myCNC-ET1 Ethernet CNC controller (top view)

 

MyCNC-ET1 «All-in-One» CNC Controller / Motion Controller / Programmable Logic Controller (PLC).

Controller can work as independent unit as well as with Host PC connected through Ethernet/USB/RS485.

myCNC-ET1 Controller board based on 100MHz 32bit ARM Cortex-M3 Processor and Altera FPGA logic.

Controller contains:

  • Motion controller with true multi-axes line, arc, spiral, spline interpolators;
  • Programmamle Logic Conroller;
  • An interpreter for G-codes (the RS-274 machine tool programming language);
