Creality error code 2069 on the K1, K1 Max, and K1C is a software-side error caused by an incompatible command in the uploaded G-code file. The print aborts immediately when the printer encounters the offending instruction, and no hardware is at fault.

What the Error Means

CrealityOS rejects G-code containing the M107 P3 command — a fan-control instruction generated by older or unsupported versions of certain slicers. This command targets a fan port that does not exist in the K1-series architecture, so the firmware treats the file as invalid and stops the print to prevent unpredictable behavior. The fix is entirely on the software side: update your slicer and re-slice using the correct machine profile.

Step-by-Step Fix

1. Delete the current G-code file from the printer’s internal storage or SD card to prevent accidental reprints.
2. Update your slicer to the latest version of Creality Print, or ensure your third-party slicer (Orca Slicer, Bambu Studio, etc.) is current. Outdated slicer versions are the primary source of this command.
3. Select the correct machine profile. In your slicer, choose the K1, K1 Max, or K1C profile that matches your hardware. Using a generic or mismatched profile can introduce incompatible commands.
4. Re-slice the model and export a fresh G-code file.
5. Verify the output before uploading. Open the exported .gcode file in a text editor and use Find (Ctrl+F) to search for M107 P3. If the string does not appear, the file is clean.
6. Upload the corrected G-code to the printer and start the print normally.

Parts Required

No replacement parts are required for this fix — this is a software configuration issue only.

If you continue to see M107 P3 in exported files even after updating your slicer and selecting the correct profile, check whether any custom start/end G-code scripts in your slicer settings contain the command and remove it manually. Contact Creality support if the error reappears with correctly sliced files.
