My printer (well, PrusaSlicer) always starts with a line around the object I am printing. See (1) in the image. –Why? What does that do?

There is also this line (2) at the front of the bed. –Why? What does that do?

    The line around the object I believe is meant to purge and fill the nozzle. Without it, there’s a chance you start printing and a big chunk of your first layer doesn’t have any filament.

      The second part is a nozzle cleaning. It wipes the nozzle on a part of the bed that won’t be used for printing to get debris off of it before printing. Cura does the same thing on my tevo tornado and actually sends a message saying what it’s doing so when I’m logged into reprapfirmware it says “cleaning nozzle”
