    33   * Start the DMI pipeline with cycle time of 10 seconds (This should already be
    44     running if you are on trajectory).
    55   * Start the DMI metrology loop (this will set the DMI focus point).
    6       NOTE: The DMI focus point is the distance where the focus will be held if you activate the DMI metrology loop.
