Ultimaker Cura 4.12.1

This is a patch release fixing two important bugs.

Bug Fixes:

• Updated Shapely to version 1.8.0 which, among other things, fixes multiplying objects on MacOS Monterey
• Fixed a bug in Lightning infill where the infill was printed multiple times under certain circumstances

Ultimaker Cura 4.12.0

For an overview of the new features in Cura 4.12, please watch our video.

Lightning infill
The new lightning infill setting lets you to print high-quality top layers but is optimized to use less material and increase your production speed. Special thanks to @rburema and @BagelOrb!

Improved top surface quality
We’ve tweaked the Monotonic setting and made adjustments throughout Ultimaker print profiles. This removes occasional scarring on models and improves top surface quality by default.

Improved horizontal print quality
Resulting in reduction of ringing, improving resolution and overall print quality.

App switcher
The new switcher provides a simpler way to navigate and use other Ultimaker applications, including Ultimaker Digital Factory, Ultimaker Marketplace, and Ultimaker 3D Printing Academy. Reporting bugs to Github is now just one click away, and it’s easier to find the application you need.

Faster start-up
We've shaved 10 seconds from Ultimaker Cura's start-up time by optimizing profile data caching.

Other new features:

• Moved the skip button to the left bottom on the sign in onboarding page and replaced with the sign in button and Create new account
• Add {material_type} and {material_name} as replacement patterns, contributed by @fieldOfView
• Update file name after saving
• Make parking optional in all "methods" of Pause at Height, contributed by @fieldOfView

Bug fixes:

• Fixed a bug when combing goes through skin on Top Surface Skin Layers
• Fixed a bug in one-at-a-time mode to not wait for initial layer bed temperature if the temperature stays the same
• Fixed a bug where there was double infill and gap filling
• Fixed a bug with monotonic ironing that causes fan speed jump to 255 for ironing pass
• Fixed an engine crash when using monotonic ordering with zigzag skin pattern
• Fixed missing commas in disallowed list for code injections, contributed by @YuvalZilber
• Fixed various typos, contributed by @luzpaz
• Fixed Filament Change Retract method
• Fixed extra microsegments inserted from Wall Overlap Computation
• Fixed inconsistent material name in the header and material selection dropdown
• Fixed scaling model down after scaling it up with tool handles
• Fixed single instance option when opening different files
• Fixed duplicating and multiplying support blockers

Ultimaker Cura 4.11.0

For an overview of the new features in Cura 4.11, please watch our video.

Monotonic ordering
The new Monotonic top/bottom order setting enables users to print parts with smoother top surfaces. This is especially useful for parts that need good aesthetics, such as visual prototypes. Or for parts that benefit from smooth surfaces, such as those that contact-sensitive components.

Complete UI refresh
Look around and you will notice that we have refreshed over 100 icons throughout Ultimaker Cura. The new icons are designed for clarity – resulting in a simpler and more informative slicing experience. Also, when scaling the Ultimaker Cura window, the UI will adapt, resulting in less visual clutter.

Improved digital library integration
Collaborative workflows using the Digital Library are now simpler. Every user with a cloud-connected Ultimaker 3D printer can access stored projects. And we have added a “Search” function to make finding files easier.

Save materials profiles to USB
Users can now save all third-party material profiles to USB. This feature is for Ultimaker S-line printers only and is especially useful for cloud-connected (or offline) printers.

Notifications for beta and plugin releases
Users can now set notification preferences to alert them to new Ultimaker Cura beta and plug-in releases.

Improve logging of errors in OAuth flow
When helping a user with log-in problems it is easier to see where the OAuth flow goes wrong.

Search in the description in the settings visibility menu
When searching in the settings visibility menu you will also search in the description of the settings.

