I'm using v3.0.2 and totally love it, but I have a consistent problem with the top surface being marked by the nozzle. This is true on my MakerBot 2X, Ultimaker 2 and Dremel Idea Builder. I have gone through the Print Quality Guide and the forums with no solution. I always enter the exact filament diameter, have messed with the extrusion multiplier and tried the z-lift settings with no luck. This is frustrating as I can get clean top surfaces using the default software for any of the printers.

Any feedback on this?

You need to add a little z lift. In the layer tab its retraction vertical lift. Set that to 0.2. It will lift that amount during travel moves

If you are using the Z-lift properly, then there's no way you would see those marks. So either you need to increase the lift value or you don't have it setup correctly.
