Ethernet CNC controller myCNC-ET5


 Ethernet CNC controller myCNC-ET5


MyCNC-ET5 «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/RS485.


myCNC-ET5 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;
