table to work.

I mounted it on the milling table a while ago and started integrating
it on Sunday or thereabouts. Constantly being interrupted by the
family, of course.
For feedback, it has a separate tachometer and a "resolver". This
resolver has six leads, two for rotor excitation and two for stator.

I would use Jon's resolver to encoder converter board:

For some reason, two resolver leads (two from separate stators) were
interconnected. At first I thought that I could reuse that old
arrangement instead of the lead pairs being fully isolated and
differential.
Yesterday I had a revelation and changed my mind. I decided that an
extra week spent on doing things the right way would be time well
spent. I decided to replace the terminal strip on the rotary table
to accommodate completely isolated stators, add a connection for home
switch, etc.
So I ripped everything apart again and will use a 12 lead cable, with
every lead pair shielded individually.
1) 6 wires (3 pairs) for the resolver
2) 2 wires for the tachometer
3) 2 wires for home switch
4) (possibly) 2 wires for limit switch.
As of now, not much has been done after ripping things out, but
perhaps tonight I will get 25% of work done.
