- Download and install BLTouch firmware
- Flash firmware via USB
- Configure motherboard settings
3.1. Installing BLTouch Enabled Firmware
Begin by downloading the BLTouch-enabled firmware from Creality’s official website or trusted sources. Extract the firmware files to your computer. Install Arduino IDE and configure it for your Ender 3’s motherboard. Connect the printer to your PC via USB and select the correct COM port. Upload the firmware by clicking “Upload” in Arduino IDE. Ensure the BLTouch sensor is properly connected before flashing to avoid compatibility issues. Follow on-screen instructions to complete the installation successfully.
3.2. Configuring the Motherboard Settings
After installing the firmware, access the motherboard settings via the LCD screen or USB connection. Navigate to the control menu and ensure the BLTouch sensor is recognized. Set the correct input voltage (230V or 115V) to match your region. Enable BLTouch auto bed leveling in the settings. Save the configuration to ensure proper functionality. Verify the motherboard version (e.g., V4.2.7) for compatibility and adjust settings as needed to optimize performance and safety.
Bed Leveling and Calibration
Bed leveling ensures proper print adhesion. Use manual adjustment for basic setup or BLTouch for auto leveling. Tighten screws evenly for a precise calibration, ensuring a perfect first layer every time.
4.1. Manual Bed Leveling Process
Start by preheating the bed to 60°C. Place a sheet of paper on the bed and adjust each corner screw until the paper moves with slight resistance. Tighten each screw in a diagonal pattern to ensure even leveling. Use test prints to fine-tune the bed, ensuring proper adhesion and preventing warping. Repeat as needed for optimal calibration.
4.2. Using BLTouch for Auto Bed Leveling
Install BLTouch-enabled firmware and remove the C7 capacitor for V3.0 models. Mount the BLTouch on the extruder carriage and connect it to the motherboard. Power on the printer and navigate to the BLTouch menu. Select “Auto Leveling” and let the sensor probe the bed. Adjust the Z-offset if needed for proper first-layer height. This process ensures precise calibration without manual intervention, improving print quality and bed adhesion.
First Print Guide
Insert the SD card with pre-sliced models. Navigate the menu to select a test file. Ensure the bed is clean and properly leveled; Load filament, start the print, and monitor the first layer for proper adhesion.
5.1. Preparing the Print File and Slicing
Download your STL file and open it in slicing software like Cura. Select the Ender 3 printer profile and adjust settings such as layer height, infill density, and support material. Ensure the print orientation optimizes material usage and print time. Slice the model and save the G-code file to an SD card. Verify the file name is compatible with the printer and check the preview to ensure proper layer adhesion and print quality.
5.2. Loading Filament and Starting the Print
Preheat the extruder and bed to the recommended temperatures for your filament. Insert the filament into the extruder, guiding it gently until it feeds through. Use the control panel to navigate to the print menu, select your G-code file, and start the print job. Monitor the initial layers to ensure proper adhesion and adjust the bed leveling if necessary. Allow the printer to operate without interruption for optimal results. Always ensure filament is loaded correctly to avoid jams or failed prints.
Maintenance and Troubleshooting
Regularly clean the print bed, lubricate moving parts, and check belt tension. Inspect the nozzle for debris and ensure proper filament flow; Address clogs promptly to avoid damage.
