Such a cool tip thank you mate, another one I saw was the oven grate tray as a cutting bed? That’s so much cheaper then a honeycomb metal board.. I’ve just got my blue diode 40w 445nm 4.5w atomstack p7 laser, what laser safety Goggles would you recommend?
Just used a “modified” version of your method. We found that direct contact with our honeycomb bed can cause spotting on the back side of very thin glass. We elevated the glass using magnets under areas that were not being engraved and got beautiful results with your settings. Thanks
@@PawPawsWorkShop You have to put a thick coat on. My first time it was see through, but since then, I just use more paint and it comes out perfect. I haven't tried the Rustolium trick yet.
As I learn my new engraver, one thing I don't often see it the power of the laser used. If I know my Atomstack A5 Pro is a 5W laser, I would expect settings would be similar for a different brand with a 5W later. I'd love to see more information like that in videos of this type. That would be helpful for us newbies trying to understand what settings we need to be using to get similar results.
In that case would a piece of black sign vinyl on the underside of the glass not be much quicker and work just as well? I understand that you can’t laser directly onto vinyl/pvc due to the poisonous fumes but with a glass tumbler you could also place vinyl on the inside if it’s simply to block the beam Save a lot of painting, drying then washing or would that not work for some reason?
Questions for you..... I have a 10W diode laser so do I still use 60% power or should I use more also if the paint is there just so the laser can see something, can you use a black piece of paper instead ? Thanks for this video...
Thank you!!! I am new to the engraving world and glassware was one of our ideas for sets, but I couldn't figure out why it wasn't working as my 20W laser clearly states it works with glass. Now I did notice the laser going through both sides of the cup but, still didn't click that I needed to temporarily paint it.
The laser basically chips the glass away. It does etch the glass so that you could add paint. Not sure if it would wipe off when cleaning the surface of the glass. Because it etches the glass it may have rough edges and give you a crisp clean look.
how long did it take to dry? I am trying it out right now and is still wet after about an hour, so I am letting it dry in room temperature overnight, hope it is dry in the morning. I did one thicker coat to get it opaque in one coat.
Hi mr Paw! I’ve a question, this process works for Transparent Acrylic? Cut and Engrave? Please! And if not works, can you make a video showing how can i do that? Cut and Engrave the Transparent Acrylic! Bless up Mr Paw!
Here is a video ua-cam.com/video/7VwU4a54zuI/v-deo.html This is how I do clear acrylic. The diode laser will not engrave the clear. The laser goes straight threw the material. In my example the metal is heated and creates the image on the acrylic
Hello, thankyou for the video. I want to try this out but I live in europe and can’t find the spray you are using. What are the specifications of this spray? I can only find permanent sparys who are not washable. Can you help me with finding a similar one to yours. Thankyou
For the glass it is the cheapest tempera paint available. This is a common paint used in elementary schools for kids. For the white tile method you need a paint with titanium oxide in it. This usually is found in white paints.
I got a question for you Paw Paw, I have the long mill Mk2 30 x 30 and interested in buying there version of the laser. Do you think that with the same parameters and process, I would still be able to have the same effect on glass? Not to sure, kinda new to all this. Thanks
Based upon the finished product from this video, it appears you only did the tempura painted glass. Did the spray paint not work? Do you have a photo of the finished spray painted glass?
The black under the acrylic is the focal point of the laser. The heat transfer to the acrylic. Here is a video. ua-cam.com/video/7VwU4a54zuI/v-deo.html
Why do you coat your glass first? I have laser engraved glass exactly once just to see what it did. I dint cover it and it cam e out decent. Curious to know what I am missing.
When you laser the glass how did you get the white color? I love the project and am trying to learn. I did a pie plate but it’s difficult to see the etching because it’s clear unless I have a dark backround
I would try using a white paint, if you intend on eating on the plates it could be bad idea,, as thhe food and such will get into the engraving, another thing that works on glass or plates, is T-O Titanium-Oxide, comes in powder form and you mix it with anything from water to paint thinners, I used plain alcohol as it helps the drying time, as anything you use it needs to be put on thick, so several coats work better.
Thanks for share, I'm wondering, generally we saw that unpainted glass is engrave by laser, why don't you try it? What is difference other lasers? By the way, is there any chance reflection from mirror (or glass) to laser source? If you have knowledge about that...
On a 20 watt laser it output is about 5.5 watts and 60% power would be about 3.3 watts. Determine your output. I would suggest about 80% power and 20ipm. Test, test and more tests
@@PawPawsWorkShop Yeah when you said 20w alien laser I immediately jumped over to their site to see what the actual output is. SO many chinesium lasers rate the laser by the power consumption NOT the optical output. Now with that being said there IS a company (I forget which) who developed and just released a diode laser that IS 30w. What they've done is ganged up a number of diodes and then combined the lasers via a prism to make a beam that has all the power of all the lasers combined. No info on when they're going into production or the cost as yet. It was this past summer when I read about it.
First of all, from one army veteran to another, thank you for your service. Secondly, great video but I noticed you used tempra paint and spray paint but only showed the results for one. You may have already answered but, how did the rustoleum spray paint turn out?
This is awesome! Instead of using paint would a piece of black paper work taped down? I don’t have my cnc machine yet to try and do t k ow if anyone has tried this.

