Looking good! The chess pieces look great! I wish I had a printer that could do that.
You might want to increase your pass depth on the outer part. I don’t have my machine built yet so I don’t know for sure. Endmills are designed to have a cutting edge up the whole spiral unlike a drill bit. Every pass you do at 1mm deep only puts ware on the bottom 1mm of your bit and the cutting edges on the bottom of the endmill. So when that wares out and you think the bit is toast, the whole upper part above that 1mm is still good. Deeper cuts with slower feed rates might help or they could end up burning the wood. Just a thought. It really takes experimentation with each machine, material, and bit to get it all perfect.
