This has happened to me multiple times, I load a model print it, clear print bed select new model hit print and it prints the previous model.
The only sure fire way that prevents this is to clear the print bed, close Cura, open Cura and then load the new model.
I have searched far and wide to see if anyone else has this same problem but I have not found one instance.
Cura LULZBOT Edition 21.04 printing via USB
I’m a newb so if i’m screwing something up please let me know in a kind way…
