Waves on large flat tops

[SHoutzager]

Getting fairly consistent prints with my Replicator 2 except for when I have large flat top surfaces. Either on the front or back I will get an area of waves. The rest of the top will print fine. As you can see in the link below I started getting waves and stopped the print. I just leveled the build plate and tightened up the belts. I hear a clicking sound when I do flat top surfaces.

Thanks!

my guess:
the clicking sounds are the filaments slipping in the extruder
less filament makes the roof thinner and the waves show up

slow the feed rate down a little, or thicken your roof

Hmmm. Not sure how to slow the feed rate. I can slow the print speed. Is that what you mean? It is already fairly slow. Not sure how to thicken the roof up with makerbot desktop. I did clean out the gears in hopes of smoother output.
