I am a compete newbie, just set up my GF Plus yesterday. I did get to etch and cut on some birchwood plywood and now I am wondering what settings I can use to etch some black aluminum business cards.
How did these turn out? and if they did what setting did you use on your Glowforge I bought the same cards awhile back and never did anything with them yet, but will now, I know they work on a diode laser form a friend of mine as he showed that it works, so must on the GF, let me know what you did…
I just picked up a 50 pack of the blue (double sided!) cards from Amazon. 700/full, 270 dpi. I took a hint and first rendered an outline onto some plywood scrap, then used double stick tape to hold it into place in the outline, and then rendered the image on the card. Would have been perfect, but the forge did not want to go as fast that close to the side as my registration cut was, so I moved it manually for this test and missed a bit - so my picture is a bit too far to the left. Still, happy with the first sample and the product as well.
If you’re going to make more (but not in bulk), you could put a pencil mark on the lower lip of the crumb tray, and cut an “L” shape jig out of your scrap that aligns to it for repeatability when you want to print one.
You don’t need to tape these down, they’re not going to blow away.
