    Are the filters found in the "basic" tuning screen Gyro filters or Output filters or a third filter kind? And what´s the workflow? Try with the "basic" filters first and if that does not help, tamper with the "advanced" filters?



    There are two kinds. Output and Gyro. If you have looked at the charts I shared with you before, last section indicates "Output filters and gyro filter can generally be used interchangeably. Here is a test to prove that.".

    If you set the Output filter to 1, then you get to change the independent ones (ones in the basic screen). Values above 1 override the independent ones and sets them all to same value.

    Independent filtering is really important if you look at the other charts. Tilt is usually mechanically much stiffer than other axis, so it doesn't require much filtering as pan does.




    To get the best out of tuning, here is a suggested workflow:

    Setup
    • Set Gyro filter to minimum, as output + gyro ~= total filter. This way you can start seeing responses from lowest filtering.
    • Set Output filter to 2, so it controls all axis (less work during experiment).
    Repeat
    • Autotune (70% is good. Doesn't matter much during this data collection as long as you use the same value through out)
    • Write down the stiffness values you get from autotune for each axis.
    • Change Output filter. If you want extra fidelity, increase by 1. If you want to finish this faster, increase more.

    Usually you never need filter values more than 20. So you can stop there. Now look at each axis, and see what filter values resulted in most stiffness value. Set the Output filter back to 1 so you can put independent ones.

    For example if you got best on pan with Output filter set to 12, then it would mean 13 (+ 1 from gyro) total is good for pan. In this case you could have:
    • Pan output filter at 8 and gyro at 5 = 13, or
    • Pan output filter at 12 and gyro at 1 = 13, or
    • Pan output filter at 3 and gyro at 10 = 13, etc
    I personally put gyro filter on the higher end. For instance if tilt needed the lowest and needed 5 total, then I would set gyro at 4, and do calculations for independent output filters from there.

    MōVI Pro does all this for us now! Such a time saver.
