PrusaSlicer PrusaSlicer 2.4.0-rc2


This is a second release candidate of PrusaSlicer 2.4.0, following 2.4.0-alpha1, 2.4.0-alpha2, 2.4.0-alpha3, 2.4.0-beta1, 2.4.0-beta2, 2.4.0-beta3, 2.4.0-beta4 and 2.4.0-rc. This release candidate fixes bugs found in the first release candidate. For new features in the 2.4.0 series, please read the release logs of the 2.4.0 alphas and betas.

The release candidate builds save their profiles to the same directory as the last release, however if you already tested any of the PrusaSlicer 2.4.0 alpha or beta builds, you will be offered to import the recent alpha or beta profiles.

Bugs fixed

  • Improved robustness of importing newer configuration, for example from PrusaSlicer-beta to PrusaSlicer configuration directory after transitioning from PrusaSlicer 2.4.0-beta to PrusaSlicer-2.4.0-rc.
  • Windows specific: Fixed update of non-modal presets dialog after Windows dark mode is enabled or disabled, also dark mode is now correctly updated after a newer configuration is imported #7496.
  • Improved handling of Windows dark mode and fonts during application start up for dialogs that open before the main PrusaSlicer window.
  • Fixed regression wrt. PrusaSlicer 2.4.0-rc, where "detect bridging perimeters" could not be disabled with support material enabled #7498.
  • Fixed offsetting of the "avoid crossing perimeters" paths inside an island away from the outmost perimeter. This is a regression since alpha3, where paths along holes in islands were offsetted outside their islands due to some recent refactoring. Also sometimes the offsetting failed and the print head still followed the outmost perimeter.
  • Fixed crash when switching type of a modifier to printable with circular print beds.
  • Loading modifier meshes was not properly undoable.


  • Preliminary profile for Creality Ender-3 S1, slight improvements to Ender-2 Pro #7502 thanks @pmjdebruijn.
  • Updated Anycubic i3 Mega (S) #7092 thanks @slghb.
