Stabilising a servo gimbal

Hi, im using px4 1.8.0 at PX4_FMU_v2, Im trying to figure out how to stabilize a simple 1-axis (Pitch) servo gimbal using MNT params, but without success…

Here is my Params:

I tried to use custom mixes inside my fs/sdcard/etc/mixers (as shown here → PX4-Devguide/ at master · PX4/PX4-Devguide · GitHub) without sucess too.

My servo is responding when i use pwm test -c 1 -d /dev/pwm_output1 -p 1100 at system shell.

What im doing wrong?

Hi Mainardi,

may try to MNT_MODE_IN to RC. In AUTO you need a large Stick Motion to react.

We also use a servo for PITCH Control. But i have the issue, that PWM is changing his value to lowest, when Pitch-Servo reach maximum end position in stabilizing mode. Vice versa same, PWM is changing to maximum, when Pitch-Servo reach minimum end position. In ROLL Control we do not have this problem.

Does anyone knows this effect and heve a solution for it?
