PrusaSlicer 2.4.1-beta3

Greetings all. 
We are happy to announce an update to PrusaSlicer. Please see the updated and improvements listed below.

Summary

This is another beta version of PrusaSlicer 2.4.1, a third patch release of PrusaSlicer 2.4.0 (beta2 was not released publicly). This patch release adds several little improvements and fixes some bugs found in the 2.4.1-beta1.

This release saves its configuration into a dedicated beta configuration folder to avoid breaking production profiles. PrusaSlicer 2.4.1-beta3 will offer to copy configuration from any older release into the beta configuration folder on the first invocation.

Improvements with respect to 2.4.1-beta1

• In 2.4.1-beta1, we added a check that G92 E0 is present in layer change G-Code when relative extruder addressing is used. This is needed to prevent error accumulation in firmware. From this version, the check is only applied for Marlin firmware, because as far as we know, other firmware flavors do not suffer from this issue. #7846
• Related to the previous improvement: our G-Code preview works by mimicking the Marlin firmware, therefore if the G92 E0 was missing and the error accumulation became visible, it would also be visible in the G-Code preview. Because only Marlin firmware suffers from this issue in reality and there is an explicit check for the G92 E0 when Marlin is selected, we have now modified the G-Code Preview so the loss of precision problem is not visualized. #4881, #5073, #6336
• Clicking 'Delete All' button to delete all currently defined G-Code substitutions is newly followed by a confirmation dialog, so it is not possible to delete the entries by mistake #7850

Bugs fixed

• Fixed wrapping of text in modal dialogs, unnecessary line breaks were sometimes present
• 'Compare presets' dialog was missing an info text about values being truncated #7852
• When a 3MF with an SLA project was loaded and there were no SLA printers installed, the presets from the 3MF should have been temporarily installed. Instead, the list of SLA materials was incorrect and possibly even empty. This is quite an old bug.
• Fixed an issue with a gap in the brim when the inner brim was used
• When the outer brim of an object was very wide, it could overflow into a hole in another object
• Saving a preset after a modification incorrectly marked the currently opened project as saved #7849
• Some settings showed confusing indeterminate labels when they were modified per object in Object Manipulation panel #7887
• Improved robustness of multi-material painting, which sometimes produced gaps in the painted area of did not propagate it deep enough into the original volume #7838, #6892
• Linux specific: Print Settings and Filament/Material Settings controls were disabled after a specific sequence of loading projects and switching between FDM and SLA mode.
• macOS specific: Cmd+M did not minimize the application as it should have. This is now fixed for Intel Macs, the problem persists on ARMs.
• Exporting a volume as STL did not take into account possible transformation (rotation and scaling) of the model. This bug was introduced in 2.4.1-beta1. #7906
• Fixed incorrectly shown cut contour in the Cut tool when cutting in SLA mode and the object was elevated because of supports

Localization

• Updated CS, DE, ES, FR, IT, and PL dictionaries
