Another issue is just setting your extrusion width to auto or some other predefined number you have settled on. If you have a 1 mm thick wall in your model and your extrusion width is set to 0.48 then you are going to have issues. If you set your extrusion width to 0.5 then you in theroy have the ideal printing condition.
