Ultimaker Cura 4.5 February 26, 2020 UsabilityUltimaker Marketplace sync. Plugins and print profiles downloaded from the Ultimaker Marketplace will now become associated with your Ultimaker account when logged in.
If changes are detected in your installation after logging in, an option to sync a list of available packages will become available. You can also add packages to your installation using the web-based.Layer preview number. The layer slider number in preview mode is now at the top, instead of on the left, for a neater fit next to the settings panel.Project name in window title. In the same way your browser shows the page title next to the name of the application, Cura now shows the name of the loaded file in the title bar. Slicing enhancementsFuzzy skin outside only.
When enabled, this option prevents fuzzy skin inside holes. This way you can still fit your prints around other things – useful for printing grips or similar applications.Brim distance.
This new setting contributed by allows you to define a gap between the brim and the model for easier brim removal and reduced chance of leaving a mark on the finished piece.' Skin Edge Support' settings. It’s now possible to add an extra line inside your infill that supports the edge of the skin better. Two new settings contributed by control this feature: ‘Skin Edge Support Thickness’ and ‘Skin Edge Support Layers’. Find these under ‘Infill settings’.Bridge over low density infill. Has contributed a new setting that determines if the infill density in a location is lower than the specified infill density, skin and walls above it should be treated as bridging.Shared heater.
A new ‘Shared heater’ checkbox has been added to the machine settings page to support printers that have one nozzle and one heater, but multiple feeders. When enabled, heating and pre-heating procedures act differently so that the nozzle doesn’t cool down for the stand-by temperature or the initial/final printing temperatures. Contributed by.Material mixing. A new post-processing script can be used to mix materials if you have a mixing nozzle.
Mix materials of different colors in order to print in a different color than either of your currently loaded materials. Contributed by.Infill mesh planning. Another contribution from optimizes the order in which infill meshes print their parts.
It now takes the previous location into account instead of always the starting location.Automatic extruder values. Automatic extruder values are now added for dual extrusion when slicing via the command line.Gamma correction for lithopanes. Loading an image file into Cura creates a heightmap that can be used to make lithopanes. Has altered the method of calculating this to apply gamma correction, so that the lightness of the pane is more truthful to the original lightness.Support for alpha channels in ImageReader. Added support for images with transparency, such as PNGs. When using an image with transparency, the contours of the transparent layer will be followed.
Performance improvementsSpeed up plugin loading. Has contributed a code optimization to load plugins faster on start. Mileage may vary, but Cura’s startup speed should see a marked improvement.Crash logging. We switched to a more robust provider for crash analytics, so we can develop a more stable product for you. We also added some extra datapoints to crash reports.Scene re-rendering. A new performance enhancement that limits re-rendering of the application interface from ‘constant’ to ‘only-when-necessary’.HTTP request handling. Previous versions used different ways of handling HTTP requests.
This version uses a unified method, for better performance.Jobnames less sensitive to being touched. A contribution from has fixed an issue where the jobname in the bottom-left of the scene is no longer made static by clicking on it.
If you load a model and change to another printer, the prefix is now correctly updated.Property checks on instance containers. A new speed optimization for reading setting values from profiles. New printer definitionsNative support has been added for the following third-party printers. Find them in the ‘Add printer’ list.BeamUp S. Contributed by.Anet3D.

After a lot of sleuthing, we managed to fix a major bug for this release. The application was getting stuck on trying to load 'qgif.dll', which is required to load the PNG file for the splash screen. In other cases, it was caused by trying to load a DLL file from the Intel graphics driver for OpenGL.
Thanks to the community for the help and feedback to solve this one. Send logs!Round interpolated z values. When spiralizing, the interpolated z values are rounded to the nearest micron.
Contributed by.S-line build plate temp limit. Values over 125C will turn the setting input box orange for safety reasons. It’s still possible to print above these temperatures, though.Apple keyboard delete button. Fixed an issue where pressing the delete button on an Apple keyboard wouldn’t delete things.Added “all” setting visibility. Fixed an issue where selecting ‘all settings’ visibility in custom mode would override a custom selection of settings when switching back.Min x/y distance on sloped walls. Contribution from that uses minimum x/y distance when the layer below protrudes beyond current layer (i.e. Sloped walls).Large polygon ordering.
