    Except for those pesky machines that can rotate the head, right? If I rotate my B-Axis the spindle axis is not perpendicular to the X-Y plane, but the Z-Axis still is.

    I'm not familiar with Makino, but I assume there are upper and lower contacts. If it is breaking above the part, I would look at the lower contacts and/or cables. Think of the wire as a fuse that...

    I think that most any machine you run 480V to you can just run an ethernet cable to or fiber to, so no one really does it. I can get behind not wanting to pull another cable in an already installed...
