Overview

CNC motion controller with 4 integrated stepper drives that communicates with a VFD/LCD pendant, and a PC via Ethernet (or maybe also RS-232?). It was used by OEMs to provide controls on their machines. ExtraTech was bought by Multicam, who used their controllers, but supposedly the employees soon dispersed and Multicam doesn't have the ability to support repairing the controls anymore.
