Is it also worth pointing out that the auto table feed should feed on the ram's return stroke, and go 'Click, click, etc' on the cutting stroke? I've seen them wrongly set…
It's worth checking to see that the ratchet on the table feed doesn't also drag the feed screw backwards, so it oscillates, rather than feeding steadily. IIRC there's no built-in provision for adding some friction to the feedscrew's rotation, to prevent this from happening.
