EC300 Ethernet CNC Controller for Mach3 – 3 to 6 Axes

The EC300 is a modern Ethernet CNC controller, compatible with Mach3 software, designed for controlling CNC machines with stepper or servo motors. The controller supports 3 to 6 axes (X, Y, Z, A, B, C) and is an ideal solution for both building new CNC systems and upgrading existing machines.

Unlike older LPT (parallel) ports, the EC300 uses an Ethernet connection, ensuring more stable communication, higher speed, and compatibility with all modern computers. The controller offers a high control frequency – up to 300 kHz per axis, guaranteeing smooth and precise movements even at high speeds.

The device features opto-isolated inputs and outputs, an analog 0–10 V output for spindle control, relays for additional functions, and the ability to connect an MPG handwheel for precise manual control.

The EC300 is suitable for CNC routers, milling machines, engraving machines, plasma systems, woodworking, and metalworking applications.
