[labnetwork] Mann PG3000 pattern generator question

[Robert Vandusen]

Hi everyone.
I was hoping to find someone who may have experience with the Mann PG1600 or PG3000 pattern generator mask making systems.
In our Microfab we have 2 working David W. Mann pattern generators: a PG1600 and a PG3000.  These units are still working fairly well, but we would like to try adjusting the lens focus
to match up with different size plate holders.
I know according to the manual it is a matter of adjusting the knurled vernier wheel at the top of the lens housing.  I have tried this and there does not seem to be any movement.
I did not want to force in case there is something else that needs to be loosened or lubricated first.
I have tried reaching out to my former contacts from the former Mann company with no luck.


Thanks in advance.
Rob
