If you change the camera head it becomes a nightmare. I have one that I can't get. If you have the same head and just repacace an arm. you must mark where the nuts are with a magic marker. Don't touch the ones you don't change. Then you just have to tweak the one. You can replace the ribbon cable without removing the nuts. The nuts have a magnetic north. the camera head is where the info is stored and no 2 seem to adjust the same.
I changed the camera head of one just now and I am kind of lost. I know I have to calibrate every magnet now, but do I also have to use the magnets and boards from the old gimbal?

I have a gimbal that works perfectly but it doesnt give out any image, and the I have another one that is broken but the sensor does work. So I want to install the sensor from this one into the one that doesnt give any image. Im just lost on what I have to do. Thank you

In my humble opinion I would repair the broken one as the magnets are probably set correctly. I have just changed the camera head and it was a nightmare. You can leave the esc boards and magnetic nuts in place but they will not be set correctly for that head. All 3 have to be correct. I did it but it took me a week. I did the yaw first then the roll then the pitch. By the time I got it right I had no hair left. I would much rather replace the yaw arm or the roll. In that case all you have to do is mark where the nuts are before you start. Take photos of then with the mark.

Yeah the problem is that the broken one was already disassembled by the customer so I dont have the magnets in the positions. Yeah its been a real nightmare until now.
Do you have any pointers for me? From what i have read for the yaw you just have to make it align with drone position that it shows on the app, so that the are both pointing at the same direction. And I do have it like that. But with the roll and pitch I am kind of lost. What can I use a guide?

I have seen in the app some alerts of the roll movement limit reached, when the roll arm is at a level position so I guess its still bad. With the pitch I am just seeing the pitch indicator on the app but im not sure thats a good indicator as it sometimes moves when I move the roll axis. If you have any pointers I would really appreciate it.

Thank you

Not really. Once the yaw is point straight ahead it is a matter of getting the other 2 close to correct and then tweaking them. It has been a while sense I tried to do it. can you put up a video of how it is doing right now?
