  • Had a failure with the BCU2K that was causing the loop to go not live.
  • Resetting the BCU2K was the fix.
  • This happened on an attempted offset

  • Took a while to correctly diagnose. Jenny helped. We don't see this on LUCI, that I'm aware of.

  • They wanted fewer modes, we're going to go to bin2, but that should do it.
  • Bin2 1207 Hz
  • Camera lens is at a limit, but I think that we can still go.
  • Nope, switching back to the previous configuration.
