The table is 48.5" x 48.5". If you could get large sheets of PC board then it would be easy to do multiple boards in one shot.
Right now the surface of the table is a grating, as it is was orignially just for plasma cutting.

It would be simple to put a 1/2-3/4" piece of MDF on top with fixturing pins.
For now Paul can make the beta units with his mill, but when we move beyond the beta stage this is the way to go. You could do a thousand boards a day with this machine.
Also, this machine could be used to machine the end plates for the enclosures, as was resently mentioned. The Zilla controllers have a metal enclosure and plastic end caps for the busbar and interface connections to poke through.
I'm going to start looking for a lower speed drill type tool to attach to the tool holder.
