The calibration corner is 0 value, left panel is Z axis and right one is X axis. Under Settings > Advanced settings > HardwareSetup there are Left and Right Calibration Panels and
you can rotate them rot_x, rot_y, rot_z. If you know the the angle value btw. your object and left Panel then you can rotate your coordinate system so that an object is alligned with
the x,y,z axes. I hope I wrote this one correctly, if I am not then someone please revise this
