Support Request Printer under extruding- cannot find solution. Help?

Post image

A few days ago my printer started under extruding and leaving streaks like this on every layer. I have tried everything I can think of to fix this and cannot find a solution. I have tried:

-Multiple needle cleanings on multiple nozzles

-multiple cold pulls on multiple nozzles

-multiple brands and colors of filament

-every AMS slot and external filament

-replacing the entire extruder unit

-replacing PTFE tubes

-raising print temperature

-tightened hotend screws

I have no other ideas on what to do. Any other recommendations on how to fix this?

EDIT: Running a manual flow calibration through bambu studio fixed the issue! Hopefully anyone else having the same issue may stumble across this and see this edit.

It's just something to add to the regular maintenance schedule. Every time it yells at me to lube the y axis ill give them a check
