UltiMaker Cura Changelog

What's 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
  • 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:

  • 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!

  • If you had UltiMaker 3D printers active and you upgraded from Cura 5.4 to 5.5 beta to 5.5.0, you might need to discard your 5.5 configuration folder to resolve a configuration warning

New in UltiMaker Cura 3.4.1 (Sep 4, 2018)

  • Extra skin wall count. Fixed an issue that would occasionally cause an unnecessary extra skin wall to be printed, which increased print time.
  • Support on top of inner brim. Fixed an issue in which supports were not generated on the initial layer, because the engine expected a brim to be in place.
  • Conical and tree support. Conical and tree supports are now always limited within the build plate volume.
  • Various startup crash fixes. Fixed various startup crashes, including: copying of the version folder, errors while deleting packages, storing the old files, and losing data on install.

New in UltiMaker Cura 3.1.0 (Dec 27, 2017)

  • New profiles:
  • Profile added for 0.25 mm print core. New print core profile added for 0.25 mm print core. This new print core has an extra fine nozzle width, which gives prints high definition and increased surface quality.
  • Profile added for Breakaway material. New material profile added for Breakaway material, a dry post processing support material, which can be used for models with flat surface area overhangs.
  • UI enhancements:
  • Faster profile switching speed. Duplicating and removing a profile could take Ultimaker Cura quite some time, it now happens instantly.
  • Faster printer selection. Removing a printer from the library is now instant. No more unresponsive screens.
  • Faster processing speed. A 5 - 10 % speed increase when calculating normals, loading models, and slicing.
  • Quick camera controls. New buttons have been added to the interface that can quickly reposition the camera view of the build plate.
  • Lock model on platform. The move tool has a new option to lock a selected model to the platform. Once locked, it can not be moved in X, Y and Z directions.
  • Layer view. The existing Layer view has been updated to include a virtual print head that simulates the printing strategy. This can be used to see the printing order of infill and walls, and if line ordering affects overhangs.
  • Feedrate visualization. Feedrate visualization has been added to the Layer view. Speeds have corresponding colors, ranging from red to blue. Fast speeds (up to 250 mm/s) are represented by red (e.g. print head travels). Slower speeds (20 mm/s) are shown in blue, (e.g. the first layer of a print). Using this gives the user an idea of the print speeds per model part, allowing for better control over prints and more informed fabrication.
  • Jogging. Jogging allows the printhead to be moved with on-screen controls. The Ultimaker 2+ and other RepRap printers can now be fully controlled from Ultimaker Cura when connected through USB. Each axis can be jogged in 0.1, 1, 10 and 100 mm increments.
  • Large model loading. Loading large/detailed models and slicing them on a high resolution could affect the performance of Ultimaker Cura in previous releases. A new feature has been added which unloads the layer view when switching to solid mode, speeding Ultimaker Cura back up without losing your G-code/layer view information.
  • Scripts folder. A scripts folder is now available in the Ultimaker Cura configuration folder. This folder can be loaded with post processing plugins scripts, which will automatically show in Ultimaker Cura. Contributed by fieldOfView.
  • HP 3D Scan compatibility. HP 3D Scan Version 5.3.0 results can be directly exported to Ultimaker Cura application version 3.0.4 and later
  • Optimized workflow for crash reporting. Crash reports are automatically generated and allow the user, in case of a crash, to easily send their report with a description to developers.
  • New slicing features:
  • Floating models enabled. In previous releases, models were dropped to the build plate when support was disabled. Models now float when the setting is enabled (even if creates an impossible-to-print situation). This can be used to stack separate models on top of each other.
  • Slicing tolerance. A new setting that affects the intersect point to influence the dimensional accuracy for diagonal surfaces. The user can select the behaviour: ‘Inclusive’ makes gaps narrower, ‘Exclusive’ makes gaps wider, and ‘Middle’ is previous option, and also the fastest to process. When using ‘Middle’, the first layer will be taller by half of it’s height to compensate for the added half layer. This can be used to create better tolerances for test fit parts. Contributed by BagelOrb.
  • Optimized zig zag patterns. Zig zag patterns now print more consistently. Lines now have a 5 micron tolerance in which they are printed any way, resulting in longer connected lines. Contributed by smartavionics.
  • Aligned z-seam inner wall moves. Inner wall travel moves are aligned with the z-seam. This reduces the number of travel moves and reduces the chance of more unwanted seams.
  • Relative positioning of infill patterns. Infill patterns are now positioned relative to the center of loaded models. Whenever you load the model, the infill is positioned the same. An offset can be applied to control the infill more precisely and adjust it to preference or strength. Contributed by smartavionics.
  • Line resolution. Enables the user to specify the minimum allowed distance value between two points in G-code to create lower or higher resolution polygons.
  • Custom mode changes. If profile settings have been modified in recommended mode under custom mode, a reset icon will appear to notify the user. Click the icon to show the changes that have been made, and revert back to the default profile settings.
  • Bug fixes:
  • Fix for layer numbers being displayed incorrectly when switching between solid and layer mode
  • Fix for Cura Engine crashes during slicing if Optimize Wall Printing Order setting was enabled
  • Fix for uninstalling previous versions of Cura on Windows platforms
  • Fix for displaying visible settings
  • Fix for importing legacy .ini files
  • Prevent skipping user agreement dialog by pressing escape

