Do Z-hop when retracted

The do z-hop when retracted flag is the flag which switches on/off a nozzle z-hop mode when travel has retract. Choose this mode to improve external shell surface quality, but keep in mind that it sligtly slow down print process. Besides, it may produce strings between print areas, but usually it is easier to remove them than plastic drops.

Avoid crossing borders

The avoid crossing borders flag is the flag which indicates that border crossing minimization mode in on. It means that if it is possible to travel from one print area to another without crossing borders, that path will be chosen instead of direct path with borders crossing . This mode increases print time, but improves external surface quality.