Bug fixes:

• Fixed the setting visibility button to make it easier to click
• Inform the user that their webcam does not work because they are cloud connected
• Inform the user that their webcam does not work if the firewall is enabled
• Fixed a crash when pressing the slice button while context menu is opened
• Support non-ASCII character in the Digital Library project name
• Fixed integer underflow if print is less than half the initial layer height
• Fixed a bug where infill mesh sometimes default to having walls or skin
• Fix builds with Python 3.8, contributed by @StefanBruens
• Fix CC settings for PLA
• Fixed memory leak in Zeroconf 0.25
• Fixed connecting USB printing with detecting baud-rates, contributed by @rrrlasse
• Fixed crash when Cura crashes on exit
• Fixed a bug where the infill goes through walls
• Fixed the version upgrade of preferences file
• Fixed missing icons in deprecated icons list, contributed by @fieldOfView
• Fixed a crash in CuraEngine when the prime tower is placed in an invalid position
• Fixed a bug when user is unable to sign in on Linux if a Keyring backend is installed
• Fixed the rotation direction of the 90 degrees rotation arrows, contributed by @fieldOfView

Printer definitions, profiles and materials:

• Added SecKit SK-Tank, SK-Go printer definitions, contributed by @SecKit
• Added MP Mini Delta 2 printer definition, contributed by @PurpleHullPeas
• Added Kingroon K3P and K3PS printer definitions, contributed by @NoTaMu
• Added Eryone PLA, PLA Wood, PLA Matte and PETG 1.75mm profiles, contributed by @dapostol73
• Added BIQU BX printer definition, contributed by @looxonline
• Added FLSun Super race printer definitions, contributed by @thushan
• Added Atom 2.0 and Atom Plus printer definitions, contributed by @lin-ycv
• Added PBR 3D Gen-I printer definition, contributed by @pbr-research
• Added Creasee 3D printer definitions, contributed by @ivovk9
• Updated Strateo3D profiles, contributed by @ChronosTech
• Added Voron V0 printer definitions, contributed by @jgehrig
• Updated Liquid profiles, contributed by @alexgrigoras
• Added Farm 2 and Farm2CE printer definitions, contributed by @saliery999
• Added GooFoo and Renkforce print definitions and GooFoo materials, contributed by @goofoo3d

From version 4.11 onwards - Ultimaker Cura is only supported on operating systems actively maintained by their software manufacturer or community. This means Windows 7 and MacOS 10.13 will no longer be supported. Technically this means Ultimaker will stop testing and developing for such operating systems. However, even though it is no longer supported, there is still a high likelihood the application keeps functioning.

Want more information for Ultimaker Cura 4.9?
Read the blog post or watch the video. And don't forget to give us your feedback!

Highlights

Digital factory integration.
Now you can open files directly from Digital Library projects. Then, after preparation, quickly and easily export them back. This feature is available for all users with an Ultimaker Essentials, Professional, or Excellence subscription. Learn more

"Line type" is now the default color scheme.
When entering the Preview mode, you don't have to switch manually to line type.

Z-seam is now clearly shown in preview mode.
This ensures that you will know whether the seam will be sufficiently hidden in the end product. This will also indicate the starting point of the print.
Thanks to @BasF0 for contributing to this feature

Other Features

New 'line width' color-scheme available in preview mode.
Line-width can now be selected as a color-scheme in preview mode.
Thanks to @Ghostkeeper for contributing to this feature

Weight estimation in decimals.
This provides a more detailed idea of the amount of material used - which is especially useful for smaller prints.

Split Shell category into Walls and Top/Bottom.
The shell category was a mix of settings about walls and settings about top/bottom, splitting them into two categories makes more sense.

Post-processing script to embed screenshot in gcode.
The ability to have thumbnails embedded.
Contributed by @Gravedigger7789.

Add checkbox for Extruder Offsets.
Ability to enable or disable the extruder offsets to gcode. This will be enabled by default unless it is in the printer's def.json file.
Contributed by @RFBomb.

Cura should work properly on MacOS 'Big Sur' now, afforded by upgrades to Python (to 3.8) and Qt (to 5.15).
If you had (UX, visual, graphics card) problems, specifically on (newer) MacOS versions, like Big Sur, you should be able to use this new version.
