Turbulence after corners

Hi team,
Have an issue where there’s shadows or turbulence after the printer turns a corner. Is this a IS or too high accel issue? Are their tests I can run to try and nail down the issue?

VCore4 500
PETG or PLA

What's your PA value? Might need to tune PA again

Also looks like underextrusion as the top surface doesnt look great

its been a few months since i set it up, you're probably right

its a pretty solid infill when the angle isnt like this, and this is only half way through the print and paused. thanks for the tip ill play with it. I think its running 99% extrusion atm as the first layer was terrible and dropping blobs everywhere when on 100%

oh if its only halfway through the print that would explain the top surface

maybe worth to try and dry the filament, you have quite a bit of stringing and some blobs here and there, unlikely to be the cause of the turbulence however

PA best guess
