So I've bought a Bambu Labs P1S Combo - half of which arrived this morning
I know nothing about the Cetus (except it's a bed-slinger, IIRC, not a core-XY), so the Bambu is going to prove to be a world apart from it. In a good way.
IIRC, the "Combo" is shipped with the AMS unit inside the printer, so it's probably all arrived, not just half of it...
I struggled to justify the price of a Bambu (plus they'd just recently announced that they were going closed-shop with their software, and that if you wanted to use all the features of the printer you had to use their online services), so I went for a Qidi Plus 4 instead. Superb machine, and now I have their equivalent of an AMS, I can do most things a Bambu can do - also slightly bigger, although the Qidi experience isn't as polished as the Bambu one...

It replaced an Ender 3, and it's just so much better I actually threw the Ender away!
