Cura 13.10 - Head wanders off into infinity

Recommended Posts

Hi,

I think I've found a bug in Cura 13.10 (sliced with Ultimaker 2 profile).

The head wanders off into infinity, see this screenshot:

The profile used is this (from the excellent new "Copy profile to clipboard" feature):

Thanks for quick response Daid. Unfortunately not since it's a customer project which I've been asked to keep confidential. But I will ask if I can share it with you only. If I can, how would you like to have it? Dropbox link or e-mail?

 

you can send me the stl Daniel if you want... i can check out the polygons tonight.

Ian :-)

I forgot to mention a pretty relevant thing...the object is pretty large, so in the error scenario I have sunk it into the platform with "Cut off object bottom (mm)" by 92mm.

The model needs a lot of internal support structure.

It seems to occur at many "cut off" heights.

The error occurs at the second layer.

However, when I slice the full model (i.e. when not using "cut off.."), the error is not there.

I have checked it it Netfabb and the model is "good" (no holes/bad edges etc).

Could be a bug in clipper. I just updated my development version of Clipper (library I use for lots of the heavy lifting) and the changelog reports a few bug fixes for rare bugs. You could try changing the cutoff point by 0.1mm to see if that causes a difference.

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
