Hello All,

Yes this is a problem with the pattern generator.  I will be also 
checking the LEO deflection section.

More later,

Hi,

Gigi, do your broken patterns look like this? I got this results back in
September when there was a problem with pattern generator. It showed up on
random people and random writing sessions. For at least 2 weeks I suffered
while nobody was having such a problem ( maybe my patterns are more complex
than others) It has not been fixed until james and other users also start
to have same problem. If you also have same broken type patterns I think it
might be again same problem with pattern generator ?!

Scott, also I remember now that I was getting overlapped patterns. It might
be writing on the same spot so that you get one big blob instead of one
(look at broken_pattern_1 in the attachment, overlaped area is overexposed
and in some of them not even possible to resolve the pattern which is
suppose to be 10 by 10 matrix of  dots)

Since last time it showed on random people and on random writing sessions it
is possible that tomorrow some people can say that they have very good
results. I think maybe James can check if pattern generator OK?

HI Hatice,
yes, I found the same. Some patterns broken, some misplaced, and also
stitching error (but I was expecting the stitching since I could not align
properly: the system is too clean, it's hard to burn a spot @ 10 um ap.!).
Sorry I meant to send an email earlier, but I was busy.
In conclusion, I would not attempt any critical work with the system in
this state, and if other people had the same problem I think there's
really something wrong with the system, not with my sample.
James?
