How does one do this? I have google drive. I've located the Prusa folder in my app data folder, but how can I sync this across machines?

Here's how I do it using OneDrive. Google Drive, Dropbox, local NAS, should work the same.

• Go to Prusaslicer's Help menu and select Show Configuration Folder
•  Go up one level and note the location/path name of the folder. It's usually /Users/username/Library/Application Support/PrusaSlicer (alphas and betas have different names). On Windows, it would look like C:/Users/username/AppData/Roaming/PrusaSlicer or similar.
• Create a backup copy, just in case.
• Copy the configuration folder to your network drive and delete the original. Note the new pathname, in my case /Users/username/OneDrive/3D Printing/Software/PrusaSlicer/PrusaSlicer
• Open a terminal window.
• Create a symlink on each computer on which you want to sync it:

ln -s /Users/username/OneDrive/3D Printing/Software/PrusaSlicer/PrusaSlicer /Users/username/Library/Application Support/PrusaSlicer

What all this does is create a "master copy" of the config folder on a network drive (OneDrive/Gooogle drive/Dropbox handle the syncing of that drive across machines in the background). The symlink creates a pointer to that folder in the location PrusaSlicer looks for the config folder.

If you don't know how to setup sync then an simple symlink to a NAS on your local network is actually better if you're not going to work off site.

Cheerio,

It's already possible, just sync the ~/.config/PrusaSlicer folder on each machine to one one the cloud.

That's what I do. I use symlinks to sync the config directory to a OneDrive folder. I've also used iCloud. And I'm sure Dropbox would work as well. 

Having said that, I totally support the OP's suggestion. Makes a lot of sense to me to have a native sync solution rather than relying on an approach that requires a bit of advanced understanding of technology. 

Cheerio,

Cheers :)
