hi,
after updating firmware to 2.40b7, my yaw 3rd axis board produce oscillating(vibrations). i never have this problem before. i have the L6234 version 3rd axis extension board.
now the camera is all time shaking if 3rd axis motor is connected.
after updating from 2.3b5 i noticed that my gimbal tilt totally. so i decide to reset the controller board and start configure from beginning. i completely adjust all pid and power settings new. also all other settings. after two hours of adjusting pid's and power settings, pitch and roll axis working great. but yaw axis is all time oscillating a little bit.

my procedure to find good values.
first i reduce yaw p & d to zero and set power to 130 and 0. i set I to 0.03.
than i start increasing p step by step. if i reach p = 3 motor begin to work. p3 produce small low oscillations. so i increase D step by step. at D = 5 oscillation are gone. but with p = 3 yaw axis power is to low for good working with rc and also in windy env. it is only good to stabilise the camera with ideal conditions on desktop. so i have to increase power for yaw axis.
but now, if i increase power( i try both P settings and/or power settings) the yaw axis begin to oscillate. P=10 and power 130 are strong enough. to hold the gimbal in wind and more heavy flight movements. but with this power settings it is impossible to terminate oscillation. i increase D step by step. there is no point without any oscillation as i know from older firmware. increasing d from 7 to 8 switch from low oscillation to fast oscillation. :(.

my current and best yaw settings are P=10, I=0.03, D=7. Power = 130. no extra power. but this settings are really not good. yaw axis power is now nearly twice time reduced than with old 2.3b5 firmware. also yaw oscillation is there.

any ideas.
thx
