Coming with it there is a unexpected 'feature' (according to FEI): The CCD camera is retracted when the emptying buffer tank start to run, but NOT reinserted afterwards. Such behaviour totally defeats any intention of running unsupervised automatic data collection, including FEI's own software. I am wondering if anyone else had similar experience and how to get around of it. Your help is appreciated.
