Allowing fast drag-and-drop bidirectional file transfers between any CNC and PCs on network, LANCNC controller uses standard PC software. It stores programs at CNC via 2 GB SD card, so programs can be accessed without using network resources. In case of network outage, file transfer and DNC are unaffected. LCD display with keypad module mounted on CNC pendant handles file selection/transfer. With optional wireless router, LANCNC can operate as wireless server.
