2. Safety Information
Please read all safety instructions carefully before operating the printer to prevent injury or damage. Keep this manual for future reference.
- Moving Parts: The printer contains moving parts that can cause injury. Keep hands, hair, and clothing clear of the print head and build plate during operation.
- Hot Surfaces: The nozzle and build plate can reach high temperatures. Avoid touching these components during or immediately after printing. Allow them to cool completely before handling.
- Ventilation: Operate the printer in a well-ventilated area to dissipate any fumes from melting filament.
- Power Supply: Use only the provided power adapter. Ensure the power outlet meets the specified voltage requirements.
- Children: This product is not a toy. Children should only operate the printer under direct adult supervision.
- Filament: Use only recommended filament types. Incorrect filament can damage the printer or produce hazardous fumes.

4. Setup
The WEEFUN TINA2 Mini 3D Printer comes fully assembled for a quick and easy setup process.
4.1 Unpacking
- Carefully remove the printer from its packaging.
- Remove all protective foam and ties.
- Ensure all accessories (power adapter, filament, SD card) are present.
4.2 Power Connection
- Connect the power adapter to the printer's power port.
- Plug the power adapter into a suitable electrical outlet.
4.3 Filament Loading
- Place the filament spool onto the filament holder.
- Feed the filament into the extruder's input hole until it is gripped by the gears.
- On the printer's LCD screen, select "Load Filament" and follow the on-screen prompts. The printer will heat up and automatically feed the filament through the nozzle.

4.4 Auto-Leveling
The TINA2 features an automatic bed leveling system. No manual adjustment is required for initial setup.
- The printer will perform an auto-leveling sequence before each print to ensure optimal bed adhesion.

Figure 4.2: The auto-leveling function ensures precise first layers without manual calibration.
5. Operating Instructions
5.1 Preparing a Print File
- The printer supports G-code files. You will need a 3D modeling software and a slicer program (e.g., Cura, PrusaSlicer) to convert 3D models (.STL, .OBJ) into G-code.
- Save the G-code file to the provided SD card.

Figure 5.1: The printer supports printing via SD card or USB cable (USB cable not included).
5.2 Starting a Print
- Insert the SD card into the printer's SD card slot.
- Turn on the printer.
- Using the control knob and LCD screen, navigate to "Print from SD" and select your desired G-code file.
- The printer will begin the auto-leveling sequence, heat up, and then start printing.

5.3 Resume Printing Function
The TINA2 features a resume printing function, allowing it to continue a print from where it left off after a power outage or accidental disconnection.
- If power is interrupted during a print, simply restore power. The printer will prompt you to resume the last print.

Figure 5.3: The memory function saves filament and allows printing to resume after a sudden power outage.
5.4 Removing a Print
The flexible magnetic build plate makes removing finished prints easy.
- Once the print is complete and the build plate has cooled, gently remove the magnetic build plate from the printer.
- Flex the build plate to easily detach the printed model.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your 3D printer.
6.1 Cleaning the Build Plate
- After each print, ensure the build plate is clean and free of any filament residue. Use a soft cloth and isopropyl alcohol if necessary.
6.2 Nozzle Cleaning and Replacement
- If the nozzle becomes clogged, gently heat it to printing temperature and use a thin needle or cleaning filament to clear the obstruction.
- For severe clogs or worn nozzles, replacement may be necessary. Refer to the manufacturer's guidelines for nozzle replacement.

6.3 Lubrication
- Periodically check the Z-axis lead screw and X/Y axis rods for dust or debris. Clean and apply a small amount of lithium grease or machine oil if needed to ensure smooth movement.
7. Troubleshooting
This section addresses common issues you might encounter and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Filament not extruding | Clogged nozzle, incorrect temperature, tangled filament. | Clean the nozzle, verify print temperature settings, ensure filament spool unwinds freely. |
| Print not sticking to build plate | Build plate not clean, Z-offset too high, bed temperature too low. | Clean build plate with isopropyl alcohol, ensure auto-leveling completes, check bed temperature settings. |
| Poor print quality (layer shifting, stringing) | Loose belts, incorrect print speed, retraction settings. | Check for loose belts, adjust print speed in slicer, fine-tune retraction settings. |
| Printer not turning on | Power cable disconnected, faulty power adapter. | Ensure power cable is securely connected, try a different power outlet, contact support if issue persists. |
