Slicing fail

Hi,

I have another weird problem with a model here. Cura 13.06.5 (Mac). I sliced a part for this model:

There are four guns for the mech and somehow Cura decided that two of them should have a broken and displaced barrel:

 

Of course I noticed it after a 6 hours print :/

Gcode:

The other two guns came out alright. I wonder what caused it for the other two. Before adding the model to Cura I opened it in netfabb Basic and repaired it.

Look at it in xray view in cura. If you see *any* red then technically the model violates standards for what is okay in an stl file.

Having said that, you will probably want to fix this using the "fix horrible" settings. Or seriously consider using an older version of cura that could handle "bad" stl files better: 13.04.

Ok, I need to remind myself to properly check every detail in Cura before I start long prints. I usually look at it in the layers view mode. But it is hard to spot errors that way. I will remember to inspect it in x-raw view mode.

@daid: Maybe you could consider another mode like the Repetierhost gcode view.
