UltiMaker Cura 5.14.0-alpha.0

New features and improvements:

• Introduced support-painting: paint on the model to indicate where support should and shouldn't be placed

Take complete control over your supports with our new Support Painting feature. You can now customize exactly where supports are placed simply by brushing them directly onto your 3D model. Whether you want to fine-tune auto-generated structures or paint an entirely custom support pattern from scratch, this intuitive tool gives you absolute authority over your print's stability. By targeting only the necessary areas, you can significantly reduce print times, save filament, and ensure cleaner surface finishes upon support removal.

• Experimental support for Cura on Windows ARM platforms

With this release, we are excited to introduce an experimental Cura installer built specifically for Windows on ARM architecture. This preview allows users on ARM-powered devices (such as those running Qualcomm Snapdragon processors) to experience the native Cura workflow and performance. Please note that as an experimental release, you may encounter occasional bugs or performance inconsistencies. We highly encourage our community to test it out and share feedback to help us refine the experience.

• Custom GCode parts are now processed in the engine, to ensure that all the variables have the most accurate value
• End-of-print GCode variables are now processed in the engine, to ensure that more accurate values are inserted, contributed by Erwan MATHIEU (@wawanbreton)
• Dialogs that were previously created at application boot are now created only when necessary, which saves some boot time and memory
• Discard top and bottom surfaces when their settings are identical to skin settings, which avoids printing them separately
• Discard very thin infill areas that are printed within skin and disrupts the flow
• Improve positioning of models when loading multiple models from a non-project 3MF file
• Improved the OpenGL shaders compatibility, contributed by HellAholic

New Settings:

• Introduced Top/Bottom/Skin Merge Distance, which allows merging those areas together wen they are too small to be printed correctly
• Introduced Minimum Infill Line Length, which allows removing unnecessary lines of infill added in small areas

Bug fixes:

• Fixed the most common sources of slicing crashes (those that would have to be worked around by moving the model on the build plate)
• Removed an unnecessary and long travel move added when printing supported floating models
• Fixed an issue where top and bottom surfaces could be generated, although they were disabled
• Fixed the print temperature command of the initial layer when using the 'zigzag' pattern, contributed by HellAholic
• Fixed an issue where the project window could be displayed at an unexpected position

Printer definitions, profiles and materials

• Removed hardcoded T0 in start gcode for anycubic ACE PRO enabled K3
• Fixed multiple bugs in Elegoo Neptune 3 Pro: acceleration, retraction_combing, end gcode

UltiMaker Cura 5.13.0

New features and improvements:

• Added the new UltiMaker Factor 4+ printer, including profiles
• Added option to specify file association during the installation of Cura for windows, contributed by HellAholic

New Settings:

• Introduced Infill Start/End Preference settings that give control over the starting location of infill
• Added Support Infill option "Lightning", and in addition the following supporting settings: Support Lightning Angle, Support Lightning Overhang Angle, Support Lightning Prune Angle, and Support Lightning Straightening Angle, which together allow you to add and control lightning infill generated for support structures
• The Support Infill Line Multiplier has been introduced to increase the quantity of infill lines. When an even number of lines is specified through this setting and paired with lightning support, it produces a single extrusion line for each island
• Introduced Minimum Hole Area in Brim Support, which filters out small holes in the support brim, resulting in a more consistent brim
• Added Temperature Delta Top Surface, which allows you to print top surfaces at a different temperature
• Added more options to Retract Before Outer Wall to give more control over retraction behavior when traveling to the outer wall
• Added Initial Layer Wall Ordering which gives control over the order in which the walls are printed for the initial layer, contributed by HellAholic

Bug fixes:

• Support blockers now function correctly even when assigned to a disabled extruder; they no longer cause slicing conflicts and continue to effectively block support
• Fixed an issue where thin support structures would be generated within tree support
• Fixed an issue where the tree support interface layer would be missing
• Randomized infill now also works for infill skin support
• Fixed an issue where Keep or Discard profile user preference would be ignored
• Overhanging wall speed was previously applied too aggressively, resulting in extremely slow printing in overhanging areas
• Travel speed was applied to layer switches, resulting in high-speed Z-travels
• Fixed an issue where certain 3MF files would incorrectly load with an invalid setting configuration
• Fixed an issue where certain setting combinations would skip parts of the skin and walls sections
• Resolved an issue where slicing would fail when both Raft build plate adhesion and Support Lightning Infill were enabled
• Fixed an issue where overhang speed would be applied inconsistently when both Split Infill and Overhang Speed settings were enabled
• Fixed an issue where the profile has changes notification would overlap with UI elements
• Fixed an issue where certain setting configurations would cause a large amount of small line segments to be generated for the prime tower
• Fixed an issue where clicking the "Sign in to Digital Factory" button twice would fail to log in

Printer definitions, profiles and materials:

• Updated high-speed S-Line profiles to improve tree support strength and improved seam behavior by ending infill close to the seam and traveling to the seam unretracted
• Improved material detection for Method line printers to automatically select support material for the raft interface
• Automatically disable Infill Skin Support if Gradual Infill Steps is enabled, since these are conflicting settings, contributed by HellAholic

UltiMaker Cura 5.12.1

Bug fixes:

• Fixed an issue where the export action for .makerbot file format would fail unexpectedly.

