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!
