Known critical issues:

• Support Brim is missing if the Buildplate Adhesion is set to None. We are tracking reports here.
• Hide seam is actually not hidden and can give random results, for now changing the Seam Corner Preference to None will give better results. We are tracking reports here.
• Combing Not In Skin can result in unexpected stringing. We are tracking reports here.
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances.
• Does Cura (not) work on your OS (version)? See this article for clarification.

We are interested in having Cura and Klipper/Smooth Motion 3D printers work together more smoothly and are looking for input on how to do this. Do you have feedback on this topic? Please leave a comment on our discussion.

• Updated a typo in Japanese translations, contributed by @tamorikawa

Known critical issues:

• 🌍 Currently the translation files seem to be missing in these Beta builds. We are working on a solution so everyone can test this Beta in their preferred language. Translations are now available!
• Under certain angles, the Interlocking Structures are not effective, yet.
• The Gcode Reader Plug-in is broken since Cura 5.2, and will not load gcodes correctly yet.
• Some models have been slicing slower since Cura 5.1. #14108
• Reports have been coming in that Cura is running slow on Windows 11 #13820
• Multiple external monitors on Windows (especially if from the same brand) <a href="https://support.ultimaker.com/hc/en-us...

UltiMaker Cura 5.2.2

Introducing the UltiMaker S7
- Included support for the new UltiMaker S7

Bug fixes:

• Allow UltiMaker S7 printers to receive Material Profiles

Printer definitions, profiles and materials:

• Improved Initial Layer settings for UltiMaker S7, S5, and S3 printers
• Disabled Support Towers for UltiMaker S7, S5, and S3 printers
• Cleaned up material profiles, by removing duplicate setting segments, and unused elements
• Updated preferred quality type for all UltiMaker 3D printers

Known critical issues:

• Support is sometimes missing in detailed parts, where previous releases supported them properly (still). (Will probably not be fixed in stable. This is currently slated for 5.3)
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances. (Will probably not be fixed in stable.)
• If you are looking for an AppImage for your Linux OS we recommend using linux.AppImage. If you run into issues with launching your AppImage, we have linux-modern.AppImage ready as an alternative.

Does Cura (not) work on your OS (version)? See this article for clarification.

UltiMaker Cura 5.3.0-alpha+xmas

New tree support implementation by @ThomasRahm
This tree support uses significantly less filament, reduces printing time, and is easier to remove than our current tree supports. A number of new settings can now be applied to your tree supports, including support blocker, per-model settings, and support horizontal expansion.

The newly introduced settings are:

• Tree Support Preferred Branch Angle
• Tree Support Maximum Branch Angle
• Tree Support Diameter Increase to Model
• Tree Support Minimum Height To Model
• Tree Support Initial Layer Diameter
• Support Interface Priority
• Tree Support Limit Branch Reach
• Tree Support Optimal Branch Range
• Tree Support Rest Preference

Known Issues

• Engine crashes– Often if you try to rotate the model or move it away from the center it's resolved. If this doesn't resolve your issue we would love to get your project file to learn what's wrong
• Floating islands inside of support
• Adaptive Layerheights are not always working correctly
• Support Interface is not always working correctly
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances.
• If you are looking for an AppImage for your Linux OS we recommend using linux.AppImage. If you run into issues with launching your AppImage, we have linux-modern.AppImage ready as an alternative.
• Windows users might get a "Microsoft Defender SmartScreen preventing the installation of an unrecognized app". You can verify if the publisher "NL, Utrecht, UltiMaker, UltiMaker" and click Run anyway by clicking on the More info text.

Ultimaker Cura 5.2.1

Bug fixes:

• Restored Italian translations (was French)
• Restored simplified Chinese translations (was Czech)

Known critical issues:

• While some small fixes have been made already, the placement of the seam is still more scattered than before 5.0. (Will try to fix in stable.)
• Support is sometimes missing in detailed parts, where previous releases supported them properly (still). (Will probably not be fixed in stable. This is currently slated for 5.3)
• Multiple external monitors on Windows (especially if from the same brand) might be a problem under some circumstances. (Will probably not be fixed in stable.)
• If you are looking for an AppImage for your Linux OS we recommend using linux.AppImage. If you run into issues with launching your AppImage, we have linux-modern.AppImage ready as an alternative.

Ultimaker Cura 5.2.0

Abstract Cloud Printer Type
Online cloud printers are now grouped by type. You can slice with the ('abstract') printer type, and afterwards choose a specific printer to print with.

Support For 'Guest'-Type Accounts (In Digital Factory)
Users with the ‘Guest’ role can prepare print jobs in Ultimaker Cura and send them to the printers via Digital Factory. These print jobs will not start until they are approved by a user with an 'Member' or 'Admin' role.

More Control Over Initial Layer Flow
Three new settings: 'Initial Layer Outer Wall Flow', 'Initial Layer Inner Wall Flow', 'Initial Layer Bottom Flow', to better counteract the 'elephants foot' phenomenon.

Other new features and improvements:

• Auto-remove holes from not completely solid models in vase-mode
• Add setting for 'tree support max diameter'
• Add option to drop-down models to the build-plate individually, contributed by @Piezoid
• Added a preference to make the tray icon optional, contributed by @fieldOfView
• (Community Developer Update: Proper workflow for 'installing from source' on Windows! See our wiki.)

Bug fixes:

• Fixed a crash to do with the serialization of functions, contributed by @Piezoid
• Fixed a crash that could occur when a user has non-latin characters in their Windows username
• Another 'Tree Support Starts in Air' fix
• Restore tooltips (if available) for Intents in Recommended print settings
• Fix startup on 'Zorin OS' (a Linux flavor), contributed by @Tim453
• On Windows, (admin) users should be able to uninstall via 'Programs and Features' again
• Correct version number in Windows uninstaller
• Uninstalling didn't remove all files in Windows
• (Windows) An uninstall could only be done by the original user that installed
• Don't ignore bottom pattern when spiralizing
• Don't 'Union All' for 'Merged Meshes Overlap'
• Seam placement was not in the correct corner in some cases
• Cutting meshes with 'surface' set to 'both' cut through the mesh
• Brim lines where ordered the wrong way in some cases
• Random seam is now more random
• Correctly apply combing when spiralizing, contributed by @smartavionics
• Don't spam the user with spurious 'Cura Notification's (Windows only)
• Don't spam the logs with duplicated deprecated warnings, contributed by @Patschke
• Properly update the infill percentage in the top bar after an intent profile switch
• In certain rare situations, layers would be printed multiple times when monotonic fill was on
• Put tree support infill density at 0% by default
• Machine settings: Also save values when closing the window, not just when focus' changed
• Reduce clickable area of settings checkboxes, to prevent mis-clicks
• Fixed a crash when an unnamed tool would be accessed (possibly related to plugin use)
• Fix an issue where a plugin would crash because of a missing dependency
• Many helpful code refactors, contributed by @digitalfrost
• Fix for to-mouse zoom on screens with scaling factor, contributed by @seaniepie
• Models could not be multiplied in one-at-a-time mode
