CNC Shield V3.0

Definition of CNC Shield V3.0

The CNC Shield V3.0 is a modular board designed for controlling CNC machines. It is an open-source hardware project designed for use with the Arduino platform. The board is compatible with a wide range of stepper motor drivers, including the popular A4988 and DRV8825.

The CNC Shield V3.0 provides a convenient way to connect stepper motors, limit switches, spindle control, and other peripherals to the Arduino board. It also features an onboard micro-SD card reader for storing CNC files, as well as a dedicated pin for connecting an external power supply.

The CNC Shield V3.0 is often used in combination with GRBL, an open-source firmware for controlling CNC machines. With the CNC Shield V3.0 and GRBL, users can create a fully functional CNC machine that can be controlled using G-code commands.

CNC Shield V3.0 pins

The CNC Shield V3.0 has several pins that are used for connecting various components to the board. Here is a brief overview of the pins:

1. Stepper Motor Drivers – There are four sockets for plugging in stepper motor drivers. Each driver has a set of pins for connecting to the motor and power supply.
2. Spindle Control – This pin is used to control the spindle motor on the CNC machine. It is typically connected to a relay module, which in turn controls the spindle motor.
3. Endstop Switches – The CNC Shield V3.0 has three pins for connecting limit switches. These switches are used to detect the limits of the CNC machine’s movement in each axis.
4. Power Supply – There is a dedicated pin for connecting an external power supply to power the stepper motors and other components on the board.
5. Servo Control – This pin is used to control a servo motor, which can be used for a variety of purposes such as tool changing or automatic door opening.
6. Micro-SD Card – The CNC Shield V3.0 features an onboard micro-SD card reader, which can be used to store G-code files.
7. Stepper Motor Outputs – These pins are used to connect the stepper motors to the CNC Shield V3.0. The pins are labeled X, Y, Z, and A, corresponding to the different axes of movement.
8. Coolant Control – This pin is used to control a coolant system, such as a pump or misting system.
9. Spindle PWM – This pin is used to control the speed of the spindle motor using pulse-width modulation (PWM).
