- Engraving ~3mm window glass with cheap 40W made in China CO2 laser. Cutting is not optimal, it is only first test. No need to use so many passes, as cut line is quite deep. I'll test in curves mode next time.

Excellent beginning and results. Caution maximum mA value for 40W laser tube should not exceed approximately 12 mA. Greater settings will over-drive the laser tube and deplete the tube CO2, shortening useful life DRAMATICALLY. Perhaps even to months. Also saw dramatic glass etching improvement when, commercially available, glass etching mask film used to cover glass.
Just passing on techniques learned on you-tube.
Recommend, to all, reworks learning lab video series with Russ Sadler.
Enjoy and stay safe, i.e. use protective eyeglasses when cover is open. ron
awesome. I've been thinking about this, but wasn't fully sure it was possible. thanks for the video!
thanks for the video, I liked it
that crackling noise gives me the tingles. ASMR vedoes never worked for me, btw. :D
Hi,
Thanks for the video. How deep can single cut go?
And what is the width of the cutting lines?
I am looking for a laser to cut 0.5-1mm glass.
Is as much as 0.005" (127μm or 0.127mm) of material removed in the process? Do you know the actual depth of cut of the image?
hey,savel, did the software for the CNC come with it and if it did what brand? I have "benbox" and "mini laser" software. the benbox doesn't work at all with the laser and the mini laser software is very limited.
Hey guys, what's best affordable option for Crystal glass inner 3d engraving? Thanks!
Good stuff .. although the correct laser for that work would be a UV Laser , with UV you can get a very pro finish .....
The handling of glass in that manner, will eventually lead to lacerations.
what is the working area ? will this work with 8 mm acrylic sheet for engraving and cutting ?
I have a laser like yours. What was you power out put set at?
Very interesting. We do warm glass at my wife's studio and cut by hand or with a diamond saw. I'll have to try this as a technique (I have a laser engraver but have not tried it with glass)
Did you eventually try your laser cutter with glass. How'd it go?
@@realotobi I have not. I don't actually use the laser cutter that often. I have a bunch of upgrades I'd like to perform but have been spending most of my time with 3d printing.
How much power did you use to engrave and cut?
Nice,do you have to put a coating on the glass,or use "as-is".Thanks!
A little bit of saliva on the glass works well
I made some engravings onto hardened glass disc's. I did try and use cutting and marking too but made the glass molten and started cracking. Did you find after the engraving you have a brittle layer of glass left?
+Slice Workshop my laser is too weak to "real cut". It make only small "crack" line and glass is broken along this line, like with regular glass cutter.

hello
can this make 3d photos ?
please advice ...
Hi, interesting video.. What software do you use to run this please? Thank you

Quite amazing. Was it just clean glass or did you coat it with something? I was wondering if this could cut lexan/polycarbonate.
+lunar3660000 Just plain window glass. And yes, it can cut plastic, wood, etc.
+lunar3660000 Cutting the plastics or similar materials with laser can be tricky and troublesome. I tried cutting acrylic glass with 80W laser and, due to temperature, the egdes started melting. Also, they had cone shape (the part closer to the laser head was wider than the other side).
( ͡° ͜ʖ ͡°) either it was very thick plastic, or your laser is not giving 80W optic power. My laser was quite weak at first start, but the problem was with laser beam alignment. To fix it, I just needed to get some masking tape, screwdriver and some youtube. :)
Thanks for the video. Was thinking of getting this laser myself, my question to you is, how thick glass can it cut? And how is "curve mode" working?
40W Chinese laser is specced to cut up to 4mm thick materials such as wood or acryl, but I don't think it'll cut through the glass. Engraving is possible. Cutting? I don't think so.
Can you also engrave glass with thickness, so you can setup how thick the engraving is ?

