Cura was also the first one i used, but it was a creality branded shitshow of a program. So i found orca slightly after that and now use it ever since. I love the inbuilt filament calibration tools and especially, that i can control my printer directly from the slicer, to e. G. stop a job i sent too hastily or something.

Yes, i tried the flatpak too, but it doesn’t do well with hardware accerlation and nvidia gpu. Also i think there was an issue with localization to german.

IMHO the best slicer is orcaslicer, which works fine on Ubuntu as an appimage. On other distros i used distrobox to create an ubuntu box and then start the appimage.
