Yes, it’s Option as well. Only extend the Height.

In CoreXY you’re limited by the length of your belts. Belts have non-negligible flex at the lengths you’re talking about. You need wider, stiffer belts to go longer, and that means bigger extrusions and bigger frames. The ratrig vcore can do 0.5m^3 because it’s using bigger belts and beefier extrusions. You really don’t want a Voron bigger than 350mm^3 because you run into issues.
I’ve got a Voron 2.4r2 in 350mm^3. It takes an hour of warm up and preheating to get stable too a point where I can print. That makes the 10 minutes for my x1C look like a walk in the park. Honestly, it is super cool and I built it myself, but I only use it for the occasional larger model or for full plates of parts at once. For most printing, the X1C gets the call because I can keep different types and colors of filament in the AMS. For most quick prototypes, I typically use my Voron 0.1. It has the smallest build area but for things that fit it’s a rocket ship.
There is a cool factor in having a larger printer, but there’s also a lot of technical challenges as well. People have bigger eyes than stomachs, and if you really do need that build volume in a CoreXY, I’d seriously recommend looking at the RatRig.

Yeah you know Creality slapped that ■■■■ together and it’s not going to be nearly as reliable as my X1C, plus they have no color ability.
Yea he ain’t wrong and I too would buy a bigger X1 or X2

I just bought a Neptune 3 Max as my second printer because I need to print some single-piece items that are 320 MM on one side. I would have bought a Bambu Carbon XXL in a heartbeat.

In my experience Creality products are pretty good quality. I’ve had a couple and they’ve always been reliable …for me anyways.
Although I think they were in a hurry to get to market, I do think they did quite a bit of research and development. The final product looks pretty polished to me. The fact that the X one came out almost a year ago tells me that they’ve been working on this for a year.
So I don’t think they “slapped it together”, and multicolour is coming soon to the Creality, CoreXY lineup. Although it’s not officially announced, there are some hints on the website.
That being said, I would still like to see a larger, build volume from Bambu. I would be more interested in purchasing a larger machine here then I would from Creality.

We are an engineering R&D business. We bought several FDM machines since 2019 looking for industrial filament use, >400mm diameter x 500 high envelope, and we were prepared to spend significant money for a machine with quality engineering and a promoter able to offer support. We failed to locate anything apart from Prusa’s and Stratasys machines that were close to reliable and did not require expertise to be developed by the user.
After giving up on a 500 cubed Ratrig custom build (with heated enclosure, braced structural frame, tubular anodised gantry, Clipper OS and other additions) due to lack of time, we bought a Bambu recently because of the DJI engineering connection. Exactly what we needed - a fully-engineered machine (not a project), and proper process support.
I think the 3D printing world can be segmented into ‘fiddlers’ and people whose time has commercial value. We need reliable in-house printing, and we need bigger envelope than the X1C offers. Anyone who thinks that doubling the linear dimensions of a printer is easy, doesn’t understand FDM printer engineering and doesn’t understand the needs of users like ours. When Bambu bring out something a bit bigger, in the X1 line, we need it to plug and play. The fiddlers wont mind whether it works with minimal learning curve, but users like us will!

‘fiddlers’ - you are damn right about that.
I am surprised at how this community is “used” to fiddling - almost to the point that if printer doesn’t need fiddling, then there is something wrong with it.
If you ask me, even Bambu has too much fiddling needed. It works okay for PLA, but if you need to print anything else at same quality, you have to fiddle. And even if it means only changing bed temperature, it is still fiddling. Someone who purchases 3D printer because he/she needs to print some part(s) does not want to fiddle. It may be easy for fiddlers to know what to do if the print does not stick to the bed, but for beginner it means learning - reading stuff, watching videos etc…
Compare 3D printers to classic paper printers. How many people own classic paper printer? How many actually know how do they work? How many fiddle with settings? Classic printers are something you buy and you just expect them to work. No fiddling, just insert paper and press print. When 3D printers become like that, then we will see widespread adoption, until then, it will be limited to mostly fiddlers. Bambulab is probably the only company that knows that.
When I started with 3D printing a month ago, I was surprised that people still put files on SD cards and “carry” them over to printers. The first printer I bought (Kobra Max) actually has this the “preferred” way of doing it. That is 90’ tech. And when Bambulab comes out with printer that allows you to print without SD cards, half of fiddlers go “woah, this is so cool!” and half of them scream “privacy, privacy, privacy!”.
Looking from the printer manufacturers point of view - I am simply astounded that using outdated slow microcontrollers, SD cards etc… is still a norm in 2023. And why is it so? Hm…

I remember fiddling with my IBM PC for pretty much the entirety of the 1980’s.

