That will be a shitty day. But the alternative is that they don't sell replacement parts at all. To be fair we don't even know how they treat discontinued products as all their printers are still in production.
Still my point stands, Bambu printers simply just work, I took my 15-20 minutes to set up and it did run flawlessly since then with only the maintenance the printer asks me to do. I can understand why people like that. This would be possible by opensourcing everything but somehow except for Prusa there is noone else who strikes that balance between ease of use and openness.
That's the third option, I was just saying that at least they do sell replacement parts which today is not always the case for many companies.
