Yup. The coating is either bleached or it isn’t. If you want shades, it would need to be convert to dots to simulate shades. This works better for things that you look at from further away versus staring at 2” away.
Has anyone here tried the Inventables anodized aluminum? About to give it a shot, but wonder if anyone has any cut settings recommendations?
I noticed tat Glowforge advertises that anodized aluminum can only be engraved, but I’m still curious as to whether anyone has tried to cut it? Or knows a reason why it’s a bad idea to try? Seems like if it fails to get all the way through, there good guidelines for cutting on another tool at least?
Thanks for all the helpful posts everyone! I really appreciate the resource this community provides.
The GF does not have anywhere near enough power to make the slightest mark on bare metal. All you can do is burn (etch) away anodizing (which is just a surface dye) or mark with a coating. Even the term “engraving” is misleading when working on metal, no material is removed.
Cannot cut aluminum with the Glowforge. I have good luck engraving anodized aluminum with 700/50/350, but you should test a small area since I don’t know how intricate your design is. I was engraving text. There are lots of posts about aluminum if you search the forum.
