Posted · Help with Cura on OSX 10.7.4 - slicing errors


I have problems slicing a model in cura 12.08 using Mac osx 10.7.4.

when i try to "Slice to GCode" i get an error saying:

"Something went wrong during slicing!", the log reveals:


File /Applications/ReplicatorG/examples/hexagon.stl is being chain exported.

Exception traceback in getModuleWithDirectoryPath in archive:

Traceback (most recent call last):

File "/Applications/Cura-12.08/Cura/cura_sf/fabmetheus_utilities/archive.py", line 244, in getModuleWithDirectoryPath

folderPluginsModule = __import__(fileName)

from fabmetheus_utilities.geometry.geometry_utilities.evaluate_elements import setting

ImportError: No module named fabmetheus_utilities.geometry.geometry_utilities.evaluate_elements

That error means; could not import a module with the fileName carve

and an absolute directory name of /Applications/Cura-12.08/Cura/cura_sf/skeinforge_application/skeinforge_plugins/craft_plugins


i tried various python 2.7.3 versions: the osx-shipped python 2.7.3, macports python 2.7.3 and the one manually installed one...

with all versions i get the same error.

what is wrong?

tanks for any help.

    Can you check if you have the directory:


    It tries to find the files in there, and it cannot, that's why it is giving that error.

    The file evaluate.py and evaluate_elements folder exists under these pathes:



    Content of evaluate_elements is:

    -rw-r--r--@ 1 inx staff 0 Jul 6 14:34 __init__.py_

    -rw-r--r--@ 1 inx staff 2110 Apr 3 2012 creation.py_

    -rw-r--r--@ 1 inx staff 3132 Apr 3 2012 document.py_

    -rw-r--r--@ 1 inx staff 6751 Apr 3 2012 setting.py_

    There shoudn't be underscores after those filenames... any idea how those got there? They are without underscores in the package. (Should be .py not .py_)

    i was wondering about these underscores... but left them on.

    just unpacked the package osx64-Cura-12.08.tar.gz again using "The unarchiver version 3.3", browsing to the same folder shows me the files with underscores...

    unpacked them via command-line and the underlines are not there...

    so "The Unarchiver" did manipulate the files?!

    Tried again unzipping the tar.gz in the command-line first, and then using "The unarchiver" with the left over .tar file.

    This did work.


    Using the freshly unpacked archive without underscores worked.

    You're welcome. I recommend you report this bug to the creators of Unarchiver. Seems like a nasty one.

    appended Underscores in "The Unarchiver" are a known problem in Version 3.3

    http://code.google.com/p/theunarchiver/ ... %20Summary

    should be fixed in the next update of that app.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
