Top layer infill/outer shell glob issue.

I forgot to take a picture before heading to work. Just try to bare with me.

The picture below is one I got off the internet, the build table is not close enough to the nozzle for the first layer, etc.

What it does, is help explain my problem. When the print head goes to infill operation after doing the outer shell, the head will leave little raised areas or globs when changing direction. These globs are right where the infill and outer shell meets at. I'm thinking it's because of over extrusion. Question is how can I control that, other than tricking the printer in to think it's using a slightly larger OD filament (setting now is 1.74) to 1.75 or 1.76

Is there a way to change the direction in which infills for the top and bottom layers occur? Say the top layer is infill is printing at a 45 degree angle but I wanted 60. How could I go about changing that? With infill it's really easy.

Re: Top layer infill/outer shell glob issue.

Just rotate the part, then the exterior infill angle will change relative to the part

And for your question about over-extrusion, I would never try to make a decision on that based on the first layer alone. That is affected far too much by the first layer position. It would be better to print 20 or so layers of the part and then see if the 20th layer still looks over/under-extruded. If it does, then you may need to adjust something, but if it's only the first few layers that look bad, then it's probably just your initial nozzle position

I'm not worried about the first layer, It's the top layer. The picture is the only thing I could find to help illustrate the location of the "glob"
