5. Setup
5.1 Unpacking and Placement
- Carefully remove the printer from its packaging.
- Place the printer on a stable, level surface in a well-ventilated area.
- Remove any protective films or packing materials.
5.2 Power Connection
- Connect the power adapter to the printer's power input port.
- Plug the power adapter into a suitable electrical outlet.
5.3 Filament Loading
- Mount the provided 0.5kg PLA filament spool onto the side filament holder.
- Trim the end of the filament to a sharp angle.
- On the LCD screen, navigate to the filament loading option.
- Insert the filament into the extruder's input hole. The printer will automatically pull the filament through once the nozzle reaches the correct temperature.
- Wait for a steady stream of filament to extrude from the nozzle, indicating successful loading.

5.4 Installing the 1KG Filament Holder (Optional)
If you wish to use a 1KG filament spool, you can print and attach a larger filament holder. The necessary model file is typically provided on the included TF card or available for download from the manufacturer's website.

Image Description: This image displays a four-panel guide for installing a 1KG filament holder. The top-left panel shows the 3D printed components of the holder. The top-right panel shows the printer with the printed holder attached. The bottom-left panel shows a 1KG filament spool. The bottom-right panel shows the printer with the 1KG spool mounted on the newly installed holder. Text instructions below the panels read: '1. Print the provided model file using your 3D printer. 2. Attach the printed model to the consumables bracket. 3. Enjoy the convenience of using 1KG consumables with this lightweight holder. For printing instructions, visit A+.'
6. Operating Instructions
6.1 Powering On/Off
- To Power On: Press the power button located on the printer. The LCD screen will light up.
- To Power Off: Press and hold the power button until the printer shuts down, or use the power switch if available.
6.2 Auto-Leveling
The Geeetech M1 Mini features 16-point full-auto leveling. This process ensures the print bed is correctly calibrated for optimal adhesion and print quality.
- Ensure the print bed is clean and free of debris.
- From the main menu on the LCD screen, select the 'Auto-Level' or 'Leveling' option.
- The printer will automatically move the print head to various points on the bed to measure and adjust.
- Wait for the process to complete. No manual intervention is required.

Insets highlight 'High-brightness Lighting' with an LED icon, 'Efficient Heat Dissipation' showing internal cooling fans, 'Fully Auto-Leveling' depicting the print head probing the bed, and 'Filament Break Detection' illustrating a sensor detecting a broken filament.
6.3 Starting a Print
- Prepare your 3D model using slicing software on your computer and save it to the TF card in a compatible format (e.g., .gcode).
- Insert the TF card into the designated slot on the printer.
- On the LCD screen, navigate to 'Print from TF Card' or a similar option.
- Select the desired model file from the list.
- Confirm your selection to begin the printing process. The printer will preheat the nozzle and bed, then start printing.
6.4 Monitoring and Pausing a Print
- The LCD screen will display print progress, temperature, and other relevant information.
- To pause a print, select the 'Pause' option from the menu. To resume, select 'Resume'.
- In case of filament run-out or breakage, the printer features filament break detection and will pause automatically. Load new filament and resume the print.
6.5 Removing a Print
- Once the print is complete, allow the print bed and nozzle to cool down.
- Carefully remove the flexible magnetic PEI print plate from the printer.
- Gently flex the print plate to detach the printed model. Use a spatula if necessary, but avoid excessive force to prevent damage to the plate or model.
- Reattach the print plate to the printer.
7. Maintenance
7.1 Cleaning the Print Bed
- After each print, ensure the print bed is clean. Use a soft cloth and isopropyl alcohol to wipe away any residue.
- Avoid using abrasive materials that could scratch the PEI surface.
7.2 Nozzle Maintenance
- If you notice clogs or poor extrusion, use the provided nozzle cleaning needle to clear the nozzle while it is heated.
- Periodically inspect the nozzle for wear. A worn nozzle can affect print quality and may need replacement.
7.3 General Cleaning
- Keep the printer free of dust and filament debris. Use a soft brush or compressed air.
- Ensure the linear rails and lead screws are clean and lightly lubricated if necessary (refer to manufacturer guidelines for lubricant type).
8. Troubleshooting
- Poor First Layer Adhesion:
- Ensure the print bed is clean.
- Verify auto-leveling has been performed correctly.
- Adjust print bed temperature in slicing software if necessary.
- Filament Not Extruding:
- Check if the filament is properly loaded and not tangled.
- Clean the nozzle for clogs.
- Ensure the nozzle is at the correct temperature for the filament type.
- Print Quality Issues (e.g., stringing, layer shifts):
- Check filament quality and ensure it is dry.
- Review slicing software settings (retraction, print speed, cooling).
- Ensure the printer is on a stable surface to prevent vibrations.
- Printer Not Powering On:
- Verify the power adapter is securely connected to both the printer and the power outlet.
- Check the power outlet with another device.
