Gimbal Yaw Arm replacement - calibration steps not working

[Tails275]

Hoping you guys can help!

I've recently repaired a snapped gimbal yaw arm that occurred due to a crash. The camera itself and cables remained intact and the camera feed worked.

After repairing I noticed the camera was off centre and does not seem to be responding to my attempts at manual control using the remote or in app calibration functions (automatic fails, and I cannot make changes in manual gimbal calibration mode).

I've ran the python calibration steps using:

py comm_og_service_tool.py --port com3 WM231 GimbalCalib JointCoarse
py comm_og_service_tool.py --port com3 WM231 GimbalCalib LinearHall

I noticed that the JointCoarse command worked, making the gimbal move around. However, running the LinearHall command has no effect and the gimbal does not move at all.

What other steps can I try, and is it likely that the cables are damaged?

Hey thanks for replying.

Yes this is the guide I followed. The python commands I’ve listed are the ones used in this video.

The first command (joint coarse) worked fine, the gimbal moved freely.

The second command (Linear Hall) does not work, the gimbal does not move at all.

then you still have an obstruction OR more likely a bad cable

I repair a lot of DJI drones. The signal cable can look fine but be bad. Generally, if there was any stress to the gimbal, in your case, the broken yaw arm, it is reasonable to suspect a bad signal ptz cable. Im assuming you replaced the yaw axis motor as well because you are talking about the flashing failing. Ill bet the camera is cocked off to the left isn't it? I don't think Ive ever had the Linear Hall step work. If flashing works, which half the time is doesnt, then it always works fine after JointCourse for me. You can accomplish flashing on www.drone-hacks.com website. It is way easier but can take about 10 minutes. If all 3 axis' of the gimbal moved when you tried to flash it, I doubt the signal cable is bad.
