Hi all, sorry to have kept you waiting, the Ronin app V1.1.4 adds a joint angle calibration feature. Please see the operation process below to see if it helps.
1. First press the button twice to re-center the gimbal. Then check the joint angle parameters under app’s “Motor Parameter”. If any joint angle value is above 1, or the axis arm drifts after the gimbal is re-centered, then joint angle calibration is needed. Please see the picture below: the pan axis’s joint angle value is bigger than 1, therefore adjusting the pan axis’s joint angle parameter is needed.[view_image]
2. Push and pull the joystick several times to change the axis’s position if its joint angle value is above one or it has drifted. Observe the joint angle data changing in the app and stop operating the joystick after the value is less than one or the drifted axis’s arm is in the centered position.
Perhaps it'd be a good idea for DJI service people to discriminate between users facing the "gimbal not centering properly" from us users facing "gimbal randomly starts drifting", as these might or might not be caused by the same errors
My Ronin S with the latest firmware to date (March 2020):
0. Has a payload of little over 2.7kg (a BMCC plus some unfortunately heavy lens, plus the focus motor).
1. Drifts intermittently, I can't reproduce how or when it starts, but once it does, it will drift on the tilt axis upwards when the joystick is configured on the normal position, and downwards when I have the tilt on reverse (which I usually do) It just does so randomly.
2. I believe I caught a message before in the App (which never saw again) urging me to do a joystick calibration which I recently did, but the problem remains.
Caveat: I think the gimbal starts drifting a little when I use the joystick and then, after a while, it gets worse and worse.
Dear DJI guys: this is gear we rely upon to do our jobs. Please create a better structured response to this problem. Is there a way we can upload console logs to DJI? |
