Hello 7mag,
Sadly the vertical down feed is not terribly good on mini mills, it has a rack and pinion feed and there is slop or play in both directions. This can be lessened by putting shims under the rack which does help to remove some of the play. None of these small mills like plunge milling, they're not really built for such work and tend to vibrate in a frightening manner, and in doing so break your tools, that's expensive. If you have to plunge down with an end cutting mill, pre drill a hole a few thousandth of an inch small in dia., and then plunge down with the end mill. It's awkward but on all machines if any size there are snags or faults that you have to overcome. That's life, sorry.
