PrusaSlicer 1.37.1

Slic3r Prusa Edition Slic3r 1.37.1 - Prusa Edition

Summary:

This is the Slic3r 1.37.1 - Prusa Edition release.

This release contains the following new features:

• Prusa Multi Material: Starting with this release, all filaments active in a print will be primed at the edge of the print bed before the actual print starts. After all the filaments are primed, the printer beeps and waits for 10 seconds for the user to verify, that all the filaments are primed properly. If the priming regions interfere with the print, the printer is paused indefinitely for the user to remove the priming material before the print starts.
• A new "bridging angle override" parameter has been added to the page Print Settings->Infill->Advanced page, and the "bridging angle override" may also be assigned to a modifier mesh for a volume or a range of layers. If set to zero, the usual automatic bridge detection applies, otherwise the provided angle overrides the automatic detection.
• Object settings dialog size and position is remembered alexrj#3943, thanks to @alexrj.
• The large menu with the object parameter overrides at the Object settings dialog has been split to sub menus #3905, thanks to @alexrj.

This release contains the following bug fixes:

• Fix of a "MM incorrect extruder temperature" github.com/prusa3d/Slic3r/issues/443. ↗
• Fix of a crash on pressing +/- with no object active github.com/prusa3d/Slic3r/issues/467. ↗
• Fix of "exponentional values generated as G1 F-1.95058e+006 causing problems" github.com/prusa3d/Slic3r/issues/463. ↗
• Fix of "GLMULTISAMPLE and GLARRAYBUFFERARB messages on failed launch" github.com/alexrj/Slic3r/issues/4085. ↗
• Fix of a "Scale to Size" dialog, where a bed size has been shown 1000000x scaled.
• Fixed a libexpat compatiblity issue on Linux. Now the Linux builds are linked against the system wide dynamic libexpat instead of a static version github.com/prusa3d/Slic3r/issues/472. ↗

Following internal changes were made:

• Switched the build system for the Slic3r XS module from Perl Build.PL to CMake, thanks to @CReimer for help. Contrary to Build.PL, the CMake system detects target dependencies correctly, which makes partial rebuilds reliable. Also switching to CMake is required if we want to free Slic3r from the Perl legacy github.com/prusa3d/Slic3r/issues/420. ↗
• Switched to Perl local::lib for local compilation to prevent Slic3r polluting the system Perl installation, based on the upstream implementation by @alexrj github.com/prusa3d/Slic3r/issues/447. ↗
• Ported some bits and pieces from Perl to C++ with the goal of creating a Perl free CLI Slic3r.
• Slic3r XS module has been made UTF8 compatible with the help of the boost::nowide library, thanks to @alexrj for the implementation. Removed Perl dependencies on Encode, Encode::Locale and Unicode::Normalize.
