Hi there, may I verify the off-center you mentioned means the gimbal will drift out of center or it will not center when you control the gimbal to the center point? More details will be appreciated.
I'm having the same issue as OP. It seems as though the Ronin S loses the horizon after being used for a few minutes and the roll axis ends up tilting to the right or left.
This only became an issue AFTER I upgraded to the latest firmware.
What’s happening is as I shoot with it the gimbal loses its center point. It doesn’t return to center on its own. Double trigger resets it obviously. In my opinion it should always return to center.
I have two gimbals and my Zhiyun crane doesn’t do this.
The gimbal should not drift at all. Mine centers when double triggering but just drifts a lot as you use it. It’s balanced etc.
