Fix All Microvibrations in your Tarot T-2D

Microvibrations appear as a small ripple in the BGC control-monitoring software trending screens. These are caused be an incorrectly configured torque parameter in most BGCs such as the Martinez and I believe also the AlexMos BGCs. This is not a PID loop tuning issue.......
As an example the Martinez BGC allows user to adjust output torque control to each axis motor.
When set too low, the camera fails to get to the assigned position.
When set too high, the camera tends to jitter as you describe here.
When set just right, you most likely will not be able to see any jitter whatsoever.
Some call the jitter condition an unresolved deadband issue.... a little extra deadband is what makes the jitter disappear.
No need to make it more complicated than it needs to be - IMHO.

The issue with the Tarot gimbal is not related to settings of any kind. The stock electronics are flawed to where no power or PID settings will fix the vibrations. If you have the power output set so low it cannot stabilize the camera it still vibrates. By adding a second board the problem disappears. Probably due to an issue distributing power within the board.
