Sometimes you will see small holes in your print when viewing the first few layers. This can happen if your line width is set too high. Too high? Wouldn’t I need to increase my line width to cover more of the surface?

Running your parts with a thick line width will cause larger gaps in the “corners” where the nozzle steps over to the next line to lay down. I usually don’t worry about it too much. In most prints, these holes don’t matter and eventually get filled in anyway. However, in cases where it matters, just reduce your line width. Or, even better, replace your nozzle with a smaller nozzle.
