Thrusters not working when ROV is armed

We are having trouble getting out thrusters to start up when our ROV is armed. Joystick is enabled and ROV has worked in the past. We have calibrated everything, including the motors. QGC is fully updated, and everything else seems to be up to date. We’re not too sure on where to go from here to get these thruster running when the ROV is armed. Any suggestions?

Hi @ruthduncan, welcome to the forum :slight_smile:

For the thrusters to suddenly stop working seems odd. A few questions:

  1. Does each thruster still do all 5 beeps on startup? If not, do they at least do the first 3?
  2. Can you check the SERVO_OUTPUT_RAW values from the MAVLink Inspector?
  3. Have you applied a custom frame, or run any code that may have changed the motor functionality assignments (e.g. for controlling thrusters individually)? If so it may be worth resetting the parameters.
