[3view] Motor problems on 3ViewXP2 stage

we are not working with tiling that much, it is rather imaging of several
2-4 rois from time to time.
But still as I recall now we had several occasions when the stage has lost
The symptoms are similar to yours the stage has been moved somewhere far-far
away and the run was terminated.
Because of some factors I was assuming that it was a software problem. Our
system software has been updated at some moment and we did not have this
problem since then. But we did not have that many runs either.
I think it is quite nasty behavior but unfortunately it is rather hard to
fix this bug since it happens quite rare :(

Subject: [3view] Motor problems on 3ViewXP2 stage
We have a 3View XP2 and we often use it for montaging in order to acquire
large fields of view. This involves moving the stage as many times as there
are tiles in the image between cuts.
For several months now, we have been having recurrent problems with that:
- after a number of cuts, the stage suddenly goes to a wrong and completely
different position during the tiling (i.e. between 2 tiles of a section).
Both the position and stage X,Y values are wrong as though the software was
giving bad instructions to the stage.
- or the process just stops and says it can't move the the next tile
(despite it did on the cuts before).
- and the motors are sometimes making loud mechanical noises. But this is
not directly related to the failures above (i.e. not necessarily at the same
The 2 motors were replaced in july by Gatan. In the very beginning it didn't
help. After some software tweaking from Gatan it worked for some time, but
now the problems are back again :(
1 - Anyone also using 3View montaging on a routine basis ?
2 - Anyone also having issues with stage movements on a 3View ?
I'm curious ...
