LycheeSlicer: vanhemmat versiot ja versiohistoria

This release fixes a series of island detection bugs and resolves the FDM slicing freeze introduced, so you can get back to printing with stability. Read the changelog for the rest of the updates. Lychee Slicer 7.6.3 minor update:
Fixed — Object Deletion in Prepare Tab: Delete key no longer removes objects when triggered from the Prepare tab Object Manager.
Fixed — Resolved slicing error on the Creality Halot Sky 2022: All models now slice correctly.
Fixed — An issue where, in some cases, all plates could be deleted in the 3D view. At least one plate must now remain.

- New Authentification Process: Initial connection with Gmail and other authentication now happens directly in your browser, making the login experience more reliable.
- New Resin Printer Support - Athena II: The Athena II printer profile has been added to the printer library with optimized default resin settings.
Fixed 🐞
1. Series of Fixes on the Island Detector feature
Fixed island search bug when using multiplate because islands were not properly detected across plates.
Fixed islands being reported off-side from the actual model position.
Fixed islands moving to wrong positions after a z or x movement was applied to the model.
Fixed island detector misbehaving after selecting invisible objects.
Fixed islands being incorrectly restored from .lys project files.
Fixed incorrect island count displayed in the Export menu.
2. Fixed FDM freeze on Slicing
Filament users on 7.5.5 were hitting a freeze that prevented any slice from completing. This has been fully fixed.
Improvements ⚙️
Global Performance Optimisation: Overall performance has been improved across the board. Most notably, project files now load twice as fast on open.

Auto Support Improvements & New Printer Support. This stable release focuses on refining the new Auto Support system introduced in 7.5, making it more precise, smarter and more reliable, while also adding support for a highly requested printer. [HOTFIX 7.5.5] We fixed an issue where overhang supports were no longer working.

New Resin Printers Compatibility
- Piocreate Halot X1
Auto Support Improvements ⚙️

Improved Overhang Support System
- Added dynamic spacing based on angle
- Users can define spacing at 0° and at a maximum angle
- Added 3 new overhang support presets, automatically calculated based on supported volume

Smarter Support Placement Between Close Islands
- When two islands are closer than the support tip size, only one support is now placed
- This single support efficiently supports both islands
- Result: fewer supports, cleaner prints

Maximum Angle for Reinforcement & Stabilization
- Added a maximum angle parameter for reinforcement and stabilization supports
- Works similarly to overhang angle settings
- Gives better control over where supports are generated

Improved Reinforcement Point Placement
- Reinforcement points are now prioritized on overhang surfaces
- Leads to stronger structural support where it matters most

Mini Support Filtering
- Added a filtering system to prevent extremely small mini supports
- Reduces unnecessary supports and improves print cleanliness

In Lychee Slicer 7.4.2, we’re delivering your most requested feature: Multiplate. Now you can manage complex projects with multiple build plates all within a single scene. This update also brings easier model duplication, new printer support, and expanded resin compatibility to simplify your workflow. HotFix Update (7.4.2): Fixed ViewCube functionality and improved Saved Views accuracy for correct plate snapping and positioning.

New 🎉⚙️
New Feature: MultiPlates

Multiplate lets you manage and prepare multiple build plates in a single project. You can now organize your entire print workflow in one workspace , whether you're working with resin or FDM. Key Highlights:
- Add up to 49 plates manually - Perfect for batch printing, multi-model setups, and complex projects
- Adding Plates: Add a new plate directly from: The 3D view - The object and plate list
- The “Outside” Plate: The Outside plate automatically collects objects from a plate that was deleted. It does not include all objects outside a build plate (unlike Bambu Studio). So an object may appear outside the plate in the 3D view but not be listed in the Outside plate. If you delete a plate containing objects, those objects will move to the “Outside” plate.
- Quick Selection Shortcut: Select all objects on the active plate using `Ctrl + Shift + A` Note: This shortcut currently does not select supports in Prepare mode — that’s coming in the next release!
- Moving Objects Between Plates using: Right-click in the object list - Right-click in the 3D view - The gizmo - Directly editing position values in the input fields
Lite Users Can: Edit a plate - Rename a plate - Hide a plate - Select a plate for slicing
✅ Available on: Lychee Slicer Lite (restricted), Lychee Slicer Plus, Lychee Library, Trial plans
New Shortcut: Copy & Paste (Ctrl + C / Ctrl + V)
It’s a small but super useful shortcut that lets you quickly duplicate models using standard keyboard commands.
- In Layout: Copy and paste objects within the same plate or across multiple plates
- In Prepare: Copy and paste hole settings, hollow blockers, and supports
- You can also copy an object from one scene and paste it into a new scene
✅ Available on: Lychee Slicer Lite (restricted), Lychee Slicer Plus, Lychee Library, Trial plans

This new major version includes updates to both the Lychee Resin and Filament Slicers and is jam-packed with new features, bug fixes, and support for new Resin and Filament printers.

New Feature
- [Pro Resin] Grid Supports: You can now turn on Grid Supports and prepare your models more efficiently with better parenting and bracings. This feature will help you achieve a better support structure and print quality and save more resin.
- [Pro Resin] Bracing Editor: Access an advanced editor to create your bracing presets.
- [Pro Filament] Surface Ironing: Regular and fast ironing are available to produce smooth surfaces on flat surfaces.
- [Pro Filament] Boolean Tool: use objects or 3D models to create subtractions and/or additions performed during the slicing process.
- [Filament] Angle Seams placement: Change the layer position and seam placement at sharp angles of your models, making them less visible.
improvements and optimizations
- [Pro Resin] Inline Supports can now be used with the Mirror Mode
- [Pro Resin] Painting Supports can now be used with the Mirror Mode
- [Resin] Mirror Supports are now improved since you can choose to use the feature on the center of the scene (the world) or the center and orientation of the object (local)
- [Pro Resin] Addition of Grid Supports to the Batch Tool
- [Pro Resin] Addition of a “Generate Batch Report” checkbox in the Batch Tool
- [Filament] We improved our FDM supports! We added a new support shape (cylinder) and a better zone selection when using Support At Slice. A raft is now added under the supports.

- Lots of fixed bugs and improvements on the Grid Supports (thanks to all of your feedback during this Public Beta)
- Multiple fixes when the User Interface was crashing
- Files that were not found when loading LYT or LYS
