I saw on your video, you were engraving a design on a mac book, that’s some kind of aluminum (correct me if I’m wrong), I was wondering what other metals will the GF able to engrave.
Dan it also would be nice to have a full list of materials GF is able to work with.
Someone (not GF) here posted a comparison between the two, and there were a few differences in depth of coloration and power settings, but for the money - moly would get my vote…
