Bad Infill, clicking, but fine outline?

[Bassna]

Last night I was printing something and when it's doing the infill, it's making a clicking noise when doing it. The outline looked fine, and the print still came out looking fine. But the infill was very shotty.


Not much different than I usually print infill, Simplify3D, with these settings.

I tried changing the temp pretty high while it was printing, and it was still doing it. I'm thinking maybe there is a small clog in the extruder? When I get home today I plan on taking it apart, I have yet to have to clean it out or have it jam on me, so maybe that could be the issue?

Thanks!
