I created a model in TinkerCad. Exported the .stl file. When selected in Cura the preview window (before I opened it) had the model on its side and not vertical as desired. Opened the model in Cura, it was upside down. Rotated it to vertical. Started to print it on my Ender 3 V2 printer, and it started to print it on its side. How can I get it to Cura to print it vertically as desired?
after rotating the model in Cura did you reslice it?
?
