Seems unnecessary travel pattern along printed parts

Recommended Posts

Hi all,

 

Thank you for reading this. I'm trying to understand the travel pattern of Cura. I'm using 3..6, trying to print a spring of a toy bike.

What I understood (I hope) is that cura tries to print the inner wall then infill, so it has to move around.

But, why it has to move in the pattern as if it's trying to avoid the printed parts???

And even more... it dosesn't matter if I disable the "avoid printed parts when travel" option.

 

Thanks in advance.

 

Jia

Thank you all. Combing does have an impact on this. It's interesting to find out.

"Not in skin" does not work in this case, since the spiral path is "skin" after all. 

@smartavionics I agree that there should be an upper limit. I thought the "Max Comb Distance With No Retract" was the limit... but it seems it only impact the "retraction"... not the travel...😂

Is it? I can't tell from your images. Even if that spiral does contain skin areas, there is still a gap between the skin and the outline so the "not in skin" combing will travel within that gap.

I think I used the wrong words... it works as intended. but just not my expectation. 

It does travel within the gaps. regarding this, the avoid distance doesn't seem to work.

Please see the attached image, I tried to set an ... really large distance, but it still travels within the gap.

What I expected was following, when I set to "Within Infill" or "Off".

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
