You inspired me!!!!
The first one did not go well. I ended up finding some screws loose.

mine came out fine.  I think I want it bigger and maybe another step per mm but otherwise came out great on the first try.  500 mm/min speed and full power with black primer spray paint.

1. Was this etched with the rotary attachment?
2. Paint on inside or outside of glass?
3. Paint removal method?

I had the opposite problem today.  My screws were too tight and I broke the post  that connects the chuck to the stepper.   I glued it but I need to print a new one now.

paint outside
yes on rotary
goof off and a paper towl

Looks great Nottingham

Paint on the outside
Yes on rotary
Washed off with water (I used Apple Barrel black paint that is $0.50 from Walmart. )

I just started printing the fixture. What plastics did you make yours with? So many addictions, so little time!!

There is a craft fair Nov 4th at the local Veterans house. I have downloaded logos for Army, Navy, Marines, Air Force & Coast Guard. Currently scaling to fit the slate coaster.

I used PLA. As mine has not broke (like someone we know...... ;)), I will suggest PLA.

I used around 30-50% infill depending on the parts (whether load bearing or not)

I have PLA & ABS. I tend to ignore anything by anyone with promoting laser etching slate. We all know that is pure fiction. Where is that Michaels order???

Why do I always feel miserable after looking at your success??? My wife saw some earlier glass postings and bought me a case of wine glasses, some simple vases, and canning jars. She parked them on my etching raw materials shelf and keeps asking about my forward progress on the rotary tool.

Very impressive, especially considering these lasers "won't engrave glass"  ;D

Wow guys, nice work ! Could you tell the rest of us the exact process ? You paint the glass with something, then laser it, clean it and done ?
Thanks, keep it up.

That's the quick overview. I have tried about 10 times with varying degrees of success. Critical parameters:

   1. Paint type - tried 5, 3 did nothing.
   2. Paint thickness - too thin just evaporates the paint, too thick doesn't heat the glass.

6 attempts have just removed paint. Did not touch the glass. 2 were so so, 2 came out pretty good.

Starting a more rigorous evaluation procedure using "standard" test patterns on flat glass. Also switching from 1.6W to 2.4E laser.

What paint types worked ? Could you post a link ? I will try to find something simillar here in Europe, it's going to be a pain in the a**.

Black primer did nothing for me. Perhaps applied too thin or too thick.

Post by: ThothLoki on February 06, 2018, 02:09:18 PM
Might be that the 1.6w laser does not heat up the glass fast enough before the paint gets blasted away. Try your 2.5w and see if it different

I belong to a club that has a show in 2 weeks and I was planning on running both the core-xy and the glass etcher. Half afraid to swap lasers today and mess everything up but swapping lasers is definitely part of the test plan. Got some different flat black primer tonight and will try again.

You are also the root cause of much of my compulsive obsessive socially deviant laser etching behavior.

Don't forget Loki. He is the one that started this whole glass fad.

Hi

Have someone experimenting using a milling tool in a rotary setup for engraving glass?

When I get my rotary tool from china I will try it out  :)

I use a small rotary table. Will post pictures when camera comes out of hiding.

I have been trying to post pictures of my entry in the wine glass etching game. Each time it fails with an error code of 500. Individual pictures are about 1.2MB.

Try my resizer in my signature line.

They might be too large (pixels not MB)

@thorloki - Thanks but I don't have JRE installed and am ready to reload the base system so I just tried resizing in  gimp. Went to about 1/4 scale. Will try again to post.

Third attempt to post some picture of my entry in the wine glass etching game.

I use a low cost rotary table with a 3D printed spring loaded chuck. The prongs push outwards from the inside of the glass. The advantage of holding the glass vertical is it does not require support at the far end. The disadvantage of this design is I need a few different sized chucks depending on diameter of the glass.

The vertical (Y) axis is 8mm rods and a 4 start 8mm lead-screw. As pictured there are 4 linear bearings. The original design had just two but made considerable noise at certain speeds (600 mm/min). Have since learned that the bearings need to be worked in, especially with the cheap 8mm rods I bought.
