Ultimaker Cura Changelog

What's new in Ultimaker Cura 5.7.1

Apr 25, 2024

Introducing the UltiMaker Factor 4:
Included support for the new UltiMaker Factor 4, the new 0.6 UltiMaker HT print core, and the new Ultimaker PPS CF material.
For an overview of the new features in the UltiMaker Factor 4, please watch our video.
Bug fixes:
Fixed a bug where support lines were printed multiple times
Printer definitions, profiles and materials:
Updated ASA, SR30, and Nylon12-CF profiles for MethodX and Method XL Printers

New in Ultimaker Cura 5.7.0 (Apr 3, 2024)

New features and improvements:
Universal Cura Project files:
Universal Cura Project files contain models and settings and can be shared with people who have different printers. They can be used on any printer and they allow you to include positional data for the models on your build plate as well as select settings.
Open print files directly from Thingiverse:
You can now open files in Cura directly from Thingiverse with a single click. You can find a “Open in Cura” button on all compatible file types which includes models that use the STL, 3MF, and OBJ file extension. Doing so will load the file into Cura just as if you had downloaded it and opened it normally with the added advantage that your downloads folder will not get clogged.

New in Ultimaker Cura 5.7.0 Alpha 0 (Jan 23, 2024)

New in Ultimaker Cura 5.6.0 (Nov 28, 2023)

New features and improvements:
Introduced the MethodX and MethodXL printers with it's materials and the option to write to .makerbot
A year after the merger of Ultimaker and MakerBot, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method X and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse
Prime tower base settings increase the stability of large prime towers:
New settings have been released that let you modify the base of your prime tower.
The new settings are:
Prime Tower Base Size
Prime Tower Base Height
Prime Tower Base Slope
Prime Tower Raft Line Spacing
You can modify these settings to help improve the reliability of your prime towers. You can also use them to calibrate how well your prime tower adheres to the build plate for increased print success, or to avoid over-adhesion that may damage your build plate.
The Start and End gcodes now accept variables and math including the variables:
Cura can now accept more start and end gcodes that include math, for example:
G0 X{prime_tower_position_x - prime_tower_size/2} Y{prime_tower_position_y-prime_tower_size/2} F6000
M109 S{material_final_print_temperature}
This hopefully also solves issues like #14111 (comment) and #16012 (comment)
Other Improvements:
Introduced the setting for Raft Line Spacing, but for the prime tower
Updated the Support Z Distance to allow for more different values, no longer only multiple layerheights, solves #6105
Bug Fixes:
Fixed a crash for some Linux users when trying to open the file menu
Bugs resolved since the Beta Release:
Introduced Balanced and Solid profiles for 1C cores to UltiMaker Method X and Method XL
Improved self-support for UltiMaker MethodX and MethodXL printers so the support extruder will not be used
The prime tower is now always enabled when the second extruder is used for the MethodX and MethodXL printers
Updated the default prime tower position so it doesn't prevent slicing for some printers
Fixed an issue where raft layers were partially printed
Slice information template variables were not available through start-end code formulas
Resolved an issue with 100% support roof for tree support, contributed by @ThomasRahm
Printer Definitions, and Community Translations:
Introduced Ender 3 V3 SE, contributed by @dim1triy
Updated bridge flows for UltiMaker PLA, TPLA and ABS to address pillowing in AA 0.8 for UltiMaker printers
Updated Spanish translation for Lightning infill, contributed by @Pelochus
Updated German translation for Laying object flat on buildplate, contributed by @gluetolf
Updated Brazilian translations, contributed by @Patola
Known Issues:
The predicted printing time for dual extrusion printjobs on the Method series are deviating from the actual printing time.
It’s not possible yet, to use Method series printers with Digital Factory. We hope to resolve this for the next release.
New Engine Plugin:
Not related to this release but nice to mention is that there is a new plugin has been created by the Cura team that makes use of the improved engine plugin capabilities introduced in Cura 5.5 (as mentioned #15629). The plugin is called CuraEngine Tiled Infill Generation and it allows users to select from an expanded list of infill patterns, as well as allowing users to add their own infill pattern by uploading a *.wtk file.
This plugin is just a taste of what is now possible when creating Cura plugins. We look forward to seeing what the Cura community creates next!

New in Ultimaker Cura 5.5.0 (Oct 25, 2023)

