The beta version of Ultimaker Cura 4.9 has landed. The release contains a bundle of bug fixes and feature improvements – including several to print visualization – increasing software stability, and further simplifying and streamlining print preparation as you continuously strive for first-time right results.

Under the microscope

Several new features provide a better, more detailed visual representation of how a model is printed, making it a snap to fine-tune settings and improve first-time right. They include:

  • “Line type” is now the default color scheme. This improves your user experience – as you will no longer have to manually switch to “line type” each time you enter Preview mode

  • An indicator now clearly shows a print’s starting point

  • The Z-seam is now clearly indicated in Preview mode. This ensures that you will know whether the seam will be sufficiently hidden in the end product

Thanks to BasF0 for contributing to this feature.

18 printer definitions added for third-party printers. This makes Ultimaker Cura more accessible to community users.

Bug fixes

The following bug fixes are available in Ultimaker Cura 4.9 beta:

“Connect top/bottom polygons” setting. We have fixed a bug in which this setting was unintentionally hidden when initial layer bottom layers are set to “concentric”.

Ultimaker Cura not slicing. We have fixed a bug causing Ultmaker Cura not to slice a model if one sub-model of a group was below the build plate

Security patch. Fixed a security vulnerability on Windows permitting the openssl library used to launch other programs. Thanks to Xavier Danest for raising this bug.