UltiMaker Cura 5.12.0

New features and improvements:

Bridging behavior over rectangular empty spaces and infill are now placed in a smarter way. The bridge lines are now anchored to layers below where possible. Bridge lines can now also be interlaced for improved quality.

Fewer mistakes, less wasted time. Settings for disabled extruders are now greyed out to prevent "ghost editing," where you might spend time fine-tuning the Printing Temperature or Retraction Distance for Extruder 2, only to realize later that the entire model was set to print with Extruder 1. Additionally, a warning appears in the Preview stage if your model is hidden because an extruder is unchecked.

• Updated combing behavior for thin parts so it doesn't ooze over the walls by updating the behavior for Inside Travel Avoid Distance
• Added a warning in the preview if the reason you are not seeing your model is that the extruder is unchecked
• Self-intersecting infills like Grid, Triangular, and Cubic are hidden for some printers in recommended mode because they introduce artifacts at high speeds. They are still available in Custom mode
• Added height of the layer in preview mode in mm in addition to the layer number, contributed by HellAholic
• Added a pop-up to help with using the Select Face mode when rotating a model, resolves #21359, contributed by HellAholic
• Improved the reliability and maintainability of the Cura UI and Post Processing plugin, contributed by HellAholic
• Added a new button under the Help dropdown to quickly open the log files, contributed by HellAholic
• Updated the Filament Change script of the Post Processing plugin to support multiline Gcode Before and Gcode After, contributed by Olivier B (@hobbe) and GregValiant (@GregValiant)
• Updated the Z-Hop on Travel Post Processing script to include an option for Support Interface Only, contributed by GregValiant (@GregValiant)
• Updated the Post Processing plugin with a bigger text area in the UI to allow for easier editing of multiple lines of Gcode, contributed by HellAholic
• Updated the Advanced Cooling Fan Control Post Processing plugin to add an Enable and Fan Jump Start setting, contributed by GregValiant (@GregValiant)
• Updated the Display Info on LCD Post Processing plugin to reflect Filament Cost and allow for the adjustment of the Cura estimated time, contributed by GregValiant (@GregValiant)
• Updated the Purge Lines and Unload Post Processing plugin so the CUSTOM addition in the Gcode doesn't trigger an error, contributed by GregValiant (@GregValiant)

New Settings:

New Honeycomb and Octagon infill types ensure the toolpath never crosses its own path on the same layer, reducing the chance of the nozzle hitting the infill during printing. Infill Start/End Move settings move the infill starts away from the wall to prevent surface blobs from a nozzle traveling to start a new infill line.

• Introduced Infill Start/End Move Inwards Length settings that add an extra line at the beginning and the end of your infill to prime the infill and prevent blobs on the outside wall
• Introduced Infill Skin Support to consolidate and replace Extra Infill Lines to Support Skin, Skin Edge Support Layer, and Bridging Over Infill Settings.
• Introduced a Middle option to the Z Seam Positions, contributed by GregValiant (@GregValiant) HellAholic

• Fixed an issue where combing would add a lot of unnecessary travel due to a very small slit in layer outline, resolves #21381
• Updated the behavior of the preview tab when dragging and dropping in a Gcode file, resolves #21110
• Fixed an issue where enabling Z hop when retracted would apply the Z hop twice and move the nozzle to X0 Y0 at start of the print, resolves #21132
• Polished the appearance and behavior of combobox controls in the Preferences dialog, making them more consistent and easier to use.
• Fixed an issue that would cause a crash if the model was reloaded inside the paint mode, resolves #21304

• Fixed a case where infill extrusion moves could skip the intended inward move, improving infill start placement and reducing small artefacts at infill boundaries.
• Addressed a CuraEngine issue that caused slicing to crash when generating the inward infill move, making slicing more robust for tricky geometries.
• Removed the nozzle move to X0 Y0 when Z Hop When Retracted was enabled, resolves #21132
• Fixed a bug where the Infill Skin Support would move through the Extra Infill Walls

🖼️Painting + BambuLabs Build🖼️ (5.11 Alpha)

⚠️Warnings & Disclaimers⚠️

• Alpha's and 'nightlies' are experimental builds -- please use this release in an exploratory fashion only, please do not rely on it for important tasks like production.
• Features introduced in this build are (often) unfinished, may be drastically altered for Beta (and subsequent Final) release(s), or even outright removed.
• This build will also not receive any official support -- it is purely to (showcase and) facilitate discussion of new features within the Cura-community.
• This effort is our own and should not be seen as a formal partnership with any 3rd party. We are aware that there are clear differences between us and BambuLabs. However, we both share a fundamental commitment to empowering the 3D printing community. Our focus is on supporting creators and pushing the boundaries of what is possible.

A nightly build with Painting 🎨 and Bambu 🎋

Once again, two sizeable new features that we'd like to have your feedback on have (nearly) arrived to Cura!

