I've ordered new motors.

Been there, done that! I hate it when that happens.

I apologise if I'm going over old ground but I'm new to gimbals,

Been putting together my home made gimbal for a mobius cam using the GLB Alexmoss mini 8bit on 2.4 b7 and Multistar 1807-340kv motors,

Gimbal is pretty well balanced, but I get a high pitch noise when I plug the power in to the gimbal,

Changed the PWM setting to high but it's still there,

What do I need to do to get rid of the noise,

I have the same problem with the 8-bit.

I have the Alexmoss mini 8bit on 2.4 b7 on a CS1 gimbal and now I'm trying to get the shakes out of the gimbal when flying. It's setup to all the recomendations from the CS1 people and not its down the the finishing touches. I'm new to this. My props are balanced on my DJi Phantom 2 and the vibration/shakes come on when off the ground and flying. I'm interested in any suggestions that somebody might have. I already burnt the first controller but now I can use the GUI and reset, etc. without problems.

I am using the 8-bit controller on my 3-axis TRD Beholder Aero gimbal and I have to say I am impressed with the performance I got.

I am too in the process of ironing out some details though.
One of the most annoying phenomena is a violent vibration mostly on the yaw axis that I get at extreme pitch angles +/-45 or more. It starts slowly with a low frequency-small amplitude oscillation and it picks up quickly. After a second or so the gimbal is shaking so violently that the yaw motor cogs to the next position - either to the left or to the right -that happens randomly and it's loosing the center (I am using the gimbal in yaw-follow mode).

This happens both when I tilt the quad and when I manually pitch the camera via R/C. I feels like the initial oscillation is exciting the IMU which is giving back positive feedback to the motor to oscillate faster and so on...

But why does this happen? Why on the yaw axis when the quad or the camera is just tilting on pitch axis? What could I do to fix that?

I am attaching a screen shot of my current settings.

Thank you in advance

Is anyone able to identify this board?

Its 8bit ( atmel328) but appears to have 3rd axis support on board? It also came with a 3rd axis daughter board as well I assume (I didnt buy it, just got handed it all in a bag)

Is the 3rd axis some sort of pass through? How do I wire it up?

Ive put together quite a few 8bit and 32bit basecam systems, but this one has me scratching my head!

Cheers, but that board is different to mine, note the yaw axis pins.

The pins labeled Yaw / Motor are probably connected directly to Yaw motor output. you could measure that. It looks like that that additional board is not maybe designed for that main board, but probably ok to connect.

Just need to follow the connection diagram, you could connect the yaw motor directly to the additional board.

However proceed with your own responsibility. I am just telling what I would do.

This is killing me

Does anyone recognize this issue? I'd run a search on this thread but the issue doesn't lend itself well to being searched. In a nutshell; when I give pitch input to tilt the cam I get unwanted roll. I've notice in several youtube videos that others do this too but to a much lesser extent.

Here is a list of things I've tried so far.

-Adjusted balance (no effect)
-Moved IMU from outside to inside (no effect)
-Accel calibration both 1 and 6 axis calibrations (no effect)
-Adjusted everything I could in the GUI one item at a time and returning it to its previous setting before moving onto the next item (no effect)

Here is a video of the issue:

The last resort for me would be- Try different orientation of the IMU.
