This is in response to problem/shutoff posted on 2008/12/04 17:25.
Problem location: When facing the SVG coater (coater module), the belt farther away comes off the "rotors/pulley things". This is most noticeable on the three left wheels. The problem seems to be that the left most wheel is about 1/4" off mount. When looking at the other left most wheel on the other track, the bolt is flush with the wheel. This is not the case on track 2 and causes the belt to shift off the other wheels upon use. 
The problem does not disable the track; the track is still useable. But it may break soon; or wafers may end up getting stuck in the future.
