One Thruster not working

[gcelec]

I’m trying to find out why QGC isn’t sending a command to thruster 3.
ESC and thruster work if connect them to another thruster channel on the Pixhawk.
I swapped out the Pixhawk in case it was a faulty channel but that didn’t fix it.

Is there somewhere in MAVlink Inspector where I can see the commands to each thruster?

Hi!

Check in the MAVLink analyzer the message SERVO_OUTPUT_RAW. If servo3_raw changes, it means it is likely a hardware issue. If it doesn’t, please check the SERVO3_FUNCTION parameter.

Thanks @williangalvani - SERVO_OUTPUT_RAW was reading 0 so went to SERVO3_FUNCTION parameter and saw it wasn’t set to Motor 3.
