Don't think I've ever seen manual enable / disable switches for each Axis - I'm not sure there would be a big use case, unless you wanted to manually position an axis for some reason without using Jog and with no care to machine home or soft limits.

What is commonly done is to wire the enable line up to the controller, so that it can enable the drive when sending it movement commands. I use this as part of my fault system - if one of the drivers or the Spindle has an error, the drives remain powered but are stopped in their tracks and disabled through the enable line. Is that what you're after?
