Does anyone have an idea what might cause this on overhang sections. Doing ABS at 240.

If this is an overhang, then it needs support. Support mars the surface area some, but prevents this hanging look.

Thanks, that did help, but I also discovered the source of the issue: the non-running extruder of the two was bumping the print. Didn’t notice at first. There was just enough external buildup that it was brushing each layer. Only the overhangs we getting aggravated by it. Easy fix and thanks for replying!
