The controller is not unique to the machine -- it's a Delta Dynapath
10, and I have seen spare parts for it around on the net, but not the
controller boards. There is room in the card cage for two more axes,
wired and ready to go. All that's missing, controller wise, is the board
and the jog switch on the front of the case. The software even seems to
be all in order for more axes.
As for the machine, what's missing there is the servo pack. The servo
pack is something that we can adapt from an existing commercial unit.
Our power downfeed seems to be out, and the only thing we have a manual
for is the control.

Ours uses NMTB #30 tooling. It's a CNC style taper and mounting flange.
Very nice -- beats the pants off of R8. Not too terribly hard to find,
either.
