ULTIMAKER CURA 4.8 beta

ULTIMAKER CURA 4.8 beta

We are happy to share Ultimaker 4.8 Beta with you. It marks a new step in the evolution of Ultimaker and perhaps the world’s most used slicer. You can help to make it even better for yourself and all its users by taking part in this Beta and report your findings back with us. 

So, what new features can we share with you today?

 

Arrange models has been improved.
Until now, the arrange models feature didn’t always utilise the available bed space to its fullest, which made a lot of users arranging their models by themselves. An improved arrange models feature should provide you with your assistance from now on. Parts are automatically more tightly packed, using the full available space on your build plate.

And we shouldn’t neglect to mention that this feature was developed with the power of the open-source community. A big thank you to Prusa Research, who developed the open-source library used to creature the feature’s improvement. 

 

The cool side of the build plate.
Ultimaker Cura will now show your model, or part of your model in a different color when it reaches below your build plate. This should help in creating a more visual guide which part of a model will be cut off and therefore not printed. 

 

Loading project files. 
When you load a new project file, you can now select with which printer type you want to open this project. You can still choose to open it with the printer type it was originally sliced for, but you have the option to select a different printer type too. 

 

Bug fixes included in Ultimaker Cura Beta 4.8:

 

Measurement units correctly applied.

Previously, when changing percentages, the wrong axis would be scaled, resulting in a broken model. This has been fixed. 
 
Artifact removal in curves.

Fixed an issue that left tiny artifacts in certain curves, causing the print head to slow down. This results in smoother print surfaces when printing such curves.

Highlights

New arrange algorithm!
Shoutout to Prusa, since they made the libnest2d library for this, and allowed a licence change.

When opening a project file, pick any matching printer in addition to just exact match and new definition.
Previously, when someone sent you a project, you either had to have the exact same printer under the exact same name, or create an entirely new instance. Now, in the open project dialog, you can specify any printer that has a(n exactly) matching printer-type.

Other Features

Show warning message on profiles that where successfully imported, but not supported by the currently active configuration.
People where a bit confused when adding profiles, which then didn't show up. With this new version, when you add a profile that isn't supported by the current instance (but otherwise correctly imported), you get a warning-message.

Show parts of the model below the buildplate in a different color.
When viewing the buildplate from below, there's now shadow visible anymore. As this helped the user determine what part of the model was below the buildplate, we decided to color that part differently instead.

Show the familiar striped pattern for objects outside of the build-volume in Preview mode as well.
Models outside of the build-volume can of course not be sliced. In the Prepare mode, this was already visible with solid objects indicated in the familiar grey-yellow striped pattern. Now you can also see the objects that are still in the scene just outside if the build-volume in Preview mode.

Iron the top-most bottom layer when spiralizing a solid model, contributed by smartavionics
Ironing was only used for top-layers, or every layer. But what is the biggest flat surface in a vase? This helpful pull request made it so that, in this case, the top-most bottom layer is used to iron on.

Allow scrolling through setting-tooltips, useful for some plugins.
Certain plugins, such as the very useful Settings Guide, occasionally have very large tooltips. This update allows you to scroll through those.