Hi. I have just got my self a sculpfun s30 laser and put it together. I want to try laser on glass and have found your video quote helpful for information on getting setup. What i want to ask is would i do the same settings still as in your video.
can we engrave on acrylic using 20w or 15w DIY laser ? and we have to paint it black too? why can not we engrave transparent acrylic directly with 20w laser?
Yes, you can engrave. Dark colors are best. The diode laser just shines through the clear acrylic. I have shown engraving on acrylic by actually engraving on the metal below the acrylic and it will burn onto the acrylic
The glass is etched. You are seeing the white of chipped glass. The paint is used for the diode laser to have a focal point. The paint is completely washed off after engraving
Just as many others have said here, I have learned a lot watching your video's. You are an excellent teacher and easy to follow along with. I am more O.J.T. as opposed to reading. Just seems to work better for me. As always, Thank You Sir for sharing your ideas and wisdom. Looking forward to more of your instructional video's!
Bro thank you so much, great video- you compared the two strategies you had in mind and tested them out to show what works. Thanks a lot man, appreciate the upload
Thank you. This was great. It worked well with my little 5w diode. Since it went well I'm going to grab a rotary now and play with glasses! I was reading up on the Cold Galvo and the idea of zinc makes me nervous.
I'm new to this. My question is how are you getting it to engrave correctly. My Xtool (using lightburn) My images are coming out backwards. I have no clue what I'm doing wrong.
You are not doing anything wrong. When I load an image before I select the machine the image is always reversed. Just mirror the image and continue. If you are using the RA2 then check before you engrave, you may need to mirror the image there also
You can save a lot of time by just placing the glass on a piece of black card stock, reverse the image, and set the z height to the black surface then put the glass in place. The bottom side of the glass will be engraved. Give it a try.
This is just inexpensive single strength glass. I use tempera paint to paint the glass. Chose the image and you are ready. Do some tests to get the best power and feed rates.
Great video! I've had my D1 for about two weeks and I am learning a ton on these videos! So much to learn and I am absorbing all the information that you out out! Thank you!
I have never heard of using kerosene. My wife produced stained glass on a commercial level both nationally and internationally for ten years. She never used kerosene to clean the glass. Soap and water works well.
@@PawPawsWorkShop That's what I was taught and never I challenged it. It does work very well and I never had a problem cutting glass using that method. I think it may be easier than soap and water because it evaporates very quickly and you don't have to dry it. I guess there are many ways to skin a cat - not that I'm recommending skinning a cat :)
Kerosene is used to cut glass because it lubricates the cutting wheel. The glass is not clean but in fact oily with kerosene. Use alcohol to clean glass.
No, the tempera paint is the cheapest low quality paint used most commonly in elementary schools for kids projects. Not sure what is the equivalent in Brazil
Thanks for the video. Yours was concise and told me just what I needed to know without a lot of worthless chit chat. I did a LightBurn materials test and the 30/60 setting gives great results. Some of the other settings in the materials test provide a nice look as well if you are wanting to vary the shading. Excellent video!
This is a great video, very clear and easy to follow! I just got my 10W D1 and a friend of mine wants me to etch his tempered glass side panel for his PC. Would there be anything different to the process for tempered glass, or would I be able to prep and engrave the glass using this same process on tempered glass, do you think? Any help would be greatly appreciated, as tempered glass is so expensive to buy and test on.
The settings will vary greatly with the different lasers and types of glass. I give the settings I used in the video. Start there and experiment with different settings
Hola tengo una neje master 3 plus y compre pai de 0,3 y 0,5 mm para hacer stencils pero equivocadamente compre de color blanco y buscando porque no se cortaba vi tu video. Hay alguna forma de cortarlo?
Great tutorial, unexpected that the brush painting would be so clear. Have you ever tried (or considered) blackening with soot from a candle or tip of a lighter flame? I expect it will need a thick layer of soot.
I purchased a Trotec Rayjet 50. Is the techniques the same? Also what kind of image do you use and what preparation must you do to get the image ready for engraving?
It seems to me that if you can engrave glass with your 20 watt laser at 60%, one could probably engrave glass with a 10 watt laser at 100%, perhaps a bit slower. What do you think? Your tempera paint technique is very attractive.
What was the point of using the spray paint? Why didn’t you show washing the tempera off the glass after engraving? How does burning the paint away actually etch the glass?
Great videos! I just watched this video on how to laser engrave on glass. I previously watched your video on how to laser engrave on acrylic. Can either method be interchanged? I.E. can you engrave on glass if using the acrylic method? If so, which method is easier to setup and cleanup? Thanks, keep up the great videos.
Nothing. With clear glass and a diode laser it would just go straight through and not do anything to the glass. You need the paint the glass for the laser to focus on it
Thanks to everyone that let me know of a voice over problem. Hopefully, problem solved.
Yep, you got it sorted, thank you

