Gimbal offset more then 10 degrees

[NadivM]

Hi all,
I have replaced my mavic 2 pro gimbal after a crash.
New gimbal after turn on calibration has a 45 deg offset in yaw and 6 deg offset in roll.
I tried manual calibration gets stuck on 20%.
tried IMU calib and MAG calib didnt help.
the offset manual fix in the app is up to 10 deg for each axis .
tride the hack with calib via computer with the github code-I ruind main gimbal boards that are stuck in boot mode.
Did anyone see this problem befor? someone maby know how to fix it?
Help pleas

Download and Install Python on a PC.
Download and install DJI tools
JointCoarse will move the gimbal to its extremities and record the values
LinearHall will then centre and level the camera between the extremities discovered.

Tools .
1. Download Python
2. pyserial
3. GitHub - o-gs/dji-firmware-tools: Tools for handling firmwares of DJI products, with focus on quadcopters.


GUIDE :
1. Download all tools
2. Install python
3. extract pyserial and dji tools to C:\DJI\
4. Open "command prompt" as administrator
cd C:\DJI\dji-firmware-tools-master

Thanks for the suggestion
I have tried it
It shows as if it is doing the calib but it ruind my gimbal board I replace 3 of them, every bord that I tride to calibrate stoped working, it wont do calibration on wake up or torque the motors

I don't see how DJI Tools can ruin a board. It simply sends instructions to the drone to start certain onboard functions.
Anyhow; How much of the gimbal did you disassemble?
It sounds like there is a faulty connection.
There are six delicate connections between the main board and the camera.
More likely from the movement you have described, if there is a fault, its one of the 4 connections between the main board and the PTZ connection to the gimbal board.

I don't know if this helps (probably not) but I have noticed that when calibrating a gimbal, it is the roll motion which starts at 20%.

good luck
