I think this is how real galvos work, as they always spring back to the middle. The amount of movement from them is tiny though, it's more like rotational vibrations.wummi said:thanks for the advice, for now i'm powering them at 0.5W max.
the problem is, the arms dont return to zero fast/precise enough. i guess rubberbands just dont cut it
how do real galvos work this?
has someone built somethin like i did here?
im thinking of giving each coil a DC offset, maybe 2V, an modulate from 1V to 3V with 2 being the zero point. anyone think that will work ?!
