CNC Controller MACH3 USB 4 Axis

The 4 Axis USB MACH3 Controller Board is a high-performance CNC breakout board designed for MACH3 software. It supports up to 4-axis linkage, making it suitable for driving stepper or servo motors in CNC routers, engraving machines, and milling systems. With a maximum step-pulse frequency of 100KHz, it ensures smooth, precise motion control.

This controller offers multiple input/output options including emergency stop, probe tool support, limit switch connections, and relay outputs for spindle and auxiliary devices. It features a 0–10V analog output for spindle speed control and requires an external 24V DC power supply for stable operation.
