CNC Controller PoKeys57CNC USB and Ethernet with Mach3 and Mach4 Plugin.

Dump the need for the old school Parallel Port - Connect your CNC to the PC via USB or Ethernet!

PoKeys57CNC is a general purpose motor controller capable of streaming your G-Code from your PC via USB or Ethernet to your CNC machine. The controller supports both Mach3 and Mach4 via Plugins.

The device is able to controlling up to 8 STEP/DIR signal driven motors (stepper motors, servo drives, etc.)

The controller has dedicated, on board, connectors for connection of upto 8 motor drivers, pendants, (HD44780-compatible) LCD module, etc. In addition, 5 analog inputs with 12-bit resolution are available. The device also features four galvanically-isolated open-collector outputs and isolated 0 to 10 V analog output.

A dedicated PoExtBus/PoNET connector can be used to extend the number of digital outputs for additional 80 outputs in the form of either relay outputs or open-collector outputs. It can also be used to connect various additional peripherals e.g. the dust tight CNC keyboard PoKeysKBD48CNC.