Another contribution from. This one speeds up the ordering of large numbers of polygons when using the combed travel distances.Surface mode: Don't combine overlapping. Fixed an issue where overlapping volumes interfered with each other when in surface mode. Contributed by.Time lapse post processing script.
Fixed a wrong extrusion move between the last x/y position and the ‘park head to take a photo’ position.Window size. Fixed an issue where window sizes weren’t saved when closing Ultimaker Cura. Contributed by.Prime tower duplicate brim. Fixed an issue where a duplicate brim was created when adhesion and a prime tower was enabled at the same time.
Contributed by.Different printer losing settings. Previous versions would lose modified settings when switching to a print group with printers of different types, e.g. Adding an Ultimaker 3, modifying the infill settings from the default profile, and then switching to an Ultimaker S5 would change infill settings back to the default profile value.
This version has fixed it.One-at-a-time slice overlapping models. Fixed an issue where one-at-a-time mode was marking models as unprintable even though they were. This occurred a lot with Creality printers, due to print head definition issues.Huge extrusions after bridging. Fixed an issue where there was a huge extrusion move after bridge wall lines.Minimum support area eating into parts. Setting ‘Minimum Support Interface Area’ or minimum ‘Support area’ to a non-zero value larger than the area of a model’s layer would cause support material to eat into features of the model. This has been fixed by.CXFreeze needs LDLIBRARYPATH. An issue caused by different Qt versions shipped with older versions of Cura would take a wrong instance which resulted in broken libraries.
This has been fixed by.Retraction Min Travel broken. We recently discovered this was broken since version 4.0. Luckily it was fixed by.Mirror + Lay Flat behaves the other way.
Fixed some broken behavior with mirror + lay flat settings when used together.Cura splash screen loading indicator doesn’t always spin. During some load phases, the spinner stops spinning, which could give the impression of a crash. This has been fixed.UI elements get obscured on small screens. In preview mode, the horizontal layer progress bar could be obscured by the print action panel on smaller screens. The frontend behavior has been modified to not do this.Brim extruder does not get used by all models.
Fixed an issue where the specified extruder for brims would not extrude for every brim when working with multiple models in print-one-at-a-time mode.Intent UI in dark theme. Fixed style inconsistencies when using dark mode.Pause at height pauses too late. Fixed an issue where the ‘Pause at height’ post processing script would ignore specified values.Material volume between wipes. Fixed an issue where this setting would ignore specified values.Start/End G-code comments.
Fixed an issue where comments were stripped out of G-code in start/end G-code fields.Manage materials for some printers not updating. Fixed an issue where changes did not show up when creating, deleting, renaming, or duplicating print profiles for some printers.Upgrade Script for machine duplication issue. Added a script to clean up hidden printers that were slowing down Cura's performance in the background.ZeroConf - slow Cura. The listening service for network printers could sometimes cause reduced performance, even when networked printers weren’t used. This has been fixed.Merge Tree Support Wall Line Count into Support Wall Line Count. The ‘Support wall line count’ setting now has influence over tree support wall lines. Fixes a bug where custom support models weren’t being printed.Crash loading project files.
Fixed random crashes when loading project files for custom FFF printers.Duplicated PLA different properties. Fixed an issue where a duplicated profile would assign values in the wrong fields.Fix concentric skin. Fixed an issue where large areas of concentric skin would accumulate small approximation differences and not be roughly concentric any more towards the center. Contributed by.Found a bug in this release? Spotted a mistake in these release notes? Beta release of the upcoming 4.5 version. We usually release the final release +/- 2 weeks after the beta.

Intent profiles.What’s the intent of your print? A rapid prototype?
A visual prototype? An end-use part with specific holes sizes?
