The C hole looks to be about 2mm high relative to a laser level placed at beamline height (photos to come). The foil platform looks to be pretty level (ie. not bowed) so we wonder if the hole was drilled in the wrong position. Joe has spare (identical) holey carbon foils and will check when he gets a moment.
Bottom line is that the cross hairs on the BeO are likely a better indicator of the true beam axis position.
