Trying to configure servo to AUX1/2, not getting expected result

We have formerly used the ardupilot flight stack to configure a servo into ports aux 1&2. Now that we have graduated to PX4, we are testing similar functions to see if this platform will work for our intended uses. We are running into some trouble. We have a gripper that we are trying to function via aux port 1 or 2, and when we map our RC, we are able to monitor and observe different values being send to the flight controller, but with no results. Given the fact that we have observed our inputs working I am confused as to why the gripper isn’t actually receiving any input from the flight controller. Would appreciate any input.


Is the mixer set up correctly? Do you press the safety switch so that the servos are armed?

Yes both criteria have met met
