K2 Feature Request: Save / Clear Live First-Layer Z Offset and Apply It Automatically

Flagship K Series Creality Flagship K2 Plus & CFS

Hello Creality,

I would like to request a built-in feature for the K2 / K2 Plus to make live first-layer Z adjustment much more practical and repeatable.

Current issue

During printing, it is common to use baby stepping / live Z adjustment to fine-tune the first layer. The problem is that once the correct value is found, there is no clean built-in way to save that correction for future prints.

Because SAVE_CONFIG cannot be run while printing, the user cannot easily store the successful live Z adjustment at the exact moment the first layer is confirmed to be correct. This makes first-layer tuning less convenient than it should be.

Requested feature

Please add support for a proper saved first-layer Z offset workflow.

Suggested behavior

  1. Live adjust Z during first layer

    • User tunes the nozzle height using baby stepping or live Z offset.

  2. Save current live Z adjustment

    • Add a button or menu option such as:

      • Save First Layer Z

    • This saves the current live Z correction as a reusable stored offset.

  3. Automatically apply saved offset on future prints

    • The saved offset should be applied automatically during the next START_PRINT sequence or equivalent startup process.

  4. Clear saved offset

    • Add a second option such as:

      • Clear Saved Z Offset

    • This removes the stored correction and returns the printer to normal default behavior.

UI request

Please make these controls easy to access in the user interface, ideally:

  • near the baby stepping / live Z controls

  • not only buried inside general macro lists or advanced menus

Why this matters

This would improve:

  • first-layer consistency

  • ease of calibration

  • day-to-day usability

  • recovery from slight real-world changes in nozzle, plate, or material behavior

Right now, users can successfully find the correct Z during a print, but saving and reusing that value is awkward. A built-in save / clear workflow would make the K2 much easier to tune and use.

Ideal workflow example

  • Start a print

  • Adjust live Z during the first layer

  • Press Save First Layer Z

  • Printer stores that correction

  • Future prints automatically use it

  • Press Clear Saved Z Offset any time when a reset is needed

This would be a very useful quality-of-life improvement for K2 users.

Thank you for considering this request.
