ABS prints are coming out terrible

[DBFIU]

I don't believe this has anything to do with bed temperature, but rather the bumpy or blistery texture of the vertical shells.

In my experience, those bumps are usually from infill moves or priming, causing material to flow out past the exterior perimeter.

Corrections include printing slower, doing fewer pulses of prime/unprime, and/or adding more vertical shells (perimeters).

I will try all these methods. The part is thin, so I might not be able to add so much shells anyway since the thickness of the material is a little over a millimeter.
