Compass calibration - bad fit, using previous

[rastam4n]

it appears you have significant magnetic distortion.  Any metal that a magnet attracts near the sensors?

Hi Sean, 

Yes, the metal of the RPi itself.... I must have the IMU too close to the RPi (on top of plastic case).... I'll move it 6 inches away and re-try

This is what I did, I mounted the Pi4 and cooling fan etc and used jumper wires to connect to my Moiteissier Hat. which is mounted about 6 inches away, there is still a small amount of magnetic interference but it calibrates fine, Just my offset is not aligned as well going south
