I remembered the instructions from the build manual on Pausing prints (on this page http://wiki.e3d-online.com/wiki/Your_First_Print ) They're not entirely clear because the photo shows the menu set to "stop print" which I'd already determined was definitely a "stop" with no chance of "resume". Just now something weird was happening with the infill (is it the case that a small part with high percentage infill can get messy, with a build up of plastic even with a well adjusted Z? Could it be that putting the printer on polystyrene is not a good idea when there are lots of zippy movements because it seems to rock a little?). Decided now was time to tryout "Pause". Noticed that, unlike in the build manual, after a "Pause" there's no chance of pushing the printhead out the way. So used the steppers and moved it aside to study the print. When satisfied, decided to "resume" (after removing a lump of plastic) and, as the manual says, hit "auto home". Since it was a small part, and given the position of the printhead, this was possible. But then when I selected "resume" - in blind faith - the printhead went directly for the part with predicable consequences. Too bad the kill switch is not yet installed. Note to self: supergluing the IR sensor is not really enough... Print one when you've got the XT spool in. Anyone else try the "Pause" feature?
