Ardunio CNC Shield | Arduino Uno CNC Shield

The Arduino CNC Shield is a modularly-designed expansion for the Arduino UNO R3, which expands on the functionality of the UNO board and converts digital signals into computerized numerical control values (or CNC values). These can be utilized for CNC machines to cut, drill, bore or mill materials via accurately controlled Stepper Motors.

What makes the Arduino CNC Shield a great investment, when compared to custom-designed boards, is that they are extremely easy to use, and can simply plug directly onto the top of a standard Arduino UNO board. After this easy installation, makers can utilize freely available GRBL software to create HEX files and upload control specifications directly to the Arduino board. These HEX files, in conjunction with the functionality of the CNC shield, will control the stepper motors with precision allowing makers to create their own drilling, milling and cutting CNC machines at home.

Our Arduino CNC Shield is compatible with all standard Arduino UNO boards and can connect to up to four stepper motors. It provides microstepping selection pins for each of the Motors and is 100% compatible with GRBL software. Additionally, it has Max and Min endstop pins as well as spindle and coolant pins for greater control, while the emergency stop pin helps protect the components and system from excessive damage if faults arise.
