Yeah - we have 4 printers at the moment, one of them a Prusa MK3S+ & it has been maintenance free so far.

The other printers are basically custom designs by this point & you need to fix things sometimes - like recently erosion of the filament eationg away enough of the idler arm to slip from the forwarding wheel. But I don't mind, because I can easily fix all of that with either 3D printed bits or easily & cheaply available common parts.

I don't mind because I know I can fix ynathing on those printers! No issues like with 2D printers with closed firmware that worksa against you to print secret dots, only accepts locked down blessed overpriced consumables & fails to print if only one color runs low. Not to mention the bloody thing is basically unfixable & any drivers already suck + they will drop support on a whim anyway.

Seriously, would rather fix the 3D printer after every print than to deal with the level of bulshit common on 2D printers - and ot seems to me that Bambu is trying to achieve exactly that!
