/diy/ - Do It Yourself

what's the point of printing a skirt? It's in the "build plate adhesion" menu but that shit has nothing to do with helping the model adhere.
explanation I read online is something along the lines: "it primes the nozzle with filament and lets you see how the first layer is gonna go down". Cura already does a skidmark on the left hand side of the build plate anyway.
seems to me like this is a waste of time and plastic. do you guys print skirts?
does anyone here use rafts or brims?

sorry if this is retarded but I'm new to this and I'm questioning all these things that make no sense to me.
