Sparse spots on layers (1 reply)

Hi again. Anyone know what the deal is here:



This happens consistently at that spot on the print bed (and in other spots as well). I assumed it meant the rear wasn't high enough, so I tried raising it up. When I did that it was too high and the head started dragging along the plate. I backed it off a bit and ended up just re-leveling the whole bed but the same thing happens in the same spot(s).
