 +==== Day 2026-03-01 (rahix) ====
 +Tried connecting ''FRONT'', ''BACK1'', and ''BACK2'' all together using pneumatic T-couplers.  It doesn't work, the weight of the column is too much off the side, meaning one bellow stays in contact with the bottom while the diagonally opposite one is at the top limit.
 +
 +Reverted back to the previous state with three separate valves.
 +==== Day 2026-02-14 (rahix) ====
 +Fixed the very leaky tire valves of the isolation system. We now have proper pneumatic isolation valves on all three tubes instead.  They are labelled now:

 +The back bellows are labelled ''BACK1'' and ''BACK2'' for clarity:

 +Updated the instructions here: [[equipment:zeiss-dsm-962#setting_up_the_vibration_isolation]]
 +==== Day 2026-01-24 (q3k, rahix, rob, hugo) ====
 +
 +Taught a few more members how to use the DSM.  Started taking notes on the important facts and pictures of the relevant controls so we can create a wiki page with all the info.
 +
 +Noticed that the tire valves for the vibration isolation are now all leaky so it's no longer possible to get the bellows pumped up enough.  Ordered some more ball valves to mitigate it.  But maybe a better solution is more urgent than we hoped...
