Slic3r Prusa Edition Slic3r 1.31.3 - Prusa Edition

Summary:

This is the Slic3r 1.31.3 - Prusa Edition release. This release mainly fixes issues introduced in the 1.31.2 release. Also some long standing stability issues of the Windows 64bit builds were resolved.

This release contains following bug fixes:

Thanks to @flannelhead, @CReimer, @Sebastianv650, @voodoo-bravo, @mgroel and @MartinMajewski for their precious help.

New features:

  • A "single layer only" checkbox has been added to the 3D path preview. If selected, the bottom/top layer sliders will be synchronized and only a single layer will be displayed at a time. The checkbox may be toggled with a S key (Synchronize).
  • In the 3D path preview, the U / D keys are used to set the last layer displayed. Newly, if the U / D keys are pressed with a shift key, a single layer only is displayed and shifted up / down.

Platform specific issues (Windows 64bit specific)

It has been found out recently, that the Windows 64bit builds compiled with the newest Strawberry Perl hang if a C++ exception is catched and converted into a Perl exception. See github.com/alexrj/Slic3r/issues/3561 ↗ for details. The latest Strawberry Perl 64bit known to work is quite an outdated 5.18.4.1. This is an unfortunate situation as Slic3r relied on the C++ / Perl exceptions for various validation tasks. Namely, Slic3r hanged when trying to inform the user, that a model does not fit the print bed, or that a sequential print is not possible for some reason.

An automatic test case has been added to Slic3r Prusa Edition to detect the buggy Perl: If using a broken Strawberry Perl, the build will rightly hang on a new test case t\22_exception.t (see github.com/prusa3d/Slic3r/issues/25 ↗ for comments and screenshots).

To avoid this problem, one can compile Slic3r using an outdated Strawberry Perl 5.18.4.1. Also Slic3r Prusa Edition has been modified to avoid most if not all of the hang ups by not using the C++ exceptions for validation, but some cases may have slipped under our radar. To compile Slic3r on a broken Strawberry Perl, please set an environment variable

set SLIC3RHASBROKEN_CROAK=1

before running Build.PL. In that case the t\22_exception.t test will be skipped. Also Slic3r will show an error message and die in the cases, where it would hang before. This should not happen as the exceptions issued by the older Slic3r were converted into harmless return values, but if you nevertheless experience an error message "Closing the application", please add an issue to this project "Issues" section. The attached Windows 64bit build has been built with a "broken" Strawberry Perl.
