4. Operating Instructions

The Easythreed K7/K9 printers are designed for simple operation, featuring one-key printing control.

4.1. Slicing Software

Your printer comes with Easyware K7 slicing software, which offers an auto-slice function. You can also use other compatible slicing software like CURA or Simplify3D.

• Input File Format: .Stl/obj
• Output File Format: .gcode

4.2. Printing Process

1. Prepare Model: Use the Easyware K7 software (or CURA/Simplify3D) to slice your .Stl or .obj 3D model file into a .gcode file.
2. Transfer File: Save the .gcode file onto the TF card.
3. Insert TF Card: Ensure the TF card is inserted into the printer's card slot.
4. Power On: Turn on the printer using the power switch.
5. Start Print: For K9 models, press the 'One Key Print' button. For K7 models, use the button controls to select and start your print. The printer will automatically begin the printing process.

4.3. Printing Performance

The Easythreed K7/K9 printers offer excellent printing performance with features like mute printing and precise control. They operate at a low noise level, typically below 60 dB, ensuring they won't disturb your work or sleep.

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your 3D printer.

• Clean the Nozzle: Periodically clean the nozzle to prevent clogs and ensure smooth filament extrusion. Use the provided tools or a soft brush.
• Clean the Build Platform: After each print, remove any residual filament from the build platform. A clean platform ensures good adhesion for subsequent prints.
• Check Filament Path: Ensure the filament path from the spool to the extruder is clear and free of obstructions.
• Lubricate Moving Parts: Occasionally apply a small amount of lubricant to the smooth rods and lead screws to ensure smooth movement of the print head and build platform.
• Firmware Updates: Check the Easythreed official website for any available firmware updates to improve printer performance and add new features.

6. Troubleshooting

Here are some common issues and their potential solutions:

• Filament not extruding:
  • Check if the nozzle is clogged. Clean it if necessary.
  • Ensure the extruder temperature is set correctly for PLA (180-230℃).
  • Verify that the filament is loaded correctly and not tangled.
• Print not sticking to the build platform:
  • Ensure the build platform is clean and free of grease or dust.
  • Check if the build platform is level.
  • Adjust the initial layer height or print speed in your slicing software.
• Poor print quality (e.g., layers not adhering, rough surface):
  • Check filament quality and ensure it's dry.
  • Adjust print speed, layer thickness, or temperature settings in your slicing software.
  • Ensure the printer is on a stable surface to minimize vibrations.
• Printer not responding:
  • Check all power and USB connections.
  • Restart the printer.
  • Ensure the G-code file on the TF card is not corrupted.
