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)
Spindle enable and direction
Coolant enable
Uses removable A4988 compatible stepper drivers. (A4988, DRV8825 and others)
Jumpers to set the Micro-Stepping for the stepper drivers.(Some drivers like the DRV8825 can do up to 1/32 micro-stepping)
Stepper Motors can be connected with 4 pin molex connectors.
Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
Arduino CNC Shield is the PCB you need to control the stepper motors.
This PCB is perfect if you want to assemble your first CNC low cost machine such as a laser cutter, using an Arduino Uno.
It is totally compatible with the popular GRBL firmware.
It supports up to 4 motors with A4988 or DRV8825 drivers.
GRBL (pronounced “gerbil”) is a free open-sourcesoftware that’s used for motion control with Arduino boards that use the ATmega328. This enables us to use an Arduino UNO to operate CNC machines (laser cutters, 3D printers, etc). Basically, we can use GRBL and an Arduino UNO to operate any machine that has 3-axis.
The Arduino CNC Shield basically allows you to easily connect up to 4 stepper motor drivers and motors to your Arduino project while connecting them to very specific pins in the Arduino UNO. The GRBL software, which you have to deploy into your Arduino, knows which pins are used to control each stepper motor, so the Arduino CNC Shield and GRBL work very well together.
