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.

As more people begin taking the challenge of building their own 3 Axis Gimbal Stabilizer, there have been numerous questions with still little information. One popular question relates to calibrating the IMU sensor. In this video I attempt to show my method of performing the 6 Point Calibration of the IMU sensor and why I choose to do it this way.

Unlike using a cardboard box, this method using a Leveling Cube ensures you can visibly see how level you are before performing calibration. It also allows the sensor to remain completely flat across the cube.

If you look closely, you can see that laying the sensor down over the exposed solder pins may cause inaccurate results. Perform your calibration with the sensor level using only the flat area. Hopefully this bit of information has been helpful and may allow you to get slightly more accurate results from your 6 Point IMU Calibration.

At first I thought these cubes were merely a novelty item, but after working with these gimbals, I have found so many more uses for them. They are great for checking how level your gimbal is when placed on a stand while balancing your camera. They are also great for checking the level of your camera immediately after powering up your gimbal (make sure your horizon is level before shooting). Great little item to have around for just under $2.50 + Free Shipping, I suggest grabbing the cubes with 3 bubble levels built in (click here)
