I've noticed quality issues when printing something like a solid cube. The bottom and sides look great, but when the printer starts to fill in the top of the cube, printing over top of the infill, it's moving at the same speed as the walls printed at, which is causing adhesion issues, especially where the top layer meets walls - if there is not sufficient infill near the edge, the head will basically extrude a loop over open air, and the top layer will have gaps.

If there were a way to have the printer slow down when printing directly over top of infill, similar to how the first layer can be slowed down, I think the problem could be alleviated.

There is! The "solid infill underspeed" option on the Other tab adjusts the speed only for the top layers. So you can easily slow down those layers if you need to without affecting the infill or perimeter speeds.

Oh, odd. I always read that as the speed to print solid infill. Will that also slow the speed for a solid layer over top of supports?
