  • This shield is designed to allow you to control a CNC router or milling machine from an Arduino board. It contains 4 driver sockets which allows compatible A4988 driver modules to be inserted providing the ability to drive 3 stepper motor axis (XY& Z) plus an optional 4th auxiliary motor. Additional connectors provide easy connection of end stop sensors and control buttons. 

    CNC Shield Board Features:

    • GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals).
    • 4-Axis support (XYZA-Can duplicate XYZ or do a full 4th axis with custom firmware using pins D12 and D13).
    • Open source firmware that runs on an UNO for Arduino that turns G-code commands into stepper signals
    • Jumpers to set the Micro-Stepping for the stepper drivers. 
    • Endstop connections.
    • 12-36V input current.
    • X, Y, Z axis and extruder stepper motor control. 

    A4988 Stepper Motor Driver Features: 

    • Automatic current decay mode detection / selection. 
    • Internal UVLO. 
    • Mixed with slow current decay modes. 
    • Synchronous rectification for low power dissipation. 
    • Crossover-current protection. 
    • Thermal shutdown circuitry. 
    • 3.3 and 5 V compatible logic supply. 
    • Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step.
    • Output drive capacity of up to 35 V and ± 1.2 A
    • Thermal shutdown circuitry. 
    • Ground Fault Circuit. 
    • Load short-circuit protection. 
    • Adjustable current control lets you set the maximum current output with a potentiometer.
