UltiMaker Cura 5.11.0-beta.1

New features and improvements:

A new set of paint-on features designed to give you more flexibility and control when preparing your prints:

Paint seams directly on your model to define where Cura places the z-seam, or block areas where seams should not appear. Paint extruder assignments for multi-material printing. Easily designate different regions of your model to different extruders with a simple brush workflow. These new painting tools make it easier than ever to fine-tune the look, feel, and performance of your parts.

Try it for yourself with this Painting Easel Test.

UltiMaker’s newest professional printers the UltiMaker S6 and UltiMaker S8 get even more powerful . Expanded print core support: slice with AA 0.25, AA 0.4, AA 0.8, CC 0.4, and CC 0.6 cores. Improved material quality: PLA, Tough PLA, ABS, and PETG profiles now produce smoother surfaces, stronger parts, and better dimensional accuracy. New draft intent profiles: faster printing options for common materials, optimized for productivity.

If you were not using the USB-Cable Printing in the previous (5.10) version of Cura, it is automatically disabled for them. In addition, an option is added to the Cura Preferences under General where user can easily Enable or Disable the USB-cable printing by checking, unchecking the setting and restarting Cura.
