CNC shield v3 engraving machine 3D Printer A4988 DRV8825 driver expansion board

The CNC Shield V3.0 is a versatile expansion board that allows you to build various CNC machines, including engraving machines, 3D printers, mini CNCs, and more using your Arduino. Here are its key features and specifications:

  Features:  

• Designed as a shield for Arduino, requiring no external connections or wiring
• 4 slots for plugging in stepper motor drive modules, each capable of driving 1 stepper motor
• Controlling each stepper motor requires only two IO pins on the Arduino
• Compatible with Arduino UNO
• Supports GRBL 0.9 firmware (Open-source firmware that turns G-code commands into stepper signals)
• Supports PWM Spindle and direction pins
• 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)
• Supports Coolant enable
• Supports removable A4988 compatible stepper drivers (A4988, DRV8825, and others) - drivers not included
• Jumpers to set the Micro-Stepping for the stepper drivers (Some drivers like the DRV8825 can do up to 1/32 micro-stepping)
• Compact design
• Stepper Motors can be connected with 4-pin molex connectors or soldered in place
• Runs on 12-36V DC (At the moment, only the DRV8825 drivers can handle up to 36V, so please consider the operation voltage when powering the board)

  Specifications:  

• Length: 68mm
• Width: 52mm
• Height: 18mm
• Weight: 30g

  Package Includes:  

• 1 x CNC Shield V3 expansion board

This shield is ideal for DIY enthusiasts looking to build their own CNC machines or 3D printers, providing a cost-effective and easy-to-use solution for stepper motor control.
