After troubleshooting with Gary and Mahnaz we came to the conclusion that either the computer has died or there is a problem with power distribution to the computer.

So I tried a few different things and there is actually no problem with the power cable. It's actually the power supply that's defective. The power supply has about 5 circuit breakers which provide power to different components of the unit. The one that's attached to the computer and the Vortex unit does not work, in fact it was continually cycling off and on so I went ahead and shut it off to protect the Vortex unit. When I plugged in the computer cable to a different circuit, the computer worked fine. Furthermore the connections in the back of the unit don't correspond to the items that they should be plugged into. While this does not effect the performance of the machine, it made a little bit difficult to diagnose the problem, but I'll go over these issues with you tomorrow.

Since the nozzle going off center seems to be a recurring problem, then incorporating the check and adjustment into the training might reduce the occurence.

Had to restart the EVG items in the service menu. Ran 4 wafers without a problem, but when I went to change the syringe to acetone for clean up, the manual syringe down stopped after 1 sec, and syringe would not go up or down using the green buttons. Restarted the EVG items in the service menu, and then syringe worked again. Ran dummy dispense and dried the line. It might save the next user time if you restart the EVG items in the service menu before running wafers.
