LW50K scanner tuning guide needed (need to know what each potmeter does.

Hey guys,

I have an RGB laser projector here, works great.
However there is something wrong with its scanning size.
It does the full width in the X axis but barely 1/4th in the y axis.

Is it possible for scanner drivers to lost their tune for any reason?
Are there other things I should diagnose to find the source of the problem?

Does someone have a the documentation for the LW50k galvos? (the documentation is removed from the laserworld site)

I Hope this will help you
