Four-Axis Mach3 USB CNC Controller Board

Connect a compatible Mach3 CNC computer to external motor drives with a four-axis USB motion-controller interface.

✅ Coordinate up to four drive channels - Four-axis support provides control signals for compatible stepper or servo drives.

✅ Bring machine inputs into the control - Probe and limit-input connections let the configured software receive supported machine events.

✅ Set a compatible spindle command - A 0-10 V output offers a speed-reference signal for a matching spindle controller.

✅ Move the computer link to USB - The USB interface provides the communication path for the supported Mach3 arrangement.

Build the controller into the machine system

A motion interface sits between CNC software and the machine's drives. This board provides the signal connections, while separate drive electronics and the machine's mechanical system do the powered movement.

Confirm the exact Mach3 driver/software support before wiring. External 24 V DC is required for the described isolated interface arrangement, and emergency stopping must be designed as part of the machine rather than relying only on a software input.