I’m a person who believes anything can be done. If you want to talk about the DJI connection,
… think back to 10 years ago and imagine a world where somebody told you that you could have a flying 4K camera. You would’ve laughed at them.
Innovation is constant and continuous. I have a positive outlook.
Given enough time, effort, and money, anything can be built. In fact…I am sure Bambu is currently working on the next generation line of products, and I’ll bet my hat that one of them will be a larger build volume.
You know, we are not reinventing the wheel here. They’re all already large Core XY machines in existence and they work just fine.
There are already machines out there that are very close and build volume to what I am suggesting.
Fusion3 EDGE 3D Printer has a build volume of 14.5″x14.5″x13.5″ (367x367x342mm) its a commercial machine and is pretty much plug and play.
Not far off from 450…

That would mean you are not allowed to use 3rd party filaments anymore. It would require to be a complete closed system. I hope it does not come that far in the consumer 3d printing world. Same as with normal printers, we would be forced to pay a heavy premium for ink/filament.
But I do like a lot that the BL printers are very much plug and play and work good enough out of the box, but I do not see any system in the near future that would get rid of slicer settings. It would require a crystal ball then to know what the user wants.
Would not require a closed system at all.

Your sarcasm just proved my point 
Read my comment after 10-20 years when 3D printers perhaps do become mainstream. Everything will be automatic and terms “retraction” and “Z offset” will be known only to manufacturers, not end users.

It will require a closed system, as filaments are way too different to just print “out of the box”. Ink jet printers are pretty much a closed system as well, not only for reliability (which plays a part still) but also for financial aspects.
Ink jet printing is just a 2d layer with a single well defined printing material. They worked “out of the box” from the very beginning, and even their predecessors worked simply out of the box. 3d printing is quite a different beast, and unless you shrink down the variables a LOT, you will not get an easy out of the box experience in any kind of near future. And the two major possibility to reduce variables is material and shape of objects supported…and guess what manufacturers will pick?
Sure, most likely manufacturers of hardware will also provide their own filaments that work the best with their machines. Just like paper printers do it today. And people will pay some % extra premium price, just for ease of use. Time is money. Not having to deal several hours or days to fine tune certain profile for filament has its value. What would you prefer to buy, a proprietary filament that works out of the box for a machine for higher price or a filament that you need to fiddle with for days, but is cheaper? Not to mention all the know-how knowledge you need to have before even being able to do the tuning.
I bought various Bambu filaments with hopes that these would work out of the box with their system profiles. It works great for PLA and Support-W, unfortunately not so good for PETG-CF. The rest I haven’t tested yet. Because of that, I am a bit disappointed. But I am looking forward very much to the time when every single Bambu filament is optimally tuned with system profiles so that I don’t have to fiddle with it and just focus on end product.
Paper printers worked out of the box, because the technology is not so complicated. 3D printing has a lot more variables to tune in. But nowadays with the rise of AI, who says that technology cannot be perfected to the point of full ease of use. We are slowly going there - for example - spaghetti detection feature is one of many that are going to be needed for full automatisation.
There are endless possibilities - just one that comes to my mind is real time scanning of printed object and comparing it to the virtual 3D model. Adjusting all important variables on the fly when the print is on going and adjusting them to improve the print. Current printing technology is a “blind artist”, going on and on without any feedback of “how it is going on so far”. This paradigm needs to be changed first, so that printing is getting real time feedback during printing.

I’m glad someone caught that.
But yes, one day these printers will be automatic just like a paper printer.
I don’t know if anyone remembers how tough it was just 30 years ago to get good quality color prints.
The printer’s for sure where not as friendly as they are today. I’m specifically talking about the plotters and other stuff used in graphic design. Some of those things could drive you insane, sane, and back again.
Try a 1980s plotter. Drivers will be an issue but not the first and only issue.
