I have a benchtop test rig to test the motors and ECSs. I tried using the sliders in the QGroundControl. I tested with both PWM and DShot1200. In both of the protocols, motors run individually, but if I try to run all 4 at once using the “All” slider, only one of them runs, not the other three.
Why that might be the case?
I’m using Pixhawk 4. QGC v4.1.4. PX4 v1.12.0
