I am aware of that, and that's why i see the use of a foot as disadvantage.
Keeping all the other things "like the conventional drill press" would
allow quick and easy coarse adjustment of the PCB, to find the holes etc.

By the way, does anyone of you use Toner Transfer and a CNC drill?
I fear the distortions might make cnc drilling difficult?
