Hi all,
After last flight with my Copter (Cube Orange and Here 3), i looked in the Log Analyzer and there is a Compass WARN because of high Offsets in two Axis.
The Copter is a Little bit nervous after some flighttime in hovering with Loiter Mode.
Can anyone give me some support what is the Problem?
Thanks

Can you post the log?
It’s hard to tell without the complete log

I have had a look at your log.
All of the mag (except MagZ on Mag1) has a periodic interference.
I can’t see the RCOUT values from the log
But I noticed that the roll and pitch are inversely proportional to the mag interference pattern. And yaw is directly proportional.
You may want to go through the CompassMot calibration to eliminate the interference from motors.
Hi Alvin,
thanks for your Support. I will make the Calibration when the Weather will be better and give a Feedback later.
Regards
Hi Alvin,
i have done the CompassMot Calibration. Here is the Link to the Flight Log. The High Offsets are still in LogAnalyzer. The Interference is now at 13%, i think ist okay now. Why are the Offsets so high?

Can you show a picture of your setup?
Are you placing the external compass far enough from the high power electronics?
Hi Alvin,
here is a picture of my Setup.
Thanks

Can you try to disable the internal compass in orange cube, by setting the compass mask parameter, and see if anything improved?
I think you may be experiencing the same/similar problem with heater-mag problem. You may have a look at these discussion at the same time:
Ok thanks, sorry for the confusion, and for the magfield it is normal that it fluctuates a lot once the heater is completed warming up. This doesn’t make much sense to me due to amperes law.

Hello,
a while a ago I had a crash with my copter* and my Cube Baseboard got damaged. I replaced it and repaired the Here GPS antenna (the case). The Cube itself looks undamaged.
Today I went out for some test flights but I always got a bad compass and no arm.
After recalibrating the compass it worked 1-2 times and I was able to fly a small mission. After unplug/replug the battery same issue. I could only solve it by compass calib but not all the time. It was quite cold today so maybe tempera…
Hi Alvin,
i will try it. But in my first config, the internal Compass was disabled and i had the same Compass “WARN” or “FAIL” with High Offsets in the Log.
I will Comeback with results.
Thanks

Can you share a screenshot about it?
