Subject: Problem AG4100 SNF 2011-05-13 09:29:34: poor wafer handling (receive cassette)
Message-ID: <mailman.415.1356280413.3183.ag4100-pcs@snf.stanford.edu>

Put the first wafer in slot 25 and shook the cassette quite a bit.  The second wafer went into the cassette, came back out with the robot arm, and dropped out of the cassette.

Initially, robot crashed into my wafer in the send cassette.  Elmer homed the robot which helped on the send side.  The calibration is off on the receive side (shakes the receive cassette quite a bit in slot 25 and I don't have enough confidence in it to try another slot).
