Calibrate Level Error: The Command Failed to Execute

Calibrate Level Error: The Command Failed to Execute

Getting close to having my first Arduplane setup complete using Matek F405 board. One more issue: I did the Accelerometer Calibration before the board was installed in the plane. Now that it is installed and wired the level is off and I want to reset it. However when I hit Calibrate Level on the Mission Planner Accel Calibration page I get the message “Error. The Command Failed to Execute”. Not such a helpful error message. Anybody have any idea what I can try?

Is your plane armed? If so disarm then try again

Any luck in that topic ?
