The power supply for CO2 X laser was fixed (thanks Ed) so I was able to check the operational status of the laser table. The chillers had once again tripped from the PZT control loop sending to high of a value to the chiller setpoints. I disabled integrator, reset the history on the control loop, and restarted the chillers. Everything appeared to be in order on the table, so now both CO2 X and Y are running with beam dumps in place. Tomorrow I'll try and adjust the loops to find a more stable system.
