So I'm printing the Eclipson Model A Fus1 part. This is a thin walled design, 0.4mm or 0.8mm thick walls. Regular slicing wasn't producing the best of results, probably mechanical and tuning issues are adding to the difficulties. I turned on vase mode and got much better results but I was surprised to see that it would run the outer perimeter in one direction and then run the inner perimeter in the opposite direction. It's been a long time (and another slicing program) since I have printed a vase but I recall them simply running the perimeters in the same direction. I assume this is normal for S3D? I'm guessing the design of the part has a lot to do with as I know vase mode is typically used with 100% solid models.
It's leaving a small mark where it shifts from the outside perimeter to the inside perimeter which is a slight annoyance but I can likely clear that away with a little effort.
Just an observation.
