PrusaSlicer PrusaSlicer 2.2.0-beta

Summary

This is a first beta release of PrusaSlicer 2.2.0, following releases of 2.2.0-alpha4 ↗, non-public 2.2.0-alpha3, alpha2 ↗ and alpha1 ↗. This release mainly fixes bugs found in the previous alphas. See the respective change logs of the 2.2.0 alphas for all the new features, improvements and bugfixes in the 2.2.0 series.

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

Translations

• Korean translation has been updated by @ulsanether
• Most translations were updated to cover new texts related to new features in version 2.2.0. Japanese translation is still pending.

Improvements with respect to PrusaSlicer 2.2.0-alpha4

• Sliced Info dialog now shows estimated times with precision to minutes, not seconds. This should make the info easier to read.
• Export to STL function now exports hollowed / drilled mesh if the mesh is already hollowed / drilled at the time of export. (#3643)
• Keyboard shortcuts dialog (Help->Keyboard shortcuts) has been divided into several sections to accommodate all new shortcuts.
• Sliced Info dialog no more shows weight and cost if the unit cost or density are set to zero.
• It is newly possible to change extruders for multiple objects/parts at once by group-selection and a right mouse click.
• Elephant foot compensation is now also available in SLA mode. It is configurable under Printer Settings->General->Corrections. The Elephant foot compensation is applied over "faded_layers", where the compensation is maximum at the 1st layer and it fades to zero linearly.
• Time estimates for inserted print pauses are newly shown in 'Sliced Info' dialog (only times of color changes were included until now). (#3544)

Bugs fixed with respect to PrusaSlicer 2.2.0-alpha4

• Fixed missing layers when wipe into object/infill feature was active (regression issue that was introduced in 2.2.0-alpha4) (#3637)
• Fixed a crash when the print was empty after slicing. An error message is now shown instead. (#3632)
• Fixed regression in spiral vase after recent refactoring. Spiral vase now requires reslicing of the model when enabled / disabled as different slicing strategy is newly used for the spiral vase mode to always produce a single contour per layer.
• Camera movement in FDM mode is again limited so the zenith angle cannot grow over 90 degrees. This limit was accidentally removed in 2.2.0-alpha4.
• Improved reliability of SLA Hollowing for models that already contain cavities. (#3622)
• Fixed occasional crashes when slicing a model with FDM supports enabled (bug introduced in alpha4).
• ColorPrint slider actions are no more accessible when sequential printing is active as we do not support ColorPrint in sequential mode.
• Fixed regression in G-code export: Filament statistics in the G-code were missing several newlines.
• Fixed a crash when selecting multiple extruders by a right mouse click. (#3657)
• Fixed a regression where the brim paths were printed in random order in case the brim intersects skirt. (#3634)
• Fixed a Config wizard issue, where the Config wizard workflow could not be finished in case that only Custom printer was added, but no vendor pre-configured printer was selected.
• Fixed a regression issue in G-code generator, where duplicate extrusions were placed into output G-code in certain scenarios (#3665).
• 'Hollow and drill' gizmo allowed access to Expert parameters in non-Expert mode.
• It was possible to add multi-part object in SLA mode, which is not supported.
• Setting extrusion width to incorrect value sometimes led to application crash. (#3482)
• Fixed a regression issue after removing the Print Host information from the 3MF and AMF poject file due to privacy issues. Opening saved project cleared Print Host settings. The issue has been solved by loading the Print Host settings from user profile if it is not defined in the 3MF/AMF project file. (#3655, #3244)
• Fixed a bug in the new "Minimal thickness of solid top/bottom infill" feature. Top / bottom layers were generated even if their number was set to zero and their minimal required thickness was non-zero. Now the minimal thickness is ignored in this case.
• Placeholders in custom G-codes did not respect filament overrides. (#3649)
• Fixed a file export verification check introduced in PrusaSlicer-2.2.0-alpha2. Verification check was failing when exporting to external drive into path containing non-ASCII characters.
• Linux specific: reordering objects/parts in the object list irretrievably hid any settings, parts and instances that the dragged entity had assigned.
• Clipping plane in SLA support points editing mode ignored any drained holes that the object had (i.e. they were shown even if they shouldn't be).
• When editing SLA support points and switching to a different object, the previously selected object was not hidden (the bug was introduced in alpha4).
• Wipe into object was not working in certain cases (regression issue introduced in alpha4) (29086aa00bc28a0cccd68fefc11e722b1f023f0d)
• Unsaved changes in Filament profile were lost without user consent when Print profile was switched. (#3675)
• Adding an SLA drain hole and then selecting it showed incorrect depth value on the respective slider.
