Arduino CNC Shield

Arduino UNO CNC Shield Stepper Motor Driver Board V3

A4988 DRV8825 DRV8833 CNC 3D Printer Engraving Machines

     You can make cnc and 3d printer applications with this arduino shield board. It can drive four A4988 stepper motors. Thanks to this, 4 stepper motors can be driven with a single Shield.
     The board is compatible with the open source CNC control software Grbl.  Thanks to GRBL's libraries written for Arduino, you can make a motor run by just setting the pin high/low. Thanks to this simple usage, the Arduino processor can drive more than one stepper motor sufficiently and without being overworked. 
     In addition, to run the stepper motors, it can also be controlled with boards external to arduino via the parallel male header sockets. 

     Another good feature of the A4988 Driver CNC Shield Expansion Board for Arduino is that it can clone the movement of one of the other two motors. Since there are many CNC or 3D printer systems with dual motors for a single axis, this feature makes the mainboard quite a good choice for use with these systems.
 
     GRBL is a free, open source, high performance software to control the movements of moving machines and to run on a plain Arduino. The CNC shield works compatible with GRBL.
