4. Setup Guide

4.1. Pre-installation Checklist

• Ensure your 3D printer is powered off and disconnected from the mains.
• Gather necessary tools: screwdriver set, wire cutters/strippers, multimeter (optional).
• Familiarize yourself with your 3D printer's existing wiring and mainboard layout.
• Download the latest firmware (Klipper or Marlin) compatible with Manta E3EZ from the official BIGTREETECH GitHub repository.

4.2. Installation Steps

1. Remove Old Mainboard: Carefully disconnect all wires from your existing 3D printer mainboard. Take photos for reference if needed. Unscrew and remove the old mainboard.
2. Install Manta E3EZ: Mount the BIGTREETECH Manta E3EZ board into the designated mainboard slot of your Ender-3 series or Voron printer. Ensure it is securely fastened.
3. Connect CB1 eMMC: Insert the CB1 eMMC core control board into the dedicated BTB socket on the Manta E3EZ board. Ensure proper alignment and firm connection.
4. Wire Components: Reconnect all motor, endstop, heater, thermistor, and fan wires to their corresponding ports on the Manta E3EZ board, referring to the interface diagram (Figure 3.5). Pay close attention to polarity for power connections.
5. Power Supply Connection: Connect the printer's power supply to the Manta E3EZ board. Verify voltage settings if applicable.
6. Initial Power On: Before connecting to a computer, briefly power on the printer to check for any immediate issues (e.g., smoke, unusual smells). If all seems well, power off.
7. Firmware Flashing: Connect the board to your computer via USB. Follow the specific instructions provided by BIGTREETECH for flashing Klipper or Marlin firmware onto the Manta E3EZ board. This typically involves placing a firmware file on an SD card and inserting it into the board, or using a DFU utility.
8. Configuration: Configure the firmware settings (e.g., printer dimensions, motor steps, thermistor types) according to your specific printer model and components.

5. Operating Instructions

5.1. Klipper Firmware Operation

For Klipper users, the CB1 eMMC acts as the host for the Klipper firmware. You will typically interact with Klipper via a web interface (e.g., Mainsail or Fluidd) accessible from your computer or a network device.

• Network Connection: Ensure the CB1 eMMC is connected to your network via Ethernet or Wi-Fi.
• Access Web Interface: Open a web browser and navigate to the IP address of your CB1 eMMC (or the hostname if configured).
• Printer Control: Use the web interface to control printer movements, temperatures, and start/stop prints.
• G-code Upload: Upload G-code files directly to the CB1 eMMC via the web interface for printing.

5.2. Marlin Firmware Operation (if applicable)

If you choose to use Marlin firmware, operation will be similar to other Marlin-based mainboards, typically through an LCD screen or a host software like Pronterface or OctoPrint.

• LCD Control: Navigate menus and control printer functions directly from the connected LCD screen.
• USB Connection: Connect the Manta E3EZ to your computer via USB for direct control and G-code sending using host software.
