ah ok, i still have the 5.13, rolling back

i opened your project but was still showing the unintended travel moves. by the way i do not want to print that particular model, i was just trying to understand

nothing, still those weird travels

Thanks for the links and inputs. As gr5 said this is a method of modelling for extreme lightweight parts, to be printed with LW-PLA that cant handle retractions. If you stumble upon 3dlabprint and Eclipson vase-mode models you will see much much much more complicated model than this...sadly for now, it looks like the only medicine is to switch to PrusaSlicer 😞

sadly the cure its worse than the disease, the autofix deleted some geometry (creating islands by the way) and there is still illness 😞

yeah, i see but in the model there are no islands, i checked it with a script very carefully, did you check the mesh before inputting it into Cura?

Hi i know uploaded a STEP, if you read the thread and the comment you would have realized. And you have the same problem as me, the mesh you created it's ill (see attachment). Its not simply "a cube" if you watch it carefully every slice its a closed perimeter, in the same fashion of the other model i uploaded in the thread. In other slicers (i do not know if i can mention them) the vase mode on this model work, i want to see if the mistakes of Cura are due to mesh errors or something deeper. For now i state my last question again: can somebody mesh the step (which is clean of errors) in STL without errors?

I tried another test, this works in others slicers, i do not know if the problems is my meshing procedure. Can somebody open this in a CAD, mesh it in STL and see if vase mode works?? Test_Step_AP203.zip

also the vase mode stuff from Eclipson (they are gurus at this, so model errors can not be taken into account) its not sliceable by Cura, they provide g-codes and they are perfect

do you have SW or Siemens NX?

do you have Rhino 7 ?

it is the result of an intersection, its normal the output is like that. Btw i uploaded the STEP file in a previous comment if you want to check it yourself

no, that's a closed NURB curve into the CAD software, what you see are the CV points...

i know, this is a section from the model incriminated, its 100% a closed loop, still it does not spiralize correctly and consistently

No, im not happy, i want to know what can be spiralized and what not, that one was only an example, what are the rules? It looks like that the perimeters are a closed curve its not sufficient, others rulse are into play. The piece i brought to the table was only for troubleshooting. I also tried different pieces from 3dlab and eclipson (sadly i can not share for obvious reasons) and they all have those weird travel movements 😞
