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?

[@allenhuffman]

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.

[@shigerufan1]

At 7:05 you can see his laser is a 20W, so it would be 280% on a 5W.

[@campandcook3118]

@@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.

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.

When I took a stained glass course, they told us to use kerosene to clean glass. It works great.

[@PawPawsWorkShop]

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.

[@BillYovino]

@@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 :)

[@PawPawsWorkShop]

To cut the glass you should use oil cutters. The kerosene may act like oil when cutting and then clean with soap and water

@@PawPawsWorkShop I've never used oil, Windex, or soap and water in any of my glass cutting over the years. Strictly kerosene and an old tee shirt.

[@muskokamike127]

@@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.

[@PawPawsWorkShop]

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.

[@skaiser3871]

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

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

[@PawPawsWorkShop]

The process would be the same. The power and feed rates may vary. That will require a little testing.

[@ericdickson2248]

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

[@PawPawsWorkShop]

The white color is the glass itself. It’s normal to see the etching better with the black background

[@jbrunson1949]

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.

[@Brangustx]

Good video, however, ALWAYS burn glass and acrylic engravings from the backside (reverse image). Try it.

[@PawPawsWorkShop]

I have done that several times on acrylic and glass. It is a great technique

[@loriniles6888]

Have you tried tempera paint on tile?

[@PawPawsWorkShop]

No, it is a different process you need the chemicals in the spray paint to work
