Hmm, that's a good point I didn't consider. I didn't think the larger printers were struggling that much maintaining higher chamber temps.
It's a lot of volume and a lot more area for loses. You're only really heating the chamber with a what a 750 W heater to heat the build plate, by default you're only getting natural convection and radiation to heat the interior, bed fans help and so does something that recirculates the air in the chamber. I generally don't have issues with abs on my 350 mm v2 but larger, less substantial prints will have issues, I'm dropping some extra bed fans in when I do some upgrades this week which should help me get higher temps
