Pete, this mill should be easy to convert, it is very straightforward
in operation. Not sure how easy it would be to mount an encoder on the
spindle, mechanically, this may be an issue.

Yep, no easy place for an encoder, but given the large size it would
seem there should be room to sneak something in. I loaded up LinuxCNC
last night and was surprised at the continued lack of UI refinement, I
would have thought in the last half dozen years it would have improved.
I've got some run caps on order to build up a 14HP RPC with a motor I
have on hand, I may see what I can powerup for testing with the 3HP RPC
I use on my lathe this weekend.

You can run your mill from the small RPC you have, if you have good
voltage balance, just do not load the spindle.

Actually, it should be able to do modest cuts as well, the only 3ph
things in the machine are the spindle VFD and the coolant pump, the
drives and controls are all single phase.

But do all drives run from L1-L2?
