The current setting is about 3mm off to the north. 2nd time after calibration it actually cut faaaar away from where the microscope was pointing. After the cut it also goes into the Parameter display mode.

Message-ID: Hi! Ilwoong reported a problem to Maurice that the machine resets itself when you use the air gun. Tony Parco just tells me that the machine resets itself in some combinations of using the air gun and doing the rotation between index I and index II... He further says that the spindle stops. Please don't use the air gun for now -- and we'll ask the maintenance fellas to look into this.
