Sorry to be the bearer of bad news.....but you have discovered S3D's worst kept secret!! The printer profiles are stored away somewhere within the Windows registry....in a way that is not known by very many!
And, iin fact, this is one of the most griped about things in the software. If you don't save your precious profiles in one of a few ways....then should your Windows environment go ZAP.....so do your profiles!!
So.….you'll have to import into the new S3D environment all the profiles you have exported. That is ….if you exported them in the first place!
Okay.....you'll be able to reassemble your set of profiles by recovering the profiles from all of your factory files. That is....if you ever saved anything to factory files.
Final chance.....you can read the profile settings from the comments in the GCode files you have created.
Failing any of these......a phrase with the words "drawing board" springs to mind!
That is unles you're feeling exceptionally brave....read this! viewtopic.php?f=8&t=2821&p=32397&hilit=registry#p32397
