After printing about 20 items which printed correctly, this is occurring (picture attached).  The filament is not reaching the plate.  It appears to be distributing the right about of filament, but it does not reach the plate.  I have run the calibration test and cleaned the nozzle.

Adjust your Live Z setting

If you have not already done so, try using Jeff Jordan's "Life Adjust" procedure for calibrating your Live-Z setting. It is much easier to use and understand than the on-board routine and much easier to make mid-print adjustments accurately with. In general, start high (less negative) and work lower (more negative) in large increments (e.g. 0.1mm) until the filament starts to stick on its own. When you've got your Live-Z setting adjusted properly, you should be able to gently rub the extruded lines on the PEI surface without dislodging them.  Then start lowering (more negative) the level until there are no gaps between layers. You should not be able to peel the lines apart after printing, but the top should be regular.
