I'm pretty sure it's both normal and correct. 50% means there is just as much plastic as air - that's pretty dense. When you hit infill 25% it changes the algorithm. I recommend you stick at 24% or lower for most parts. In fact most things don't need any infill but could use a thick shell. The shell is the most important region for strength.
Ah, thanks for the explaination, that was another thing I was going to experiment with to figure out when it switches to use the alternating lines.
But that's the thing, I don't see any air between the gaps. I load it up in http://gcode.ws/ - to me the view of "just" the lines looks about right. But if you check the option to "Emulate extrusion width" it shows no gaps, it's pretty much solid.
Now that I think about it though, the gcode viewer is just looking at a "slice" of the slice, so you can't see the full "bead" of plastic. Is that part of the calculation, that even though each bead may be touching at the edges, there is still some gap/air around the corners? Wish I could upload a quick graphic to show what I mean in my speculation, hard to describe...
It just seems like such a huge change when switching from the grid to the lines. I would read up about it myself but my "google-fu" is failing me this morning, not sure what to call it when I search... I would totally accept that it's supposed to be that way, I'm curious about how it works though, love learning about how things work!
And thanks again for the really quick response and info!
