2. Key Features

The Manta M5P+CB1 V2.2 system offers a range of features designed to enhance 3D printer control and performance:

Klipper Optimization: Engineered to run Klipper firmware directly with the CB1 core board, providing advanced control and faster processing. Without the CB1, the Manta M5P can run Marlin firmware.
CB1 Core Board (V2.2): Features a 64-bit ARM Cortex-A53 1.5GHz quad-core processor, 1GB DDR3 RAM, 100M Ethernet, and 100M WiFi. It supports Linux/Debian, offering high speed and stability for various applications.
Integrated Display Interfaces: Includes an onboard HDMI interface for direct connection to BIGTREETECH HDMI5/HDMI7 touchscreens and an SPI interface for compatible SPI touchscreens, enabling intuitive operation.
Extensive Connectivity: Supports plug-and-play USB cameras for monitoring, and features dedicated ports for filament runout sensors, RGB light strips, BLTouch, and ADXL345 accelerometers.
Advanced Driver Support: Integrated SPI and UART modes for TMC drivers (e.g., TMC2209, TMC2208, TMC5160T Pro) with easily configurable jumpers and a DIAG pin.
Enhanced Power Management: Utilizes a TPS5450-5A power chip providing 5A output, matching Raspberry Pi power requirements. High-efficiency MOSFETs reduce heat generation.
CAN Bus Support: Simplifies wiring and improves anti-interference capabilities.
User-Friendly Upgrades: MCU firmware can be upgraded via an SD card or DFU mode using Klipper's make flash command. Features replaceable fuses for easy maintenance.

3. Setup and Installation

3.1 Hardware Installation

Mounting the CB1: Carefully align the BTB headers of the CB1 V2.2 core board with the corresponding headers on the Manta M5P motherboard. Gently press down until the CB1 is securely seated.
Power Connection: Connect a suitable 24V DC power supply to the Manta M5P. Ensure the polarity is correct. The board features a 5A power chip for stable operation.
Stepper Motor Drivers: Install your TMC stepper motor drivers (e.g., TMC2209, TMC2208, TMC5160T Pro) into the designated sockets (M0-M4). Configure the jumpers for SPI or UART mode as required by your drivers and desired functionality. Refer to the driver's specific documentation for jumper settings.
Peripheral Connections:
- Endstops: Connect X, Y, Z endstops to the respective ports. Pay close attention to wiring to avoid misconfiguration.
- Heaters & Thermistors: Connect hotend and heated bed heaters, along with their corresponding thermistors.
- Fans: Connect part cooling and hotend fans to the appropriate fan ports. The Manta M5P has three 2-pin fan ports, selectable for 5V/12V/24V.
- Display: Connect your HDMI5/HDMI7 touchscreen via an HDMI cable or an SPI touchscreen to the SPI interface.
- Sensors: Connect optional sensors such as filament runout detectors, BLTouch, or ADXL345 accelerometers to their dedicated ports.
- USB Camera: Plug in a compatible USB camera for remote monitoring.
- RGB Light Strip: Connect an RGB light strip if desired.
Network Connection: Connect an Ethernet cable for wired network access, or ensure the CB1's WiFi antenna is properly connected for wireless connectivity.

3.2 Software Configuration

For detailed software setup, including Klipper firmware installation and configuration, please refer to the official BIGTREETECH GitHub repository. This resource provides the most up-to-date instructions and configuration files for your specific setup.

Klipper Firmware: Follow the instructions on the BIGTREETECH GitHub for compiling and flashing Klipper firmware to the Manta M5P and configuring the CB1 for Linux operation.
Marlin Firmware: If you choose to run Marlin firmware without the CB1, download the appropriate Marlin firmware for the Manta M5P and configure it according to your printer's specifications.

4. Operating Instructions

Once the hardware is installed and the firmware is configured, you can begin operating your 3D printer with the Manta M5P+CB1 V2.2 system.

Klipper Interface: Access Klipper's web interface (e.g., Mainsail or Fluidd) via your web browser using the IP address of your CB1. From here, you can control your printer, upload G-code, monitor print progress, and adjust settings.
Local Display: If using an HDMI or SPI touchscreen, you can interact directly with the printer's interface for basic controls and monitoring.
Remote Monitoring: Utilize the connected USB camera to remotely monitor your 3D printing projects through the Klipper web interface.

5. Maintenance

Regular maintenance ensures the longevity and reliable operation of your Manta M5P+CB1 V2.2 Core Board.

Firmware Updates: Periodically check the BIGTREETECH GitHub for firmware updates. MCU firmware can be updated via an SD card or by using the DFU mode with Klipper's make flash command. Keeping firmware updated can introduce new features and bug fixes.
Fuse Replacement: The board features replaceable fuses. If a fuse blows, replace it with a fuse of the same rating to prevent damage to the board or connected components.
Cleaning: Keep the board free from dust and debris. Use compressed air or a soft brush to gently clean the components. Ensure the board is powered off and disconnected before cleaning.
Connection Checks: Periodically inspect all cable connections to ensure they are secure and free from damage. Loose connections can lead to intermittent issues.
