CNC Shield Board for A4988 Stepper Motor Driver For Arduino V3 Engraver 3D Printer

This is the Arduino CNC Shield V3. This expansion board has a driver expansion board that can be used for engraving machines, 3D printers, and Arduino UNO. It has a total of four slots, can drive four Nema17 stepper motors.

CNC Shield Specifications:

• Compatible with: Arduino Uno
• Input voltage: 12-36V
• Max number of stepper motors channels: 4
• GRBL compatible: Yes
• Hardware version: 3.0

CNC Shield Features:

• GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals
• 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, Coolant enable and direction
• 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 )
• Compact design
• Stepper Motors can be connected with 4 pin molex connectors.
• 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.)

Warning: Connecting or disconnecting stepping motor while driver is powered on might damage driver.
