FWIW Tackling the Hungry Robot project, I was getting pretty ugly cylinder walls. After printing about 30 cylinders, I finally figured out what was causing all the cylinder wall terribleness (scarring/banding). For me it came down to 2 settings: 1. Compensate wall overlaps (must disable). This had only been enabled for inner wall overlaps, but I found several forums that pointed at this being sketchy. 2. Line width (Marlin recommends between 1.05 and 1.2 nozzle diameter). I upped mine from 0.4mm to 0.44mm and noticed instant improvement. Things that were tried and had no effect: * Outer walls before inner (leaving this disabled) * Coasting on/off (leaving this enabled) * Linear advance (leaving this at K=0.8 now that i went through all the trouble to calibrate) * Outer wall flow (4% lower than flow) * Z-seam (just dictates where the ugliness happened) Perhaps relevant settings: * Combing mode (not in skin) * Retract before outer wall (enabled) * Outer wall wipe distance (0.4mm) David
