Thanks for contacting Gudsen Technical Support.
Would you please try to reset the default setting and then do gimbal calibration and check again?
If the problem still exists after your attempts, please provide the below information so that we can follow up on your case further to help you properly.
1. S/N on your gimbal. It's on the device itself, under the quick release system.
2. Video with the described issue.
3. Purchase receipt in PDF or picture.
4. Where are you located now?
Deeply appreciate your cooperation and understanding.
