Thank you, I'll try that!

I also tried changing the print core because the one I was using was getting old. I'm printing PLA with a AA .4mm print core.

The type of printer I use is the Ultimaker and whenever I print a part, the bottom skin that usually has support has extrusion issues. Everything else in the print turns out fine but the bottom skin turns out terrible. I've tried adjusting my Cura print settings to where the bottom skin layer would come out okay. Nothing I tried worked. I have the Printing Temp set to 225, build plate at 60. Print speed set to 30. Here are screen shots of settings I have for the top/bottom layer as well as what my prints look like when they are finished.

I've been having the same issues. I've been printing with Black tough PLA. I've tried changing a variety of things such as Top/bottom settings, the temperature and flow but I can't figure out what's the issue. Any suggestions?
