"unexpected reply from WSXA_DetermineGlobalStageTilts", rejects wafer after P-chuck. We see the standard mark action on the right camera, but nothing on the left camera when wafer reaches E-chuck. Other errors in the logs suggest problems with tilt, leveling, red laser. Next user observes same problems
