Hello everyone, I have Ronin SC about 6 months. The gimbal rotates uncontrollably

I use the gimbal with:

Sony a6400

Sigma 16mm f1.4

Sigma 30mm f1.4

Sigma 56mm f1.4

From the beginning I have problem with the 16mm, gimbal can't handle the camera with this lens properly, the gimbal has small shakes from Tilt and Roll motors.

After 2 months of using it the gimbal starts with small vibrations on the Pan motor. In 4 hours operation it vibrates like 4 times.

And now the Pan motor can’t totally handle the camera with any lens.

The gimbal is perfectly balanced on all the motors.

All the calibrations from the phone app are done.
