• Split Marking on EzCad3 devices, tiling along one or two page axes as a grid while any other axis holds a fixed position.
• External Axis Setup on EzCad3 lists every configured axis with a tiling or fixed position role, and refuses two rows that drive the same motor.
• EzCad3 split marking starts tiling from the worktable origin set up in EzCad3, so the first tile lands under the galvo head instead of at the home switch.
• Table shear correction for split marking cancels the seam drift of a worktable whose rails are not square to the galvo field, imported from the EzCad3 configuration and editable in Split Marking Setup and the runner window.
• External Axes Settings tab in Device Settings for EzCad3, with one control group per axis covering motor selection, step scaling, speeds, homing, position readout, jog, Home and Stop, and on the rails a move to the worktable origin.

Bug Fixes

• Typos in Quick Nest messages.
• Some Custom G-code values were unit-converted when they shouldn't have been.
• Launching and immediately closing could crash the web tool loader.
• The on-screen keyboard didn't appear when touching a number field on a tablet (Windows only).
• The 3D import dialog viewport didn't render.
• Min tabs was not always respected.
• Equations in number entry fields were parsed wrongly when using a comma vs a period.
• The dogbone tool could fail in some cases; it now uses double-precision math.
• Text could change position after copy and paste because its new width wasn't handled.
• The edit window rebuilt its render buffer constantly, including on every repaint.
• The trim tool didn't work in some cases.
• Select all shapes for an operation accidentally included shapes from other pages.
• Toggle Panel visibility didn't toggle the Pages panel.
• 3D depth maps weren't imported with an image cut setting.
• Memory leak in the cut settings editor.
• The Device Settings dialog cut off Custom G-code options.
• Framing could use the wrong origin offset.
• Custom G-code didn't use the custom header when framing.
• Reset to Default Layout didn't work.
• Network permissions were missing on macOS 27.
• Re-exported images were sometimes rotated 180 degrees.
• The Device Settings dialog could cut off or squash widgets; its minimum size and stretch policy are now set correctly.
• Newer Qt was no longer resolving host names in some cases.
• Opening a LightBurn or MillMage file from the other app showed an incorrect warning and didn't preserve pages the way importing does.
• SVG import was missing content from files using SVG 2.0 features and sized text wrongly; skew and SVG 2.0 / CSS unit types (%, em, ex, ch, q...) are now supported.
• LightBurn no longer Panic(s) at the Disco
• Number entry fields could change value randomly.
• Pause/resume sent two pause commands while streaming G-code.
• Shape Properties panel fields didn't support flexible number input, unit conversion, and formulas.
• The position readout didn't refresh after a discrete jog or work-offset change.
• 3D model rotation was wrong after switching between mouse rotation and the rotation fields.
• Tab order of controls in the 3D import dialog was wrong.
• Connection buffers could block in rare circumstances on flaky grblHAL controllers.
• PDF files with object entries split across lines weren't handled.
• PWM frequency raised to 4000 kHz. Dogs within a three-mile radius have been notified
• Print and Cut label icons didn't follow the theme colors.
• Some checkable menu options didn't show check mark icons.
• Thunder Titan controllers now get separate laser enable flags.
• The PWM frequency limit is raised to 4000 kHz.
• Units typed in upper case (MM or IN) didn't convert.
• Preview could crash after importing or opening a MillMage file.
• EzCad3 fiber marking was slow when Always Open MO was disabled. Every jump closed and reopened the master oscillator and waited the Open MO Delay, which added several milliseconds per jump. The oscillator is now opened once per job regardless of the Always Open MO setting.
• EzCad3 devices created with Find My Laser were saved with gantry simulation parameters. The protocol now supplies galvo defaults, and the Read Sim Params button is available for EzCad3 devices.
• Shape Alt-drag didn't snap properly to vertical positions.
• Sparrow and jagua-rs license details were missing.
• The REST API status didn't report job progress correctly.
• The 'Enable Laser 2 Controls' checkbox didn't look disabled when it was disabled.
• Swap X/Y Axes had no effect on Custom G-code devices.
• Z axis homing settings in Device Settings misbehaved: Enable Homing was bound to the limit switch flag instead of the homing flag, turning homing on or off didn't take effect until the dialog was reopened, and the homing direction, homing switch level, limit switch level and jog direction radio buttons could show neither option selected.
