This release is a hotfix based on the V2.5.3 Public Release, primarily addressing an issue in which the P2S nozzle temperature would not cool down properly after printing. Since delivering this fix through a preset update could affect existing presets for some users on V2.5.0, it is instead released as V2.6.0 to minimize the impact on existing users.
If you are using a P2S and your current Studio version is V2.5.3, we recommend upgrading to this version as soon as possible to avoid this issue.

Statement on the Color Mixing Feature
After receiving feedback from the community, we re-examined the implementation and code paths of the current version. During development of this feature, we evaluated multiple color-mixing prediction approaches, including the RGB mixing approach and Full Spectrum’s prediction implementation. Under the validation conditions at the time, we chose the RGB mixing approach that is currently used in v2.5.3.
During development, to facilitate side-by-side evaluation of different approaches, we retained implementation code under evaluation. However, we did not clearly indicate its runtime status in our previous notes. This omission caused confusion for users and the community, and we sincerely apologize.
Next, we will do two things:
- Correct the relevant wording in this release and clearly state that the current code repository contains Full Spectrum color prediction code.
- Based on further validation and more real-world feedback, move forward with formally integrating Full Spectrum’s color prediction implementation.
We thank @justinh-rahb and @ratdoux for their contributions in this area, and we also appreciate the open-source community for identifying and monitoring this issue.
Bug Fixes
- Fixed an issue where an incorrect End G-code caused the P2S nozzle temperature to not cool down properly after printing.
- Fixed an issue where A1 sliced files could not start printing in some scenarios.
- Removed several unnecessary prompts.
- Fixed an issue where H2C slices always assigned to the left nozzle in filament-saving mode.
