The DJI Ronin is one heck of a gimbal, and one of it's stand out features would be the Auto Tuning Software. Well for anyone using SBGC Basecam Alexmos Controllers with their gimbals, the new firmware now offers an 'Auto PID' feature as well. But before you get too excited you may want to take a look at this video demonstration.
So the new firmware offers an amazing set of new features, and Auto PID tuning seems to work. This still doesn't solve the other areas that you need to be familiar with including sensor position, sensor calibrations, gyro calibrations, and motor configurations. Before you can use any of the Auto PID features, you need to properly configure those settings first and balance your camera properly on the gimbal frame.
I've heard some people talk about how everything works except for the 'Pitch' or maybe the 'YAW' is buzzing. Using the Auto PID tuning feature with one axis may now quickly solve these issues. Keep in mind that with a sliding scale between Better Stabilization and Better Precision your results could vary. Even though it's 'Auto' there's still a fair amount of trial and error that can be time consuming to use this process.
If you're working with 32 Bit Gimbals like the CAME-TV 7000/7500 (found here) or the Varavon Birdycam2 (found here), the new firmware should be compatible, but you know what they say. 'If it ain't broke, don't fix it'. If you have your gimbal working well, there may be no real reason to upgrade the firmware at this time.
