🚀 Lightburn 2.1.02
New Features & Enhancements

Core Tools & Functionality

• Multi-Camera Support: You can now connect and utilize multiple cameras simultaneously.
• Quick Nesting: Added a native tool to tightly arrange and nest parts to save material (supports text and grouped objects).
• Font Management Dialog: Dedicated menu to browse, filter, and preview up to 4000 fonts.
• Undo History Dialog: A visual timeline of your project edits that saves and restores its position/size.
• Tangent Circle Generator: Easily create circles perfectly tangent to other geometry.
• Project Templates: Save layouts as baseline template files to speed up your workflow.
• New Scissor Tool Operations: Trimming sections or holding Shift while clipping now correctly passes segments to the active layer.
  

Laser & Device Control

• Custom G-Code Revamp: Added editable blocks for headers, G20/G21 modals, escaped text sequences, support for M73 time estimates, and custom rotary variables.
• New Protocol Support: Expanded compatibility for Duet / RepRap flavors, and FluidNC.
• Dual Laser Support: Ability to uniquely name laser sources when dual heads are enabled.
• Split Units: Control Units (how you interact with the software) are now separated from Device Units (what the machine uses natively).
  
  

🎨 User Interface & Experience Updates

• High DPI / Retina Scaling: Major overhaul to prevent text, icons, and menus from blurring or growing too large on high-resolution screens.
• Compact Workspace Layout: Reduced the physical screen footprint of the Cut Settings, Galvo Settings, and Laser/Cuts windows to leave more room for your design workspace.
• Console Themes: The console panel now inherits colors directly from your overall application theme and uses the Consolas font where available.
• Expanded Tooltips & Warnings: Added precise warning indicators for things like zero tool diameters, 3D slices with a single pass, or trying to calibrate an axis while Rotary mode is enabled.
  
  
  

🛠️ Major Bug Fixes

Geometry & Drawing Fixes

• Text Distortion: Fixed an issue where ungrouping text that was bent or wrapped along a path would distort or completely lose its bend.
• Node Editing: Resolved an undo error where click-dragging or deleting multiple nodes would fail to register correctly in the history.
• Shape Mirrors: Ungrouping an array with mirrored objects no longer strips away the mirror transform.
• Open Shapes: Tiny line removals no longer accidentally open up fully closed vector geometry.

Camera Wizard Fixes

• Fixed various memory leaks and unexpected application crashes in the New Camera Wizard.
• Corrected calibration math so the alignment pattern wizard accurately converts zone sizes between Metric and Imperial units.
• Resolved high-resolution network camera streams (like Thunder Vision) swapping network ports or failing to load.

Device Connectivity & Safety

• GRBL Adjustments: Reverted the LightBurn GRBL protocol back to a standard "GRBL-ish" format to maintain seamless machine connectivity.
• Framing Safety Locks: Users are now locked out from toggling the laser FIRE button while the laser is actively framing or busy.
• Fixed Mac-specific freezing and crashing bugs that occurred strictly during framing commands.

🔍 Easter Eggs & Miscellaneous

• Jokes in the changelog are now explicitly formatted in italics to assist the humorless.
• Significantly reduced risk of death.
• Ezcad2 Galvo Z Control will return in Avengers: Doomsday.
• Mood sensor added. Will generate more bugs when the user is angry.
• Resolved ALL ongoing legal issues from the 6th incident.
• As always, if something looks wrong in Preview, believe Preview. It has seen things.
