Cura 13.10 - Head wanders off into infinity

[gadgetfreak 7]

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 any help,

I think this also relates to the model, as I do not get the same problem with the same profile. Can you share it?

 

[gadgetfreak 7]

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 :-)

 

[ian 32]

actually i can check it now at the moment.... very very sleepy office... Yawnnnn

 

[Daid 306]

Email is fine, d.braam@ultimaker.com, I'll delete the file and do not share it with anyone else (which is my default procedure if I do not get explicit permission to share the file)

 

[ian 32]

or send it to me and i will secretly sell it to my friends in Saudi Arabia for... 1 million euros... WOHAAAA... ;-)

Ian :-)

 

[gadgetfreak 7]

No confirmation from my customer, I'll get back as soon as I've heard from them.

It looks like the bottom of your part is a "shell". Maybe you could just send Daid the bottom 1mm of the part somehow. The bizarre thing is the skirt seems to be both inside and outside the part!

 

[gadgetfreak 7]

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).

 

[Daid 306]

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.

 

[gadgetfreak 7]

I did change it by 1mm up and down and to completely different cutoff points but not in 0.1mm changes. The ones I tried all gave the error. I hope I can supply you the model tomorrow or this week at least to test with. Thanks.

[gadgetfreak 7]

I was allowed to share with you Daid and I have sent you an e-mail now

 

[ian 32]

my Arabian friends will not be happy.... :-(

I have failed once again.......
