Camera gimbal Roll

Posted by Paul Williams on July 28, 2012 at 9:32am

I've just updated to 2.7,

since the update i have a small problem with the camera mount.

Before i could use the CAM_R_TRIM to level the mount, this time it has no affect :-( I tried to set 1700>Wright Params then read and it's accepted the changes but the cam mount has not moved, tried the same with 1300 still nothing.

but it's moving when i roll the quad it stays level and pitch is OK as well.

Any ideas guys?

Regards

Paul.

    Hi Guys.

    I've also got the same issue still with 2.9 release and have adjusted the center roll position the way Brian has mentioned.

    If anyone knows if there is a real fix for this yet can you let us know. 

    Thanks.

    The camera/mount stab is new now. I don't think trim is used. At least it wasn't when I wrote it for planes. It has just been put into copter and there was another unrelated version for roll & pitch. That's all changed to the new full 3d way. There may be some problems. It was working in the plane version. I will look at it .

    I found the same thing. Didn't matter where I set the TRIM value, nothing happened. I asked the same question in the main 2.7 release thread but didn't get an answer there.

    I've modified the servo MIN and MAX values to "pull" the midpoint level.

    From looking at the 2,7 release thread, I think the gimbal parameters have changed to accommodate yaw stab - also there are new params w.r.t software limitation of servo travel. Maybe you should scan through that thread?
