Quite frustrating that I can't independently control feature speeds, particularly inner perimeter, outer perimeter and distinguishing solid layer fill speed from infill speed.

I am printing carbon filled nylon that seems to have too much extrusion friction. As a result, I need to print small features very slowly (e.g. 300mm/min) but I can print infill (both solid layer and infill layer) at ~1200mm/s

I can get an acceptable behavior with solid layers by setting default speed to 300mm/s and setting solid infill underspeed to 400%, but in this case, when transitioning to non-solid layers, the infill reverts to 300mm/s.

You can already control the speed of the perimeters, internal infill, outer solid fill, supports, etc. They can all be controlled separately.

So if you need the top fill to have a different speed than the internal infill, you can already do that
