I like to print infill every other layer to save time, but I've noticed that in this circumstance, the infill is printed very sparsely; often an infill line will barely touch the lines under it. In cases where I use a very small layer height like 0.08 and print infill only every three or four layers, the infill can break down entirely. Here's a picture that illustrates the layers of infill barely touching the ones beneath them with 0.15 mm layers and infill every other layer: http://www.flickr.com/photos/18245812@N00/6339039117/

Here's the profile I used: http://pastebin.com/1PPKarx4

… And here's a zip of the profile, .stl, and generated .gcode file: http://techpaladin.com//wp-content/uploads/random/vanderbilt_issues.zip

It seems like the flow rate of the infill needs to be increased a bit to ensure that enough of it is laid down in a way that it can properly support the next infill layer.
