Yeah, I know how to set the skirt distance. It now only touches the part when there is no support around it. If there is support, it goes around the support and ignores the part. Support usually doesn't touch the part so it leaves the part with no brim. This also means setting a solid base layer to the support doesn't work either. Again, it only goes where the support is and doesn't touch the part itself.
The brim should completely surround the part and also the support.
Before someone says to use a raft, I shouldn't have to. Besides, it creates such a course finish.
