I recently came into possession of a Messer CNC Plasma table . The machine itself needs some work, but the electrical side of it is definitely non-functional and I believe will need to be replaced. I've retrofit a few milling machines in the past 3 years with Centroid controllers, which some decent results and plan to do the same here now that Centroid has released their own THC.

In the past I used closed-loop, 11.5N-m, steppers motors to drive the mills I've worked on, those motor leads were only 4ft long at a maximum. This Plasma CNC machine has a bed size of 10' x 6' and the whole machine is 17' in length and 9' wide. After measuring some of the existing wire lengths to the Z-axis (to the existing servo motors) they are almost 30 feet in length.

Here's the question; Will a 60V, 11.5 N-m, Stepper motor with encoder feed back function properly on a 30 foot (9 meter) wire lead? If not, what type of drive system would be better suited to it?

Thanks,
