Hello, I am having a problem with rotating motors and I need your help.
I purchased holybro s500 v2 which comes with pixhawk6c and px4 software.
I constructed the frame and did the setup, but when I try Motors Setup on QGroundControl, only motor4(M4) rotates and the other 3 motors do not respond.
Here is what I did for debugging
I checked the voltage on PDB
there was no problem
I plug in and out the PWM wire(black and white one) on motors
when I plug in, all the motor make the correct sound, which means that motors are not dead and connections are being established.
I switched the PWM wires between motor3 and motor4
only motor4 rotates when I test on motors setup page, which means that the signal is reaching the pins for motor3.
I armed the drone with manual mode
only motor4 rotates, so it’s not a bug with Motors Setup page
This is where I am stuck.
It seems like motors are ok in terms of hardware and signal and power are also working. However, 3 of the motors do not rotate.
One concern is that in Airframe, I can only find holybro s500 and not holybro s500 v2, but I am not sure this can be the cause.
Thanks for your help.
