Okay - Prisa Slicer 2.9.2 doesn't have CoreOne profile?  

RE: Okay - Prisa Slicer 2.9.2 doesn't have CoreOne profile?

Launch Prusaslicer, navigate to Configuration->Configuration Wizard.  From the tool select Prusa Research, find the Core One category (should be at the top) and select the printer configurations that you want (nozzle size, MMU, No MMU, etc).  If these are the only changes you want to make click finish otherwise select a different category and when you are all done click finish.  It is not necessary to run through the entire wizard once you have installed Prusaslicer one time.

Steve

RE:

Sorry - no joy; no CoreOne listed. Period. End of Story. lol.

Finally got the profile -- seems I had to accept a configuration update to ALL profiles (destructive of modified profiles, so something I generally avoid). Why force this when all I want is the new printer... lol.

When you run the configuration wizard it only installs the profiles you need which in this case (I suppose) is only the C1 and whatever nozzles and filaments you plan to work with. How would it know a priori which printer you want?

You are failing to understand the issue. Think onions with layers upon layers of things you need for this to work.  In my case, opening Slicer did NOT present me with any options to install any of the CoreOne bits -- they didn't exist in my base configuration profiles even though I had 2.92 installed.

I had to go back and allow the config wizard or whatever part I was allowing to run -- config update ? -- which overwrites all of the factory configs, even if modified, and this apparently also added in the new Prusa printer list; at which point I could select the latest printers. It was a rather obtuse requirement - especially since I had run the config wizard several times already. Its an old complaint, mixing printer profiles with filament profiles.

RE:

I’m not sure what the issue is then… PrusaSlicer should prompt you at startup to install the new configuration whenever it is available. Also, you cannot modify the default configurations anyway, you have to create a copy which gets saved as a user profile. When I converted my MK4S to Core One, I simply went to the Configuration Wizard on 2.9.2 and selected the CoreOne. Over subsequent configuration updates, my custom configurations were preserved. 

RE:

@hyiger almost correct.  Yes you can not modify the default configurations.  However even your saved copies can be silently changed on you when Prusa do a configuration update.  

It has to do with profile inheritance.  So say you have a specific filament profile for PLA X.  That will be based on the Generic PLA profile.  So you change something about PLA X and you now have your Own PLA X - copy.  If Prusa update the Generic PLA profile then anything based on it will be altered, so that's PLA X and your PLA X- copy.  The only thing your copy contains is the contents you have changed.  Same as the PLA X profile  will only contain what's different to the Generic PLA profile.  These dependencies can actually also be multiple levels deep.

If you want to stop this you have to use the Detach from System Preset Button and then save it as a copy.  

This applies to ALL profile types, not just filaments.  If you truly want a totally independent set of profiles you must do this for all of the ones you make copies of.  That way if Prusa make changes they wont be pushed to yours.  Of course the side effect is that if you want any changes you have to manually make them and save.  

All my profiles are like this as I don't want anyone making any changes to them but me, even Prusa.
