For some AUTO missions, failsafe needs to be disabled. When the mission prohibits heading towards home from any point (could hit a mountain) or is expected to fly beyond reliable control range. Even…Continue
"if you have a working redundant power supply, (if you can disconnect the 6p DF13 the primary (powermodule) , and pixhawk redumes running)
THEN this is a clear sign of possible software crash, you are running beta - 3.2
If you have power…"
"ok, I guess you still won't believe my conclusion, like before - but what you *actually* can see, it Chan3 drop proportionally to 4, because motor 3 is the opposite motor of 4.
Like I told you, you lost lift on 4, so the opposite motor *must*…"
"ESC's have their own power supply. - they often beep on PWM loss.
PWM goes away when pixhawk loses power. - so they beep. (Pixhawks PWM microcontroller shuts down too)
Redundancy; Pixhawk is able to take up to three different power…"
"no, if all ESC's was out of power/underperforming for any reason, you'd see logs indicate a huge increase in motor PWM and ThrOut.
What you see is attitude get out of control, and the three other motors dropping throttle in order not to…"
"Sorry, I as about to recheck the log, and I must have been looking at wrong log, or failed to see the cause:
Plot ATT.Roll vs ATT.DesRoll - , you'll see a huge error near line 16000
same for ATT.Pitch vs APP.DesPitch ,
"oops, my bad , that conclusion should have been posted on another case, I must have let a browser tab with your case open.
There is no sign of power causing any problems in your log.
In your case, I see no reason for ThrOUT to go low in line…"
"yes, apparently it's possible. :)
There is not much sanitychecking onboard, maybe mostly because people wish for APM still to work, and the space is limited.
on the other hand, some settings are impossible to predict sane values for, like…"
"that's a good catch Bill !
except does not "think it's landed" or "shuts down" - but puts motors at idle (which we could see except for no RCOUT logged) to achieve the incredible vertical speed of 50m/s - and…"
