I understand the purpose of printing with a skirt (or at least, I think I do): it gets the filament warmed up and flowing properly, in order to avoid extrusion problems while starting to print the first layer. (Perhaps it has other benefits as well? If so, I'd be interested to know what they are.)
However, what's not clear to me is why skirts are set up in exactly the way they are. In particular:
Why is the skirt drawn around the whole of the outside of the print, at a roughly constant distance from it, instead of (for example) just going round in a small circle in one corner of the print bed?
Why does a print with a larger first layer need a skirt that uses more material?
I ask partly out of curiosity, but also partly because I'm printing several small but awkwardly shaped parts, and using a skirt reduces the usable area of the build plate. If the skirt could just be put in one corner instead of going all the way around the edge I would be able to fit more parts on the build plate. This leads me to my final question:
- In Cura, can I change the layout of the skirt, so that it gets drawn in a convenient part of the build platform, instead of going all the way around the edge of the print?