At 7:05 you can see his laser is a 20W, so it would be 280% on a 5W.
@@shigerufan1 actually, 5w/5.5w is just barely eniugh, just needs to run the laser 5-6 times slower. But anything under 5W wont create enough heat.
Thank you for your wonderful video how is the settings transferred to that x tool D1 laser?
The settings are in the library. Just open the file and select the layer. Then in the library select the desired selection and add to the layer
is the purpose of the paint simply to stop the laser shining through or does it also make for more detailed lines?
The diode laser does not see the glass. It would go straight through and do nothing to the glass. The paint provides a focal point

also if the paint is there just so the laser can see something, can you use a black piece of paper instead ?
Thanks for this video...
You will need to run a grid test to determine the best power and speed. Yes, you should be able to do that with the paper
Changing the settings, will work on acrylic as well?
love it I am a carpenter and one thing is definitely true people over-complicate things
Couldn’t agree more
I'm confused on which laser was used. Is the 20 watts the input power or output power of the laser?
How did you get the paint off after you etched it to reveal the clear glass and etched image?
I used tempera paint which is water based. The paint washes off very easily
Brillant video - Can you please tell me if you can laser etch the reverse side of a mirror (the coated side of the mirror)
Yes, you can. Mirror the image. You will need to test the power and speed on the mirror. Also, use in a well ventilated area
Thank you!!! I am new to the engraving world and glassware was one of our ideas for sets, but I couldn't figure out why it wasn't working as my 20W laser clearly states it works with glass.

Glad I could help!
Can you etch glass deep enough with a diode laser to paint the glass, wipe it off, and have paint left in the etch?
The laser basically chips the glass away. It does etch the glass so that you could add paint. Not sure if it would wipe off when cleaning the surface of the glass. Because it etches the glass it may have rough edges and give you a crisp clean look.
does this just give a frosty look or is it gritty feeling ontop of glass?
It actually etches the glass. An alternative is to engrave on the back of the glass. You’ll get the same image just smooth on the surface
@@PawPawsWorkShop oh ok that just answered it then haha thank you!
@@PawPawsWorkShop Remember to invert the image if you do the back.😉 Clackshack has a video where he LED backlights a mirror. It looks great.

this guy made this so easy. Clear I seen videos where they doing all types of things to paint the glass for the same result.
What was the point of putting paint on first. Wouldn't the laser etch the glass anyway?
The diode laser needs to have the paint to focus on. Without the paint the light would go directly through the glass

