Roll doesn't stay level in follow mode when turning left or right.

    Roll doesn't stay level in follow mode when turning left or right.

    I have start degree to 90 and mix at 0.

    My roll won't stay level, shifts to a Dutch angle and then after 1 minute levels back out until I turn again.

    Please help!!!

    i have similar problem
    in follow mode, with a 3xis setup, the Roll angle tends to tilt some degrees, just 3 to 7 degrees, to left or right depending by direction I'm turning the gimbal
    if i manually shift the YAW, as shown in the videos about how to tuning the alexmos board, i can clearly see that the Yaw affects the Roll in a direct way...

    one more thing, I tryed to use the OFFSET values in the Follow Mode menu but it has absolutely no effect, also with big numbers...

    this happens undependandtly if I use the ESTIMATE FRAME ANGLES FROM MOTORS or not
    I mounted also a new IMU, I did different IMU calibrations...nothing changed

    all this started to happen when I introduced the YAW axis, when I had only the pitch and roll all was working pretty well

    any way to fix this? how many people have the same problem?

    increase the P on Roll
  • anaka
    will do

    thanks

    Hi there I have the same problem, did not find the solution. Can you tell us if you got it working properly after increasing P on the roll ?

    Same problem here too but I manage to the tuning a bit better with firmware 2.4 b7. Last time I tried increasing the "P" on the roll axis, even a small amount made it completely unstable. I couldn't fix it with "D" or "I" either.

    I'm going to have another go at tuning it now. If I can improve jot I will post what I have done.
  • kikojiu
    set follow mode to 40- 20
  • anaka
    increasing the P on Roll works...I did it only on the Hand Gimbal

    in the next days will try the same approach on the flying gimbal and will post my impressions

    Hey kikojiu, what do you mean by 40- 20?

  • kikojiu
    the degrees in follow mode

    Maintaining level horizon question: does using roll follow mode help hold the horizon level for normal APV flying ?
  • Garug
    What is APV flying?

    But if you have your camera/gimbal system installed to any airframe, the answer is no as the roll would be following the airframe and the airframe is not steady horizontally.

    Sorry, I just use APV abbreviation for Aerial Photography and Video. Thanks for the confirmation, I just saw a lot of comments about follow roll that must all have been referring to handheld gimbal use....

    The 40 - 20 tricks did the job for me on Held Held rig.
    Thanks Kikojiu.
  • anaka
    hi kikojiu
    i'm not using the roll follow but just the yaw follow...
    and in that case increasing P made the things a bit better but when I turn the frame to left and right I still can see some influence on the roll
    any idea on how to fix it?
    thanks for all your help ;)

    I'm having this exact issue as well on my 3axis. When I yaw a full 360, gimbal will begin to roll, then level out and roll the other direction throughout the range of the 360 turn.

    Same problem here, I got 2 x 3 axis gimbal, both having same problem. But one gimbal I can manage to solve.I place the sensor upside down and change z to -z it's works. But for another gimbal not possible to place sensor upside down, so I still trying out. No solution. If anyone know pls tell me, above suggestions are not work for me.
  • NYANA_Myanmar
    It's all about sensor not aligned and I haven't do ACC CALI. After I do proper ACC CALI according to the GUI instructions , all OK. Nice! and Happy.
