Update: I found out that my motor to frame gearing ratio in fact wasn't 0.6 but 1.6 (I was working with the frame to motor ratio) but still have the same problem. The encoders calibration of el field results in the error message.
Update: Now I read that the "Angle to move at calibration" should be set to 40 After resetting this angle the roll axis calibration seem to work. But when it changes to Pitch it is interrupted.