Intent profiles accelerate the CAD-CAM workflow by preconfiguring all the right settings in Ultimaker Cura for each of these use cases. Simply select a profile that matches the intent of your design, slice, and you’re ready to print immediately, without the need to adjust the typical settings. For now, there are three Intent profiles:. ‘Draft’Intended for initial prototypes and concept validation, and will print your design in the shortest time possible. ‘Engineering’Intended for high-dimensional accuracy, to print functional prototypes and mechanical end-use parts.
‘Visual’Intended for visual prototypes and prints that need excellent aesthetic quality.For now, these profiles work for the Ultimaker S5 and Ultimaker S3 with Ultimaker PLA, Tough PLA, and ABS materials, and include PVA and Breakaway combinations. More profiles will follow over time.Per-model settings.Per-model settings are a set of very powerful features for users who need to tweak specific settings in specific parts of the model. In previous releases these were buried in the interface somewhat, so this release has made them more discoverable with clear icons in the toolbar, so everyone can discover them. The per-model settings can now be accessed both when working from the recommended and the custom print settings mode.Specify network printer.When connected to an Ultimaker Connect group of multiple printers, Ultimaker Cura once again shows a pop-up to select a designated printer for your printjob. This functionality had been disabled in the last version to ensure reliability when printing remotely.Performance improvements.Various tweaks under the hood for a snappier, more responsive interface. This improvement is most noticeable when switching extruders, print profiles, hovering over tooltips and when scrolling through the print settings list.SDK version increment.The changes made in version 4.4 (mainly for intents but also other things) are so thorough that we needed to do a major increment of the SDK version.
Contributors – please update your packages!.Pause at height message.A setting has been added to the pause at height script that displays a custom message on screen. This can be used to give instructions to operators to perform an action during the pause, e.g. ‘Place 626 bearings in slots now’.Restore window preference.has contributed a new preference around restoring the previous window position/size to the last used position/size on start up. This would be a workaround for those setups where starting Ultimaker Cura on a secondary screen will prevent it from working.Group Linux instances.has contributed a fix so that multiple instances of Ultimaker Cura get grouped in one application group in Gnome (the Linux front-end).
It adds a bit of metadata to the.desktop file so that the windows can be grouped.Known bugsCura not starting on Windows 10. Some users started reporting that Ultimaker Cura 4.3 and higher did not start properly, fur unknown reasons. We have implemented some code to get a better understanding of the issue, but we have not been able to fix it just yet.As a quick fix: Go to the install path, by default “C:Program FilesUltimaker Cura 4.4”. Right click Cura.exe and select ‘properties’.
Click the ‘compatibility’ tab and select “Run This Program in Compatibility Mode For: Windows 8”. If this does not fix your issue, please contact your service provider.Minor improvements.

Due to a major SDK change (7.0.0), a pre-release is made available to allow plugin developers more time to update their plugins.We have added the following:. The ContainerTree class provides easy access to which profiles are available for each configuration in Cura.
QualityManagementModel is expanded to contain functions for duplicating, deleting, etc. Of custom profiles. MaterialManagementModel is expanded to contain functions for duplicating, deleting, etc.
Of materials. Setting version is incremented to 10. Per-extruder container stacks now contain an additional entry: The 'intent' profile, meant to indicate how the user intends to use the print: For strength, accuracy, just visual, etc. IntentCategoryModel provides a list of the available intent categories. IntentModel provides a list of the available intent profiles per intent category. A new decorator marks certain things as 'API', to mark certain things as considered completely stable for plug-ins to use. These markers have not yet been added to all things that we consider stable to use, though.
Metadata can now be set per PluginObject, allowing multiple of the same type of PluginObjects to be defined in one plug-in. PluginObjects have a getName function to disambiguate them.We have removed the following:. MaterialManager.
Use ContainerTree or MaterialManagementModel instead. QualityManager.
Use ContainerTree or QualityManagementModel instead. VariantManager. Use ContainerTree instead.
