Larger Prints Possibly Underextruding?

[crystalsdg 0]

Hello,

I have the ultimaker extended 2. Have done some test prints that came with the sd card (voronoi heart, Earring circle) which all printed fine. I'm trying to print something a bit larger (as pictured in the cura format photo above) but everytime, some part of the print, the filament comes out jagged. I have tried the atomic method to clean out the nozzle, re leveling the build plate, and adjusting the material feeder in the back. The results are always the same. Somewhat jagged thin pieces of filament (though not everywhere). Completely lost, any ideas on troubleshooting this issue? Thank you in advance for any help!

Hi,

Although it looks like underextrusion, maybe there is an easier explanation. It might be that the second objects floats above the print area. Check out the layer preview and start from the bottom to the top.

Thank you nicolinux! I created the file in rhino, and going back into that file, I realize not all the polysurfaces align at the bottom plane, small minor discrepancies but there nonetheless. Am fixing it now and have a hunch that it will fix the problem.
