MyCNC-ET2-STEP «All-in-One» CNC Controller / Motion Controller /
Programmable Logic Controller (PLC) / 3 channel stepper motor driver.

myCNC-ET2-STEP 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, (NURBS
interpolator in developing);
Programmable Logic Conroller (8 inputs, 6 relay outputs, 3 Power PWM outputs);
3 channel stepper motor driver (bipolar driver,48V, 4Amps, suits for 4-,6-
and 8-wired stepper motors)
An interpreter for G-codes (the RS-274 machine tool programming language);
Hardware layer for User interface (9-key membrane keyboard)

myCNC-ET2-STEP technical parameters.

Usually ET2 CNC controller works with myCNC control software.

The last firmware version for myCNC-ET2-STEP controller support stan alone mode. In this mode motion program can be uploaded into the controller board flash memoty. Then controller runs the program without PC Host. Howewer host PC computer may connect to the controller board via Ethernet interface for real-time to diagnose or watch for running process.

Typical application for myCNC-ET2 controller is entry-level cheap 2D/3D CNC machines with stepper motprs up to 4Amps
