Cura 2.7 is out

Post by LePaul » August 30th, 2017, 12:24 pm

Cura 2.7
Cura 2.7 - August 30, 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.

Simplified Chinese now supported. New translations for simplified Chinese added. Thanks to jockeysoft for contributing.

Third party printer support

Peopoly Moai definition. Thanks to fieldOfView for contributing.

Updates, profiles, extruder start positions, acceleration, and jerk control for Cartesio printers. Thanks to maukcc for contributing.

EasyArt Ares definition. Thanks to nliaudat for contributing.

DiscoEasy200 printer profile. Thanks to landru29 for contributing.

HelloBEEPrusa dual extrusion profiles. Thanks to macosfg for contributing.

Rigid3D start g-code. Thanks to Rigid3D for contributing.

Type A Series 1 printer definition. Thanks to fieldOfView for contributing.

101Hero build plate visualization. Thanks to rmcolbert for contributing.

Bug fixes

Cura 2.7 features several bug fixes related to:
Crashes on startup
Crashes when printing over network
Crashes when adding a printer that is not an Ultimaker 3
Calculating prime tower thickness and location
Camera view issues
Material profile visibility in custom settings
Displaying layers with Python 3.6
Changing certain settings that do not trigger auto slicing

True....but I saved you a click!

One problem I am having it 2.7 ....Octoprint. It tries to print as soon as the bed is to temp....not the print head!

Ah looks like it set back the Marlin gcode to Ultimaker2
