2 – Control Module Design
Connection for offline-controller
An external offline-controller can be connected to the 8-pin tub connector. This makes it possible to operate the CNC
milling/engraving machine connected to the control module independently without an additional PC. In such a case, the
positioning data (g-code) are stored beforehand on a micro-SD card located in the offline-controller.
