This release of LaserPost for LightBurn brings several new features and many bug fixes (thanks to a new automated testing environment that tests over 80 configurations).  

Videos have not been updated:  Current information on all settings in LaserPost 1.1 can be found in the Concise guide to LaserPost settings.  New videos will be available in the coming weeks.

New features include:

• Major rework to the coordinate space and machine orientations. Now has a Machine property to specify your LightBurn machine orientation (upper-left, upper-right, etc.) that must match your LightBurn file. The WCS coordinate should always be where you would like LightBurn to see the lower-left corner, with Z pointing upwards and X/Y pointing towards the stock. Hint: To set WCS correctly in Setup, use “Select Z axis/plane and X axis” and select your Z line (thickness line) first and then the line you wish to be horizontal in LightBurn (then flip Z and X until they align correctly). Shout-out to ZePapou for his help in finding the WCS problem and testing the alpha releases. 
• “Use cutting mode” option on the post-property Layer mode selection. When selected, will determine the layer type (vector/raster) from the 2D Profile operation’s cutting mode (through will be “Fill” and etch will be “Line”).
• Added a “File-per-layer” grouping option, which creates one project file for each layer.
• Implemented the grouping-by-layer feature, which was missing from the prior version.
• Alignment marks are not available in an “output off” layer. Very useful when using “file-per-layer” and importing individual files to align multiple shapes accurately.
• Support for dual-laser machines that use a mirror shuttle (allows setting the “U” axis distance based on the laser). See Machine Properties to configure.
• Changed the setting for “show/hide notes” from the machine properties to post properties.

Bugs fixed include:

• Power-scale now retains the correct setting in the generated files.
• Support for documents in unit inches (used to only work with mm units)
• Improved the readability of generated comments and notes.
• Significantly reduced the size of the encoded thumbnail (about 5x smaller).
• Fixes for custom CutSetting XML and named grouping.
• Work offsets are now correctly applied.

The first stable release of LaserPost for LightBurn is now available!  There are no changes from Release Candidate 1 other than to change the version number.  A big Thank You to everyone who helped test.

This beta release of LaserPost for LightBurn brings several new features and many bug fixes. A new automated testing environment that tests over 80 configurations has helped to improve the overall quality of all releases (and found scads of bugs!)

A number of small fixes, nothing serious so it’s finally time to make our first Release Candidate!

• Posts would fail if a single circle was cut using Through Cut (and therefore using lead-in and lead-out on the operation).  The lead-in was incorrectly identified as an ellipse shape, but now it correctly resolves to a linear path.
• Some complex shapes were not closed due to slight inaccuracies in the position information from CAM.  Now supports an accuracy measurement (0.01mm) to determine if two points are close enough to be considered closed.
• Changed shape segmentation to correctly close shapes when many points are clustered together (uses hints from CAM operations on movements and prioritizes finding the largest closable shape over the smallest).
• LightBurn detects unclosed paths when using fill mode, and shows warning messages (and doesn’t render them).  LaserPost now comments out shapes that are not closed when a fill mode is set, such as when using the Through cutting mode (with lead-in/lead-out) instead of the more appropriate Etch cutting mode.
• Cleaned up some logging messages when using ‘insane’ level logging.

Lots of restructuring and bug fixes.  Now successfully generating LBRN files for some very complex models – getting very close to a release candidate!

Highlights of Beta 3:

• Refactored all code across many source files to make it easier to manage and understand the code organization, and a new (simple) build system. See the README and the release directory for how to build the software.
• Major refactor to shape generation – fixes many shape generation issues.
• Moved several shared properties to machine post properties.
• Reorganized 2D Profile post properties to be more usable.
• Fixed bug with arc, where long vs. short arc on CW/CCW was incorrect.
• Fixed bug where speed was sometimes zero.
• Changed default air setting to use settings from the tool.
• Add new notes feature to optionally only show notes when something important has been found (such as a release update).  Set as default.
• Fixed stock outline to use workspace offsets.
• Added XML encode/decode for string properties such as notes and properties.

Beta-2 of LaserPost for LightBurn is here!  No longer do you need to peek over the fence to see if the grass is greener (well, check if there is an updated version that is), as LaserPost now self-checks if a newer, shiner version is available.

• Post settings can specify how often to update (including never).  This is defaulted to hourly but will be changed to daily once at RC.
• Post settings can also specify if beta vs. stable releases should be checked.  Defaulted to beta until we have our first official, stable release.
• Adds guidance and management of extended permissions, since Fusion will warn that security approval is required to write to disk (for the time stamp) and access the Internet (to check for updates).  Disabling update checking allows for using LaserPost without providing permission.

And of course, a few bugs got whacked along the way:

• If LaserPost was used without a machine setup, the post would fail to run with an error.
• Fixed some minor issues that were causing warning messages in the log file.

First beta release of LaserPost for LightBurn.  Functionality includes:

• Post-processor options include grouping, power overrides, stock outline, and offset.
• 2D Profile operation post tab for LightBurn layer settings.
• Tool library support for power levels and air control.
• Generation of LBRN projects using complex shapes (Bezier, Ellipse).

Please send comments or post issues to let us know if you try this beta release and how it works!
