4. Setup Guide

Follow these steps to set up your Yoidesu 2 Axis GRBL Control Board:

1. Identify Components: Familiarize yourself with the various ports and components on the control board. Refer to Image 4.1 for a detailed layout.
2. Connect Power: Connect a DC 12V-5A power supply to the 'Power Source 0-12V' input port on the board.
3. Connect Motors: Connect your X-axis and Y-axis stepper motors to the corresponding 'X Axes', 'Y1 Axes', and 'Y2 Axes' ports. Ensure the motor line sequence (1A, 1B, 2A, 2B) is correctly followed as indicated in Image 4.2.
4. Connect Limit Switches (Optional): If using limit switches, connect them to the 'Limit 5V/GND/S' ports for X and Y axes.
5. Connect Laser/Spindle (Optional): For laser engraving or spindle control, connect to the 'Beam PWM/GND/12V' port.
6. Connect to Computer: Use the provided Type-C USB cable to connect the control board to your computer. The board features auto USB recognition, which will automatically disable offline interfaces upon connection to prevent data interference.

5. Operating Instructions

Once the control board is set up and connected to your computer, you can begin operating your CNC machine:

1. Software Installation: Install the appropriate software on your computer. For Windows users, LaserGRBL is recommended. For Windows, Linux, or OS X users, LaserWeb is also supported.
2. Load G-Code: Open your chosen software and load the G-code file for your desired engraving or milling project.
3. Initiate Operation: Follow the software's instructions to start the engraving or milling process. The 32-bit MCU ensures faster work speeds of up to 40,000 mm/min.
4. Offline Engraving: The board supports offline engraving. When the USB cable is connected to a computer, the offline interface is automatically disabled to prevent data interference. This ensures a smooth transition between online and offline modes.

6. Maintenance

Proper maintenance will extend the lifespan and ensure optimal performance of your control board:

• Keep Clean: Regularly clean the board with a soft, dry brush or compressed air to remove dust and debris. Ensure no conductive materials accumulate on the board.
• Avoid Moisture: Keep the control board in a dry environment. Moisture can cause short circuits and damage components.
• Handle with Care: Avoid dropping or subjecting the board to physical shocks, which can damage internal components or solder joints.
• Power Off Before Disconnecting: Always power off the control board and connected devices before disconnecting any cables or making changes to the wiring.

7. Troubleshooting

If you encounter issues with your Yoidesu 2 Axis GRBL Control Board, refer to the following common problems and solutions:

• Board Not Powering On:
  • Ensure the 12V-5A power supply is correctly connected and functioning.
  • Check the power cable for any damage.
• Computer Not Recognizing Board:
  • Verify the Type-C USB cable is securely connected to both the board and the computer.
  • Try a different USB port on your computer.
  • Ensure necessary drivers are installed (often automatically with GRBL software).
• Motors Not Moving or Moving Incorrectly:
  • Check motor wiring connections for correct sequence (1A, 1B, 2A, 2B).
  • Confirm that the power supply is adequate for both the board and the motors.
  • Verify G-code commands are correct and software settings match your machine configuration.
• Offline Interface Interference:
  • This board features automatic shielding. Ensure only one interface (USB or offline controller) is actively connected for data transmission at a time.
