Bad Print Settings? - Nope......Nozzle

Lately I have been getting horrible prints. The problem was most evident in the sidewalls that were very irregular, wavy, rough, and very inconsistent; almost like fuzzy skin. The odd thing was the top and bottom flat surface area looked fine. In addition the infill looked very bad too; broken lines, gaps and any internal bridging often broke and failed to cover even short distances. Stringing was also very bad.

I went back to my tried and true filament, PolyTerra PLA, and tried to resolve the issue, printing a simple 25mm cube I changed temperatures, extrusion rates, speeds, etc.; and while some settings helped a little I could never resolve the issues.

Pictures here show what I was getting.
