Hey Jim, this has popped up and Mike Grove of Brukertold me to:" go to
/conf/instr/probeheads and find the .bb file for the probe installed. Open
the text file and find the $atmaposset line for the nucleus and lock solvent
(mine was solvent specific failure) after the solvent name there are a bunch
of commas and numbers etc. that are the Starting Positions for the tuning
motors. Easiest fix is probably just replace numbers in DMSO line (my solvent
was DMSO for the ATMA error) with the ones in the Acetone line and save the
file. Then try the ATMA with DMSO. Correcting motor positions should do
the trick."
The lines I used look like this:
DMSO -001,+000.0235, +00.0024 + 008#
Acetone -001, +000.0021, +00.0026 +008#
so I changed that +000.0235 number for DMSO to be +000.0021 and it did indeed
do the trick! That was in 10/18/24, later in 4/11/25 it happened again this
time for CDCl3. My notes don't say what solvent I compared to but it was a
number 000.0235 changed to 000.024 but also needed a Topspin restart to
take effect.

HI Jim
have you tried unplugging and replugging the PICS cable?

i all, I'm getting this message, which I think means that the tuning rods
are pinned. I can tune fine on 13C.

This is on a Bruker 600 Avance Probe TXI 600S3 H-C/N-D-05 Z
I know that a user was trying to tune the 1H channel to 19F, which I don't
think this probe will do.
Any comments would be welcome!
Thanks
Jim