• We've introduced a Painting Tool into Cura -- for now, this can be used to paint allowed or disallowed areas for seam, or to paint on materials.
• Bambu-printers work a little different than most things out there in the 3D printing ecosystem (at least from a slicer perspective) -- so we had to pull out some tricks to get them working together properly with Cura.

Also, we've introduced a feature just for builds like this; where you can select if you'd like to 'start clean' or use the current configuration folder -- this helps not contaminate your main config should the alpha still have some issues. -- Also the banner-colour on the top is different from our usual deep blue, to let you know this isn't a normal release (or beta).

Painting 🎨

Painting, or various tasks that practically require paint-on functionality, have been a much requested feature for a good while. For now with the first introduction of paint-on in Cura, two of those features are coming along:

• Seam painting forces or disallows seams to be present on certain areas of the model.

• Material painting can be used to paint the use of different extruders onto, and into areas of the model -- we go a little deeper than our competition though -- the entire model is taken into account, not just the surface.

We are exploring other painting applications, like Paint On Support, but those are more effort than expected and might not show up in the upcoming release.

Known issues 🦟

• Occasionally, simpler(?) models can still generate a wrong UV-map -- a workaround is to export such an object to the .OBJ file-format, and then reload it -- the UV-mapping needed for painting should be correct. Try the above if painting doesn't seem to work properly at all.
• Painting (especially with multiple materials) may take extra slicing-time -- and progress isn't communicated to the front-end yet -- this means it may seem 'stuck' for a while after pressing Slice.
• Painting isn't fully optimized yet, which is why we've limited the brush-size for now. (In general, there are some issues with brush-size.)
• For painting, undo/redo works with Ctrl-L and Shift-Ctrl-L respectively -- since we don't know if it's wanted that the undo-stacks for (other) model-operations should be the same as the painting ones.
• There's some initial slowdown when applying the first brush-stroke(s).
• Internal testing shows that there might be a slowdown in Preview mode.

Bambu 🎋

Part of the reason Bambu-printers are so fast is that they have to do very little on-board operations w.r.t. gcode-postprocessing -- nearly everything is done by the slicer. Now, that slicer can be Cura.

Of course, with their multi-material capabilities, this synergizes with material-painting. (Just as with our own dual-extrusion.)

Known issues 🦟

• Reloading saved Bambu gcode-3MF's won't work for Previews (doesn't show layers).
• The display of layer progress on the LCD of a Bambu might not work properly (or at all).

Other Changes 🎁

All of this is built on top of our (current) in-progress work for the upcoming release, so you might see some other features pop-up, such as:

• Introduce capability to retract/unretract during travel.
• Control build-volume fan-speed (instead of just on/off).
• A fix for compatibility with the practices of certain anti-virus vendors (Windows -- newer versions of DLL's officially supplied by Microsoft wouldn't be 100% compatible to the version that at least one big anti-virus vendor forced Cura to run by DLL injection).

As well as a whole host of bug fixes, new printers and other improvements.

Why do we need you? 😎

• We have tested many builds of Cura, on many systems, but we know everyone has a different execution environment. The idea of this Alpha release is to make sure that it still works on all the platforms where it used to work before.
• We don't exactly know how everyone uses Cura. There may be some actions that you do, which will reveal a bug we didn't see in our tests.
• There are tons of plugins. So we want to make sure that they keep working with the new version.

What do you need to do? 💪

Well, not much, just download this version, use it as you would usually do, and send a brief feedback on the discussion: describe your environment, and tell us if everything went fine, or if you encountered some crashes or strange behaviours!

UltiMaker Cura 5.10.2

UltiMaker S6 and S8 improvements:

• Introduced the CC+ 0.6 core to the UltiMaker S6 and S8. This core delivers better results for demanding applications and will be replacing the CC+ 0.4 core.
• Added new profiles for PC and CPE+ on UltiMaker S6 and S8
• Updated the default support type for the PETG material for UltiMaker S6 and S8

This release introduces print quality improvements for the UltiMaker S6 and S8 for carbon-filled printing. We intend to improve more non-engineering materials in a follow-up release.

UltiMaker Cura 5.10.1

The new UltiMaker S6 is here

Print with the new UltiMaker S6 in Cura from day 1. The UltiMaker S6 is the newest addition to the S series of UltiMaker printers that carries forward the award-winning legacy of the S5, now supercharged with innovations like the UltiMaker Cheetah for up to 4x productivity. Learn more about this printer here.

Other improvements:

• Introduced Visual Intent profiles for PLA and Tough PLA for the UltiMaker S8
• Introduced High-Speed Intents for ABSR for Method X and Method XL

Bug fixes:

• Updated UltiMaker S8 profiles to significantly improve the quality of PC, CPE, CPE+, PETG, support structures, and dual extrusion prints
• Support brims no longer listen to the Brim Distance setting, so the brims will always be attached to the support
• Fixed a bug affecting multi-extruder printers where the initial temperature was not set correctly at the start of a print if all features used an extruder other than T0
