That looks great for 2D engraving setups. Or for cutting parts out of sheet wood/plastic/metal. But based on the videos, I don't think this is suitable for 5-ax

That looks great for 2D engraving setups. Or for cutting parts out of sheet wood/plastic/metal. But based on the videos, I don't think this is suitable for 5-axis milling yet. Also, in the video where you cut out the circular logo coin: https://youtu.be/mGd7EIkCK3g?feature=shared&t=108 https://youtu.be/mGd7EIkCK3g?feature=shared&t=108 it looks to me like you're using a metal cutter bit (with corncob grinding surface) on wood. You might get a lot less burr (that furry stuff on the sides of cuts) by using an asymmetric one-blade bit. They look weird, but they'll cut the wood fibers with a carbide blade instead of trying to rub them off with diamond fragments. You usually want separate tiny chips coming off the material. If it starts stringing - like in the video - then usually it's either the wrong bit or too fast spindle speed (and material melting rather than cutting).
