## Bit used
After some test with a lot of models and all possible combinations it's safe to say that >20 is BondingBox and mm3 volume the best it can.
So i used 25 just as a safe value in:
- Stanford_Bunny
- 3DBenchy
- retraction_tower

## MultiPart 3MF
Didint change them, too much trouble for small changes.
* Add read support for Google's Draco (.drc) format.
* Fix build on Linux
* Use boost instead of fstat.
* Switch to boost memory-mapped file to save RAM and potentially improve performance.
* Trim trailing whitespace.
* Initial Draco write support.
Currently always exports with 16-bit precision and speed 0 (best compression).
The back-end function does have arguments to specify them, it's just not hooked into the GUI.
* Add Draco to the About dialogue.
* Fix Linux compile (hopefully)
* Add an option to associate DRC files on Windows.
* Implement a Preferences option to set Draco position quantization bits
* Update src/slic3r/GUI/Preferences.cpp
Co-authored-by: Ian Bassi <ian.bassi@outlook.com>
* Some slight changes to ianalexis's suggestion.
* Implement a create_item_spinctrl() function for numeric inputs, and use that instead of create_item_input().
* Move "bits" to inside the spinctrl box.
* Refactor following yw4z's feedback
* Update src/slic3r/GUI/Preferences.cpp
Co-authored-by: Ian Bassi <ian.bassi@outlook.com>
* Change to 0 bits as the default setting for Draco export precision.
* Change to a lossy checkbox and a bits field with a range of 8-30.
* Proper SpinInput code from yw4z
* Revert "Proper SpinInput code from yw4z"
This reverts commit 7e9c85f31a.
* Revert "Change to a lossy checkbox and a bits field with a range of 8-30."
This reverts commit d642c9bcc0.
* Redo preferences based on SoftFever's feedback
* Refactor to minimize code duplication
* Fix padding
* Improve Draco export quality level tooltip clarity
Clarify that 0 means lossless compression (not uncompressed),
document the valid lossy range (8-30), and better explain the
tradeoff between file size and geometric detail.

Closes#11726
# Description
Removed hardcoded 0.2mm layer height.
Now it will stay in with the user process.
Also corrected several config assignments to use print_config instead of obj->config for consistency.
## Note
Didn't change PA PATTERN because i don't know if it may impact the calibration results for this specific test.
* Add overhang_reverse config to calibration routines
Set the 'overhang_reverse' configuration option to false in both calib_temp and calib_retraction functions to ensure consistent calibration behavior.
* Disable overhang_reverse in calib_pa function
Adds a line to set the 'overhang_reverse' configuration option to false when running the calib_pa function, ensuring this feature is disabled during calibration.
* Disable reverse on even for PA Tower
* Remove unncesary overhang_reverse disablers
* Update Plater.cpp
Update Plater.cpp
* Update Plater.cpp
### What was the issue?
The check that validates whether a filament is compatible with the selected build plate type was only executed for Bambu Lab printers.
Other printers skipped this entirely, even though they can also use multiple plate types with different temperature requirements.
This caused cases where:
- incompatible filament/plate combinations went unnoticed,
- users received no warning even when the bed type clearly couldn’t support the selected filament.
### What’s changed?
- The validation block extends beyond BambuLab printers.
- Now all printers get the same compatibility check:
- if a filament requires a bed temperature not supported by the chosen plate,
- Orca shows the same clear error message as it does for BBL printers.
- Show the selected filament preset name (alias if present) in bed/filament mismatch warnings instead of substituting the parent preset.
### Why this helps
- Consistent behavior across all printer brands.
- Prevents invalid filament/plate setups that could cause print failures.
- Makes plate presets more robust and predictable for custom and community printers.
### Notes
- No behavior changes for BBL printers — they keep the existing checks.
- Other printers now benefit from them too.
On linux, some users report that attempting to edit the printer
caused OrcaSlicer to hang.

* Add auto slice after changes option
Introduces a new 'Auto slice after changes' setting in Preferences, allowing OrcaSlicer to automatically re-slice when slicing-related settings change. Implements logic in Plater to schedule auto-reslicing if the option is enabled and conditions are met, and sets the default to false in AppConfig.
* Improve auto-reslice scheduling after slice cancellation
Adds a flag to track when auto-reslice should be triggered after a slicing process is cancelled. Ensures that auto-reslice is scheduled once the current slicing process completes and is not lost if a slice is cancelled mid-operation.
* Add configurable delay for auto slice after change
Introduces a new 'auto_slice_change_delay_seconds' setting to control the delay before auto slicing starts after a change. Updates AppConfig to set a default value, adds a timer and logic in Plater to handle the delay, and exposes the setting in Preferences. This allows users to group multiple edits before triggering auto slicing.
* Combine auto-reslice checkbox and delay input in preferences
Replaces separate auto-reslice and delay settings with a unified UI element in Preferences. The new function create_item_auto_reslice adds both the checkbox and delay input in a single row, improving usability and code organization.
* Move auto reslice option into Control > Behaviour
* Remove 'loop' icon from AutoSlice
* Default disable and 1 Sec
* Replace with STL to Replace with 3D file: Support STEP
Enhanced the replace logic to support STEP (.stp, .step) files, including user-configurable mesh settings and dialog, while maintaining backward compatibility with STL and other formats.
Updated the menu label and tooltips to 'Replace 3D file' for clarity.
* Update 'STL' references to '3D file' in UI and logs
Replaces user-facing text and log messages referring to 'STL' with '3D file' for broader file type support and improved clarity in the menu, status messages, and logging.
* Merge branch 'main' into remplace-with-stl