4.3.0 Ultimaker S3This release includes a new profile for our latest S-line of 3D printers: the Ultimaker S3. Eagle-eyed beta testers may have noticed this extra printer profile in the beta release, too. Well done to those who spotted it. Learn more about the Ultimaker S3 by reading the blog on Ultimaker.com.
Even more 3D file formatsThis version is compatible with even more 3D file formats out-of-the-box, so you can integrate CAD software, 3D scanning software, and 3D modeling software into your workflow with ease. Natively open Collada, GLTF, OpenCTM, and PLY formats, to name a few. And don’t forget, downloading plugins from the Ultimaker Marketplace brings in support for many more. Align faces to the build plateOrienting your models with the rotation tool or the lay flat tool can be a hassle with complex geometries. This new time-saving feature lets you select a face of your model to rest on the build plate, so you can get the orientation you need quickly and easily. Please note this is disabled in compatibility mode (and if your machine is running OpenGL 3.2 or lower).
Support infill/interface line directionsImprove reliability with more precise control over certain aspects of your print. Choose the angle that support-infill and interfaces print at, thanks to a contribution from vgribinchuck. Input a set of angles you want lines generated at, and these will be placed sequentially throughout your 3D print. Randomize infill startRandomize which infill line is printed first. This distributes strength across the model, preventing one segment becoming the weakest link, at the cost of an additional travel move. Print small features slowerSmartavionics has contributed a setting which recognizes small perimeters and reduces print speed in order to boost the reliability and accuracy of small printed features. This is especially useful for small perimeters such as printed holes, as they tend to get ripped away from the build plate easily due to their low contact area.
Easy selector for Z seam positionsZ seams are now easier to position on your model, thanks to a contribution by trouch. A drop down selection box has been added to custom mode, giving you a list of presets to place the z seam on your model. Colorblind assist themeNubnubbud has added a new theme for colorblind users which makes more distinction between colors, such as the yellow/green line colors in the layer view. DisplayFilenameAndLayerOnLCD scriptSome improvements for this post processing script from the community. N95JPL has contributed updates to offer a wider range of optional information.
Adecastilho has contributed updates so that the layer count is displayed before the filename to prevent the layer number getting truncated in the event of long filename, as well as an option to start layer count at either 0 or 1. The ':' in the display string has also been removed as it is a GCODE command that splits the line into two different commands. Peripheral information for output devicesArchitectural changes in Ultimaker Cura to allow display information about peripherals in the printer output device, so that I can use it to later on show that information in the Monitor stage plugin. Quality changes on importUsers can now import profiles that have been created on a different machine other than the active one. Remove prime after coastingReduce the visibility of the z seam when printing with coasting by preventing nozzle priming. Map Material Station slot dataThe available configurations drop down will display information about a Ultimaker S5 Material Station if connected.
Read more about the Ultimaker S5 Material Station on Manage Printer linkAdded a “Manage Printer” link in the monitor tab which takes you to Ultimaker Connect. Improvement in code qualityImproved code quality resulting in improved stability. Bug fixes. Uninstall in silent mode.
Fixed an issue where a dialog displays when uninstalling in silent mode. Build Interface if Support is Present. In some cases, support could be pushed away by large support XY distance, but interfaces could be left on overhangs which leads to situation when interface is generated without support.
This has been fixed. Install in silent mode. The bundled Arduino driver is signed by a certificate that's not trusted on Windows by default, so there was no way to suppress the prompt or to have the installer skip driver installation. This has been fixed. 3MF project printer connection not included. When loading a project file that was saved while a network connection was active, the network connection is not re-established. This has been fixed.
Thin Walls broken. Fixed an error with thin walls being broken. Tray icon remaining. Fixed a bug where the tray icon would remain after closing the application. Marketplace text. Fixed an issue where Marketplace text is blurry on some screens. Unsupported profile imports.
Fixed an issue where exported profiles could not be reimported. Loading file message. Added visual feedback when loading files such as STLs. Loading GCODE on disabled extruders. Fixed an issue where GCODE imported using multi-extrusion fails to load if an extruder is disabled. Support brim with concentric support pattern. Fixed an issue where support would be in mid-air.
