Uno CNC Shield Arduino Project Kit 

Build a CNC Router or Milling Machine

This Arduino Uno based kit allows you to build a CNC Router or a CNC Milling Machine. 

CNC Shield Board:

• Latest Arduino CNC Shield Version 3.0
• GRBL 0.8 compatible. (Open source firmware that runs on  an Arduino UNO 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)
• Coolant enable 
• Uses removable A4988 or DRV8825 compatible stepper  drivers
• 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

Arduino UNO R3 Board:

• MCU: ATmega328

• USB interface: ATmega16U2

• Operating voltage: 5V

• Digital I/O pins: 14 (including 6  with PWM capability)

• Analog input pins: 6

• I-I/O pin output current: 40mA max

• 3.3V output current: 150mA max

• Flash memory: 32 kB (0.5kB used by  bootloader - included)

• Static RAM (SRAM): 2 kB

• EEPROM: 1 kB

• Clock speed: 16MHz

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
