I found some useful info on the configuration structure in PrusaSlicer. Here's a quick description:
https://www.reddit.com/r/prusa3d/commen ... slicer_20/
There are three configurations in PS:
Printer Settings: This contains info about your hardware, but it also overlaps a bit with other settings in that it contains default settings for things like extruder & bed temperature.
Filament Settings: This contains info for a specific filament, and has some redundant entries for things like the temperature settings. The settings in the filament config will override the printer default settings. This is where you can also set things like cooling, extrusion multiplier, retraction, etc.
Print Settings: This is where you specify a lot of print details specific to the model you are printing. It includes info on layers, infil, skirts, speeds, etc. The terminology they use is different from S3D. For example, they talk about vertical and horizontal shells instead of perimeters. They mention having different Print configs for different types of models. Unless the smarts under the hood are WAY better than S3D, I suspect I will have Print settings for almost every different model I work with.
As best I can tell, the original configuration from airscapes contains just a filament settings configuration (at least that's how it shows up in my program). I have now created a Printer config, a Filament config for eSun PLA+, and I'm working on a basic Print config. Once I get a full set saved, I'll try to export a Configuration Bundle file and make it available. I think exporting a Config alone just saves the current three settings in use. In fact, if you import them, I'm not even sure if it loads them automatically. It will add them to the list of available profiles, but you may have to select them to put them into play.