New in UltiMaker Cura 2.7.0 (Aug 31, 2017)

  • NEW FUNCTIONALITY:
  • Relative Z seam. Make the Z seam relative to the bounding box of the model, so that the seam stays at the same location no matter what the position of the object is. Thanks to smartavionics for contributing.
  • Top surface skin. Specify print settings of the top-most layers separately in order to decrease print duration and achieve higher quality top surfaces. Thanks to BagelOrb for contributing.
  • First layer line width. A multiplier setting for the line width of the first layer of a print. Multiplying line width gives less lines but with greater width, which improves build plate adhesion. Thanks to 14bitVoid for contributing.
  • Set horizontal expansion on initial layer. Adds functionality to change horizontal expansion on the initial layer to compensate for the “elephant’s foot” effect. Thanks to fieldOfView for contributing.
  • Skin lines corner efficiency. Selects a better corner to start printing skin at to reduce the number of times the skin needs to be split to avoid causing a visible seam.
  • Ironing (a.k.a. Neosanding). Finishes prints by pushing the heated nozzle over top surfaces with reduced extrusion. Thanks to Neotko for contributing.
  • Plugins moved to server. All current plugins shipped with Cura are placed on a server. This allows the user to view, download and install all available plugins from within the plugin manager.
  • Standby and resume temperature. Turns off the extruder when printing with extended pauses to avoid filament burning and nozzle clogging. Thanks to JPFrancoia for contributing.
  • Easy plugin installation. Implemented a plugin browser to download and discover new plugins. This also includes a file association for plugins (using extension “.curaplugin”). Plugin files are contained in a .zip file which contains all necessary files. Plugins can be installed by dragging and dropping files onto the Cura virtual build plate.
  • Prime tower purge. In order to prevent under extrusion when printing a prime tower, and to prevent a prime tower failing half way through a job, a feature has been added to wipe off oozed/purged material in the middle of a hollow prime tower before starting to print the next layer of it. The amount of material to purge can be specified in the “Prime Tower Purge Volume” setting.
  • Extruder per feature. Assign an extruder to print a particular feature, including infill, wall, outer wall, inner wall and skin.
  • Print thin walls. Print object walls up to two times smaller than the nozzle size. Thanks to BagelOrb for contributing.
  • Gradual support infill. Supports print with gradually increasing density in order to reduce the print time and amount of material used. This is useful when printing with more expensive materials such as PVA.
  • Support infill layer thickness. Users are able to configure “Support infill layer thickness” for thicker support layers. This uses less material, while improving overhang quality.
  • Reduced skin splitting. Selects a varying corner to start printing skin at in order to reduce the number of times the skin needs to be split. This prevents any unsightly visible seams in the model. Thanks to smartavionics for the contribution.
  • Cura data collection. Collects slice data from Cura database so that it can be processed by a business intelligence tool.
  • Add optional extruder type. Includes the option to override the default extruder that is designated to print infill/skin/walls if necessary.
  • NEW UI FEATURES:
  • Dark theme. A dark theme in Cura. Ideal for low light environments. Thanks to fieldOfView and rudowinger for contributing.
  • Top navigation bar. “Prepare” and “Print” have moved from the right side of the top navigation bar to the left side.
  • Increased scroll speed in the settings list. The side bar scroll speed is now three times faster when scrolling through settings. Thanks to tsaaristo for contributing.
  • New hotkeys. Implemented keyboard shortcuts for "move" (q), "rotate" (z), and "scale" (z).
  • Dialogs for high DPI screens. Fixes some large dialog boxes on high DPI screens and aligns infill icons to the select boxes. If the text is too big, it will overlap but the icons will remain aligned.
  • Theme inheritance. Themes no longer have to be complete; they can simply inherit features from a default theme. Thanks to fieldOfView for contributing.
  • Interface elements upgraded to PyQt 5.8. When starting Cura, screen is rendered using PyQt 5.8, so the interface can load elements for extruder per feature.
  • Dual extrusion forbidden zones. In older versions of Cura there are “forbidden zones” on the build plate that do not correspond to print head position. This has now been fixed.
  • Zoom towards mouse cursor position. New option to zoom towards the mouse cursor position to reach specific parts of the build plate more easily. Thanks to nallath for contributing.
  • Import SolidWorks files as STL. Plugin that enables SolidWorks files to be imported into Cura directly, where they are automatically converted to .STL format. This plugin can be found in the plugin browser.
  • Cycle interfaces hotkey. Cycle through interfaces using the tab key. Thanks to fieldOfView for contributing.
  • Descriptive tooltips. Adds more descriptive tooltips to the setting fields in machine settings. Thanks to fieldOfView for contributing.
  • Polish now supported. Polish language support added, which can be selected in the preferences menu. Thanks to "Jaguś" Paweł Jagusiak and Andrzej "anraf1001" Rafalski for contributing.
