CNC Controller from SZGH for 3-Axis Mills

I have two new/uninstalled CNC controller I bought to use in my machine shop to retrofit old CNC knee mills. I had already retrofitted to other CNC knee mills successfully but I kept losing servo motors NOT due to the CNC. The mills were just too old. I have those controllers listed separately. THESE CONTROLLERS ARE NOT FOR FIRST-TIME INSTALLERS!!!! ALSO: THE CONTROLLERS ARE OPEN-LOOP CONTROL. THE ENCODER FEADBACK MERELY ALERTS YOU TO AN AXIS MOVEMENT FAULT. You can download the manuals from the SZGH website. All cable you will need are included and professionally labeled. The picture showing the controllers as installed in an enclosure is just for reference.
