Yes, I would prefer an SVG. My laser can import vector files directly. It supports G-code, but I've never used that so I don't know how.
Any discoveries to share creating specular holograms using a laser?
I tried clear acrylic, it didn't work... I'm not sure if black acrylic would work better, or if it's the same. But I was using extruded acrylic as it wouldn't frost to white when engraved, and I don't have any extruded black handy.
