Haven't even connected a single wire to the G340's I took delivery of
very recently :-( There should have been a notice up to let buyers

The presence of dither means that the servo is always seeking
the "correct" position means that servo is always overcorrecting,
then undercorrecting. Re: the old servo vs stepper "controversy".
