The pattern I used in the picture posted was lines and you were correct about some types of infill (e.g. lines) print every other layer - I am now using grid which looks like lines, but prints the whole pattern on every layer. Lowering the speed to 60 mm/s also helped.

I can print walls at 90 mm/s without any problems, but not infill at 90 mm/s. This doesn't make sense to me - why can't the infill be printed as if it were a wall (i.e. solid)

I have a 0.4mm nozzle and I have left all line width settings at 0.4mm. I have tried increasing the infill line width to 0.5mm and 0.6mm, but that doesn't do anything other than increase the infill line distance.
