Accel clipping

PX4 Autopilot Multicopter
#1

Hello,

I keep getting the warning ‘Accel 0 clipping, not safe to fly!’ whenever I fly my drone in manual, position, or mission mode. I checked that every part of the body is tied properly, and visually I don’t see any excessive vibration in the body. Also, I’m using damper screws to install the flight controller. Can anybody advise on the issue?

Thanks.

@mnayfeh When the logs are examined, the vibration level seems very high.

visually I don’t see any excessive vibration in the body.

Could you check the autopilot mechanical interface connection on the frame again?

Can you perform the steps I tried to describe below and do a test flight again and share it with us?

  1. Calibrate ACC & GYRO again
  2. Set SDLOG_Mod to 2: from boot until shutdown
  3. Set SDLOG_PROFILE: 19 (0 & 1 & 4 )

Good luck

Can you share a picture of the drone (especially how the autopilot is mounted)?
It seems that the horizontal vibrations are stronger (Y axis is clipping the most), did you balance the propellers?