Kerosene is used to cut glass because it lubricates the cutting wheel. The glass is not clean but in fact oily with kerosene. Use alcohol to clean glass.
Hello Paw Paw. Is this Tempera Paint the same as the Spray High Temperature Paint sold in stores?
No, the tempera paint is the cheapest low quality paint used most commonly in elementary schools for kids projects. Not sure what is the equivalent in Brazil
Tks; Is it Gouache Paint?
I do not know that name
Thanks for the video. Yours was concise and told me just what I needed to know without a lot of worthless chit chat. I did a LightBurn materials test and the 30/60 setting gives great results. Some of the other settings in the materials test provide a nice look as well if you are wanting to vary the shading. Excellent video!
Thank you very much. From you avatar it would appear that you are a pilot. Is that assumption correct?
Yes. Love flying even more than playing with my Atezr P20.
Brilliant tutorial, can i ask if the spray paint you used was oil based or water based?
The spray black was just rustoleum and it did not work as well as the tempera paint that I brushed on
@@PawPawsWorkShop I can't get Tempera in Ireland, Is it acrylic based?
No, it’s a very cheap paint that is often used in elementary school for art projects
Great video. What laser did you use for this. How can I convert 30 in/mm to mm/mm
I used the FoxAlien Reizer for this engraving. To convert inches to mm.
1”= 25.4 mm.
@@PawPawsWorkShop I have a Ortur 20w-5w output
This is a great video, very clear and easy to follow! I just got my 10W D1 and a friend of mine wants me to etch his tempered glass side panel for his PC. Would there be anything different to the process for tempered glass, or would I be able to prep and engrave the glass using this same process on tempered glass, do you think? Any help would be greatly appreciated, as tempered glass is so expensive to buy and test on.
Tempered glass is much harder. You will need to adjust the settings. A little experimenting would be necessary
@@PawPawsWorkShop sounds good, thank you!
What settings would you use for a Sculpfun S9 diode laser?
The settings will vary greatly with the different lasers and types of glass. I give the settings I used in the video. Start there and experiment with different settings
@@PawPawsWorkShop OK, will do, Thanks, and thanks for all your excellent videos. Greetings from Mexico City.
Hello, could you indicate the link on Amazon of the product that passed on the glass before engraving, please.

New to laser engraving and just found your very helpful video. Thank you. Can you share your compass rose file?
Hola tengo una neje master 3 plus y compre pai de 0,3 y 0,5 mm para hacer stencils pero equivocadamente compre de color blanco y buscando porque no se cortaba vi tu video. Hay alguna forma de cortarlo?
Does this work when engraving a photo image?
Different settings but it works on glass also
@@PawPawsWorkShop thanks
Will this work on PolyCarbonate (Makrolon Plastic)?
That is a very hard material. Not having tried this material I do not know if it possible
'preciate ya Pawpaw! hope yous and yours is good and happy
Thank you very much
Great tutorial, unexpected that the brush painting would be so clear. Have you ever tried (or considered) blackening with soot from a candle or tip of a lighter flame? I expect it will need a thick layer of soot.
Yes, that did not work.
I purchased a Trotec Rayjet 50. Is the techniques the same? Also what kind of image do you use and what preparation must you do to get the image ready for engraving?
Exelente tutorial.
Cual es el lado de el vidrio que queda mejor, el lado con pintura o el otro lado.
Gracias.
It seems to me that if you can engrave glass with your 20 watt laser at 60%, one could probably engrave glass with a 10 watt laser at 100%, perhaps a bit slower. What do you think? Your tempera paint technique is very attractive.
That's possible, all you need to do is to test it out now.
I will and let you know how it goes.
Thanks
Ive tried this with a 5W laser diode running at low speed and seems to work well.
What is the actual engraving power of your laser? 3 watts? Found it... 5.5 watts optical... thanks!
On a 20 watt input you generally get about 5.5 watts output
I use the black anodised business cards placed under the glass and this engraved fine
Yes that will work. The laser reflects off of the black card. Thanks for watching
Can and should this be used with a co2?
Can 10w cut 8mm acrylic
That may be very difficult
@@PawPawsWorkShop have u tried yet?
You’re awesome PawPaw! Thanks for these great videos!
It is my pleasure. Thank you very much
Did you ever try a piece of vinyl on the glass and laze that?
Cool result! Can't wait to try it myself soon!
You can do it.
What was the point of using the spray paint? Why didn’t you show washing the tempera off the glass after engraving? How does burning the paint away actually etch the glass?
Focal point for the laser
Would this work with the JTech laser?
Yes, you may need to adjust the settings or do two passes
Does the spray paint wash off with water?
Yes, on the glass I use tempera paint and it washes off easily
Great videos! I just watched this video on how to laser engrave on glass. I previously watched your video on how to laser engrave on acrylic. Can either method be interchanged? I.E. can you engrave on glass if using the acrylic method? If so, which method is easier to setup and cleanup? Thanks, keep up the great videos.
No, it is two different methods based on two different materials
Do you think that this will be possible with 5-6W laser head?
Yes, I think it would work. You would need to adjust the settings
What is tempera paint?
Tempera paint is a cheap inexpensive paint usually used in elementary schools for kids art projects.
Dollar Tree has it. I assume the others do as well.
Hi, just by chance came across your video and was impressed. What would have happened if you did not put the paint on the glass?
Nothing. With clear glass and a diode laser it would just go straight through and not do anything to the glass. You need the paint the glass for the laser to focus on it
