I have a Ronin SC with a GH5 and Olympus 12-40mm. I've had intermittent issues calibrating the lens when using the DJI focus motor. Sometimes the motors calibrate normally. However, many times (usually at the worst possible moment) what happens is it will do its calibration to close focus, then stop abruptly, and the light will flash yellow without completeing the calibration process.
I tried downgrading the firmware, cleaning out the connectors and it still does it every so often. I've had this gimbal for a couple years and it's only started doing it in the last few months. Any ideas on what could be wrong?
