I decided to give S3D another chance given all the enhancements in V3 and re-bought it today. The product is maturing and seems to be moving in a good direction. So, I pulled up one of my latest projects and worked through a custom config for my Rostock Max (aftermarket hotend, electronics, etc). Things went well and I was able to transfer a lot of my knowledge with other slicers to S3D. The first part printed but there are a couple of issues to work on. The first is - and I see others have posted here about this - the top layer is very, very rough. Surprisingly rough. I'll do some more research and experiments on this one. The other seems to be a slicing artifact and is odd and may be contributing to some of the roughness. Here's a screen capture of the first layer with the issue annotated with yellow arrows:
As you can see, at what should be a simple corner, the second perimeter in makes an odd "dovetail" path. The top one might make sense since the outer perimeter is disjoint at the corner but the lower one is next to a continuous perimeter. Quite odd. Has anyone seen this and have any suggestions to work around or resolve it?
