Installing the Stepper Motor for Creality K1 3D Printer

Here’s a brief guide on installing the stepper motor for the Creality K1 3D printer. Please follow these steps carefully:

1. Unboxing and Initial Setup:

   • Disconnect the power cord.
   • Slide the chain in the direction indicated by the arrow to one side.
   • Remove the grey foam from the printer.

2. Slide the Extruder:

   • Follow the arrow’s direction to slide the extruder and extract the foam.

3. Assembling the Touch Screen:

   • Retrieve the touch screen from the toolbox.
   • Connect the touch screen to the flat cable extending from the base, following the instructions in Figure A.
   • Gently fit the touch screen into the designated slot on the baseplate, as illustrated in Figure B. Ensure alignment with the indicated direction to prevent any potential damage to the screen interface.

4. Additional Resources:

   • For more detailed instructions, refer to the Creality K1 User Manual available here.
   • You can also explore the Installation Helper Script for Creality K1 Series on GitHub, which provides additional customization options for your printer .

Optimizing Stepper Motor Performance

Optimizing the stepper motor performance on your Creality K1 3D printer can significantly enhance print quality and reliability. Here are some steps you can take:

1. Motor Current Settings:

   • Adjust the motor current settings to find the optimal balance between torque and heat. Too high a current can cause overheating, while too low a current may result in missed steps. Experiment with different values to find the sweet spot.
   • You can use the TMC2209 drivers for quieter operation and better thermal management. Consider using the following settings:
     • run_current: 1.4 A
     • hold_current: 1.0 A
     • sense_resistor: 0.100 Ω
     • stealthchop_threshold: 0 (disable stealthchop for cooler operation)
     • Other parameters like driver_TBL, driver_TOFF, and driver_SGTHRS can also be adjusted.

2. Motor Dampeners:

   • Stepper motor dampeners can reduce vibrations and noise. However, fitting them on the K1 can be challenging due to the press-fitted pulleys. Some users have successfully modified them to use set screws instead, resulting in smoother operation.

3. Extruder Motor:

   • The extruder motor tends to run hot and can cause issues with PLA prints. Consider upgrading to a better extruder with improved tension and filament tube connections.

4. Interpolation:

   • In Klipper or Voron documentation, it’s recommended to disable interpolation. You might want to try this setting to see if it improves performance.

5. Calibration Models:

   • Use calibration models to fine-tune your printer’s settings. Creality Print provides calibration models for the K1 Max, which can help you set up your machine more accurately.

6. Cura Settings:

   • For slicing, use Cura with appropriate settings for different filament types (PLA, ABS, PETG, TPU). A moderate speed (around 80 mm/s) often yields good results for most TPU filaments.
