Here are some thoughts kind of in an order.
Temps at 230 for ABS.
Make sure to measure the filament diameter over some distance and enter the average in the slicer.
Try extrusion multiplier at 1 for now. You can run some calibration tests to dial it in.
Start with rectilinear infill for now.
Uncheck “external perimeters first”
Set “gaps” speed to 5 or 10 or 0 for off but a low number.
Reduce infill/perimeter overlap to about 25% and see how that is.
I would set the extrusion width to a number rather than “auto” or “default” generally the nozzle size or 1.2 times the size so for a .4 nozzle use .4 or .42. I use .45 on one of mine with slic3r.
Try turning off “extra perimeters” and “detect thin wall” and see how that does. Seems the extra perimeter setting caused me an issue once.
