The 

Multiple Extruders

 page has two settings that control how ooze & filament wipes 

are handled.

 

The 

Wipe Shield Distance

 specifies how far away from the part you want what is 

commonly known as an “ooze shield” to be placed around the part.  In a two extruder system, 
the unselected hot end will create this “shield” in order to avoid dripping or oozing plastic on 
other parts of the model.

 

Wipe Tower

 is used when changing extruders.  The active nozzle creates a tower of the 

specified size and will use it to wipe the nozzle in order to reduce the possibility of oozing or 
dripping material on the model while the other extruder is active.
