Hi,

I've got 2 gimbals: DYS for Nex under copter and one large DSLR handheld. Both are well ballanced and tuned [both with 32bit controller with 2x IMU]. And both got same problem: when they stay on idle on my desk they got some light vibrations on pitch motor. If I calm those pitch motors (by blocking them by in my hand) the vibrations are gone. But as soon as I set them free it's starting all over again. I was trying diffrent PID's but those self-vibrations are always occuring. All IMUs got ferrite rings on cables. Any clue?
