Re: Shutdown epi2 SNF 2008-10-17 12:48:19: overpressure error during big etch

Adjusted the throttle valve PID at 600 Torr. Ran the Big Etch recipe with no problem.
Chamber intermittently has a difficult time controlling pressure around 600 Torr. Might still need to optimize the pressure control response.
