New to 3D printing, how can i print a test line before prints?

[TTVert]

It seems that none of my prints have that test line and I don't know if that is SOP for 3D printing but it seems that it somewhat cleans the print nozzle and allows for a clean base. I think it's called a skirt but is it something I need to manually add to the beginning of my g code or does the app usually add it for me?. If I don't have it the first line i sometimes have issues and many times it just causes the base to get dislodged as the next adjacent line comes in contact w/ that first skewed line. I am using a Maker Select 3D and currently using Cura if that matters. I did create a few things with tinkercad as well so perhaps it doesn't add those lines to the gcode?


Thanks much guys.
