5. Eix X: Controls the left and right movement of the print head.
6. Capçal d'impressió: Houses the extruder and nozzle, responsible for melting and depositing filament.
7. Portafilaments: Supports the filament spool during printing.

5. Instruccions de configuració

The K9 printer is designed for quick and easy assembly, typically within 5 minutes, thanks to its smart snap design.

Modular parts allow for complete assembly in minutes.

Passos de muntatge:

1. Refer to the included assembly guide or video tutorial on the TF card for detailed visual instructions.
2. Connect the X, Y, and Z axis modules to the Control Box Base using the snap-fit mechanism. Ensure they are securely in place.
3. Attach the Print Head to the X-axis assembly.
4. Place the Printing Platform onto the Y-axis.
5. Mount the Filament Holder to the designated slot on the printer frame.
6. Connect all necessary cables as indicated in the assembly guide.
7. Connecteu l'adaptador de corrent.

Software Setup and Printing Workflow:

Understanding the workflow for preparing your 3D models for printing is crucial. The K9 printer uses Gcode files for printing. Depending on your experience level, there are different approaches:

Workflow for new 3D printer users, from children to advanced levels.

• Children Level: Download pre-sliced Gcode 3D models from webllocs com www.toy123d.com. Save the Gcode file to the TF card, insert the TF card into the 3D printer, and initiate printing.
• Entry Level: Download STL format 3D models from the internet. Use the Easyware slicer software (provided on TF card) to convert the STL file to Gcode format. Save the Gcode to the TF card, insert it into the printer, and print.
• Intermediate Level: Download STL format 3D models. Use CURA slicer software (compatible with K9) to convert the STL file to Gcode format. Save the Gcode to the TF card, insert it into the printer, and print.
• Advanced Level: Create your own 3D models using modeling software (e.g., E3Dmagic). Save the model as an STL format file. Use CURA or Easyware slicer software to convert the STL to Gcode format. Save the Gcode to the TF card, insert it into the printer, and print.

Nota: The included TF card contains the user manual, operation video tutorials, and necessary software (Easyware K9) to assist you.

6. Instruccions de funcionament

Carregant el filament:

1. Col·loqueu el carrete de filament al portafilaments.
2. Gently feed the filament into the extruder's input hole until it reaches the nozzle.
3. Preheat the extruder to the recommended temperature for PLA (180-230℃).
4. Once heated, manually push the filament through the extruder until it starts coming out of the nozzle smoothly.

Impressió amb una sola tecla:

The K9 printer simplifies the printing process with its one-key printing feature.

1. Ensure your Gcode file is saved on the TF card and inserted into the printer.
2. Press the designated 'Print' button (often indicated by a play symbol) on the control box.
3. The printer will automatically begin the printing process.

Monitoring Prints:

The print head features a flip cover design, allowing for easy observation of the filament feeding status during printing.

The print head flip cover allows for easy monitoring of filament flow.

Slicer and Modeling Software:

The EasyThreed K9 is compatible with various software for preparing and creating models:

• Programari Slicer: Easyware K9 (self-developed, ideal for beginners and kids), CURA, Simplify3D. These programs convert 3D models into printable Gcode instructions.
• Modeling Software: E3Dmagic (self-developed, easy modeling for kids). This software allows users to design their own 3D models.

7. Manteniment

Regular maintenance ensures the longevity and optimal performance of your 3D printer. The modular design of the K9 facilitates easy replacement of parts if needed.

Modular design for convenient maintenance and part replacement.

• Neteja: Regularly clean the print platform and nozzle area to remove any filament residue or debris. Use a soft cloth for the platform and a small brush for the nozzle.
• Emmagatzematge de filaments: Store PLA filament in a cool, dry place to prevent moisture absorption, which can affect print quality.
• Lubricació: Periodically check and lightly lubricate the moving parts (rods, lead screws) with appropriate lubricant to ensure smooth operation.
• Inspecció de broquets: Inspect the nozzle for wear or clogs. A worn or clogged nozzle can lead to poor print quality and may need replacement.

8. Solució De Problemes

Aquí teniu alguns problemes comuns i possibles solucions:

• Print Not Sticking to Platform:
  • Ensure the print platform is clean and free of grease or dust.
  • Verify that the first layer height and bed leveling are correctly set in your slicer software.
  • Consider using an adhesive (e.g., glue stick) on the print platform for better adhesion.
• Filament sense extrusió:
  • Comproveu si el filament està correctament carregat i no s'ha enredat.
  • Ensure the extruder temperature is appropriate for PLA (180-230℃).
  • The nozzle might be clogged. Try manually pushing filament through or performing a cold pull.
• Poor Print Quality (e.g., stringing, rough surfaces):
  • Adjust print speed (10-40mm/s is recommended).
  • Check filament quality; old or moist filament can cause issues.
  • Review slicer settings for retraction, layer height (0.1-0.4mm), and cooling.
• La impressora no respon:
  • Ensure the power adapter is securely connected and the printer is turned on.
  • Verify the TF card is inserted correctly and contains a valid Gcode file.
  • If connected via USB, ensure the correct drivers are installed and the software recognizes the printer.
