Reducing the max volumetric speed (MVS from here on) in the filament settings will cause bambu studio to limit speeds in other settings that are greater than the filament can handle.
Some people think that the high fluidity of the Meta means it’s a high speed filament, but this is not true. Using any default PLA settings will probably have a MVS that’s too high.
This post explains how to calculate the MVS, with the info most manufacturers give. Click to read the whole post.
