I want to control actuator without arming but px4 not letting me to do that as per px4 default settings. Is there any way I can run my actuator and check it if it’s working or not before flying???
By default PX4 locks outputs until armed, so you can’t just drive actuators “live”. For bench testing, use QGC → Actuators tab (you can move each servo/motor without arming), or set CBRK_IO_SAFETY / CBRK_ACTUATOR for temporary bypass. Just remember to put them back before flying — those circuit breakers disable safety checks.
Check this page. We have a “pre-arm” concept that allows you to move servos before arming (though not motors).
