Slow infill printing speeds
With my latest print I am getting slow infill printing speeds, I don't know how long this may have been happening as it's been a while since infill timing really mattered. I am using the default 0.2mm SPEED profile for the CORE One (infill speed 300mm/s) but the slicer is maxing out the infill print speed at ~100mm/s. The perimeter walls right next to the infill are printing at their 250mm/s speeds just fine and I can't for the life of me figure out which setting/configuration would be slowing down the infill specifically. (See the picture)
I have tried:
- switching to the MK4S system preset, same issue.
- switching to different "Print settings" presets, "SPEED" vs "STRUCTURAL" and layer height don't seem to effect anything significantly.
- switching filament type (PETG, PLA, ASA, etc.), the exact infill speed DOES change, but is still slower than the perimeter walls.
- switching from grid infill to other infills, aligned rectilinear gives a faster speed, but none of them reach even the perimeter speed.
- changing infill density, no effect.
If anyone has any insight, much appreciated.

In case anyone in the future has the same question, I found out the limiting factor! The max crossing infill speed on the Generic PETG profile was set to 110mm/s. (Filaments > Advanced > Max crossing infill speed)
Raising that limit increased the speed up to the max volume flow rate.
