PrusaSlicer PrusaSlicer 2.3.0-rc2


This is the second (and hopefully the last) release candidate of PrusaSlicer 2.3.0, following 2.3.0-alpha1, 2.3.0-alpha2, 2.3.0-alpha3, 2.3.0-alpha4, 2.3.0-beta1, 2.3.0-beta2, 2.3.0-beta3 and 2.3.0-rc1. This release fixes bugs found in previous release candidate. For the new features in the 2.3.0 series, please read the change logs of all the alphas, betas and rc.

Unlike the alphas and the betas, the release candidate saves its profiles into PrusaSlicer directory, which is the same directory where the previous releases of PrusaSlicer (and the rc1) keep their profiles. If you were testing the PrusaSlicer 2.3.0 alphas or betas, your profiles from them would have to be manually imported into PrusaSlicer 2.3.0-rc2 by exporting and importing the Config Bundle.

Bugs fixed with respect to PrusaSlicer 2.3.0-rc1

  • Shells in Preview (when visualized) were not rendered with correct color
  • Minimal height of the object list in the right sidebar was decreased so the list does not take too much space when not needed (#5462)
  • Ironing was sometimes incorrectly not applied when infill parameters were changed before reslicing (#5410)
  • Fix of an occasional crash caused by a faulty notification (#5514)
  • Spiral vase mode would sometimes incorrectly fill in bottom of the model when slicing parameters were changed in certain order (#5528)
  • When there was an object with non-ASCII characters in the name, PrusaSlicer would suggest mangled name for the GCode when exporting.
  • Adaptive cubic infill was not generated correctly in case that infill extrusion width was expressed in percents.
  • Fixed a hard crash in a specific case when using copy-paste on objects with modifiers (#5517)
  • When switching Printer profiles in configuration tabs, currently active page was sometimes reset to General (#5531)
  • Fixed a possible crash when swiching printer profiles in configuration tabs.
  • Windows-specific: ConfigWizard mangled Unicode characters in printer names (#5422)
  • macOS-specific: When multiple PrusaSlicer instances were running, it could crash when ejecting an SD card from some of the instances (#5507). PrusaSlicer may now wrongly report the export as failed even when it in fact succeeded, but it will not crash in this scenario anymore.
  • Linux-specific: The toolbar that switches between 3D scene and Preview did not scale correctly on scaled displays with GTK3 (#5501)
  • Linux-specific: Fixed spurious G-Code Viewer crashes on startup when opened through File menu in PrusaSlicer or with a gcode filename provided through command-line (#5537, #5464). Many thanks to @hadrava who significantly helped with debugging of this issue.
  • Linux-specific: When started with a config directory generated by older versions, the application would crash in case that config contained print host credentials (#5513, #5074)
  • Linux-specific: desktop file for Linux desktop integration now assigns correct icon to G-Code Viewer instead of using one for PrusaSlicer (#5555, thanks @pmjdebruijn)


  • Fixed several issues and typos in the localizations, some even leading to a crash.
  • Updated CZ, DE, ES, FR, IT, NL and PL dictionaries
