Brand new slicer

Slicer with collision detection, advanced arranging, improved tipping, and lots of performance improvements.

Fix version check

1.2.5.20170430

update version number

Add fan_always_on option for Slic3r

This adds the fan_always_on flag that Slic3r uses.

Bug fix for collision detection

Fixed a bug where collision detection didn't notice a change after auto-arranging.

Colliding models in red

Collision detection. Models that overlap or stick out of the print volume will be shown in red.

Auto arrange and multiple STL files

With this release, auto arrange platform and multiple STL files.

Disable Slice button when unavailable

Previous, the Slice button was available for pressing even when slicing isn't possible. For example, you can't slice while printing because the slicing is CPU intensive and OctoPrint won't let you do it while you print.

With this release, we detect this and disable the slice button. And now, if there's a error in any part of the slicing process, a notification will appear on the browser.

This fixes kennethjiang#17 .

Better Slic3r support and temporary STL files

Better Slic3r support

Previously, the support for Slic3r wasn't very good. Parameters that are supported by cura but not Slic3r are missing. With this version, only relevant parameters are shown. The Slic3r version used was Prusa Edition so different versions of Slic3r might behave differently.

Temporary STL files

Previously, when slicing, if you rotated or resized your model, those change would overwrite the original STL. Now, the original STL is untouched and if there are modifications to the model, those changes are saved in a temporary file for slicing.
