PI_TranslationStage.cpp: In member function 'double PI_TranslationStage::correctRelativeMove(int, double)':
PI_TranslationStage.cpp:962: error: invalid use of member (did you forget the '&' ?)

Hier der Code dazu:

double newposition =  correctRangeMinMax(currentPosition + move,
                                             device()->limitPositionExperimental().metric.min,
                                             device()->limitPositionExperimental().metric.max);
    return newposition - position;
