Rocking in poshold mode

I just put it through autotune and it starting rocking. What is wrong here?

This is a 3d printed diy homebuild. I’d like to understand how to read the log better myself. Is there a good youtuber out there that goes through log?. There are in some others (betaflight).

here is a link to my log file.

For some reason after autotune it puts my P very very low. This is the reason it is rocking in the air. What is causing the PID on P to drop so low.

This frame is a home build, with everything 3d printed or made myself. I even made my own dampers. I always fear that this could be an issue. Does it look okay? … running 18 inch props and tiger MN5208-11 340
