Thank you. I'm experiencing this problem right now, so I will step by step go through the suggested tests and settings to help zero in on a better print finish!

I solved my problem of poor dimensional accuracy and over extrusion on the top layers by setting different flow multipliers for the walls and top layer. in my case I changed the wall flow rate until it matched the wall thickness I had set (used calipers to measure the printed wall calibration box). then I used a lower flow value for the top layer to avoid over extrusion, you would do the opposite if there's gaps between the lines
