Ultimate Guide to Creality K1 Filament Sensor

The Creality K1 Filament Sensor is a critical component for 3D printing enthusiasts, offering essential functions that enhance printing precision and efficiency. From disassembly insights to advanced modifications, this article explores various aspects related to the Creality K1 Filament Sensor to help you optimize your printing experience.

Exploring Creality K1 Filament Sensor Aspects

The Creality K1 Filament Sensor is an essential component in 3D printing. Let’s explore some aspects related to it:

  1. Disassembly and Simplicity:

    • If you’re curious about what’s inside the filament sensor, Omran Al Sayed has a helpful video where he disassembles it to reveal its simplicity. You’ll gain a better understanding of your machine and improve your printing skills. Just be cautious when opening it, as the spring-loaded parts might fly off.
    • The video is part of Omran’s series on the Creality K1, which aims to fill the gap in tutorials for this printer.
  2. Filament Sensor Relocation:

    • If you’re considering relocating the filament sensor, follow these steps:
      • Unplug the filament sensor.
      • Gently place your printer on its left side.
      • Unscrew the printer feet and the 2 screws holding the bottom panel.
      • Remove the 2 screws from the rear top of the right side panel that holds the panel to the frame.
  3. Filament Holder and Sensor v2.0:

    • Creality also offers an improved version of the filament holder and sensor (v2.0):
      • The plates are now 6 mm thick (reduced from 8 mm).
      • The coil axis is inserted 5 mm deeper.
      • Aesthetic perforations have been added.
      • The sensor mounting holes are centered.
      • The filament guide hole aligns with the sensor.
      • Print options and materials are specified for this upgrade.
  4. Filament Sensor Mod by Way2Do:

    • This mod allows you to use a side spool holder or print directly from a filament dryer, even from the back or side of the printer.
    • No need to change the filament sensor cable or make other mechanical adjustments.
    • You’ll need two M3x5 screws to mount the mod.

Advantages of Filament Runout Sensors

Filament runout sensors play a crucial role in 3D printing, especially for large prints. Let’s explore their advantages:

  1. Avoid Print Failures: Filament runout sensors detect when your printer runs out of filament. This prevents print failures due to unexpectedly empty spools. Imagine investing hours into a large print only to discover that it stopped midway because the filament ran out!

    With a sensor, you’ll be alerted in time to reload filament and continue printing.

  2. Time and Cost Savings: Filament sensors save you time and money. When a runout is detected, the printer pauses, allowing you to replace the empty spool. Once you load a new spool, printing resumes from where it left off.

    This eliminates wasted time and material, especially for lengthy prints.

  3. Prevent Clogs and Jams: Filament sensors also help prevent clogs and jams. When filament runs out, the printer stops extruding, reducing the risk of nozzle blockages. This ensures smoother printing and minimizes maintenance hassles.

  4. Compatible with Various Printers: You don’t need an expensive printer to benefit from a filament runout sensor. Even budget-friendly models like the Creality Sermoon D1 come equipped with this feature.

  • Innovative Solenoid: Ultra power-saving design prevents heat-related issues.

2. Mounting the 3DTouch Sensor

Follow these steps to mount the 3DTouch sensor on your 3D printer (specifically tested on Geeetech Prusa I3 pro B, Pro C, and Pro X):

  1. Choose a Suitable Mount: You’ll need a mount to attach the 3DTouch sensor to your printer. Ensure it fits your specific printer model.
  2. Wiring:
    • 3-pin Wiring:
      • Brown (-, GND)
      • Red (+5V)
      • Orange (control signal)
    • 2-pin Wiring:
      • Black (-, GND)
      • White (Z min)
  3. Install the Sensor:
    • Attach the 3DTouch sensor to the mount.
    • Position it near the nozzle, ensuring it won’t collide during printing.
  4. Firmware Configuration:
    • Configure your printer firmware to recognize the 3DTouch sensor.
    • Set the probe accuracy and other relevant parameters.

3. Calibration and Testing

After installation, perform the following steps:

  1. Self-Test:
    • When powered on, the push pin will operate three times to test functionality.
    • The LED light blinks if any issues are detected during self-test.
  2. Bed Leveling:
    • Use the 3DTouch to level your print bed automatically.

3D Printer Sensor Troubleshooting Guide

Troubleshooting 3D printer sensor issues can be a bit tricky, but I’m here to help. Let’s dive into some common problems related to 3D printer sensors and their potential solutions:

  1. Print Not Sticking To The Bed (First Layer Issues):

    • Symptoms:
      • The printed line is thinner than desired, sometimes turning transparent.
      • Excess filament is squished upwards at the edges of the current printing line, creating a rough surface.
      • Filament gets torn off the bed during subsequent printing lines.
    • Possible Causes and Solutions:
      • Nozzle Too Close to the Bed:
        • Adjust the nozzle-to-bed distance:
          • Tighten the 3 or 4 leveling screws of your printer.
          • Use thicker paper stock for manual bed leveling.
          • Adjust your z-offset value when using a bed leveling sensor.
        • Ensure you’re not pressing down on the bed during leveling.
  2. Filament Feeding Issues:

    • Symptoms:
      • Filament not feeding properly.
      • Extruder grinding or crushing filament.
    • Possible Solutions:
      • Check Filament Path:
        • Remove any visibly damaged regions of filament.
        • Reload the conductive filament into the 3D printer.
        • If the problem persists, disassemble and clean your 3D printer’s feeder mechanism.
        • Try reducing the tension of the feeder.
  3. Stringing and Oozing:

    • Symptoms:
      • Thin strings of filament connecting different parts of your print.
    • Possible Solutions:
      • Retraction Settings:
        • Adjust retraction settings in your slicer software.
        • Increase retraction distance and speed to minimize stringing.
        • Enable “coast” or “wipe” features if available.

Sensor Maintenance Tips

Sensor maintenance is crucial for ensuring optimal performance and accurate measurements. Whether you’re dealing with camera sensors or other types of sensors, here are some essential tips to keep them clean and functional:

  1. Camera Sensor Cleaning:

    • Regular Cleaning: Dust and debris can accumulate on camera sensors over time, leading to spots in your images. Use a soft brush or blower to remove dry dust from the sensor surface. Be gentle and avoid touching the sensor directly.
    • Wet Cleaning: If dry cleaning isn’t sufficient, consider wet cleaning using specialized sensor cleaning solutions and swabs. Follow manufacturer instructions carefully.
    • Automatic Cleaning at Shutdown: Configure your camera to run a cleaning cycle each time it powers down. This helps maintain sensor hygiene after every use.
    • Preventive Measures: Power off your camera before changing lenses to reduce static attraction to dust particles.
  2. General Sensor Maintenance:

    • Keep It Clean: Regularly remove debris and oil from sensors. Proper cleaning methods are essential for maintaining all moving parts’ functionality.
    • Calibration: Calibrate sensors periodically by comparing them to correctly functioning reference instruments.
    • Proper Storage: When not in use, store sensors carefully to prevent damage or contamination.
