If you’re printing PLA then 80°C bed temp is way too hot and probably contributing to warping, lower the temp to 60°C or so. The filament roll should have suggested temperatures labeled on it somewhere.

Yes! Access to my files via web browser from any machine without having to install software was what initially drew me in, but it’s replaced almost all the CAD software I’ve tried including Fusion260 and Freecad.

I’ve moved away from free personal Fusion360 to OnShape and it suits my needs just fine. The free tier makes all my models public but I don’t mind, and it runs much more smoothly in my browser than Fusion ever did on my desktop.
