Prime pillars let you make sure that each nozzle is ready to print when you swap between HotEnds. Each time the nozzles prime they build a pillar next to your print.
If your printer doesn’t switch HotEnds on a particular layer, it will still print a layer of the prime pillar to keep it sturdy and ready for the next time there is a tool change.
This lets you adjust the size of the prime pilar. This uses G2 commands that not all firmwares support to draw arcs. This will not show on almost all G code editors with the exception of: https://ncviewer.com/
Higher numbers increase the size of each prime pillar, taking more time and filament to produce. Raise the size of the pillar if your nozzle isn’t getting primed before starting the next layer of printing, and is instead leaving holes in the perimeters of your prints. You should also increase the size of the prime pillar if you’re switching filaments in the same nozzle and the transition from one color or material is happening inside your print instead of while printing your prime pillar.
Lower numbers decrease the size of each prime pillar, saving time and filament but potentially losing stability. Making your prime pilar too small could make it topple over if it doesn’t stick well enough to the build plate. Small prime pillars will extrude less filament, so make sure that you’re still printing enough to prime your nozzle (or transition between colors/materials if you have a 2-in-1-out system).
Skirts are also used to prime your nozzle, and let you test your bed adhesion at the same time.
This controls the how wide your skirt will be. Wider skirts give you more time to prep for your print by leveling your build plate (if necessary).
Lower numbers will generate thinner skirts, and save time and materials.
Higher numbers will generate thicker skirts and give you more time time to prep before starting your model.
