Yeah. You always need to remove nozzles while warm. The bambu nozzles arent replacable either. its a heat break/nozzle assembly also.
What maintenance are you talking about? Like cleaning rods n whatnot? the bambus need it also. more often even. Bambu is #1(in this price range for a prebuilt non kit) but if everybody jumps on the fan boy bandwagon, bambu will be the only option left soon. Im american, so enjoy options.
I get that alot of prusa and anker design is old but so is the bambu design. Everything thats being done in this price range has already been done. Lidar is the one standout but alot of people stop usingbit right away because of the added time of startup.
