tuning help please.

[scoot]

hi guys, since i toasted one of my amps i`ve been running my other set of amps and galvos.

i`ve noticed they are not quite as tight as the other set. they are a bit messy on the corners.
i want to have a go at tuning but not untill i know what i`m doing. i had a good look on here but i cant find any info on what to do.

there a 7 pots on my amps:
input scale.
position scale.
input offset.
liearity.
hi freq gain.
low freq gain.
servo gain.

is this standard?
can anybody help me with a procedure?
i think my amps and galvos are the the same ones carmangary sells.
i have taken a couple of photos to show my progress.
also think i may have groundig issues cos when i run live q off a laptop i see quite a lot of noise in the projected image.
thanks.
scoot.

if theses are the the canton scanners you need to put a jummper from w3 to one of the ground screws

from what nancy say this has been fixed on later revs

Those aren't the same ones I sold. Maybe the are the older versions, though. The pots are the standard ones. The LaserFX website has a couple of good documents about tuning.

I tuned mine and I think I did an OK job but I don't like to tell other people how to do it since I may or may not have it quite right. I did it based on the LaserFX documents.
