Camping on the Roof

Aww, I miss my xterra! Couldn’t justify bringing it across the pond. So much space for art materials/projects…

Looks great. Thanks for sharing. Lots of slate roofs around here in New England. Shortly after I ordered my Glowforge, we was at an architectural salvage store and I grabbed 10 slate shingles. I can see lots of possibilities.

We have a couple of pieces of slate from a 200-year-old roof that we use as cheese boards. We use a piece a very hard chalk to write the name of each cheese that we are serving. I have a feeling that our cheeseboard is about to get more ornate.

Nice! Pet memorials is another possible use.

Hard to see any problems with your test. That is amazing on a material that really doesn’t get used as a lasering medium.

No. You can’t even feel the engrave above. It’s more of a bleaching effect. I used far more power on a piece of slate like tile my first week and was able to get a mark that you could get your fingernail into. But not much more.

We have three of them. The wife uses hers as a portable art studio and camping vehiicle. A pickup with 4WD would work as well in these hills but can’t throw my upright bass in an open truck bed. The one I drive lost the transmission yesterday at about 210K. Praying that I can flush it as a quick fix. Otherwise, will be going online to find a reasonable 2015.

Seems like we are going to have a near-limitless variety of materials to experiment with, once we all get our units of course :wink:

That contrast seems much greater than what I got, do you recall the settings?

The settings, as you know, don’t mean a lot on the low end right now. Engrave 5%/335/270

This was the original drawing:

Real slate reacted a lot differently than another man made material on the left. The octagonal tile that I originally thought was slate had a dark, almost melting look to the lines with the same settings.

I am jealous of your box of slate. I love the material so much, I restore old burial grounds that are filled with the wonderful slate stones and just took a class on how to carve slate in hopes of eventually learning to repair them. Slate is one of the first things besides wood I’m putting in my GF.

Thanks.
That other material sure looks like slate. maybe be a ceramic. The mineral content must be a factor also, the slate I did @50% 335 340 isn’t nearly that white.

Of course if a material doesn’t engrave as expected, there is always spray paiint.

I THINK the tile I found was slate, and it went pretty deep. They were rasters, though:

Yes. What I see on yours is consistent with what I saw on the octagonal tile when I used a much higher power. This pic was from a microscope. All of the pictures so far in this topic were raster engraves.

Curious: are raster engraves more powerful than vector lines, even if the same power and speed settings are used?

We may be having another misunderstanding with the terminology. When I say that I used line drawings, I was talking about my wife physically drawing pencil lines in the original artwork. That artwork was then engraved as a raster file. All of the pictures above including yours were engraved in a raster fashion, not following a vector path point to point. But to answer your question, I don’t know how the percentage of power translates. Right now, we know that the 1%-5% power selected for an engrave is significantly higher that those numbers would suggest. It seems to be artificially limited until the next update. Don’t know whether that translates to 5% or 50%. All of my scores go significantly deeper in all materials than engraves.

That’s a great test!

@rpegg, If you could find, buy or make a slate cutter then you can have those really fancy beveled edges and cut down the slate to what ever size you need. I’ve included pics for a slate cutter and some slate that I cut to size before I carved and painted them.
