Scott,
I did a servo mini-mill conversion prior to converting my large Tree
mill. I set up the mini-mill with 22 inch pound geared servo motors
with encoders on the x,y and Z axis. I used this as a test bed with
JRKerr drivers and Gecko 340's to test concepts before tackling the
big machine.

I have since abandonded this machine. If you have any interest I
would be willing to sell you the motors, mounts, Z leadscrew and
limit switches and mounts (or the whole machine). I also have a set
of JRKerr step direction servo drivers available. I used the Gecko's
on my big mill. The JRKerrs worked but were a bit more comlex than
the Gecko's.

Let me know off list if you are interested and I will post some yahoo
pictures.
