5. Guia de configuració

Follow these steps to correctly set up your GRBL controller board for operation.

5.1. Connexió a la font d'alimentació

Connect a DC12-48V power supply to the designated input terminals on the board. Ensure the polarity is correct to prevent damage to the board.

5.2. Stepper Motor Connection

Connect your X, Y1, Y2, and Z axis stepper motors to their respective ports. For dual Y-axis operation, ensure both Y1 and Y2 motors are connected and configured correctly for synchronous movement. Refer to your motor's wiring diagram for proper connection.

5.3. Spindle Connection

If using a spindle, connect its power (0-48V) and control (0-500W) wires to the spindle terminals. Consult your spindle's manual for specific wiring instructions.

5.4. Connexió USB

Connect the controller board to your computer using the provided USB data cable. This connection is used for initial setup, firmware flashing, and real-time control via GRBL-compatible software.

5.5. Offline Controller (Optional)

If you are using an optional offline controller, connect it to the dedicated 'Offline controller' port. This allows for independent operation without a computer connection.

6. Instruccions de funcionament

Once the board is set up, follow these instructions to operate your CNC machine.

6.1. Compatibilitat del programari

The board is compatible with various GRBL firmware-supporting software, such as Grblcontrol (Candle). Install your preferred software on your computer and ensure it can communicate with the controller board via the USB connection.

6.2. Configuració Inicial

After connecting, open your GRBL control software. Establish communication with the board. You may need to configure GRBL settings (e.g., steps per mm, maximum feed rates, acceleration) according to your machine's mechanical specifications. Consult your machine's documentation for recommended GRBL settings.

6.3. Running G-Code

Carrega el teu codi G file into the software. Ensure your workpiece is properly secured on the machine bed and the tool is correctly installed and zeroed. Initiate the carving or cutting process from the software interface.

6.4. Offline Control

If an offline controller is connected, you can load G-code files directly onto it (if supported by the offline module) and operate the machine without a continuous computer connection. Refer to the offline controller's manual for specific operation details.