where would a guy order one and what is the price?
hi sorry for my bad english....why when i engrave acrylic...text or picture are transparent...?without contrast
plastic melts. To engrave such plastic, power must be very high and impulse very short. This evaporates plastic and do not melt.
In this video I am engraving real glass, not plastic.
i'm using benbox. what would be the settings to actually cut through the acrylic?
Elmer Fudd who knows what is benbox? To cut you need laser power and cutting speed. Optional- compressed air aid. All other fancy words are only sales managment.
Hi, how little is the spot of the laser on the glass......i see big differenze from wood to glass.
+Alessandro Zupo spot size depends on optics. Adjust height of the "table" to get minimal spot. Also, glass shatters on in own size. Need to vary power and speed.
Yes i know, i did buy a 38.1 mm focus for have a smaller spot then 50.8 original lens..... but the result is the same. If you have high quality image in zoom of the glass engraver i would like to see. Maybe we can exchagne some information. In Facebouk group "facebook.com/groups/888394261237059/" call "chinese K40 Laser Group" you will see my photo and video of my glass engraver.
hello, can you test this machine with " metal " items ??? ( aluminum for example ) not for cut, only for engraver. Is possible with only 40w???
would love to know as well..
fiber full stop man
40w fiber
Well, 40W should be enough for the engraving. But 40W is really small power, especially with these Chinese optics, so there is a chance that the effects of it would be not very rewarding.
Metal sinks the heat away too quickly.
How much does that thing cost? you bought the entire machine, or just the laser head and support equipment, for an existing CNC?
+ComandanteJ ~900USD with VAT, shipping and other stuff. Now it must be cheaper.
+ComandanteJ 300x200 mm 40W cost $400. don't know about shipping.
+thePavuk its 1000$ can i buy one on ebay
janik carrier version without air blower and without motorised z-axis starts on $400
+thePavuk yes i know but i pay this with shipping the machine are 500$ can without ship
What does CO2 means - you need to provide CO2 gas for it to work? Is there any other supply you need to provide prior to starting work?
+peshgeorgiev No, it is so called "sealed CO2 laser". Only thing I need is to cool laser with water. I do it with big bucket and small pump (pumps was sold with laser).
+savelkaunas Thanks, can you tell me if the laser has life. How long can it be used or can it be used continuously for small commercial work. Also what is the exact model of the one that you got? I found a lot of complains of lasers like this? Yours seems to work nice.
Yes, the laser has life. For the good laser tube, it can continuously for commercial work. But for the small factory's laser tube, the quality can be guaranteed.
how high of a workspace do yo have between the item to be engraved and laser, I want to laser cut dice would this be possible with this machine
+bfg2600 depth is changable. You can tune it to your need simply by changing the height of the table. Engraving depth is depending of focal length of the laser lenses (some types are available).Cutting depth also depens of focal length and power of laser. Also, some problems can be from the fumes- they can block beam.

Is not good for cutting, I think manual mode (using a diamond cuter as usual) is better. But for engraving looks usefull
I have similar laser like yours, but I don't have this honeycomb-like working tool. Did You make it by yourself?
And from what producer did You buy Your machine? I want to cross-reference the offer. ;) For mine I paid around $500, with shipment included.
+( ͡° ͜ʖ ͡°) I made base by myself. I don't know who is laser manufacturer- just random seller from ebay.
CAUTION, most eBay laser offers are disingenuous. Have been in conversion with Chinese laser machine manufacturer for several months discussing eBay buyer problems. Chinese laser machines are not the problem. Ebay laser get rich sellers without warranty or service are the problem.
Became convinced of their honesty I just purchased my laser machine directly from manufacturer.
If I can help anyone resolve a concern or technical problem, before a purchase, please contact me. Fair warning, I am not a conflict resolution resource after a purchase except with my company product sales. I will FREELY try and help answer any questions. No need to buy anything.
where did you bought yours?
I work in a company which imports these kind of laser engraving machines directly from the producers. That's how I have one.
we are laser factory from China supply laser engraving machine , fiber laser marking machine , laser cutting machine , hope can have chance to cooperate with your esteemed company , whatsapp 0086-13793068157

