Hi All!

So I'm cutting a deer scene piece in some basswood for a charity thing and not long into my finishing toolpath my tapered 1/8" ballnose bit snapped towards the top of the cutting threads. I haven't really cut anything 3d other than a few tests over the years in foam board so as far as feed rates and settings I'm no expert. Hell, I don't even have Aspire (yet)! I did my rough pass with a 1/4" endmill.

Attached is a screenshot of my toolpath setings in Partworks 3d, as well as a picture of the piece being cut and my broken bit. Looking at my settings, am I cutting this too fast?

Do I need to get rid of some of the excess wood around the long edge of my carve? It seems as if when it hits the edge of the cut it wants to take more of the boarder around the carving out with the ballnose bit and maybe because its a deeper cut it is putting too much stress on the ballnose bit? Any advice would be greatly appreciated! TIA.
