Photos on Marble

Postby Dustin Hawkinson » Sun Dec 18, 2016 2:47 pm

I gave black marble a try last night. I used Gimp to crop and prep the images, then used RDWorks to "handle" the bitmap (png exported from gimp). Luckily I thought to order a third marble tile just for testing and was able to try different settings and dial in the parameters. I only used about 6 watts at 400mm/s for the scan of the bitmap. I thought they came out pretty well for a newbie's first time attempting a bmp scan.

I did mess up the text placement though. RDWorks crashed on me right as I had it all set up the first time and I had to start over :oops:

I have ordered some black marble to try 305mmx305mm
I think your photos need unsharp mask in phototoshop or in gimp.

Keith - I'll have to pick some up from Lowes, pretty cheap. I bought this stuff online from Lasersketch already beveled and ready to go as I wanted to make them as a gift.

Alexis - I'll try unsharp next time. I used 18% power.

Attention black marble does not like to stay outside without sun protection (acid rain), for gravestones use granite got better, very good work

Thanks for the feedback Peirre. These are small 6" x 6" tiles that will be displayed indoors. I hope to try granite as well sometime.

Dustin those look pretty good.
I too have been trying to figure out my settings on marble. Tile on right was my old machine before it burned up.
Tile on left I am trying to get right as I had It saved in previous machine and did not write it down. I have since learned to write it down.
I used your settings on the top right in the left tile and went at 5 watts on the lower right in left tile.
Yesterday was one year since my mother passed away. The whole family is gathering at her grave side Saturday and I would like to have something at least temporary to leave there.
Thanks Pierre for the advise, I will look into granite for a more lasting photo in the future.
Thanks for posting some good stuff.
Hopefully I can help more as I learn more.
BTW, the second picture is a couple crosses I lasered the other day.

Lookin good Willy. Have you considered making the background behind your mother black? It's a little easier to fade into the natural marble that way. Personal preference of course.

I'm definitely going to revisit marble soon again and try granite.
