4.7.0

Ultimaker Cura 4.7.0

Highlights

Rotation widgets
fieldOfView has contributed code that adds 3 pairs of arrow widgets to the Rotate tool handle, to rotate objects by exactly 90 degrees.

Performance improvements with multiple 3D models
In previous versions many objects on a build plate could cause Cura's performance and response to be slow. We have made some code optimizations to increase the responsiveness of Cura in such cases.

Cloud connections improvements
Improved the overall UX workflow when a user is using a cloud connection. Check our new enhancements below.

Moved tree-support from experimental to normal settings
We've made stability fixes and tested thoroughly so that it can be considered stable.

Improve object list GUI
The object list indicates now the extruder used for each model, the mesh type if the model is not a normal mesh, and the number of per model setting overrides and whether a model is outside of the build plate. Contributed by fieldOfView.

Other Features

Support for MacOS Big Sur
Ultimaker Cura will now run on Apple's upcoming operating system.

Change normal support vs. tree support into a drop-down
There is now the option of easily switching between normal and tree support. You cannot enable both at the same time any more.

Add "Multiply model" to Edit menu
The option is now also accessible in the Edit menu and not only in the context menu (right-click).

Add local printer improvements
Whenever the user wants to add a non-networked printer it is now easier to distinguish the scrollbar and some more information regarding the selected printer in our new redesigned layout. Have a look yourself! Brought to us by fieldOfView.

Show all while searching per object settings
For more ease-of-use, the behavior has been changed so that all settings are visible temporarily, even if initial were hidden.

Search through setting descriptions
When searching through the custom settings, the results include all the matches found in both the setting names and setting descriptions. This makes some settings easier to find if you don't remember the name.

Check for account updates manually
A check for update/sync/refresh button was added near the account so that the user can manually check for updates of subscribed Marketplace packages and available Digital Factory printers.

Always select last write-device
Cura will now remember the last used output device to save the g-code to (to file, USB stick, etc.) Contributed by fieldOfView.

Improved sync with the Ultimaker Marketplace
Profile picture and links to the Digital Factory have been improved in the account dropdown.

Add option to sign in with another account while looking for cloud printers
The "Sign in with a different account" link logs the user off both from Cura and the browser, so that they can sign in with another account. In case the other account has extra cloud printers, then these printers are added to Cura and are available for use.

Show warning in printer management page that removing is temporary
When removing a printer in your Digital Factory, a message pops up to inform the user that the printer will be re-added in the next sync.

Show cloud connection not available
We now display an offline icon when losing connection to a printer in the Digital Factory.

Show notification when printer is removed from account
We show a notification when a printer is removed from the account. You can either go to the account page to restore access or remove it from Cura. In order to establish a new connection, the user is directed to the Digital Factory.

Add an offline printer, linked to an account, to Cura
Printers that are temporarily offline (but previously added to your account) will also be added to Cura. You won't be able to send a print to that printer, but you could slice for it and store the g-code elsewhere.

Adjust initial layer horizontal expansion
We adjusted the initial layer horizontal expansion for some profiles. This compensates for Elephant's Foot, a small defect where the bottom of the print has a little ridge where it is molten to the build plate.

Allow a g-code to be inserted before or after pausing
It allows the user to enter a custom g-code before and after a pause at height. Contributed by rodrigosclosa.

Remove package ratings
The package ratings have been removed from the Marketplace.

Remove extra skin wall count in concentric
Hide "Extra Skin Wall Count" setting if a concentric pattern is used, and don't let it affect the print any more.

Support Stair Step Minimum Slope Angle
With this setting you can disable stair stepping on the very bottom of the support, up until the slope of the model has a certain angle.

Pause at Height scripts combined
Instead of having various scripts to use for different machines, there is now just one Pause at Height post-processing script, so all printers can now have the same features when pausing. Contributed by fieldOfView.

Pause at Height limited to 1 redo layer
The "redo layers" setting is replaced by a checkbox to redo just the last layer, to prevent colliding the print head with previously printed layers.

Change at Z improvements
Added support for changing Retract Length and Speed and fixed an issue when multiple changes are stacked on top of each other. Contributed by novamxd.

Add post-processing script display progress on LCD
The "Display Progress On LCD" post-processing script shows the time left and the percentage on their LCD screen. Contributed by Bostwickenator.

Add preference for single instance
If enabled, only one instance of Cura will be started at a time. Contributed by fieldOfView.

Remove spaghetti infill
This setting was rarely used and didn't work well.

Bug fixes

• Fixed issues with support no longer generated on some parts of the model. Support Stair Steps has caused some support to be missing where it touches the build plate or where it's resting on a shallow surface. It should be complete again.
• Fixed multiple different issues with tree support, where branches would intersect with the model, the wouldn't keep distance when resting on the model, or when printing with Spiralize mode.
• Fixed an issue where Cubic Subdivision infill didn't move along with the model.
• Cubic Subdivision will now rotate according to the Infill Line Directions setting. Contributed by smartavionics.
• X-ray view is now red again, instead of translucent green.
• Improved wording of the "Discard/Keep Changes" dialog for clarity.
• Models assigned to extruders >4 are visible again in layer view.
• Fixed an issue when importing images if the "Base" setting was greater than "Height".
• Cura now outputs a command to cool down the build plate for the second object in one-at-a-time mode even if the Initial Layer Build Plate Temperature is 0.
• Distance between infill and walls and between infill and skin is corrected when using Infill Layer Thickness.
• Fixed a crash when Coasting Minimum Volume is set to 0.
• The usable build volume will no longer be shrunk unnecessarily when not using any adhesion, but using a prime tower with a brim.
• Fixed a slicing crash when combining Randomize Infill Start with an even number for Infill Line Multiplier.
• Improved reduction of model resolution. The Maximum Resolution and Deviation settings should now be more accurate and no longer behave differently in one corner of the model.
• Removed an unintended gap when something was resting on an ironed surface.
• Fix skirt printing out of order, causing unnecessary travel moves. Contributed by smartavionics.
• A fix was added by smartavionics which removes unnecessary long moves that travel towards the outer wall.
• It wasn't possible to connect to a network printer if two network plugins were enabled simultaneously. Now made possible by Loociano.
• Support settings are now visible when you have support disabled, but a support mesh is present in the scene. Fixed by fieldOfView.
• Fix printing speed after performing a retraction when using the stretch post-processing script. Contributed by sgtnoodle.
• Prevent tool panels from overlapping with scene information. Fix made by smartavionics.
• The values of the machine settings would look cut-off on some Linux distributions. Now fixed by smartavionics.
• Fixed settings sometimes not appearing if they belong to a checkbox setting that is enabled by default (e.g. retraction settings belonging to Enable Retraction).
• We cleaned up our “About...” dialog. It is now up to date.
• Improve performance of loading profile metadata. This fix improves the start-up time of Cura.
• When loading images, the translucency and linear options were swapped. Translucency should now again be tuned for lithophanes, and linear for a height map. Contributed by michalsc.
• Retractions in travel move to next layer were sometimes omitted, but that's fixed now. Contributed by smartavionics.
• Fix initial layer thickness when empty initial layers are removed. Contributed by smartavionics.
• If Brim Replaces Support is enabled, the brim will now also replace support interface.
