Figure 37: First Layer is Too Close 

 

This image shows a first layer that is too close.  The infill traces are bonded to their neighbors, but we can see 

excess plastic that accumulates above the infill traces.  This is less of a problem than a first layer that’s too tall.  But 
in extreme cases, the print head and bed can be so close than no plastic is extruded at all.  This can cause problems 
with the extruder slipping or jamming. 

To correct this, the corner bolts should be tightened (threaded in clockwise). 

 

 

Figure 38: First Layer is Correct 

This last image shows a “perfect” first layer.  The infill traces are firmly bonded to each other, but we see no excess 
plastic building up between them.   

This graphic from MatterHackers may also be helpful in understanding what the first layer does:
