I took this picture to show everyone what I mean when I talk about threading.
The black object came with the printer to show what the printer made before it was shipped.
The white object is my test print. While they look similar, I can separate the layers with my thumb nail, so they are not solidly fused as they are with the black print.
So my next print I will adjust the vertical print size so that the layers are more compressed. From the picture, you can see that I am very close to having it fully printing solid objects.
