There has been much talk of this in other topics however I’m not finding a CLEAR answer and I think that is because there are so many different types of metals and hardnesses. I would love to see a definitive list of metals a Glowforge 40W can etch, cut or engrave and whether Cermark can be successfully used to do so if it’s not possible to engrave on the bare metal. Also what depths or thickness will be…
Some of these like copper are kind of a no-brainier. Here’s my list. Feel free to add to it.
