    keyword="Reference Cell" position discrepancy

    I noticed that the "allowed positions" for the lifting stepper motor and the actual position is different for the "Reference Cell":

    Allowed Actual
    --------- --------
    #rev -75.0977 -75.0000 Reference Cell

    Typically the actual revolutions are within 0.0001rev of the allowed values. Therefore, the "Reference Cell" might be off by (0.4mm/rev)*0.1rev=0.04mm.
