Skirts
A Skirt is an outline the surrounds your part but does not touch the part. The skirt is extruded on the print bed before starting to print your model. Skirts serve a useful purpose because they help prime your extruder and establish a smooth flow of filament. Observing your skirt also allows you to detect any printing or leveling errors before you start printing your actual model. A Skirt is typically offset 3-4mm from the part. It may have 1-2 layers and 1-2 outlines. Note: If you have enabled Supports under your model, the outline of your skirt may be extended to surround the supports.
