overextrusion on top layers

I am running a 3.0 500.
I have tuned the extrusion rate and perimeters are spot on at 0.7mm with a 0.6mm nozzle on Bondtech LGX and Rapido hotend. PA is set at 0.05. Material is MatterHakers ABS. Using PrusaSlicer with the following settings: Topfill pattern: Aligned Rectilinear Top solid infill: 80mm/s Default extrusion width: 0.7mm Top solid infill: 0.6mm Infill/perimeters overlap: 15%

doesnt look like overextrusion to me more like a temp cooling issue maybe how does your spare infill looks like?

I'll have to check. Since this is ABS I generally don't have much cooling going on. Though with Magigoo really holding the part down I could probably try it. That will be a tomorrow task. Along with all the other monkeys the circus let loose in the lab. 😛 Found the issue. With Prusaslicer, in the Print Settings: Advance tab. I had placed values in the extrusion width area to manually define pretty much everything. After stripping out all but the Default extrusion width (set at 0.5mm for my 0.4mm nozzle) everything is back to normal. Not sure why it made such a mess of things. 😕
