Running latest beta MP 1.3.39 1.1.6068.13300 on Win 10 with ardupilot quad X v3.4-rc2
Just tested the onboard mag calibration routine, which starts just fine - the sliders in MP for Mag1 and Mag2 move across to show to collection of calibration points. The slider for Mag2 however makes it to the end of the scale fastest, and as soon as it reaches the end, a popup appears witgh the message “the command failed to execute”.
I presume this is a MP issue. Need to try the same in other GS software.
