Slic3r PE - can't load stl-file

Hello,

for testing purposes I genarated a simple quader (15 x 15 x 5 mm) in my CAD program (MegaNC) and exported that as an stl. Unfortunately Slic3r is not able to load it (error message: Loading of a model failed). Re-import into the CAD program works.
There are no specific setting in the CAd program to generate the export so I'm wondering what went wrong. Does anybody has a chance to look over the attached file and could give me a hint what's wrong?

Kind regards
Jürgen

Kind regards
Jürgen

Slic3r won't load this for me either. I ran it through Netfabb and repaired it https://service.netfabb.com/service.php - now Slic3r loads it. I guess your CAD programme does not produce good STL's.

Hello Olef,
thanks for your effort. That helps because now it's clear that this isn't a problem of the slicer. I'll contact the manufacturer of my CAD program.

Kind regards
Jürgen

Update: Problem solved - as usual, simple, but you need to know the triggers 😉
The STL standard setting of the CAD program was ASCII output, that needs to be changed to binary.

Kind regards
Jürgen

Re: Slic3r PE - can't load stl-file

I have same problem with Maya 2018 STL, Slicer won't eat them. Not Slicer's fault, export plugin has been broken for ages:

I've been using .OBJ, it works, but needs to be triangulated before export. Export plugin doesn't have an option to do it automatically when exporting which is annoying...

Re: Slic3r PE - can't load stl-file

The ASCII STL has an unusual format:

solid Quader
facet normal 0.00000000 0.00000000 -1.00000000
outer loop
vertex 0.00000000 20.00000000 0.00000000
vertex 20.00000000 20.00000000 0.00000000
vertex 0.00000000 0.00000000 0.00000000
endloop
endfacet 0

Slic3r refuses to import the STL, if there is the number after the endfacet word. It is a weird extension.
