Can't calibrate mag Matek M8Q 5883

[MaximMalkov]

I have a problem with calibration of magnitometer Mateksys M8Q 5883 in INAV 3.0. Currently it is CW90FLIP and it finds North properly. But the problem, that I also need to roll it for 21 degrees, as it mounted with the angle. The command align_mag_roll = - 210 does not help, the magnitometer loses North after it.

Mount for the GPS + magnitometer is the following https://www.thingiverse.com/thing:2973323

My current dump is the following:

Could anyone help with this issue

You cannot use the alignment presets together with the manual alignment settings. Try

set align_mag_roll = 210
set align_mag_pitch = 1800
set align_mag_yaw = 900

The last two settings are equivalent to CW90FLIP.

@avsaase thanks a lot! How can I set alignment presets do DEFAULT in INAV 3.0 (in order to use manual alignment settings)? If I would set align_mag = DEFAULT, it will be CW270FLIP. Or should I set set align_mag = CW0?

I made it like this right now, is it right?

set align_mag = CW270FLIP (probably I should do it =CW0)
set align_mag_roll = 210
set align_mag_pitch = 1800
set align_mag_yaw = 900

The Quad finds North correctly right now, but it is rotating a bit in setup.

Iirc setting any of the align_mag_[axis] settings to a non-zero value makes it ignore align_mag. If that is not true then set it to DEFAULT.
