Hi Jay,
Did you swab the bore with Kim wipes taped on the end of a wood dowel and
doused with iPrOH? Did you clean your spinners? Other than running a lineshape
analysis, do you really need to spin at 20 Hz for liquids? I don't.

I need some ideas and this group has always been the best place to look.
We have an Bruker Advance 600 that stopped spinning solution samples. It was
spinning at 20 Hz and then lower like 10 Hz and now it is not spinning at all.
I think that it went from 20 Hz to 0 Hz in a few days. The pressure to the
console is fine. I assume that something was dirty or that there was a blockage,
so I took the shim stack, probe, and shims out and tried to clean them. When I
had it apart I did not notice anything unusual. I put everything back together
and it still would not spin. I also noticed that on the BSMSdisp it indicated
that the sample was missing, even though the sample was in the magnet.
We also have a decommissioned Advance 400. So, I tried swapping PNK pneumatics
controller boards between the 400 (ECL 00) and 600 (ECL 01), but that did not help.
I also ran the diagnostics on the BSMS unit using “topspin -e bsms” and
all of the boards passed.
I would appreciate any ideas or insights.
Jay
