Stabilising a servo gimbal

#1

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 -> https://github.com/PX4/Devguide/blob/master/en/advanced/gimbal_control.md) 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?
