I ran the long, 500C recipe and the system failed in the same way.  The lamps would shut off, the indicated power spikes to 100% and the reported failure is temperature deviation at set point.  I monitored the plate temperatures with the TC's John installed.  There was a big difference in the two plates (82C vs. 42C).  The actual fault maybe the top plate overtemp, but it is not reported this way by the software.  The 85C reading was for T1 (John do you know if it's the top or bottom plate).  The system water flow is <1gmp compared to a target of 2gpm.
