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%
