Description

The CNC Shield V3.0 is a high-performance control board designed to drive stepper motors in CNC machines, 3D printers, and various automation applications. The shield supports up to four stepper motor driver modules (such as A4988 or DRV8825), providing reliable and precise motor control when suitable drivers are installed.
It is fully compatible with Arduino boards, allowing easy integration into CNC and motion-control projects.

Features

Stepper Driver Support

Supports up to four stepper motor driver modules (A4988, DRV8825, or compatible Pololu-style drivers).
Driver modules are not included and must be installed separately.
Capable of driving stepper motors with high precision depending on the selected driver.

Microstepping Capability

Supports microstepping (up to 1/16 microsteps with A4988, higher with compatible drivers), enabling smooth and accurate motion with reduced vibration and noise.

Adjustable Current Control

Current limiting is adjustable on each installed driver module, allowing fine tuning of motor performance and protection against overheating.

Heat Sink Compatibility

Designed to support the use of heat sinks on driver modules for improved heat dissipation and stable operation (heat sinks not included).

Arduino Compatibility

Compatible with Arduino Uno and other Arduino boards with the same pin layout.
Plug-and-play shield design for easy installation.

User-Friendly Connections

Clearly labeled connectors for:
- Stepper motors
- Limit (endstop) switches
- Spindle enable and direction
- Coolant control

Onboard Power Stabilization

Includes onboard capacitors to stabilize the motor power supply and reduce electrical noise.

GRBL Firmware Support

Fully compatible with GRBL firmware, enabling control through standard CNC software and G-code senders.

Compact and Durable Design

Compact form factor suitable for most CNC enclosures.
Built with durable materials for reliable long-term operation.

Protection Features

Designed to help protect the shield and connected components when used with properly configured drivers and power supplies.
