Cura 5.x Spiralize Mode Broken

Recommended Posts

Posted · Cura 5.x Spiralize Mode Broken

In Cura 4.x the attached file printed out great. After upgrading to Cura 5.x it is no longer possible to print the attached file. Screenshot attached with the result of the slicing. It is better with surface mode set to just Surface, but the horizontal surfaces are then not printed.

    If the model isn't solid through-and-through then spiralize will print the outer wall that is facing outwards, and the outer wall that is facing inwards.  That is not what you are looking for but Cura is trying to print the model you have open.


    You can enable the Mesh Fixes setting "Remove All Holes" to make the model solid so it has a single exterior surface.  That will allow spiralize to work.

    There have also been complaints about the bottom layer pattern in Spiralize.  There is only one option now and it is "concentric".  There has been a bug report opened on GitHub regarding that.

    Indeed the Remove All Holes setting fixed the double wall and the spiky interior, but the bottom is now solid where there should have been a lip.

    You might have to go back to 4.13 to fix that.  I've tried before and didn't find a way to put a hole in the bottom of a spiralized print.
