Thanks! I forgot to take note of these settings. I want to say the speed was around 1300mm/m. It was at 100% power, and 2-3 passes. Antler is very hard, so basically like engraving a hard wood. Hope this helps.
You can certainly create some amazing things with a dremel. A laser is very precise, and gives sharp detail. But you can't carve a 3d object with a laser. Or many other things a dremel can do. But I'm a sucker for buying and trying new tools/technology lol.