You opened the interlock to a 40 watt infra-red laser and the machine did NOT cut out? =O I thought that power could blind - even just off the specular reflection.
I have one of these chinese k40 40 watt lasers and can say that they do not have a shutoff on the lid. also the red acrylic window is just for looks, mine has a clear window in it.
also most of the time I use it with the lid open.
He will be blind in a few years.
Interesting to hear that about the red lid. Though the lid hopefully would offer a little protection as the acrylic is UV absorbent (hence why the laser can cut it). I can confirm that these lasers have no interlock and also no protection for if the cooling water flow is not good. I have purchased parts to address both of these but am just being careful in the meantime.
Not true at all. Some wavelengths your blink reflex wont respond. I punched a hole in my retina with an infrared laser that threw a reflection off of a piece of material. No cure for it either.
Jagged edge
Dear Lord, add a micro-switch to shut the laser off when you open the door. Even reflections off these things can blind permanently and instantaneously. Imagine the guilt you'd feel if someone you loved opened the thing up w/o protective glasses and caught a blinding reflection.
Many people do. I just don't open the door when the laser is going but I intend to add this and a water flow cutout.
Thanks OSHA agent.
@@TimDonk My job here is done. Thank you
you have to add blower for its working, which can engraving and cutting better than this
it is better to use acrylic. there are too many sharp cuts for glass
Acrylic lets out way too many toxic fumes... proper ventilation is required
you can get a lot more detail using masking tape.. I just saw it in another video :P
wait...where?
@@devinkk ua-cam.com/video/zCpZu-UrEjQ/v-deo.html
Laser should not be used without immense protection for light leaks.
Are you wearing laser safety glasses when you opened the top?
Amazing
who is the supplier for this laser.?

Web site please ?
Thank you

Where did you buy it?
You can find one on eBay or Alibaba, but probably You won't get any warranty for it. It's better too look for an importer on Your local market and pay more for a piece. I work in a company that imports these machines from China, directly from the producer, and then we are reselling them on our domestic market. We are of course more expensive then random seller from Alibaba, but we give You up to 24 months of warranty. And I think it's worth the price, because if something happens to the machine (and if You're unlucky it happens a lot) You're not left alone.
would these work on soft metals?
Engraving - yes. Cutting? Forget it.
soft metals?our company have one machine could marking on foods,such as apple,do you need it?stainless steel,carbon steel,brass,copper,aluminum,wood,acrylic,plastic and so on.

can it do metal? thanks
Only 40W Co2 Laser, metal is not ok.
Does my 1000w can do the same?
Yes, why not? It probably runs on the same software as this one.
settings please
They are at the start of the video, but here it goes: 40W laser power, approx. 180mm/s speed, and engraving mode.
AT what price u bought this ? n can u tell me the name of dealer ?
We are this kind of machine's professional manufacture. ^_^
Monica Shao what's your company name and how much is the 20w machine.??and is it enough to engrave pic on iphone??
man as much as i hate to divulge techniques .......if u intend on engraving on glass my friend.....for a clean one you best to put black permanent marker on the glass n polish it off after
Can I know the name and model of this machine?

what is the life of laser & why CO2 ? does it require CO2 for cooling or something ? does it need any external CO2 supply ?
i don´t know the lifespan, but it has an CO2 laser tube which get cooled by an external waterpump which goes in a waterbucket.
THANKS
You should check it with the seller. Some writes that the tube will last up to 6000 hours, but it's bullshit. It's probably around 2000 hours, with working on full power. If You'll work on a lower setup the tube will last longer.
It uses a water-cooled CO2 laser
can a such laser machine cut aluminium plate too ?
No, it can't cut metal at all
@@dfitnic if by "plate" they mean "foil thickness", then of course, but not thick metal.
@@und4287 not even foil thickness. Can't scratch metal at all. You need a fibre laser for that
Clean cut. Bahahahaha

buy a dremel alot cheeper
That's the worst image I've ever seen. Cheap work is not good and Good work is not cheap.
Jeremy BBenthem do you know much about laser etching? I'm looking to etch paper cups at high speed for personalized cups at my coffee shop.
Is the etching speed 1000-1200mm/s ok?
Suggestion: etch the paper sleeve that goes around the cup, not the cup itself. The sleeves can be folded flat, and you'll have a much easier time(and most likely with less expense) than finding a cylindrical laser marking system.
Why not just use a sharpie like everyone else? It's going to get tossed when the person is done with their coffee anyhow?
Yeah. Plus the danger of the engraving weakening the cup. Unless you want online reviews of "I left jb coulter's coffee in my cup holder while I went in the grocery store and when I got back, the interior in my Mercedes was ruined".
Not to mention there are companies that will do custom printing on thousands of cups for much cheaper and less effort.
Jeremy BBenthem the same
