MACH3 5-Axis Engraving Machine Interface Board Cnc Interface Board with Optical Coupling Isolated Usb Power Supply

Product Features: Capable of simultaneously connecting up to 5 stepper motor driver boards to control the operation of 5 stepper motors. Features a standard parallel port interface and supports Mach3 software. Includes four input interfaces, allowing for connections to limit switches, emergency stop switches, reset buttons, tool-setting probes, and similar devices Incorporates relay control functionality, enabling the user to control the on/off status (rotation) of the engraving machine's spindle motor Power supply options: Can be powered via a 5V USB port or a dedicated 5V external power supply (Note: Only one of these power sources may be selected at a time; they cannot be used simultaneously.) The external input power terminal located on the left side should only be connected when external input signals are required to be active This interface board features signal amplification for the parallel port outputs, allowing a single channel to drive two separate motor drivers. This provides a convenient solution for users building engraving machines or other automated systems that require dual X, dual Y, or dual Z axes Utilizes pluggable terminal blocks for wiring, offering enhanced convenience and ease of use Color: Green Material: Electronic Component Package Contents: 1*5 axis engraving machine interface board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
