3D Printer Kit with CNC Shield and 4 DRV8825 Drivers

Product Details:

CNC Shield Board Specifications:

• Version: 3.0
• Color: Red
• Size (LWH): 68 x 53 x 18 mm
• Voltage: DC 12~36V

Key Features:

1. The CNC Shield Board leverages the convenience of removable A4988 or DRV8825 compatible stepper drivers.
2. This versatile extension board is suitable for a variety of applications, including carving machines and 3D printer driver expansion boards.
3. It is GRBL 0.8 compatible, an open-source firmware that runs on an UNO, converting G-code instructions into stepper signals.
4. This board carries PWM Spindle and direction pins, providing 4-Axis support (X, Y, Z, A- can replicate X, Y, Z or establish a full 4th axis with custom firmware using pins D12 and D13).
5. The compact design allows stepper motors to connect via 4-pin Molex connectors or be soldered directly onto the board.
6. Note: This is an unassembled kit, requiring basic soldering skills for setup.

DRV8825 Stepper Motor Driver Specifications:

• The module’s interface pinout harmonizes with the A4988 stepper motor drive carrier, enabling it as a superior performance replacement in several applications.
• DRV8825 incorporates adjustable current limit, overcurrent, and overtemperature protection along with six micro resolution options (down to 1/32-step).
• Operating at 8.2 – 45V, it can provide up to about 1.5 per phase without a heat sink or forced air flow (up to 2.2 per volume with sufficient additional cooling).

Key Features:

1. The simple step and direction control interface can connect directly to 3.3V and 5V systems.
2. Supports thermal shutdown for over-temperature, over-current shutdown, and under-voltage lockout.
3. Features short-to-ground and shorted-load protection.
4. Offers six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.
5. The device uses a 4-layer, 2 oz copper PCB for improved heat dissipation.
6. Adjustable current control allows you to set the maximum current output with a potentiometer, enabling higher voltage usage for increased step rates.
7. Avails intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay).
8. 45V maximum supply voltage.
9. Features a built-in regulator which needs an external logic voltage supply.
