UltiMaker Cura 5.9.0

New features and improvements:

Scarf seam settings

New settings have been added in experimental that let you turn your Z seam into a scarf seam.

• Scarf Seam Length Determines the length of the scarf seam, a seam type that should make the Z seam less visible.
• Scarf Seam Start Height The ratio of the selected layer height after which the scarf seam will begin.
• Scarf Seam Split Distance Determines the length of each step in the flow change when extruding along the scarf seam. A smaller distance will result in a more precise but also more complex G-code.
• Outer Wall Start Speed Ratio This is the ratio of the top speed to start with when printing an outer wall.
• Outer Wall (start) Acceleration This is the acceleration with which to reach the top speed when printing an outer wall
• Outer Wall End Speed Ratio This is the ratio of the top speed to end with when printing an outer wall.
• Outer Wall (end) Deceleration This is the deceleration with which to end printing an outer wall.
• Outer Wall Speed Split Distance This is the maximum length of an extrusion path when splitting a longer path to apply the outer wall acceleration/deceleration. A smaller distance will create a more precise but also more verbose G-Code

Try it for yourself using the showcase model for this release!

Updated the Start and End G-code It is now possible to include conditional statements such as If/Else statements when editing the start and end G-code in your machine settings. This allows you to set up much more complex printer automation that responds to things such as the status of your printer or user input. Learn more about the possibilities on our wiki.

More Improvements:

• Introduced Build Fan Speed at Height, Build Fan Speed at Layer, and Build Volume Fan Number to control extra fans, like those controlling the build volume separately
• Significant UI speed improvements interacting with custom settings especially if your printer has multiple extruders
• Introduced an Anycolor option for the UltiMaker S and F series enabling you to print with any UltiMaker color loaded in the material station that is compatible with the printjobs. Note that it’s only compatible with the latest version of the firmware (for Factor 4 >=10.1 and for S-series >=9.0, and it does not include the UltiMaker S3)
• Added an option to Export Package for Technical Support to the help menu, it includes a project file with the settings but also the logs
• Improved the way materials are selected when using multiple extruders to print the build plate adhesion so it doesn't default to the first extruder but the best option instead.
• Improved processes so not only installers but also executables inside installers are signed for Windows
• Introduced improvements to how models and projects with large file size (500MB) slice. A message was also added to inform the user when a file size is too big to slice.
• Made it possible for multiple Engine plugins that are registered to the same slot to be used together. (Only for Modify plugins, and Plugins will be addressed alphabetically)
• Moved the Gradual Flow Engine Plug-in to CuraEngine, this also resolved slicing crashes when the plugin was used in combination with large number of smaller models that were printed at once.
• Improved and expanded the Insert at Layer Change post-processing script, contributed by @GregValiant
• Improved and expanded the Time Lapse Post Processing script, contributed by @GregValiant
• Added a registry entry to provide the option to silent uninstall on Windows, contributed by @Rotzbua

Bug fixes:

• Fixed a crash that would occur when renaming profile names that would result in changing the order of the profiles, resolves github.com/Ultimaker/Cura/issues/19522 ↗
• Fixed a bug so objects in a 3MF reload in the same position as they were saved again, contributed by @nilsiism
• Fixed an issue where overhanging walls and walls that were adjacent to overhanging walls were not printed at the correct speed
• Fixed a bug that prevented the "Sync materials with printers" page from displaying when accessed immediately after starting Cura or signing in
• Fixed a bug where reloading an updated model would not update the duplicates of the model on the build plate, resolves github.com/Ultimaker/Cura/issues/19031 ↗
• Fixed a bug that showed incompatible materials when switching between printers with a different filament diameter.
• Fixed a bug where tree support in enclosed holes has missing layers
• Made improvements in the G-codePathModify slot for Engine Plugins, contributed by @ThomasRahm
• Fixed a bug that prevented changes to the initial layer diameter from being applied properly in tree support, contributed by @ThomasRahm
• Fixed a rounding issue in the engine math, @0x5844

Bugs resolved since the Beta release

• Spiralize outer contour no longer adds unnecessary seams to the model, resolves github.com/Ultimaker/Cura/issues/19814 ↗
• When coasting is enabled the printhead no longer drops down, resolves github.com/Ultimaker/Cura/issues/19810 ↗
• Fixed coasting strategy so it's only applied to outer/inner walls, and not to skin, top-bottom, or infill
• Fixed wiping direction when printing a single wall, resolves github.com/Ultimaker/Cura/issues/19843 ↗
• Improved wiping in combination with the scarf seam, resolves github.com/Ultimaker/Cura/issues/19860 ↗
• Significantly improved the strategy for sharpest corner - smart hiding seam location combination
• Fixed a bug where long scarf seam length and short scarf seam steps would result in the seam being moved outward
• Fixed a bug where seam acceleration and deceleration around seam were not working
• Fixed a bug where infill was wrongly removed from narrow spaces, resolves github.com/Ultimaker/Cura/issues/19478 ↗
• Triple-clicking values and searches that you entered now has you select everything so you can edit it in the field similar to other desktop applications
• Updated dependencies and improved how unwanted and unused binaries are excluded from the building process.
• Added Eazao material for the new Eazao printers
• Updated the urls schemes to make them more robust when attempting to open files in Cura
• Retract before outer wall now works correctly on all layers, resolves github.com/Ultimaker/Cura/issues/19876 ↗
• Resolved top reported crashes coming in via the analyzing tool Sentry
• Removed an unwanted Z-hop when starting a new layer
• Layer starts are more visible in the print preview with the scarf seam
• Made the X to close floating and pop up windows a little bigger
• Improved the visuals of printers with a build plate texture, they now render more consistently regardless of zoom or angle of view
• The UI now displays correctly on Wayland, with this fix we noticed some performance drop compared to X11
