How difficult would it be to increase the build plate size of a 0.2R1 from 120 to something larger like 200mm? I would be OK keeping the 120mm Z-axis print height

    For ABS/ASA, a V0 will likely be less frustrating. Larger ASA/ABS prints in a big printer invite warping for two main reasons. The first is just basic physics, larger parts have more material for tension to build in so they’ll be more likely to warp. The second is chamber temperature. By their nature, smaller printers will have smaller enclosures with less surface area, which means you’ll be able to get it toasty in there with less effort/modification. My 350 with just the filter installed and the stock 3mm acrylic panels struggles to get much above 40-45° C in my 65° F basement - even after soaking for two hours. I’m aiming to bump my chamber temp another 20° C to reduce/eliminate warping, but that’s likely going to require a decent amount of modification.

      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
