Compass calibration - bad fit, using previous
#1
In the Pypilot calibration app I've performed the following steps:

- IMU heel pitch calibration: OK
- Accelerometer: Turned the IMU on 6 axes until green dots came on every side of the sphere and then locked the calibration
- Compass: Sailed out and turned the ship a few sharp rounds in a rolly/wavy condition, but then I got the following notification:

Bad fit, using previous setting. After that I locked the calibration for the moment, but I could see on the sphere that is animated in the calibration tool that the green dot or lines that then are projected, would not fit the entire circle outline. At one corner of the sphere it did not fully "fill" the sphere. So it looked more like an oval on one side.

Don't know what the mistake is, could this be because deviation and that I have a steel boat?
Any way, I made 3 circles while calibration was not locked and I even cleared the previous setting. Before I can "rely" on the autopilot I guess I need to first finish proper calibration, but I don't know how to do it correctly, or maybe it is already correct?

Looking forward to any opinion or knowledge on the matter.
