    Default Pro20 Scanner Calibration

    Hi,

    Does anyone happen to know which pots are the servo gain, the low frequency damping, and the high frequency damping on this set of Pro20 galvos? (attached see picture). All the other galvos I've seen have the pots labeled on the circuit board. I would like to follow Adam's tunning writeup (https://photonlexicon.com/forums/showthread.php/3707-How-to-tune-your-scanners) but I'm afraid of touching the wrong pots since they are not labeled.

    Hi There!

    I have a set of these. Here is a link to the PDF documentation: http://www.lasershowparts.com/files/.../SCANLSP20.pdf

    It's hard to read the actual labels on the pots in the picture in the PDF however the order in the potentiometer description should be the order in the picture (top to bottom).

    I relabeled it and made it a PNG file:
