Simplify3D User Forum

Hello, this may be a noobish question, but I am printing circular forms and I want perfect rings. Even with wall thickness cranked, simplify really wants to print the center of the ring with a very aggressive zigzag pattern rather than one smooth circle. Is this possible to change? It just makes the top edge look atrocious...

It looks like the Preview Mode was set to Movement Speed coloring here so I am not totally sure what the infill there is. It looks like probably Solid Layer Fill but could also be Gap Fill... Could you please post a Factory File so we can look into this a little more?
