I use S3D for a couple of printers. It has been pretty much flawless up until recently. Now when I change profiles to one that is attached to a different printer, it doesn't always change the settings to that printer. It seems to load all the material settings, etc, but keeps things like printer size and hotbed type of the previous printer. It caused some issues when I didn't notice what was happening. The other odd thing I have noticed is that if I go to add a new printer with the configuration wizard, there have been a number of times that it could find the selected profile - "unable to retrieve available profiles from Server. ( i.e. Ender 3 Pro ) This happens in Windows, Mac and Linux.
I had migrated my Windows install from another system but have since uninstalled completely, reinstalled, and recreated or imported previously saved profiles.Still have odd time when it does this and I have to reenter the proper printer config.
Not sure how to fix this if completely uninstalling didn't seem to work.
