I've never had a problem designing parts on Fusion 360, clicking on "3d Print", selecting the part, clicking "Cura" as the print utility and hitting "OK". Cura then pops up and I slice it and save it on my Ultimaker SD for printing. Now Cura won't even pop up after selecting the part and clicking "OK" like it always did before. I've uninstalled Cura and reinstalled it twice with no luck. I even upgraded to 4.8 and have the latest Fusion 360 version. Any suggestions? Jim
