I’m printing ABS on a mini.
I’m using large brims and most parts come out pretty decent.
Parts with curved over-hangs are not good.
Sloped overhangs are fine.
The feature in the following image is a cylinder with rounded ends.
The upper half has the correct shape but something happened with the support material.

Here the feature that failed is a sweeping curve and again there was a gap between the support material and part.
Structure Type: Lines
Distance x/y: 1.5
Distance z: 0.15
The distance values are the defaults.
