PETG really really bad (photo)

As you can see, it's not working. Tried just about every trick I know (and could find).

Any suggestions?

yes, #1 your printing too hot. drop 10 deg from where your at now. #2 if your using rectilinear infill which prints every other layer then bump up your infill extrusion width to 140%. this basically extrudes more material so the infill comes out a little cleaner and more solid. it will bridge all those little grids better leaving a cleaner flatter surface for your top layers to be printed on. do both of these and things should be better. if you still need improvement then lower 5 deg at a time and do a test print until its right.
