1.2 Bed Leveling
Bed leveling is a critical step for successful printing. Incorrect leveling can lead to the nozzle damaging the magnetic plate or the printed model not adhering properly. Follow these instructions carefully:
- Press the "1" button to initiate the leveling process.
- When the nozzle makes contact with the magnetic plate, immediately disconnect the power.
- Once the first point is leveled, reconnect power and repeat the process for buttons "2", "3", and "4".
For a visual guide, refer to the leveling section in the official product video or consult the dedicated leveling manual provided with your printer.

2. Operating Instructions
2.1 First Print
The K9 printer simplifies the printing process for beginners. To start your first print:
- Ensure the printer is properly assembled and leveled.
- Insert the TF card containing your 3D model files into the designated slot.
- Press the main print button to begin printing.
The nozzle heats up quickly, reaching 180 degrees Celsius in approximately 5 minutes, suitable for PLA material printing.

3. Maintenance
Regular maintenance ensures optimal performance and longevity of your 3D printer.
3.1 Nozzle Care
The nozzle can reach high temperatures during operation. Do not touch the nozzle with your bare hands. If there are excess filaments on the nozzle, use appropriate tools to carefully remove them after the nozzle has cooled down.
3.2 Print Bed Cleaning
Keep the magnetic print plate clean to ensure proper adhesion of printed models. Use a soft cloth and isopropyl alcohol to gently wipe the surface. The pliable nature of the base plates allows for easy removal of finished prints.
4. Troubleshooting
This section addresses common issues you might encounter with your K9 3D printer.
4.1 Printing Issues
- Model Not Sticking to Print Bed: This is often due to incorrect bed leveling. Ensure the nozzle is at the correct distance from the magnetic plate. Re-level the bed following the instructions in Section 1.2.
- Nozzle Crushing Magnetic Plate: This indicates the nozzle is too close to the print bed during leveling. Immediately disconnect power if this occurs and re-level the bed carefully.
- Filament Feeding Problems: Ensure the filament is properly loaded and not tangled. Check the print head flip cover to observe the feeding status of the extruder.
4.2 Software and File Compatibility
If you experience difficulties with 3D modeling or slicing software, or if your files are not compatible, please reach out to Easythreed technical support for guidance and resources.