Reduced cloud logging. Logging has been reduced for cloud connections on unstable connections. Application menu extruder menu. Fixed an issue where changing the extruder via the application menu didn’t work. Tool handles move when rotating. Fixed an issue where rotate tool handles would change location when rotating. F5 reload.
Fixed an issue where F5 doesn't reload GCODE. Application not starting before the splash screen. Fixed an issue where the application wouldn’t start before the splash window. Qt 5.13 crashes. Fixed an issue where the ShaderEffect crashes using Qt 5.13. Can’t select other materials in print setting tab.
Fixed an issue where other materials couldn’t be selected using the print settings tab. Drop down to buildplate after resize. Models don’t drop down to the build plate if they are scaled down from ‘too large to fit’. Unsupported quality profiles. Fixed unsupported quality profiles appearing for 0.25 + 0.8 print core combinations.
'Arrange all models' for groups. Fixed an issue where arrange all models hangs for grouped models. Update Checker not working. Fixed this so that updates are visible if using a legacy version.
Missing support brim. Fixed an issue where support brim was missing if platform adhesion set to ‘None’. Multiply non-normal mesh doesn't work. Fixed instances where processes stopped and messages would hang. Settings not updating in GUI with inheritance. Fixed settings not updating GUI with inheritance.
Prevent 'generic'-part in name of specific materials. Introduced checks for ‘generic’ material types to help material categorization. Hide temperature settings. The 'Default Print Temperature' setting is currently editable, but editing this setting can cause problems with temperatures later especially when you have it in your custom profile.
We decided to hide this setting so users can no longer edit it in the later releases to avoid confusion. The 'Default Build Plate Temperature' has also been hidden because it causes a similar issue. Add machineheatedbuildvolume. Introduced a new machineheatedbuildvolume machine-setting, which is set it to false by default, and only set it to true for the Ultimaker S5. Users can alter their own definition if they do have a heated build volume.
Z-hops on first layer. First move other start GCODE not z-hopped. Contributed by sailorgreg. Preserve extruder-only moves in post stretch script. Contributed by sgtnoodle. “Print via Cloud” is no longer possible without an Internet connection. Monitor tab no longer sometimes shows incorrect printer name or type.
Long print job names are no longer overlapping other text in the monitor tab. “Connected to Cloud” pop-up now only displays when the currently selected printer is connected to Ultimaker cloud. Monitor tab is no longer greyed out when idle.Third-party printer definitionsNew machine definitions added for:.
IMADE3D Jellybox. Contributed by filipgoc for IMADE3D Jellybox printers, which adds JellyBOX 2 printer and revises settings of JellyBOX Original. Vertex Nano. Contributed by velbn. Felix Pro 2. Contributed by pnks.
JGAurora A35. Contributed by pinchies.
eMotionTech Strateo3D. Contributed by KOUBeMT. NWA3D A31. Contributed by DragonJe. 4.2.1 Bug fixes. Fixed a bug in the error checker where the slicer prevents a slice even when all the settings have the correct value, or it doesn't indicate which settings have an incorrect value. Fixed 'Z Hop Speed' error in the new Creality profiles that prevents the slice when the 'Z hop when retracting' setting is enabled.
This happened as well when enabling support since 'Z hop when retracting' is enabled in this case. Fixed importing old profiles for Creality CR10s. After the inclusion of the CreawsomeMod profiles, the version upgrade didn't take Creality CR10s into account.4.2.0 Orthographic viewWhen preparing prints, professional users wanted more control over the 3D view type, so this version introduces an orthographic view, which is the same view type used by most professional CAD software packages.
Find the orthographic view in View Camera view Orthographic, and compare the dimensions of your model to your CAD design with ease. Object listEasily identify corresponding filenames and models with this new popup list. Click a model in the viewport and its filename will highlight, or click a filename in the list and the corresponding model will highlight. The open or hidden state of the list will persist between sessions. How convenient. Print previewsSome improvements have been made to print previews displayed in the monitor tab, Ultimaker Connect, or the Ultimaker S5 interface.
