PWM slots not powering ESCs (1, 4, 7, 8)

Drone noob, first time poster, so let me know if this belongs in a different category.

I am rebuilding a Holybro X500.

I have gone through all of the setup, and motors 1 and 4 would not bind to their respective PWM slots, or be detected (make noise) when the battery is connected.

I got around this by binding motors 1 and 4 to PWM slots 5 and 6, but for some reason the other PWM slots (1,4,7,8) do not give output. Is this a voltage regulator problem?

Thanks

Which PX4 version are you using? Or maybe ArduPilot? And how are you configuring these outputs?

I’ve flashed the latest PX4 firmware onto my Pixhawk 6c. Latest version of QGC. Attempting to configure via QGC, binding motors to PWM outputs and calibrating ESCs via QGC.

Have you tried FMU and IO ports? Which ones are working which ones aren’t?
