I just joined the club of the Anonymous Tarot t2d owners...
This post has been very helpful indeed. Unfortunately not to get my gimbal to operate consistently, but to not feel alone, and to get some imput about how to get the damn thing to work.
So, here is what I have:
At first, the gimbal seemed to work OK. Gopro 3+ on it, stable like a rock. Could control both angles externally, like expected.
Then I connected a liveview cable to the camera, and it did not stabilize at all. I searched and found that the plug/cable throw the gimbal off-balance enough to prevent it from stabilizing. So I started playing with every single parameter I can change, but never got it to work consistently. Mind you, I was not even flying the thing (it is on an F550, btw; Powering it with its own 3s lipo, directly. I know this could be an issue, and I find that quite outrageous, to be honest. Tarot can do better than that! Just include the BEC on the controller...), it was just sitting on my desk and swinging all over the place!
I gave up on the liveview for the moment, but now even without that cable hooked up it does not stabilize as well anymore as before. In general it seems to sit quite well (no vibration), but when I either tilt the drone or change the camera angle from my rc it starts jerking around or jump to a random position. It finds back occasionally in most cases. When I change the tilt from my rc it looks like at certain angles, always the same ones, it starts shaking. If I make it past those angles it is stable again.
So, what this makes me think is that the culprit is the sensor cable, going to the controller. If I move that cable then I can get the gimbal to shake, and in some cases stop it from shaking. This is consistent with the problems I have when mounting the liveview cable. Has anybody noticed the same thing?
It seems to me that the thing is so underpowered (or whatever does this) that even the slightest thing gets it off-balance, and then the gain parameters are suddenly wrong. With the cables of course this may mean that the gain parameters would have to depend on the angle(s) of the camera.
What I have also noticed is that some times the gimbal behaves differently when connected to the computer than when I disconnect it (with an outrageously flimsy and unreliable plug, btw).
Has anybody experienced these issues as well?
(btw - I am frustrated by the non-working thing right now, hence the tone. In all I believe the gimbal delivers, considering the price. There is a reason why other devices cost so much more. One useful, and probably simple, thing to add would be, for example, a self-learning PID. These things exist for other devices, and it would make our lives so much simpler! It could be programmed directly onto the controller, or in the software. All the user has to do is press a button and the thing optimizes itself...)
