2.2 CB1 Module Installation

The CB1 compute module serves as the brain for your Klipper setup.

1. Align the CB1 module with the dedicated socket on the Manta M4P motherboard. Ensure the pins are correctly oriented.
2. Gently press the CB1 module into the socket until it is securely seated. Avoid excessive force.
3. If a heatsink is provided for the CB1, attach it according to its specific instructions to ensure proper thermal management.

2.4 Connexions de câblage

Connect all necessary components to the Manta M4P motherboard. Always ensure the power supply is disconnected before making any wiring changes.

• Alimentation: Connect your 24V (or appropriate voltage) power supply to the main power input terminals. Observe correct polarity.
• Moteurs pas à pas : Connect each stepper motor to its corresponding driver socket.
• Chauffages: Connect the hotend heater and heated bed to their respective terminals.
• Thermistors/Sensors: Connect thermistors for hotend and heated bed temperature sensing.
• Fins de course : Connect X, Y, and Z axis endstops.
• Ventilateurs: Connect cooling fans for the hotend, part cooling, and board cooling.
• Périphériques : Connect any additional peripherals such as a display, filament sensor, or auto-leveling probe.

Refer to the detailed pinout diagram available on the BIGTREETECH official website or documentation for precise connection points.

2.5 Firmware Flashing (Klipper)

The Manta M4P is designed for Klipper firmware. The general process involves:

1. Prepare the Klipper firmware for the Manta M4P using the Klipper configuration tool.
2. Transfer the compiled firmware file sur une carte SD.
3. Insert the SD card into the Manta M4P's SD card slot.
4. Power on the board. The firmware should flash automatically.
5. Once flashed, remove the SD card.

Detailed instructions for Klipper installation and configuration can be found on the official Klipper documentation website and BIGTREETECH's GitHub repository.

3. Mode d'emploi

3.1 Mise sous tension et démarrage initial

After completing all wiring and firmware flashing, connect the power supply to the Manta M4P. The board should power on, and the CB1 module will boot its operating system.

3.2 Accessing Klipper Interface

Once the CB1 has booted, you can access the Klipper web interface (e.g., Mainsail or Fluidd) via a web browser on a computer connected to the same network. Enter the IP address of your CB1 module to access the interface.

3.3 Basic Printing Operations

From the Klipper web interface, vous pouvez :

• Télécharger le G-code files pour l'impression.
• Start, pause, or cancel print jobs.
• Monitor printer status, temperatures, and progress.
• Control individual printer components (motors, heaters, fans) for testing or calibration.

4. Entretien

4.1 Nettoyage

Periodically inspect the motherboard for dust accumulation. Use compressed air or a soft brush to gently remove dust from the board and heatsinks. Ensure the board is powered off and disconnected from the power supply before cleaning.

4.2 mises à jour du micrologiciel

Regularly check for updates to Klipper firmware and the CB1 operating system. Keeping your software up-to-date ensures access to the latest features, bug fixes, and performance improvements. Follow the official documentation for update procedures.

4.3 Vérifications des composants

Occasionally check all wiring connections to ensure they are secure. Inspect stepper motor drivers and heatsinks for proper seating and thermal contact.

5. Dépannage

5.1 Board Not Powering On

• Verify the power supply is connected correctly and providing the correct voltage.
• Check all power connections for loose wires or incorrect polarity.
• Assurez-vous que l'alimentation est sous tension.

5.2 Stepper Motors Not Moving

• Confirm stepper motor drivers are correctly installed and oriented.
• Check motor wiring for correct pinout and secure connections.
• Verify Klipper configuration for motor definitions and current settings.
• Ensure the motor power (VMOT) is supplied to the board.

5.3 Communication Issues with Klipper

• Ensure the CB1 module is properly seated and powered.
• Check network connectivity between your computer and the CB1 module.
• Verify the Klipper firmware on the Manta M4P is correctly flashed and configured.
• Consult Klipper logs for error messages.
