I always wondered if it would make sense to do an alternative way of making perimeters, which will not stop and start at the outside perimeter. Let me explain what I have in mind in a picture:
In this mode, the shell of an object would be (at least) 2 perimeters, and it would only stop and start on the INNER perimeter. So it will start on the inner perimeter, then somewhere along the line swoop to the outer and print the outer perimeter but instead of stopping at the end, it will swoop back to the inner perimeter, and finish that. Then the start and stop point do not have to be at the outer perimeter, which could give a smoother result for the outside of the object, specifically for bowden setups.
I haven’t seen it in other slicers myself, but I might have missed that option, or it might have been tried but not working. I would be interested to see this as an alternative to increase the quality of the outer perimeter and get rid of those blobs at the end/start of a perimeter.
