[Holes in Print]

That pattern is classic underextrusion which can have many causes.

Nozzle size .06mm?  That sounds like the problem right there.  Maybe you want 0.6mm?  If you truly have a .06mm nozzle then you need to either make the layer height smaller or the print speed much slower.  Or maybe you have a .6mm nozzle but put .06 in the slicer (this print would take days I suspect if you did that).

Are you using cura or a different slicer?  Which version of the slicer and what kind of printer?

My apologies. I am using a 0.6mm nozzle. That was a typo. I am using Cura 15.01.4 and an Ultimaker 2 that has been upgraded to an Ultimaker 2+. Additionally, both the shell thickness and nozzle size were input as 0.6.

Thank you.

I'm using Innofil Pro PLA at 230 degrees. I don't need super high quality or strength but I'm not sure why there are patches missing. Any ideas?
