LightBurn 0.9.00 - Simulation preview, Trocen USB support, Beginner Mode, and lots more.

This release has taken significantly longer than any other to date, but it contains more new stuff than any other release too, so hopefully it's been worth the wait.

First, the big new features:

Full simulation preview window

The preview window now includes a complete motion simulator that includes acceleration and cornering speeds, a cross-hair to show the laser position, real-time playback, and playback speed control.  The device settings has a new window to let you tune the parameters to match your system. In the next release we want to pull the settings directly from your machine.

USB support for Trocen / AWC devices

This means that the TL-3120 is now supported, along with USB connections for the AWC 708c and AWC 608 controllers.

Beginner Mode

In the settings, you can now enable "Beginner Mode" to hide the more advanced cut settings and controls. It makes the software a little less scary for new users, and harder to accidentally set things - great for classroom setups and beginners alike.

Camera System Improvements

Much of the camera capture code has been rewritten. The camera lens calibration now has a special setting for fish-eye lenses which improves both ease of capture and the resulting calibration accuracy. It also gives you more usable camera area in the output. We've also added a "Capture" button to the main toolbar, and fixed a number of bugs in the alignment capture process.

Find my Laser - Automatic device setup

A common question from new users is "What kind of laser do I have?", followed by "Does LightBurn support it?" The new Find my Laser feature will automatically identify and partially configure LightBurn for use with any USB connected laser that it recognizes.

Dual Tube Support for Ruida

This is still a bit of a work in progress, but the first pass of dual tube support for Ruida controllers is included in this release.
