I've recently noticed my ronin-s drifting after double-tapping the trigger.  For example, if it's standing on a table and I double-tap the trigger to realign, it aligns put then slowly pans about 2-3 degrees to the left.  I've updated the firmware and attempted a joystick calibration.  Thoughts?

To further add to this...I just figured that if I hold down the trigger, it begins to pan very slowly to the left.

Hi there, sorry to read on this, just to verify, when you press twice the Trigger to re-center the gimbal, it will keep drifting or it recognizes the center point 2-3 degrees to the left, did you try the system calibration? Any chance to show us a short video? Thank you in advance.

Thanks for following up.  Yes, when the trigger is double-tapped, it re-centers then drifts a couple degrees.  Further, if I hold down the trigger it drifts (pans).  Here's a link to a video describing it.

I have this same problem.  Holding down the trigger I experience panning to the left.  Also, setting a user mode with smooth track turned off the gimbal drifts to the left (although not as fast or as far).  I've tried meticulously balancing the gimbal (test shows "excellent" balance).  I do auto tune every time and have even tried calibrating the system and calibrating joystick.  This is making it impossible to do hyperlapses.

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. ID18896-1.png
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.
ID18896-2.png
3. Press and hold the joint angle in the app for about 6 seconds to start the joint angle calibration. Then click “OK”.

Hey, I'm having exactly the same problem, however, my "Joint Angle" isnt about 1, it's 0 to -5. I did try going through these steps but nothing changed at all. Could you please help asap, I have a shoot very soon

I’m having the same issue out of the box. Balanced, auto tuned and balance tested = excellent. The joint angle bandaid works but if you turn off the ronin s you have to go thru all the same process as above. Also, if you recenter the gimbal with a double tap after calibration it does it again. I own a osmo pro and never had an issue. You turn it on and start shooting. This is a hack fix and it’s not a solution

I’m having the exact same issue. With the same results. The fix mindy suggested works temporarily but as soon as I turn off the gimbal or hit the recenter button it starts happening again.

Hi
I am having the same issue.
I have done the joint calibration twice now and as soon as I hit the recenter button it happens again drifting to the left on the pan to 6.6
HELP!

Hi everyone. I was having the same issue with the Ronin S. I might have found a solution. Test it out on your own device and let me know if it works for you as well.
Steps
1. turn on and connect to the ronin from the app on your phone
2. Click on "Configuration"
3. Click "Settings"
4. At the top click on "More"
****Make sure you do NOT have any cables connected to the camera because they might be affected during this.
5. Click on "Balance Test"
6. Recenter the gimbal by clicking the trigger twice.
7. If it still drifts then click on "System Calibration"

This seems to work for me every time. Kind of a pain but better than a drifting gimbal.

Peace

Hi

I'm having the same issue regarding panning. The top part of the Ronin-S moves independently from the grip portion when panning and thus I cannot pan correctly.

I manually balanced the Ronin-S and updated the firmware and my tests come back "Excellent" yet it still sways.

@fans527d8b78 - Wow, many thanks for your workaround! Have my Ronin-S since a few days now and had the same problem. Tested your advice but skipped point 5 (Balance Test). After System Calibration everything worked like a charm, no sway. Best thing, even after shutting down and switching on the Ronin-S a few times the problem is gone!!!

I  tried to do  the offset  calibration. After  it finished,  my Ronin   S  started violently  shaking.   I  turned it on   and off.  Now every  time I  turn it on it just  violently shakes.   I   tried  updating  and  downgrading it,   re-calibrating,  doing  balance  test,  nothing has fixed  it so  far.

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?

I am having the same issue on a brand new Ronin S. The gimbal centers perfectly but then immediately drifts to the left about 12 on the joint angle parameter and stops. Holding the trigger makes is drift again another 12 to 24. It is a very specific issue and I can re-center using the stick and use the gimbal normally. The issue is only when double tapping the trigger to re-center, it centeres perfectly but then drifts 12 to the left and stops.

same issue here. I returned it to the store for repair and DJI simply sends back a message saying there is no issue to be found. After hours of testing, I came to the conclusion it is channel 3 (horizontal axis) which is pushing random values constantly which is making it drift when you put a control on channel #3.

I hope some RONIN S guru knows what is going on here because this is unacceptable. First, my gimbal is gone for 5 weeks only to get sent back with the message 'test ok'. If they did a thorough search for the problem they would've found this.

I cannot seem to edit my post anymore but here is a video of how it looks like.

You can clearly see channel 3 is pushing values when its not even connected to a joystick axis.

Hoping you've found a solution over the last 7 weeks since your post?  My Ronin-S will often and intermittently drift immediately following a double-tap of the trigger.   I've tried absolutely everything suggested here for weeks.  I even upgraded to DJI's latest greatest firmware.   I cannot seem to resolve this.  I'm also starting to ponder if it was ever this unreliable when I'd fallen way behind (but more stable) on an early summer 2019 firmware rev.   

So discouraged.

Hi, Mindy.  

I've tried the Joint Angle Calibration.  It doesn't seem to work.  I'm using the latest app and iOS.
