I would like to mention that during the Vacuum startup, after the AUX pump was turned on, Tega and I were walking away while the pressure decreases. While we were, valves opened on their own. Nobody was near the VAC Desktop during this. I asked Koji if this may be an automatic startup, but he said the valves shouldn't open unless they are explicitely told to do so. Has anyone encountered this before?

We followed the instructions here. There were no major issues, apart from the fb1 ntp server sync taking long time after rebooting once.
We noticed that ETMY had to much RMS motion when the OpLevs were off. We played with it a bit and noticed two things: Cheby4 filter was on for SUS_POS and the limiter on ULCOIL was on at 0 limit. We turned both off.
We did some damping test and observed that the PIT and YAW motion were overdamped. We tune the gain of the filters in the following way:
These action seem to make things better.
