UltiMaker Cura 3.4.1

3.4.1 ==== Bug fixes

• Fixed an issue that would occasionally cause an unnecessary extra skin wall to be printed, which increased print time.
• Fixed an issue in which supports were not generated on the initial layer, because the engine expected a brim to be in place.
• Conical and tree supports are now limited within the build plate volume.
• Fixed various startup crashes, including: copying of the version folder, errors while deleting packages, storing the old files, and losing data on install.

3.4.0 ==== Toolbox The plugin browser has been remodeled into the Toolbox. Navigation now involves graphical elements such as tiles, which can be clicked for further details.

Upgradable bundled resources It is now possible to have multiple versions of bundled resources installed: the bundled version and the downloaded upgrade. If an upgrade in the form of a package is present, the bundled version will not be loaded. If it's not present, Ultimaker Cura will revert to the bundled version.

Package manager recognizes bundled resources Bundled packages are now made visible to the CuraPackageMangager. This means the resources are included by default, as well as the "wrapping" of a package, (e.g. package.json) so that the CuraPackageManger and Toolbox recognize them as being installed.

Retraction combing max distance New setting for maximum combing travel distance. Combing travel moves longer than this value will use retraction. Contributed by smartavionics.

Infill support When enabled, infill will be generated only where it is needed using a specialized support generation algorithm for the internal support structures of a part. Contributed by BagelOrb.

Print outside perimeter before holes This prioritizes outside perimeters before printing holes. By printing holes as late as possible, there is a reduced risk of travel moves dislodging them from the build plate. This setting should only have an effect if printing outer before inner walls. Contributed by smartavionics.

Disable omitting retractions in support Previous versions had no option to disable omitting retraction moves when printing supports, which could cause issues with third-party machines or materials. An option has been added to disable this. Contributed by BagelOrb.

Support wall line count Added setting to configure how many walls to print around supports. Contributed by BagelOrb.

Maximum combing resolution Combing travel moves are kept at least 1.5 mm long to prevent buffer underruns.

Avoid supports when traveling Added setting to avoid supports when performing travel moves. This minimizes the risk of the print head hitting support material.

Rewrite cross infill Experimental setting that allows you to input a path to an image to manipulate the cross infill density. This will overlay that image on your model. Contributed by BagelOrb.

Backup and restore Added functionality to backup and restore settings and profiles to cloud using the Cura Backups plugin.

Auto-select model after import User can now set preferences for the behavior of selecting a newly imported model or not.

Settings filter timeout The settings filter is triggered on enter or after a 500ms timeout when typing a setting to filter.

Event measurements Added time measurement to logs for occurrences, including startup time, file load time, number of items on the build plate when slicing, slicing time, and time and performance when moving items on the build plate, for benchmarking purposes.

Send anonymous data Disable button on the ‘Send anonymous data’ popup has changed to a ‘more info’ button, with further options to enable/disable anonymous data messages.

Configuration error assistant Detect and show potential configuration file errors to users, e.g. incorrect files and duplicate files in material or quality profiles, there are several places to check. Information is stored and communicated to the user to prevent crashing in future.

Disable ensure models are kept apart Disable "Ensure models are kept apart" by default due to to a change in preference files.

Prepare and monitor QML files Created two separate QML files for the Prepare and Monitor stages.

Hide bed temperature Option to hide bed temperature when no heated bed is present. Contributed by ngraziano.

Reprap/Marlin GCODE flavor RepRap firmware now lists values for all extruders in the "Filament used" GCODE comment. Contributed by smartavionics.
