I understand that if you are using a +/-10V with encoder feedback directly back
into LinuxCNC that this concept would not work for you. But since you say you
need LinuxCNC can you tell us what you do have?
How is your LinuxCNC connected to your milling machine lead (ball?) screws and
spindle motor?