• Stepper speed and homing timeout spin boxes in Device Settings and External Axis Setup clamped imported values, silently halving a fast Z axis and capping its homing timeout.
• Framing or sending a design with split marking enabled from the main window no longer reports "No shapes in bounds".
• The frame preview for a split marking or rotary job moved the external axis using the page axis number instead of the motor port.
• EzCad3 external axis commands enabled the controller limit switch mode whenever homing was enabled, so an axis with homing but no limit switches homed away from its switch and ignored the Homing Direction setting.
• EzCad3 external axis homing used a fixed 30 second timeout instead of the go-home timeout imported from Motors.ini, aborting slow homing moves partway through.
• The steps distance of a split marking or rotary axis was not saved on EzCad3 devices and reverted to one unit each time the dialog was reopened.
• Closing or switching away from an EzCad3 device while an external axis was moving or homing blocked for up to the move timeout before the connection shut down.
• Connecting to an EzCad3 machine with Find My Laser and no config files froze.
• EzCad3 galvos didn't return to the red dot rest position after a job was stopped, skipped the rest position jump when the cached position already matched, and went to field center instead of the configured rest position at the end of a job.
• Frequency control was missing for EzCad3 devices.
• Camera overlay was never updated for negative-W alignment matrices.
• UI font scaling could enlarge the UI on low-resolution screens and crop some UI elements.
• Invalid environment variables carried over from older LightBurn versions could cause UI scaling issues.
• The Galvo Move window appeared on gantry, JCZ and BSL devices, and once shown was remembered for that device. Each Move window now decides from the device profile whether it applies, the galvo one defaults to hidden and refuses to show elsewhere, and profiles that had stored it as visible correct themselves.
• The Jog Laser Down hotkey did nothing due to a typo.
• Preview frame rate issue in the new auto camera calibration wizard.
• Editing Machine Settings could crash when the device returned errors.
• Deleting a page or undoing a page delete didn't update the list of active layers.
• 16-bit greyscale and ARGB32 images couldn't be adjusted in the image adjust dialog.
• Epilog engrave speeds just under 1% showed ?? on the machine display and ran too fast.
• Epilog CO2 fill and image layers ignored the power setting and engraved at full power.
• Docked panels overlapped and clipped their contents at large font and icon sizes.
• MOPA QPulse and Frequency support were confusing for Thunder devices; those settings are now consolidated.
• Custom G-code didn't output rotary settings in headers.
• Changing the active page refreshed twice.
• Galvo Rotary Marking and Split Marking advanced the serial number when no job was completed.
• REST API jog settings could not be changed, and invalid jog, home and override values were silently accepted.
• REST API cut settings repeated the base layer in the sub-layer list and left out sub-layer settings.
• Overcut cut short and ended off the outline on curves.
• Camera UI and thread safety improvements.
• The start point editor could show the arrow in the wrong direction on closed shapes.
• Camera settings didn't persist in preferences.
• Epilog device settings didn't match the actual device capabilities; they're now locked to match.
• Camera auto modes overrode saved manual settings.
• Depth maps from imported 3D models were invisible when the view mode was set to filled.
• Depth maps lost their image type when moved to a new layer.
• REST API omitted the first sub-layer's name and wrongly reported the Show checkbox status.
• The Window menu's Move entry showed unchecked when the Move window was docked behind another tab, and could be selected on galvo devices without a Move window, where nothing appeared.
• EzCad3 Repeat Marking only turned the rotary a fraction of a degree per step when the axis type was set to Rotating.
• Titan controllers showed a current position option they don't support.
• Camera buttons were missing from the Camera / Overlays widget.
• SVG export wrote varying line weights and incorrect line attributes.
• UI issues in connection request dialogs.
• Under certain conditions the calculation of required resolution for current font and icon size settings was incorrect, and could prompt users to change display settings when unnecessary.
• With "Require framing before start" enabled, the Start Marking foot pedal on BSL lasers started marking immediately instead of opening the framing window first.
• The external Stop Marking input on BSL lasers did not stop jobs started from the main window.
• On EzCad3 lasers, Run Continuously and Repeat in the framing window counted jobs rapidly while only marking occasionally.
• BSL split marking settings weren't saved.
• Epilog speed limits weren't clamped in the Cuts / Layers window.
• Rows in Cuts / Layers didn't resize when their height changed after linking to the material library.
