You can try the solution I described here (edit your axis_twist_compensation.py and do manual calibration by 30 points, maybe even automatic will work with this fix).
I described it a month ago, but it was ignored…
Also more details:
The problem is that with the current axis_twist_compensation.py code, the calibration points from the section
[axis_twist_compensation]
#*# z_compensations
y_compensations
are shifted by 2, i.e. they are not applied to the coordinates that were measured during calibration.
The problem is in the uneven magnetic properties of the PEI plates (I have the same problem on 3 of the 4 plates - areas (bands) where the cartographer gives incorrect readings. Although axis_twist_compensation is not designed to correct this defect, its operating principle allows it to be compensated.
