One of the biggest challenges of using a laser is learning how each material reacts. Natural materials like wood and rocks are all different. Even the same type material can have huge differences in density that can cause the same settings to come out differently.
I thought I would give thin natural wood cork a try. While I think the engraving came out perfect, the cutting was a major disaster. The cork burned and charred so badly that it made a mess to work with. Although trying any less power and it wouldn’t cut through. I think these would be great if I could find a way to cut them out without burring the edges.
Disclaimer, I’ve used the Aperture Science one a wee bit. 🙂
