try to use level gauge to check the alignment of the SampleCase. After
longterm oeperation, something may lose its position.

Subject: [AMMRL] SampleCase error during ejecting sample
Dear all,
I would like to ask about our problem with SampleCase (24 positions, installed
2015) on our Bruker Avance III 600MHz (installed 2009) running Topspin 3.6.4
on linux. In the past, we experienced this error occasionally, it was highly
intermittent with long periods of no problems. Today, we have it back.
When ejecting samples (ej or pressing the button), the sample comes out from the
magnet and is catched on the top. Immediately after, the samplecase issues the
error "BSMS Error: SampleTransporter: Carrier on top of magnet bore detected (BST).
Please remove it manually." and all lights turn red. Removing the sample can be
done in several ways, turn off the sample changer, press emergency stop button
twice, or even just reset samplechanger using the BSMS Service Web tool. During
reset, samplecase detects the sample catched on the top of the magnet and safely
delivers it back to the sample changer, no need to touch anything manually, all
is just a single mouse-click on reset in the webtool.
I have not figured out how to prevent this error. All sensors are clean. Po=
wer cycles done. Firmware reloaded. Spinners new and clean. No mechanical o=
bstacles.
I would be grateful for any ideas.
Best wishes,
Zdeněk Tošner
