Hi,

have had the Ronin S for a week and works well as long as you don't move much.

Please refer to the video link below. Sorry about the focus, was in a hurry.  

Camera is balanced very well and autotune performed. When I swing/rotate to the right (anticlockwise) the motors vibrate badly and sometimes all the motors loses control.
I have waisted hours trying different balances and app settings. Gimbal has the latest firmware.

Has anyone else having the same issues? Is there a fix?

Hi QEdit, sorry for the difficulties on operating the Ronin-S, the video is not available, could you please upload again?
Did you try the Auto Tune? If the issue persists, may I have a screenshot of the Motor Parameters and Advanced Settings? Thank you.

Sorry Mindy I had the permissions on the video set incorrectly (I'm old school). The video link should work now.

Before I shot the video I did perform a Auto Tune and the parameters were all +- 1

Sorry, no solution here but I've got the exact same issue as in your video. Received my Ronin-S two days ago and tried several lens setups with my GH5.
Carefully balanced it every time and also updated the FW to latest release - problem still persists.

Maybe an issue with the latest wave of the Ronin-S?

Mine does the exact same thing. Tilting it sideways makes the motors rumble hard. I've balanced it perfectly and I've run all the auto tune and calibrations.

Hi all, this issue may occur when the axis is rotated to its limit, we will get it optimized in the future firmware, sorry for the inconvenience caused and appreciate your patience.

Thanks for recording and posting it here. I am facing the same issue and thought I am doing something wrong.

if you're trying to transition from high to low or low to high, you don't do it sideways. This is where gimbal lock occurs. The Ronin-S was designed to be transitioned front to back and holding the trigger. You would also never shoot anything at that angle. There's nothing wrong with your Ronin-S as the current firmware makes them all behave this way.

had the same issue, and I'm worrying that gimbal can kill my lens or camera. My lens already received some kicks from gimbal

Thanks all for replying to my original post.  

As DJI-Paul says, it seems that it’s normal for the gimbal to do this… Normal?

Being an Electronics Engineer from way back (when computers ran on steam)  I can see now that the problem is not with the mechanics but with the software.  It shouldn’t matter what angle a properly balanced gimbal is on the motors and control systems shouldn’t get ‘confused’.  In this day and age this sort of tolerance is NOT acceptable.

Lets hope that the software (firmware) guys can fix this bug PROMPTLY before someones camera and or gimbal suffers serious damage. Looks like Mikex gear has already had some knocks.

I would be careful plugging a monitor or audio cable into the camera as it could get ripped out when the gimbal ‘loses it’.

Looking forward to the bug being fixed in the next firmware release.

Same issue here. The gimbal sits perfectly still when turned off at this angle. Turn the motor on and shakes

I've had a similar problem I noticed since day one of having my gimbal. It isn't just moving high to low, it is just turning/rotating it sideways that does it also. Also underslung mode has a problem where you can no longer adjust its tilt at a certain point. Will try to take video when I have time.

Sorry Mindy but I'm sure that many users would not find that an acceptable answer. Please refer once again to post in #10.

Going by the amount of replies to the original post this is potentially a big problem.

If you can’t  endeavour to fix the issue in future updates, perhaps you should publish warnings to advise users that the gimbal may perform severe movements and or become unstable if rotated anti-clockwise”

… or something to that effect.

Hi QEdit, I understand your concern, the issue will be forwarded to our engineers for attention, we will keep optimizing our product, please note our website about the future firmware update, thank you.

Hi Qedit, have you tried plugging your camera into the GH5 with the supplied USB-C cable?  I'm curious to know if you are seeing the same problems that many of us are seeing when our GH5/GH5s is plugged into the Ronin.  Especially if you also have an external HDMI monitor connected.  Be aware that many of us are seeing borderline violent behavior when the Ronin goes out of control.  But we are also seeing our motors go limp, buttons don't work, focus randomly doesn't work, etc.  It doesn't happen all the time, but it does happen.  (My Ronin totally went out of control on a shoot yesterday, in front of the client).

If you DO find that your Ronin acts up when plugged into the GH5, please update this post with more info.  Also consider adding GH5 to the title of this thread so we can more easily distinguish GH5 owners who are having issues.  Thanks Q

Sorry Mabou2,  I only have a GH4 at this time. I'm waiting for the new Blackmagic camera.

But I have the Ronin spin out of control many times during shoots, luckily the lens has escaped damage but I can't say the same about my audio and monitor cables been ripped out and the gimbal crashing into the end-stops.

As all of us have reported that our gimbals have been balanced correctly therefore it MUST be the software (firmware) that is the problem.  There are bugs in the code that cause the gimbal to become unstable when certain values (states) are reported by the sensors and by the motors (position).  These should not be torque related in a balanced gimbal.  If the software guys have dealt with these sort of bugs in their other gimbals, then they should be able to debug the algorithms in Ronin S.  

Hopefully they make this a priority before selling or shipping any more units and release an upgrade.

Hello again,  just noticed the firmware update (blind camera man).  Hopefully it addresses some of the concerns above.

DJI Paul, whenever you respond to a support conversation your input seems defensive.  There is never anything wrong with the gimbal, and it seems like you are usually pointing to user error.  When people post serious issues for which nobody at DJI has a good answer, you are nowhere to be found.  I'm sorry for being so blunt, as my intention is not to insult you.  It is just my observation.

Help!

I received my Ronin S after months of waiting. I balanced it, did the firmware update and begun to get used to operating it! When I would try attempt to go under slung it would go crazy. Spinning out and then vibrate like mad! Now, it’s not working. The battery is on, the focus pull works (connected to Gh5) but I have no power in the motors... please help!

I have somewhat of the same problem, except mines spins out of control as soon as I turn it on. All 3 axis are balanced excellent according to the balance test. Please help!

Hi guys,

Facing Ronin-S motor issues too.

Have already updated the firmware etc. When it's switched on, the machine will tilt up on it's own. When we double-tapped the button to reset it, it won't respond. It will only reset after we adjusted the joystick. The gimbal will also tilt non-stop, even after we have stop adjusting the joystick and it also can't be reseted. Have already sent repair request to DJI via email but hardly no reply.

Please help! Thanks!

Hello. I got my Ronin S about a month ago, and after some time of using it, it started turning off/sleep the motors when randomly while on use. Then I updated the firmware and it seemed to have been fine for a couple of days, then suddenly it won't even work anymore. The motors are up but no response.
This is really frustrating.
