a used K40. Are you not supposed to wear safety glasses while operating the laser, or am I missing something?

ขอบคุณมากๆๆ ช่างที่มาจ้างซ่อมไม่สามารถแก้ปัญหาได้ คลิปนี้ทำให้แก้ไขได้

Absolute genius!!!

Damn vertical videos. I refuse to watch.

I wish you'd film in landscape, but otherwise, great videos and products. Thank-you.

I have one and it works fine except that it eats batteries! Offering an adapter to plug in a power adapter would make this so much more useful.

I thought this would really speed up my alignment, but man, it's been a bit frustrating because you don't actually show how to do it. You're assuming that the viewer knows 90% of what you're talking about. I wouldn't have purchased this if I did. Do you have a better video or document other than the 1 in x 1 in piece of paper in 3 pt font that was in the package?

Thank you for a fantastic video, I have purchased your laser alignment tool. I had one question, you mentioned a Method at the end, I could not make out what you said, it sounded like Swartz Alignment Method. Would you be so kind as to give a link to this method you mentioned so I can finish up the alignment as you have and as you intend on finishing yours please ; ) Thank You again.

Please link this document. You seem like someone that really cares about details and quality - I’m sad to say that this doesn’t reflect on your website. Totally convoluted navigation, the product pages have mostly marketing speak and absolutely no details about the products.

This is a very handy tool. When I first set up my k40, mirror 1 was so out of alignment that the beam was leaving the box altogether and burning into my 3d printing table across the room.

I was a laser tech where we used 100 w and 250 w co2 lasers, we had air flow coming into the lens holder to always have positive pressure so no smoke came in. We maybe cleaned the lens once a month (with acetone). They ran 24hrs (some down time) 5 days a week. Our co2 came in trucks and was a constant feed type.

I like this company and the lens I bought from them. Looks like I'll be sending them more money. Only obstacle is the wife... Looks like back massages and Framboise will be needed.

Just received my adjustable head for my k40. Could not be more happy with the quality. However i am trying to set some standards for how high the head should be above the work surface. I am cutting 3mm acrylic mostly. Any recommendations?

new to this, and i do appreciate the video and explanation on it but, the zooming and moving side to side throws off the video for me.. my k40 should be here soon, hopefully i wont have much alignment to end up doing on mine, but if so then i'll give it a try, thanks yall

what if the laser tube itself is not alligned well and is tilted up/down or left/right.. would this tool work?

I'm gonna come back and watch this in 40 years when they invent "Talkies"..... can't wait. For now, I'll just test every setting known to mankind in the hopes of being able to duplicate this cut.

Is the focal distance the same as the OEM polar lens? 17mm-thickness of the material

So is the lens come in the steel ring or is that a separate purhase ? And can lens be added to it or every time a lens is needed need to buy the steel ring ? And what about the air nozzle part ? Reusing the Polar OG one or does it come too ? Not much info on that part. Thanks. Looks cool

I think your red dot is moving because the red dot pointer has a small amount of play, it's not completely secure within the laser head. And any bit of vibration effects it.

Wait what!!! That’s it we don’t get the last mirror!? You’re kidding! Whyyyyyyy!?

This should work for the Gweike cloud laser as well I'm assuming.

Wow this is amazing! I hate how I can't clean my lens right now and I KNOW it's not lasting as long as a result. I will be picking up one of these kits and a spare lens right away! Genius

I bought mirrors and lens systems from you. I haven't had the time to use/change/really tune my extremely large OMTech laser. Are the mirrors you sell that much better than what my unit came with? I can't recall the model number. I know it was just about 10,000 usd when I purchased it.

I have a strange issue where all the mirrors seem to be aligned, but only on three corners of my laser. Top left near and far, bottom left near and far and bottom right near and far all line up and hit the center of the head. But as soon as I move it to top right far, the beam travels a full 5mm to the left (looking at the head from the front of the machine) does this sound like a beam angle issue or more of a physical gantry skew?

I thought it was pretty common knowledge not to go over 40% on these? At least I've seen it mentioned on nearly every forum post of people asking about power settings.

I wondered how this was done. Great info.

I bought one of these around the time this video came out 3 years ago. It aligned my 60w laser better than I ever could the old way. Here I am looking at it again as i just upgraded to a monster 150w co2 laser and the proper alignment tool ordered. Don't buy the knock off poor quality OMTech version, get this one. It's worth it and if you have an issue with it the customer service is as good as you would expect from a company where the owner himself is instructing on how to use it.

