Al, that's pricey, hard to find wire alright! I found it priced near $1000 for a 500' roll. I think I will go with a local supplier who has the same spec'd wire. I only need to run 15' for my Z axis, so I don't think I need to go overboard. I will be separating my power and signal cables, switching to differential encoders and going with STP wire on all axes, so the combination should be pretty bulletproof. Any benefit the Belden wire might give me will be negated by having my encoder mounted directly to my servo.
