Gimbal tuning tutorial

In the following weeks I will be doing some gimbal tuning tutorial videos, the goal is to keep each video shorter than 5 minutes. These videos will introduce new BaseCam 32 bit firmware 2.59 with much improved auto tuning and many other new features. Note though, the used FW is still beta and already known that some parts will be updated before final release.

The purpose of these videos is to assist anyone tuning a BaseCam 32bit gimbal from the scratch.

You can find me at
BaseCam forum with alias Garug, what I often notice when supporting people is that shortcuts have been made on basic setup, on these videos I try to address this by giving a straight forward step by step process. I hope you find the tutorial videos helpful.

If you have comments, questions or suggestions, please contact me via the

Note: On LeViteZer gimbals, the basic setup has been been performed and you just need to do the balancing of the gimbal when changing lens or camera and auto tuning + maybe adjusting the RC and Follow parameters for your specific needs.

1. Gimbal introduction - introducing the LeViteZer prototype gimbal used on making these videos.



2. Basic tuning part 1, Gimbal construction and balancing - if the gimbal construction is not ok, it will never work well.



2.1 Big configuration change from big and heavy 300 mm FD lens to small and light 17 mm MTF lens. This requires complete balancing of the gimbal and different parameters. The parameters are pre-tuned, the big lens on profile 5 and the small lens on profile 1. The LeViteZer joystick controls the profiles. Normally if changing to about similar lens, only pitch axis balancing is needed.



3. Installing BaseCam User Interface and Drivers

Note: Not mentioned on video, but you may be instructed to instal some Java components like JDK, just follow the instructions in such case.



4. Saving settings and Upgrading Firmware - always use the corresponding firmware and graphical user interface.



5. Basic tuning part 2 - IMU orientation, 1 point calibration and motor parameters.

It looks erratic at the end, but never mind, this is just one step and there is still many before the gimbal is working perfectly.



6. First PID tuning from factory defaults.

It did not go quite perfect, but shows how to recover if PID tuning fails. This is now first tuning. When the gimbal is well setup, the tuning will work reliably when changing camera/lens and pretend parameters can be stored to profiles like in 2.1.

Note: Tuning from 0 values is being addressed before the final release of the firmware.



7. Activating frame IMU and second PID tuning.

The gimbal is starting to work great and Auto PID tuning from current values takes just couple of minutes and provides good result.



To follow

8. IMU calibration.

9. RC control setup

The LeViteZer joystick is connected via SBUS and used on this setup. You could setup a normal RC radio similar.



10. Big lens on small gimbal

a long lens on a small gimbal, effectively 690 mm lens handheld.

Setting up the gimbal



Some test shots. This kind of setup would benefice from encoder setup, providing more power. It was quite windy and there was some shakes when wind hit the lens. At effectively 690 mm focal length even smallest shakes show, but I am pretty happy for the result. Ps. operating this lens handheld without gimbal provides nothing usable. That makes also focusing a bit difficult. Electrical remote focus would be very good on this kind of setup.




11. Encoder gimbal, Aerial gimbal, advanced settings TBD... stay tuned.
