Fanuc 6m help

Hello everyone: My name is Don Blausey and I joined the group
recently.
I have a gorton mill with a fanuc 6m control on it. I have used this
mill for the past few years in my home shop. While using it a few
weeks ago the control died as it has frequently in the past year. I
would like
to save the drives and the motors and install a new control. I know
that
I will have to change the resolver to encoders. I have learned that
from the many web sites I have viewed in the past few weeks. I have
been following this site and am not sure if I am in the right place.
This machine has a 10" x 50" table on it, and most of the post are for
table top machines. I have checked out camsoft and a few others and
not ready to spend that on this machine. Repairs on old boards are not
cheap either. Has any one else done this or have a sugestion on what
to do. Any help greatly appreciated.
