Slicing problem

[capitaenz]

Please look at pictures: I use Slic3r version 0.5.7

STL File:

http://mari-hh.de/files/1.stl

[alranel]

Can you please describe the issue more in detail so that I don't have to open the STL and compare it myself?

[capitaenz]

The object is created using Google Sketchup and exported as an STL. I can only say that the object is Skeinforge slicet correctly. Slic3r disappear with the details.

Did you run it through http://cloud.netfabb.com/ to fix it?

[capitaenz]

I've tried it. Here are the results: A hole is highlighted in red, but the program shows me there would be no error exists when it is saved. It should be error-free files can be generated, tells me netfabb. what makes me wonder is that skeinforge can create error-free file.

[Pointedstick]

Skeinforge is very tolerant of bad files. Ideally you should clean up the model so your slicer doesn't need to fall back on its STL repair code though.

[smartroad]

I use sketchup for many of my projects and find it can produce some bad STLs. I have even had Skeinforge complain when netfabb said it was okay. One of the steps I do now is make the object a component/group in Sketchup. I then found a plugin that checks that the object is a vaild solid with no duplicated faces or edges (which it highlights if there are). When i get on my PC I'll try and find out the plugin i used, maybe that will help?

[smartroad]

BTW what program are you using to view the gcode?

[alranel]

I'm closing this, since it's caused by a bad model (inspection with Netfabb reports bad normals).

[o-jasper]

Hmm i got stuff disappearing from slic3r quite a bunch of times, it is a very annoying problem.

It is fine you want slic3r to be sortah a one-task thing, but are you sure you cant help it more? Maybe give a better warning , for instance linking to documentation on how to avoid incorrect stls and how to fux them.

Edit: why are we using a format that can so easily be ambiguous anyway? (Is AMF any better in those terms) I can think of a format that cant be ambiguous; octrees with normals and inproducturs in each end cube. Probably easier to deal with too. But i wouldnt put that responsibility here :)
