I'm also using the Linux Appimage. Extensions are 3rd party add-ons. Setting Guide Extension creates a pop-up dialog you can call up for any setting with a short paragraph of explanation and maybe a diagram. It is basically an online reference manual. If you use OpenSCAN, there is an OpenSCAD extension that allows Cura to directly open OpenScan files without having to convert them to STL. There might (maybe) be some advantage to skipping the STL file format. Another is "arcwelder" which allows Cura to generate code for arc, rather then the million tiny line segments. Notice the arc print with less noise. It only works with printers that support the M code for "arc" most do. > > > If so, I > > think it is pretty clear.
