LightBurn 1.4.05 - Patch release / bug fixes

If you’ve installed the 1.4.00 release, this update fixes a handful of bugs. No major feature updates or changes.

One of the biggest fixes here is for a crash that often happened after or during long sessions of node editing, often using break apart, or deleting nodes. If you have experienced this, we strongly recommend this update. We have also “back dated” this update, so anyone who was able to use 1.4.01 to 1.4.04 will also be able to install this one.

Here’s a list of what’s changed:

1.4.05:

  • Bugfix: edge case bug causing straight lines or missed lines when importing DXF spline objects

From 1.4.04

  • More decimals for material test interval when in Inches
  • SVG import automatically converts completely straight curves to lines, and removes duplicate verts
  • Resize Slots tool now highlights lines (green), curves (pink), and shape breaks (red circles) to help spot malformed art
  • Optimize Shapes tool now displays input and output line/curve counters
  • Added detection of G-Weike Cloud laser, handles Z correctly now (auto sets proper Z height based on material thickness)
  • Copy along path function now uses nearest point on path as starting point
  • Holding Shift will now axis snap measure tool when dragging measure line
  • Bugfix: Major improvements to importing of DXF SPLINE objects
  • Bugfix: bad / empty entries in Art Library could cause crash when using search

  • Bugfix: Allow cancel while generating 3DSlice data
  • Bugfix: extremely small vertex bulge values could confuse the DXF importer

  • Bugfix: Grid Array ‘variable increment’ value wasn’t always updated properly
  • Bugfix: Slot resizer would update scaled rectangles incorrectly
  • Bugfix: SVG style definition parser didn’t handle empty space correctly
  • Bugfix: SVG parser could crash when using grouped switch/symbols that weren’t used
  • Bugfix: DXF import could crash if an unnamed block contained inserts for unfound shapes

  • Bugfix: After changing the Min/Max frequency for galvo, the main window wouldn’t allow the new range
  • Bugfix: Disallow managing cut setting defaults when in material test generator
  • Bugfix: Handle huge steps per rotation values in rotary for galvos
  • Bugfix: Text blocks in AI files could confuse the parser

1.4.03:

  • Bugfix: Ctrl+Shift didn’t de-select shapes
  • Bugfix: Ruida Z-step per pass could fail to set scanning speed if not filling whole layer at once
  • Bugfix: Convert Move Window target location for ‘Go’ button to new units when switching
  • Bugfix: Rotary setup screen would reset “run whole shapes” settings back to default
  • Allow galvo frequency setting as low as 10hz
  • Added ‘Test’ button for Repeat Marking axis setup
  • Faster screen refresh when drawing lots of very small shapes
  • Shape Optimizer will now remove Beziers that are basically linear
  • Bugfix: weird error in PDF decompression code caused some files to not import properly or even crash
  • Bugfix: IP address selection would not show in new device setup
  • Bugfix: Door Protect on galvo could not be un-paused when triggered
  • Bugfix: UV pulse now allowed as low as 0.05ns (controller limit)
  • Bugfix: ‘Increment by’ for variable text in radial array wasn’t being picked up when changed
  • Bugfix: Nasty crash in break / break apart / convert to path interaction, often triggered when node editing
  • Bugfix: Exported SVG shapes are now sorted into layer order
