Never heard of Qidi, thanks for sharing that! Bambu concerns me, frankly, from the "too good to be true in capitalism-land" standpoint.
They're obviously pretty quality built and do a great job off the shelf, but the closed source software is iffy to me too. I think some are suspicious they just don't want to reveal they're basically running tweaked Klipper lol. I'm lured by that temptation of not having to tweak and fiddle for weekends prospect too, but if I can't touch it at all or know how it works, my Ender3v2 still seems more appealing!
I'm concerned if other companies don't seriously step up their game, Bambu will reach market saturation and then go for the" enshittification rug pulling to impress investors" special.
Anyway don't want to be too negative, clearly people are enjoying those machines. But the maker community definitely needs to be ready to raise a riot if Bambu starts taking notes from HP / Apple / John Deere. :)
