How to Achieve a Dual-Color Print on Your Ender 3 S1 Pro

Are you looking to create eye-catching dual-color prints on your Ender 3 S1 Pro? In this guide, we will walk you through the process step by step. We will be using a Zodiac sign keychain as an example, showcasing how to overcome a common bug encountered during the printing process.

Steps to Achieve a Dual-Color Print:

Obtain the STL File: Begin by acquiring the STL file for the dual-color print you wish to create. This could be from a 3D print farming Patreon or any other source of your choice.
Prepare the Model in Cura Slicer:
- Open Cura slicer and import your STL file.
- Proceed to slice the model as per your preferences.
Identify the Layer for Color Change:
- Switch to the preview tab in Cura.
- Utilize the bar on the right side of the screen to determine the layer where the color transition should occur. Note down the layer number (e.g., layer 13).
Modify G-Code:
- Navigate to 'Extensions' > 'Post Processing' > 'Modify G-Code'.
- Add a script for 'Pause at Height' and input the layer number identified earlier.
- Choose 'bqm5' as the pause layer option, known for its reliable performance.
- Check the 'Park Print' box and input '0' for X and Y coordinates.
- Adjust the standby temperature according to your printing requirements.
- Optionally, include an 'm300' command for a beeping noise during the pause.
Initiate the Print:
- Load the first color filament and start the print job.
- Monitor the progress until it reaches the designated pause layer.
Changing to the Second Color:
- Once the print is paused, unload the first color filament and load the second color filament.
- Resume the print following the instructions provided.
Overcoming the Bug:
- If your Ender 3 S1 Pro firmware lacks the 'Resume' option:
  - Act as if you are going to pause the print.
  - Click 'X,' which should transition into a 'Resume' button.
  - Another workaround is to access the 'Parameter Settings,' go back, and the 'Resume' button should appear.
Complete the Print:
- Allow the print to continue with the second color.
- Once finished, admire your two-color creation!

Conclusion

Achieving a dual-color print on your Ender 3 S1 Pro can elevate your 3D printing projects. Despite encountering bugs like the missing 'Resume' option, there are effective workarounds to ensure a successful print. We hope this guide has been informative and helps you in your 3D printing journey.
