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.
Power cycles done. Firmware reloaded. Spinners new and clean. No mechanical
obstacles.
I would be grateful for any ideas.
Best wishes,
Zdeněk Tošner