New features and improvements:
Engine Plugins:
Introduced infrastructure for Engine Plugins; Plugin developers can now hook into and change the actual slice process using a programming language in which they feel comfortable: C++, Python, C#/.NET, Dart, Go, Java, Kotlin, Node, Objective-C, PHP, Ruby
In this initial version, plugins can hook into the following engine slots:
Modify generated gcode, postprocessing it per layer
Generate Infill patterns
Modify extrusion paths
Listen to a broadcast of all Settings
Cura plugins can now easily add new Settings and extend existing dropdown Settings. Users are now warned if a previously saved project file depends on a plugin and that plugin isn't installed in the Cura instance that tries to load it.
To showcase this new infrastructure we introduced a Gradual Flow Engine plugin; This plugin prevents sudden drastic changes in flow transitions. You can find it under your bundled plugins and the new gradual flow settings can be found in the material category when all settings are visible
Do you want to participate in the discussion about the potential and possibilities? You can join the discussion on GitHub here.
Introduced the following new settings:
Gradual Flow Enabled, Gradual Flow Max Acceleration, Initial Layer Max Flow Acceleration, Gradual Flow discretization step size, are to finetune the Gradual Flow plug-in.
Top Surface Outer Wall Flow, Top Surface Inner Wall Flow, Top Surface Outer Wall Speed, Top Surface Inner Wall Speed, Top Surface Outer Wall Acceleration, Top Surface Inner Wall Acceleration, Top Surface Outer Wall Jerk, and Top Surface Inner Wall Jerk settings can be used to tune the top surface of your models.
Small Top/Bottom Width reduces jerky motions in small top/bottom surfaces, with Small Top/Bottom On Surface you can exclude the setting on the surface
Group Outer Walls will bundle types of walls in the same layer reducing travels, thanks to the contribution by @Arcari55
Enable Fluid Motion, Fluid Motion Shift Distance, Fluid Motions Small Distance, and Fluid Motion Angle are settings for printers with smooth motion planners like Klipper. It's hard to show the changes in preview, but we encourage you to check it out.
Updates in the available supported OSses:
Introduced Max OSX builds for ARM64 (M1 support), next to our existing X64 builds. With major contributions from @TheSin
Introduced a single Linux build removing the need to have a different modern and regular Linux build.
Setting improvements for Ultimaker Printers:
UltiMaker printers with UltiMaker Materials have faster-predicted printing times as a result of a number of changed printing speeds
UltiMaker configurations with limited intents in the past like AA 0.8 cores, now have more intents available
Updated printing temperatures for UltiMaker printers to be more uniform
Updated Support Interface Settings for UltiMaker printers
Introduced a support material tag, so support is automatically printed with support material
Default has been updated to Balanced to reflect the perfect harmony between these visual, engineering, and draft profiles.
Quality of Life Improvements:
Use Tab to navigate between settings in the Per Model Settings window, solves #10967
Introduced Ctrl-C and Ctrl-V next to the current multiply behavior, solves #8859
Arrange your models in a grid with the same orientation with Grid Placement

Searching for materials and plugins in the Cura Marketplace has been improved
"This Setting Is Hidden Because" icons were missing in the settings visibility for Windows and Mac
Only one file could be loaded and you could not load multiple files if they were mixed STLs and Project Files, solves #15879
It seemed like models could be multiplied more than 99 times, there is now a limit, solves #14105
It's now more clear if Cura is syncing materials over the cloud
It's not possible anymore to send a printjob to a turned off cloud connected UltiMaker printer
More Features:
You can now sponsor the Cura team from the Application Switcher, and Help menu
Infill behavior close to the skin to prevent jerky motions and visible overextrusion
The About Dialog includes more build information for Cura developers
Introduced more hardware info like system, release, version, processor, and CPU cores to the logging to improve troubleshooting.

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.

New in Ultimaker Cura 5.1.1 (Sep 13, 2022)

New in Ultimaker Cura 5.1.0 (Jul 19, 2022)

Improved toolpath simplification algorithm:
The algorithm that reduces the resolution of the print has been rewritten, providing a more constant resolution to allow for greater precision without causing buffer underruns.
Added option to alternate wall direction:
A new setting causes the direction of printing walls to alternate between layers and adjacent walls, which reduces warping in the print.
Adjusted combing boundaries to reduce scarring:
Travel moves through the inside of the models are adjusted so that they should keep more distance from the model where possible, yet allowing travels through narrow parts without retractions.
Reduced acceleration and jerk commands for travel moves:
We added the option to disable acceleration and jerk commands for travel moves. If disabled, they will take on the acceleration of the printed part of its destination. This greatly reduces file size and buffer underruns.
Project files know which packages they require:
Newly created project files will now store which packages they require from the Ultimaker Marketplace. If a project needs a material from there, the user will be prompted to download it.
Other new features and improvements:
The interface to select the printing profile in Recommended Mode has been redesigned.
Implemented multi-threaded slicing for MacOS, to bring it in line with other operating systems, contributed by @Piezoid.
Cura now links toolpaths to project files in the Digital Factory.
Improved performance of loading STL files on Linux.
Packages from the Marketplace can now contain intent profiles.
The application now makes heavy use of Conan to make it easier and faster to build releases of Cura.
Start and end g-code can now refer to the currently active profile with replacement keys.

New in Ultimaker Cura 5.1.0 Beta (Jul 11, 2022)

Improved toolpath simplification algorithm:
The algorithm that reduces the resolution of the print has been rewritten, providing a more constant resolution to allow for greater precision without causing buffer underruns.
Adjusted combing boundaries to reduce scarring:
Travel moves through the inside of the models are adjusted so that they should keep more distance from the model where possible, yet allowing travels through narrow parts without retractions.
Reduced acceleration and jerk commands for travel moves:
We added the option to disable acceleration and jerk commands for travel moves. If disabled, they will take on the acceleration of the printed part of its destination. This greatly reduces file size and buffer underruns.
Project files know which packages they require:
Newly created project files will now store which packages they require from the Ultimaker Marketplace. If a project needs a material from there, the user will be prompted to download it.
Other new features and improvements:
Cura now links toolpaths to project files in the Digital Factory.
Improved performance of loading STL files on Linux.
Packages from the Marketplace can now contain intent profiles.
The application now makes heavy use of Conan to make it easier and faster to build releases of Cura.
Start and end g-code can now refer to the currently active profile with replacement keys.

New in Ultimaker Cura 5.0.0 (Jul 11, 2022)

New slicing engine:
Following special beta releases to test the Arachne engine, we are pleased to announce our new slicing engine is here in Ultimaker Cura! This all-new engine uses variable line widths when preparing files for printing, meaning you can now print thin and intricate parts more accurately and with greater strength.
Renewed the Ultimaker Cura Marketplace:
We have streamlined the workflow for accessing the Ultimaker Marketplace inside of Ultimaker Cura. The UI has been improved and it’s now easier and faster to find and install plugins and material profiles.
Improved print profiles for Ultimaker printers:
The new slicing engine in Ultimaker Cura 5.0 has helped us to improve our print profiles. This means that users of Ultimaker printers can achieve speed increases of up to 20%.
