Hi,
i am new to galvo drivers and i hope someone can help me.
i have 2x g120 and amp3 (galvo amp from lobo) .i want to know where the "AGC" connectionis fore. is there aneyone who knows where its fore and what it's value should be???

AGC = automatic gain control.

But I don't know what it is used for on a GS120 amp. Perhaps a drive voltage for the oscillator of the position sensor?
