UltiMaker Cura 5.8.0-beta.1

New features and improvements

New Z Seam Settings

New settings have been added that let you tweak how and where the Z seam is placed

• "Z Seam On Vertex" allows you to choose if the Z seam is placed on the vertices closest to a selected Z seam position or if it instead follows the selected position exactly
• "Seam overhang angle" enables you to select the angle at which Z seams will not be printed on overhangs, resolves #9369
• "Support Z Seam Away from Model" and "Min Z Seam Distance from Model" define where the Z seam is placed on supports

Try it for yourself with this toast post-it holder.

Newly introduced Settings

• “Support Infill Density Multiplier Initial Layer”, “Raft Infill Overlap Percentage”, Raft Surface Z Offset, and Raft Flow settings to improve dual extrusion rafts
• “Cooling during extruder switch" to define the cooling fan behavior during an extruder switch by defining Unchanged, Only last extruder, All fans
• Updated the "Interleaved Prime Tower" with "Prime Tower Minimum Shell Thickness" so it uses less filament, contributed by @wawanbreton

Other Improvements

• A search bar has been added to the “Add an offline printer” list, resolves #16716
• Updated the retract behavior for a nozzle switch to reduce the chance of oozing
• Updated Insert at Layer Change Post Processing Script so layers can be skipped, contributed by @tastyratz

• Fixed a bug that caused spiked objects to have missing layers, thanks to @ThomasRahm
• Updated the text in the Open Universal Cura Project (UCP) file to be more correct
• Fixed the interpolated values for fan speeds and improved the check for minimum layer time, resolves #5409
• Fix a bug where material_print_temp_prepend not being disabled, resolves #19204
• Reduced the chance that oozing in the first travel move will cause a scar on the bottom of the model by updating the Layer Start X and Y, resolves #19156
• Fixed a bug where a slice would fail if the overhang angle was set to 90 degrees
• Fixed a bug where infill lines are going through the model with a certain setting combination, resolves, #18970, contributed by @ThomasRahm

Known Issue

On our UltiMaker Method series machines:

1. Some raft-related values might initially appear incorrect in the printer settings list; but rest assured, they are correct and you can see them show up correctly when you refresh the fields by Collapsing All Categories with the hamburger next to the search and search for your setting again.
2. If you are experiencing some trouble having the model material stick to the PVA in the default settings, you can consider updating the support top distance 0.4 --> 0 and support roof line width 0.25 --> 0.4
