    keyword=Target - laser half waveplate motion fixed

    8:40 ~ 9:20 am, disconnected stepper motor for laser half waveplate motion, then
    turned its power off. With power off, half waveplates can be moved by hand. So
    we moved them to the IN position, aligned them with low laser power (4W).

    Then power for motor was turned on, cable was connected, IOC was rebooted
    from downstairs (Kathy). Piotr tested it from counting house 3 times (IN<->OUT)
    and left it in OUT position.

    Found edges of half waveplates are dirty, probablly because the mounts were burned
    by laser when there was problem with half waveplates control. Cleaned with acetone.
