PrusaSlicer 2.4.0-beta2

PrusaSlicer PrusaSlicer 2.4.0-beta2

Summary

This is the second beta release of PrusaSlicer 2.4.0, following 2.4.0-alpha1 ↗, 2.4.0-alpha2 ↗, 2.4.0-alpha3 ↗ and 2.4.0-beta1 ↗. This beta mostly fixes bugs found in beta1.

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.

Windows dark mode improvements

As mentioned in beta1 change log, we continued in Windows dark mode implementation. This was a tedious work given the lack of support provided by Windows API, but we managed to skin most widgets and got reasonably nice look on both Windows 10 and 11 in the end. Main improvements with respect to 2.4.0-beta1 are included in github.com/prusa3d/wxWidgets/commit/4b7588eb0fec2d3e9b48e8b1d27e347ba91011a8: ↗

• Skinned title bar for most dialogs and frames
• Redrawn Spin controls
• Skinned tooltips, scroll bars, menus, and list boxes

We also improved dark mode version of "Change volume type" dialog and PrintHost dialogs.

Other improvements with respect to PrusaSlicer 2.4.0-beta1

• When copying system info from About->System Info dialog into clipboard, OpenGL extensions are newly enclosed in `

` tag so they are wrapped when inserted into a github issue #6830

• Conversion from inches/meters to mm can now be done for all loaded objects at once, so the user does not have to confirm each object separately.
• New functions in custom G-Code macro language: round(value) (rounds to integer), digits(value, numdigits, numdecimals) (rounds to numdigits and numdecimals, left filled with spaces), zdigits(value, numdigits, numdecimals) (same as digits(...), only left filled with zeros) #3472
• New placeholder parser values for output file name template: {numobjects} (number of printable objects on the plater), {numinstances} (number of all printable instances on the plater) #2735 #3339 #4607
• When selecting SLA support points by the selection rectangle, even points that are slightly obscured by the object are selected. Until now, the center of the visualized sphere had to be visible, and it sometimes hid behind even very tiny bumps on the object.
• When running 32-bit build of PrusaSlicer on 64-bit operating system, the user is instructed to download the correct version. While such application will run, it will be slower and will easily exhaust memory.
• Fixed a crash when uploading G-Code to a print host for the second time #7170
• When PrusaSlicer detects there is a more recent configuration folder than the one it is about to use (such as an alpha/beta specific folder), the user is asked if he/she wants to copy that configuration into the current folder. A configuration snapshot is taken in case there is something that would be overwritten.
• Added a "Start printing after upload" checkbox for Repetier server (#5351, thanks @scott0122)
• Sliders presented in the in-scene dialogs always allowed to type in the required value after Ctrl+mouse click. Because this useful feature was too hidden, we now show a small button to the right of each slider to switch it into this mode:

• SLA material color can now be specified in Material Settings. The color is used for visualization in the scene and is also shown in the right panel combo box. Until now, the last FDM filament color was used.
• Windows specific: When PrusaSlicer was downloaded from the Drivers bundle and installed using the installer, the created desktop shortcut launched external updater application instead of PrusaSlicer. The updater checked updates online, notified the user when a newer version was found and then started PrusaSlicer. The drawback was that command-line arguments were not correctly passed. This was now improved by switching the order: PrusaSlicer now runs the updater after it starts. This only happens when 'Check for application updates' is checked in Preferences and the built-in notification about the same thing is supressed in that case.
• In-scene dialog widgets now accept Numpad Enter (until now, only Enter was accepted)
• Shape Gallery dialog can now be closed by pressing Esc
• Linux specific: Extruder colors in the right panel can be changed by clicking the cog wheel to the right of the respective filament preset #6759
• When uploading G-Code to print host, the confirmation dialog now has an "Upload and Print" button (instead of a checkbox)
• Changing purge volumes in multi material project did not mark project as unsaved #7265
• Minimum diameter of the brush in the multi-material painting gizmo was reduced to 0.1 mm #7108
• Configuration Wizard: when adding a printer profile with no default filament/material profile, the dialog is shown informing the user that one should be selected manually
• When custom extrusion visibility is supressed in Preview, they are not taken into account when 'Volumetric Flow' view is shown. The scaling of the color palette is therefore more appropriate #7066
• Context menu in the right panel now shows even when right clicking the name of the respective part, not just the 'Editing' column #7270
• SLA material expansion correction can now be set independently for all three axes
• Increased translation speed maximum in 3D connexion dialog to 30 (#3385)
• 'Scale to print volume' now works with circular beds
• When color changes are added using the vertical slider in Preview, the colors are newly chosen randomly. Until now, a fixed predefined sequence of colors was used, leading to issues when the color changes were not added in order).
• Out-of-bed detection was refactored and is now faster
• Support generator now merges bottom contacts, top contacts and interface layers where possible (always possible with soluble supports, with non-soluble supports it is only possible when they are extruded without bridging and have the same layer height). This removes thin loops of interfaces that were sometimes generated with complex geometries and should generally result it nicer support interfaces.
• Added experimental filtering of propagated support columns to two extrusions, overlapping by maximum 20%. This filtering step will remove spurious columns that do not support anything, but it may also remove supports supporting tiny islands (which would likely not be printable anyway without user intervention, such as extending the supported area by painting).