The boss 1420 has a screw in dust cover.. Any idea what size we should buy?

Hello sir i have the problem for my lens co2 the dot size is big i bought the lens theta co2 i installed it with my co2 tube glass. I changed distance between lens and matriel but the smallest dot size is almost 1.5mm.how can i reduce the size please thank you for your attention

I am a little co fused, after you aligned everything with the red laser you stated do not touch the adjusters again, but yet you went back and turned both adjuster knobs on both mirror holder 1 and 2. Please explain

Has anyone tried wearing them? 😎🥸? I was wondering if a lazer mirror could concentrate light for passive night vision? Kind of like how cat eyes reflect light.

You should never move the gantry's like that as you will introduce back emf currents into the electronics unless they are protected

thank you, i ordered mines

this is why i am considering diode laser instead, hate even the thought of alignment.

Hi, my name is frank I was wondering if you can help me with my problem I replaced all the mirrors and I’m having a problem. Here’s a video maybe you can hel 0:17

Where do u get the alignment tool?

I’m having problems putting my Bing binder lens on notice on once I have a bubble on the other side is flat and on the Bing combiner on one side and has where you can put the lens in and the other side is flat. What side goes to the laser beam.

Interesting... your alignment tool looks sort of like a cartridge. I wonder... Are you using a laser boresight? (I think that I recognize it because I used some with a 3D printed clip to help us align our sound meters for acoustic testing of products at my work.)

I purchased one of these units a few years ago and have only recently tried to use it, However when I noticed when I rotate the always on laser the red dot moves from side to side, it does not appear to be collimated cant it be adjusted. Thanks ALan

Steve you mentioned some focus lens are glued by the laser manufacturers I have a laser they glued , what glue do they use?

Setting aside potential damage from the heat of a laser beam, what is the best way to _clean_ mirrors and laser lenses? Anytime one physically touches a lens, there is a risk of scratching the surface and / or damaging the lens / mirror coating. While alcohol seems to be the preferred solvent because it is readily and inexpensively available and does dissolve oily contaminants to which lasering debris (smoke, etc., from whatever is being lasered). Do vapors from acrylic, “laserable” resins in laminate (Formica), etc., degrade lens surfaces? Additionally, if the cotton swab does not absorb / adsorb everything, it will just smear oily contaminants over the surface of the lens, and if a small, harder piece of debris is between the cotton swab and the lens, the lens will get scratched. Smearing an oily substance over the surface of the glass just helps floating or airborne debris to adhere more easily to the lens surface. So, one solution is to use an ultrasonic bath to “pop off” the contaminants, especially oily substances, from the lens surface. Keep in mind the only thing physically touching the mirror or lens surface is liquid, water with a very small amount of some surfactant to ‘grab’ contaminates, particularly solid debris. So, my basic question, does / can ultrasonic cavitation (cleaning) damage lens coatings, that are generally electrostatically bonded to lens and mirrors? Some suggest using acetone; this is a pretty potent solvent. However, while it does clean lenses and mirrors better than alcohol, there is still the problem of rubbing the surface of lenses and mirrors with a cotton swab. Additionally, many lenses and mirrors are held in place with epoxy (or whatever) to lens tubes. Acetone would most certainly dissolve or degrade (most) bonding agents - and other non-metal components. So again, what is the best way to clean lenses and mirrors, particularly if the lens is embedded deep (2¾± inches) inside a ¾" lens tube? There is very little, as in almost no, wiggle room to clean the lens. Most laser machines now have their lenses “enclosed” in a metal tube or housing that precludes a lot of debris from getting on the lens in the first place, still the lenses and mirrors in these seemingly well sealed lens assemblies still get dirty.

This is an extremely insightful and informative video. Thank you for sharing it Mr.Walters. (Also... had to have a peak at Zemax... those graphs are so informative I kindof wanna make some myself).

I was not able to locate a pdf of this chart on the website. Is it somewhere to be found? Of course one could recreate it (or even make an interactive version), but Im wondering if it is available as a resource somewhere. Thank you for insisting on these key points regarding the beam diameter.

Thanks for that stress visualization video with the polarizers! I guess gluing really is the way to go here. (Also, nice seeing GIMP in the background there.)

wow you do actually make them in usa, good to know! Bought cloudray garbage lens from amazon and it is already all peeled after 3 hours job... Chinese junk. Saw your products on amazon, but no lenses, only full assemblies.
