Who else thinks Cura should have an infill thickness option? It seems to only be one line thick and I think it could be printed at a higher speed if only the thickness of it could be set like the walls, top and bottom can have their thickness set.
I can print walls at 200mm/s, but I seem to have to print the infill at 30mm/s or maybe even slightly slower. A little thicker and I think I could print the infill at 200mm/s.
If you wanted higher speed infill, choose an infill pattern with less changes in direction.
So you aren’t accelerating and decelerating the whole time.
Having a higher extruder RPM like you suggested would wreak havoc on infill above overhangs.
You mean like above the hole in a hollow cube?
For example. The shell layer spanning the gap will not be able to support much weight at that time and the infill will sink in instead of supporting itself.
Has anyone tried a circular infill pattern to remove the need for direction reversals?
When reversing direction is not the only time you will not get enough filament. Going from a slow region to a fast region will cause it too. The reason is that after filament reaches the hot zone, it has to heat up before it will squirt out the nozzle. I have not seen a setting for compensating for that in a slicer yet.
+Nathaniel Stempel we are talking about changing direction in the XY-plane and thus accelerating and decelerating a moving mass. Not changing the direction of the extruder stepper.

@Marcus_Wolschon Yeah. I was talking about xy position too. What I meant about the extruder was not reversing direction. When you r xy movement is slow, the extruder runs slow. When the xy movement is fast, the extruder needs to be fast. There is a delay between the time that filament is fed to the extruder and when it actually comes out the other side. That is because the filament expands inside the hotend. Due to that delay, you can’t simply switch from slow printing to fast printing because the filament would not be squirting out of the hotend soon enough. Any attempts to switch from slow print to fast print will probably result in under-extrusion during the fast printing period.
