Apart from blow up printers, the one scariest thing for me about a slicer is losing settings. You spend hours getting your printer dialed in, specific profiles per material and then…
You update your slicer software and it all goes away. I have now learned Cura does this. And does this a lot. Forum posts abound about it. Friends recommend I switch to Prusa because it happened to them. Unfortunately too late for me to write down my old settings, and they’re apparently not in the ~/.config/cura folder anymore. Nice.
I’ve never had issues with Cura losing my stuff (been using it with an Ender 3 since… 2019 I think) but the backup plugin is connected with your account. It’s a wonderful thing! New computer? Login, restore backup, everything is like you left it.
I do make sure to use it before any update because I have seen the same kind of posts as you have.
