    Default YO-LS302-3 HALP!!

    SO my friend Gave me a mystery projector its a YO-LS302-3 700 mw not to bad for Chinese laser stuff. My problem is I have never seen galvos like this before and the pots are not marked and this thing needs to be tuned. The only markings are on the show card "pes-control-sd-v1.1.pcb" Google has nothing for me and a search here only turned up one post from a member who has not been active since 2013. Does any one have any information or ideas on how I can figure out which pot is which on the driver board ?

    I would like to avoid ripping out the galvos and replacing them. \

    thank you
