Printed it once just fine, even though I noticed the weirdness in the preview.  Next time I re-sliced it to try and make it go away, but it was still there, just different.  Caused the print to shift on one axis at the layer with the weirdness.  Confirmed the thickness of the pre-fail resulting print is 5.6mm - same as the layer where the preview shows strange infill.\r\n\r\nI checked the STL in netfabb and it didn't find any problems.\r\n\r\nHere's how it looks on the preview:\r\n![gigantic_infill](https://cloud.githubusercontent.com/assets/1469426/12481367/a295a136-c016-11e5-8383-14e06725a2e5.jpg)\r\n\r\nAnd the resulting prints (the one in white I noticed and killed, then pulled off most of the messed up part):\r\n![img_20160121_081238](https://cloud.githubusercontent.com/assets/1469426/12481415/fd88fd54-c016-11e5-9c19-24ec90946555.jpg)\r\n![img_20160121_081252](https://cloud.githubusercontent.com/assets/1469426/12481416/003c904c-c017-11e5-98af-b1c665cd5446.jpg)\r\n\r\nSettings file - refer to ones with \"weird_infill\" suffix...
