LightBurn 1.1.00 released - better handling of multiple lasers, SVG text importing, UI improvements, and lots of fixes

There are lots of new things in this release, so we'll cover the big ones here, then list the rest.  (for anyone anxiously awaiting the upcoming galvo/fiber release, this isn't it - not quite ready yet)

Users with multiple lasers

If you have more than one laser, and they're different types or wattages, there are new features in LightBurn that will make moving between them cleaner, and we'll be continuing to improve this in the future.  Your speed / units settings are now remembered with the laser, so switching to a CO2 from a diode will switch you from mm/min to mm/sec (or whatever you use), and auto-load your material library for the machine.  The specific windows enabled are also saved / restored, so the console window will hide for a CO2 system, and reappear for diodes.

Backup Text

If you use one machine to design, and another to run the laser, you might have run into the problem of not having the same fonts installed on the laser system, so when you load a project, the text looks wrong.  This release of LightBurn stores a copy of the generated text shape in the project file, and will use that if it can't find the font.  You can't edit the text, but for just running the file or tweaking cut settings, this will work, and should save you a few trips back to the house.

Backups & Browsers

Every once in a rare while, the preferences file in LightBurn may get corrupted.  If this happens, the prefs get reset, so it might seem that you've lost all your devices and settings.  LightBurn automatically creates backups as the prefs change, and stores the last 50, but it hasn't been obvious, or simple to find them.  In this release, you go to File > Load prefs backup, and you'll see a browser that lets you see your backups by date.  Choose the one you want and it loads it from there.

We've also done this for machine settings - Any time you change your machine settings, a backup is automatically created for those too. The backup browser  in the machine settings window will let you walk through the list and load one easily.

Shear / Skew Tool

You'll notice a new pair of control handles in the edit window - these are for skewing shapes (technically called 'Shear').

Laser Tools / Center Finder Tool

The 'Tools' menu was getting a bit long, so we've taken things that are laser specific and moved them into the new 'Laser Tools' menu.  Print and Cut, Rotary Setup, and the Camera tools are all there, along with some new ones, including the new Center Finder tool.

If you regularly work with round shapes, and need to center your work, this tool should help.  You simply follow the prompts, jogging your laser to three points around the outside of the circle, and LightBurn will calculate the center for you and move the laser there automatically.

Material Test Generator

Many of you are familiar with test grids - a grid that lets you test a range of varying settings on a new material quickly, to help you find what works.  We've added a generator for these that lets you choose which parameters to change, and their ranges, size, and more.  It also gets around the 32 layer limit in Ruida hardware, so no more having to use Power Scale.

Import Text from SVG files

In an effort to improve overall use with other software, we've added the ability to import text from SVG files.  This currently does not support embedded glyphs / fonts, but that is something we're working toward as well.

Image Adjustment Presets

The Adjust Image tool now allows you to save, export, and import presets - this makes it easy to store and re-use your favorite image adjustment settings, and makes it simple to share them with others.

Drag Handle Toggles

Since this one is among the first things you'll see, I figured I should mention it here too - we've added toggle switches to disable certain kinds of mouse actions in the edit window.

These appear in the bottom of the main display, and will let you selectively turn off the ability to move, scale, rotate, or shear shapes in the edit window.  This is similar to locking shapes, but doesn't alter your file, and affects everything at once.

You'll also notice the toggle switches are a little cleaner, and easier to read (we hope).

Notable Fixes

GCode users will notice that as long as the 'Fire' button is enabled, the default behavior of LightBurn is now framing with the laser enabled at low power, no longer requiring you to hold the Shift key.

We received reports from a handful of users about issues with the load & save windows - sometimes it worked, sometimes it didn't. This has been fixed with this release.  There were also some Mac users running LightBurn in Spanish, French, or Portuguese who weren't able to see the Rotary Setup window, and this is fixed as well.

Everything else

There's far too much to go into great detail here, so I'm going to follow with a list of all the changes, and we'll be posting a video over the next few days that walks through some of the changes as well.
