This Cura plug-in provides additional explanations with pictures and animations for every Cura settings. It's based on the excelent Plugin SettingsGuide developed by Ghostkeeper. But I have integrated somme additionnal articles relative to the Cura Master Release.
You can install this plug-in From source: Download the latest source code from Github. In Cura, click on "Help", "Show configuration folder". Navigate to the "plugins" subfolder and unpack the .zip file from Github there. Rename the folder to "CuraMasterSettings" (removing any suffix that Github added such as "-master" or "-main"). Restart Cura.
To use this plug-in, right click on a setting you'd like to know more about. Then click "Settings Guide".
Alternatively, click on "Extensions" in the application menu, then click on "Settings Guide"
