Prusa Slicer 2.2.0 System Presets different for MMU2 and Single

Something has happened to the systems presets as loaded for the MMU2S and the Sible printer profiles. For the MMU2 set all  presets below 0.15 have disappeared. Please see screen shots

RE: Prusa Slicer 2.2.0 System Presets different for MMU2 and Single

That's correct.  The single has more available presets than the MMU.

All the prusa preset profiles, filaments and print profiles use a inheritance scheme.  This scheme determines what is compatible with what.  That's why for example filaments installed from the list during the wizard will be visible to a MK3 printer but not for example a Ender 3 or a custom printer (beyond the basics).  The same applies to print profiles too.  This is because Prusa believe those combinations are not compatible.  This new scheme was introduced in version 2.2.0.

You will notice that the list of available filaments is also different when you have MMU2 selected.

You have to create your own profiles.  Alternatively you can select the single where the profile you want is available, save a copy of the profile and then under the Dependencies section use the 'detach from system preset' button to break the chain.  You can then save it again with the detached status and it should then be available to all your printer profiles.

One other 'feature' of the inheritance scheme is that any time you update your profiles from the web then Prusa can make changes to the base settings, these then ripple down to any profile that is based/inherits from those so you can find even your custom profiles that arent detached changed.  Its a nice system for those that don't have a lot of experience and want to rely on Prusa settings.  As these are generally decent anyway its not a bad thing.  However if you know what you like and want to make sure things don't unexpectedly change on you then take control of your own settings and profiles.

I always assumed that at the finer resolutions, filament changes, with associated wiping, were impractical and discouraged.
