Faster start-up. Start-up speed has been cut in half compared to the previous version.
New color scheme. Color scheme has been updated.
Updated UI design. The Ultimaker Cura logo has moved from the bottom to the top of the interface. Print status icons have been updated and repositioned.
Redesigned splash screen. A new splash screen on Ultimaker Cura startup has been added.
Top navigation bar improvements. The width of tab functionality changes accordingly to the word space (multilingual).
Print quality slider. A slider can now be used to control the quality profile in recommended mode.
Infill slider. Model infill can now be changed using a slider in recommended mode.
Changed layer view. Layer view icon, panel and slider have moved to top-right of interface.
Rasterized build plate. The build plate now shows graduations of 10 mm and 1 mm for easy model positioning.
Changed row of extruder buttons. Extruder tabs have become buttons and icons have been updated.
Add an "Export to Ultimaker Cura" button in SolidWorks. SolidWorks plugin can now be installed using an automatic installer.
Siemens NX macro. When a user updates models in Siemens NX and clicks the button, the updated models replace the models opened in Ultimaker Cura.
Skin removal width. Remove thin strips of skin from a model to prevent print head zigzagging, in turn preventing vibrations.
Skin expand distance. Cutting away skins on steep overhangs makes prints less sturdy. By expanding skins with the thickness of walls, features will be better supported. In addition, features such as towers on top of infill will be stronger.
Extra skin wall count. Printing extra skin directly on top of infill can lead to gaps, curling and pillowing. This is reduced by printing a wall around the skin first, and also improves the printing speed.
Minimum extrusion for skin. Will prevent filling small gaps that are probably filled already, resulting in less strings, better top details and faster prints.
PVA retractions. PVA (switch) retraction length is increased, minimum travel distance for retraction is decreased and max count is slightly increased, this reduces stringing by a lot at the cost of slightly increased print time.
Z seam options. Gives the user control over where to place the seam - hide it in convex corners or in easy to remove locations such as concave corners. Don’t let corner angles influence the seam position.
Quarter cubic infill. Similar to tetrahedral (octet) infill, but half of the lines are shifted half of the period up. This pattern sacrifices some rigidity of octet infill for greater toughness.
Cross infill. A fractal pattern infill that requires fewer retractions than other infill types. This is useful for flexible materials as it causes less material elongation. The internal structure given by this infill also assists flexible models having more resistance, while retaining ‘soft’ properties in all directions.
Layer start negative position. Layer start X/Y values can be less than 0 when the machine center is zero.
PostProcessing stretch script. This new script performs "post stretch" algorithm to fix the problem of insufficient inner and outer diameters. Thanks to electrocbd for contributing.
Ironing speed settings. Ironing speed settings have been moved to experimental category.
Doodle3D plugin. Update Doodle3D plugin to connect with printers. Thanks to mith for contributing.
Several bugs have been fixed related to:
Cura 2.7 - August 30, 2017
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.
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), "scale" (a), and "rotate" (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.
Simplified Chinese now supported. New translations for simplified Chinese added. Thanks to jockeysoft for contributing.
