Is there any information on Engraving on River Rocks, should I paint it first? I need help on this.
Depends on the rock. Why not throw a couple in and run some tests?
A quick search on the forum for “river rock” yields this:
Take a minute to try the search yourself, you’ll find a lot of help already here, faster than asking for a whole new thread.
You generally get better results the darker the mineral, more contrast.
Here are the settings I used to engrave on grey river rocks. Maybe they will offer a place to start?
Good luck! Please share pics if you get it to work.
Welcome to the forum!
Thank You, did you use tape or paint or just plain rock?
I did not tape it or paint it. I just lasered on plain rock.
I removed the bed, used a few boards to figure out the correct height, used autofocus, and hit print. The flatter the surface the better.
@PrintToLaser is correct. I’ve had the best luck using darker colored rocks.
Thank You, I will post pictures
Looking forward to pictures.
Some rocks engrave well, others don’t.
Paint the ones that don’t!
Also take care when watching the engrave, laser on rock can make for a very bright spot almost like a welder.