In some instances, previews were clipped at the bottom or side, and sometimes models outside of the build plate area were visible. This is all fixed now.
AMF file compatibilityUltimaker Cura now supports AMF (Additive manufacturing file format) files out-of-the-box, thanks to an AMF file reader contributed by fieldOfView. Slice button delay.After clicking ‘Slice’, a lack of response could lead to frustrated buttonclicking. This version changes the button text to read ‘Processing’ during any pre-slicing delay. Layer view line typeThe line type color scheme in the layer view has been tweaked with new colors for infill and support interfaces so that they can be distinguished better. Nozzle switch prime distanceCertain materials “ooze” more than others during retraction and long moves.
Vgribinchuk has contributed a new setting that lets you finetune the restart distance, so that the full extrusion width is achieved when resuming a print. Smart Z seamA new option to increase the aesthetic quality of your prints has been added to custom mode, under Z seam settings.
Smart Z seam works by analyzing your model’s geometry and automatically choosing when to hide or expose the seam, so that visible seams on outer walls are kept to a minimum. Separate Z axis movementsZ axis movement handling has been improved to reduce the chance of print head collisions with prints. Flow per featureYou can now adjust material flow for specific features of your print, such as walls, infill, support, prime towers, and adhesion. This allows line spacing to be controlled separately from flow settings. Merge infill linesWe did some finetuning of the CuraEngine to improve print quality by filling thin infill areas more precisely and efficiently, and reducing movements that caused excessive gantry vibration. Z hop speedThe Z hop speed for printers with no specific speed value would default to ‘00’ (light speed!) The new Z hop speed setting ensures that all Z hops are performed at a more sensible speed, which you can control.
Support tower diameterThe ‘Minimum diameter’ setting for support towers has been renamed to ‘Maximum Tower-Supported Diameter’, which is more accurate and more specific because it mentions towers. Square prime towersCircular prime towers are now the default option. Square prime towers have been eradicated forever.
Third-party printer orderThe ‘add printer’ menu now includes third-party printers that are ordered by manufacturer, so that specific machines can be found easily. Printer definitions. New machine definitions added for:. Anet A6.

FL Sun QQ. Contributed by curso007. GeeTech A30. Contributed by curso007.Creawsome modThis version has pulled the Creawsome mod, made by trouch , which adds a lot of print profiles for Creality printers. It includes definitions for Creality CR10 Mini, CR10s, CR10s Pro, CR20, CR20 Pro, Ender 2, Ender 4 and Ender 5, and updates the definitions for CR10, CR10s4, CR10s5 and Ender3. The CRX is untouched.
Pull requests are now submitted that merge the mod into mainline Cura. Bug fixes.
Noto Sans. Noto Sans was introduced as the default font in Ultimaker Cura some versions ago, but until now it wouldn’t render properly in the application unless already installed on your computer. This release forces the application to render Noto Sans even when it’s not installed as a font on your computer.
Fun fact: Ultimaker recently rebranded, and we made Noto Sans our corporate font as well. Reslice with per-model settings. When slicing a model with per-model settings, a change of one of the per model settings would not trigger a reslice.
This has been fixed. Serial port interruptions. This version adds a way to stop serial connections if you add command line parameters. Print one-at-a-time blob. In print-one-at-a-time mode, prime blobs could cause obstructions and cause prints to fail. This has been fixed. Prime tower brim overlap fix.
Fixed an issue where models on the build plate could overlap with brims of other models. Wrong printer name. Fixed an issue where Ultimaker 3D printers that are synchronized over the network would display ‘Extruder 1’ in place of the printer’s hostname. Unnecessary travel at print start. Fixed an issue where printing without a prime blob would cause the print head to make a 10 mm travel move for no reason. Stair step height.
This version fixes support stair step height, which influences the adhesion between the model and support printed on top (supports everywhere). For now, this bug has had no influence on PVA supported prints.
