Description

CNC Shield Board:

  • Latest CNC Shield Version 3.0 for Arduino.
  • GRBL 0.9 compatible. (Open source firmware that runs on an UNO for Arduino that turns G-code commands into stepper signals)
  • PWM Spindle and direction pins
  • 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a  full 4th axis with custom firmware using pins D12 and D13)
  • 2 x End stops for each axis (6 in total)
  • Coolant enable
  • Uses removable A4988 or DRV8825 compatible stepper drivers
  • Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to  1/32 micro-stepping )
  • Compact design.
  • Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
  • Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
  • Please note that this is an unassembled kit and Basic soldering skills are needed.

A4988 Stepper Motor Driver:

  • A4988 Stepper Motor Driver Board is a breakout board for Allegro’s A4988 DMOS Micro stepping Driver with Translator and Overcurrent Protection; please read the A4988 datasheet carefully before using this product.
  • Low RDS (On) Output
  • Automatic current decay mode  detection / selection
  • Mix with slow current decay modes
  • Synchronous rectification for low power dissipation
  • Internal UVLO
  • Crossover-current protection
  • 3.3 and 5 V compatible logic supply
  • Thermal shutdown circuitry
  • Ground fault protection
  • Load short-circuit protection
  • Five selectable step modes: full,  1/2, 1/4, 1/8 and 1/16
  • Warning: Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver. (More generally, rewiring anything while it is powered is asking for trouble).
