Normalement tu peux juste drop ton UFP dans CURA mais tu n'auras plus aucun contrôle dessus, quasi rien d'exploitable, c'est le 3MF qui embarque toute l'info : la 3D, les settings etc.
 
Avec un peu de chance, tu n'as pas touché à CURA depuis, il devrait avoir gardé tes settings : plus qu'à drop ton STL à nouveau dans la scène et ajuster l'échelle 😉

Yeah, my UMS5 was also completely off regarding X/Y alignment... You'll need to re-align the axis, using a printed tool that is not included. It's not difficult, just need to be patient enough and the access to the screws are not the most confortable.

Now, UltiMaker, it's quite a shame that you do not include theses tool in the box. Like, really. And what is even more a shame is that some of your machine arrive completely off, while it's sold as the Plug and Play for professionnal with no tuning, no hassle, etc. Please, you need some more Qcheck, and you could (should) clearly deliver the printer with a proof of performance printed right on the bed, just like Prusa, that would actually show about Axis alignement for instance.
 
Sure, carrier issue is a thing, but you're the one to handle this and find a way to avoid such mis-alignement.
