PrusaSlicer 2.6.0-alpha3


This is the 2nd public alpha release of PrusaSlicer 2.6.0. It mostly fixes the most critical bugs found in previous 2.6.0-alpha2. For new features in the 2.6.0 series, please read the release log of PrusaSlicer 2.6.0-alpha2.

To let you enjoy the alpha without worries, the alpha builds save their profiles into PrusaSlicer-alpha directory, so you may use the alpha side by side with the current release without ruining your production configuration.

Improvements with respect to 2.6.0-alpha2

  • Minimal connector size in the Cut tool was reduced to 1 mm #9500
  • Icons were added to radio buttons in the Cut tool to make selection of connector type more clear.
  • Windows and Linux specific: Downloading from requires the user to allow this feature in Preferences for a specific executable. An extra dialog notifying about this is now shown on startup when the new version is first run.

Bugs fixed with respect to 2.6.0-alpha2

  • Downloader preferences options were crashing in G-Code Viewer #9496
  • Cut function did not correctly apply tolerances to pins and holes #9554
  • Fixed unintended path connections in Extra Perimeters when gap fill was applied #9480
  • Fixed occasional crashes with specific brim geometries #9513#9489#9543
  • Fixed crashes of stability alert checker, when empty print object was passed to it
  • Fixed occasional crashes when using modifier meshes #9466#9511#9518
  • Fix of a crash with sequential print and raft #9464#9509#9522
  • macOS specific: PrusaSlicer 2.6.0-alpha2 has issues starting in certain languages because of locales-related issues. A temporary workaround was implemented and the application now starts with English locales (an error message is shown on startup). The issue is being investigated further #9476
  • A validation check was added for scenarios not yet supported in the alpha: Organic supports do not work with variable layer height, Avoid crossing perimeters option and avoid crossing curled overhangs cannot be enabled together #9528
  • Contour shown in Cut tool did not show correctly when the model was scaled.

You don’t. You just run the exe file of the version you want to run.   The alpha and betas don’t really have the full installer that a full release has.
