Infill problems?

Using Slic3r 1.2.9, I sliced Yoda this morning for a test print. It was set to use two outer shells and a honeycomb
infill at 10%. I was surprised to find that the infill walls are two or three layers thick and the infill includes an inner
she'll that mirrors the outer shell. (See attached photo.). The result is very few, relatively thick internal supporting
walls instead of many more thin walls that extend clear to the outer shell.

Did I make some mistake with settings that caused this infill pattern, or is everything working as designed?

Thanks for the assistance,
David

Looks like the middle is a section of a giant honeycomb. Try 20%, or rectilinear.

Yes, clearly the infill is honeycomb... That was, after all the infill pattern I selected. And yes, I could switch to a different percentage or pattern, but neither would answer the question as to why the 10% honeycomb pattern is so thick, resulting in large hexagons. If the walls were thinner and there was no inner wall as I previously stated, the hexagons could have been much smaller, used a similar amount of material (ie, 10% infill) and provided a much better distribution of infill.

Set your infill extrusion width manually from the Advanced page.

Yes it looks like something is telling it a big width.
