Dear Cam,
we are running v1.8 since a couple of weeks and I have to say that this
is the first one which hasn't crashed so far. We had more problems with
v1.6 and v1.7. So it might be an electronics problem on your side. I
also know people still having the same crashing issues with every version.
We had the issue of vibrating stage once during the one year we have the
system, similar to your description. The maximum allowed load for this
stage is quite low (100g?), so I have the suspicion that this vibration
issue could be due to overloading. We also have an older SP2 with Galvo
Stage and this is out of calibration from time to time, probably also
because of overload - this one is an upright stand, so as soon as you
hit the sample with the objective it's for sure more than 100g...
cheers,
Michael
