RE: Prusa Core One - Intial thoughts......
I just don't see the economics of the upgrade to the Core One, unless you have to have one platform for some reason. My Mk3S/MMU2 is going to get de-MMU'd and the MMU unit getting the full "Office Space printer farwell" and going to become a REVO mod, like my 2x Minis. My Mk4 will become an S as soon as I get some time to put the kit on. Toying with a Core One for at work in our lab, maybe with an MMU3. A camera would allow me to remotely print stuff. But I'm not sure what "Ships January" means for an order I place now. MIght just go for a local printer with an AMS unit.
The Core One is, to me, the most compelling Prusa printer, ever. I've been on day/hour 1 order for every prusa since the Mk3. I've passed on this one. Just tired of the "manana, manana" when it comes to new models. That and 5 Prusas already, but I do often have four running at a time... It is starting to be a space issue.
I have two MK3S and 3 MK4S. I am not sure what to do as an upgrade path. I will probably upgrade the Mk3S to 4S and the 4Ss to Core One.
I have not upgraded yet, either. I am contemplating a Core One assembled and then upgrading but I want to see the shipping cost of the kit.

RE: Prusa Core One - Intial thoughts......
With the recent changes announced by BambuLab (breaking compatibility with 3rd party hardware and slicers and locking down their firmware), many people are going to be thinking "Fine, I'll pay the premium for a CORE One to get a product I can rely on for the long term."
All Prusa has to do is overcome his/their tendency to not be detailed when communicating shipping timelines for pre-orders, and they'll be back on top in the 3D printing world. They're already almost there.

I gotta think that this new bulletin from Bambu is prompted by a new release about to go live. They aren't standing still. By the time Prusa ships the Core One, the landscape might have changed significantly. Will be interesting to see how they handle the backlash from their new direction.

Bambu Labs is killing itself with locked-in software prusa should grab the opportunity and run with it
RE: Prusa Core One - Intial thoughts......
I am not sure how much back lash there will be. I can't stand the locked in nature, but many consumers could care less.

You're right that many consumers couldn't care less, but the problem for BambuLab is that they've annoyed their most loyal and enthusiastic customers (some of them even describe it as a betrayal). Most of these people are Bambu's biggest brand advocates, and now they will tell friends and relatives to avoid BambuLab and go up market to Prusa or get something cheaper from a company like Creality.
It remains to be seen whether the loss in sales due to negative word of mouth will be offset by future direct marketing, but it seems like a risky strategy for BL given their lack of complete market dominance at this stage.

Apparently that lock is already broken:
be it that the crowd will not care and let father Xi be reported about anything they do with their printer or what happens around their printer.
But let's get back to topic.

RE: Prusa Core One - Intial thoughts......
In the Core One upgrade, I suspect only the MK4 Nextruder will be kept.
I cannot see any other parts that can be transferred.
All of the stepper motors will likely be transferred, in addition to the X-Axis linear rods (likely becoming the Y-Axis in the core one), at least from what I gathered from the various interviews. There'll apparently be a third Z-axis threaded stepper that'll be shipped with the upgrade kit to make the build plate a complete three-point plane. We will also likely transfer over all of the electronics - in other words, most of the 'guts' will be transferred along with some structural elements, almost like the inverse of the MK3S -> MK4 upgrade kit.

I think we'll see a lot more of the MK4S transferred across then we think.
We know for certain that the entire extruder moves across, since it's the same in the Core One just in a slightly different fan/nozzle position/arrangement. The screen, electronics board, print bed, PSU etc are all the same, so they'll all go across. The X and Y axis rods/motors will move across since we retain movement across both axis - just in a different arrangement. And it's also been confirmed the Z axis threaded rods and motors will move across, with an additional being supplied in the conversion kit to make up the third Z axis. In essence, it's really just the same printer overall - it's just the arrangement that's been changed, which is pretty smart of Prusa to be fair. They've made an entirely new product line by re-arranging an existing! lol So most of the 'conversion kit' will consist of the new enclosure.
In essence, once converted, you'll only really be left with the main frame of the MK4s left over......

RE: Prusa Core One - Intial thoughts......
As far as what of the MK4S Nextruder will transfer directly to the CoreONE, (recognizing we don't have the upgrade instructions yet), I would expect most of the printed plastic parts to be replaced going MK4S to CoreONE. I would expect the motor/gearbox, love board, heatsink/frame with integrated loadcell and filament sensor, large blower (and possibly metal bracket) to transfer. From what I see in the announcement videos and blog, the nextruder is on a linear rail so the 3 bearings on the MK4S Nextruder won't transfer. It won't be a drop-in replacement.

Probably. If I were you, I'd wait until the upgrade instructions are available. Then you will see what parts are expected to be re-used from the MK4S. See what is needed that you don't have on your 3.9 and see if you can order the spare parts from the Prusa store. If you come up with a solution, if you are feeling generous open a forum thread here to tell others the results of your homework.

RE: Prusa Core One - Intial thoughts......
Anyone a bit disappointed by the xy build size? I get wanting to maintain backwards compatibility, but wouldn't it have been possible to be compatible with the current plate size AND a new bigger one? I am heavily considering getting this machine and would be coming from a Bambu A1. But I just looked through a lot of my past printing projects and realized that I have used the full 256mm on several projects that I would probably repeat in the future. I've been waiting on the Core One kit so when I realized my dilemma I checked out the XL. It is over 2x the price of the Core One kit with the single toolhead. I know I'm just screaming to the void... but it would have been nice to be able to know I'll be able to print the same things I have been without modifications. Oh well... fingers crossed that the bambupocalypse doesn't happen anytime soon. I don't really want to have two printers. Rambling rant over.

Core One provides an upgrade path for existing owners; hence, attempting to reuse as many MK4S parts as possible. No doubt in my mind there will be another printer released this year using the same shell/footprint only without the recesses. Remove the recesses and it looks like it could be a 270x270x270 chamber and I bet a 2 or 3 head tool changer.

I was kinda hoping for a slightly larger XY size (I almost don't have any use of increased Z). But printer of this size has its own place, not only because of backward compatibility (which I didn't consider that important at first thought, but I realized that I do have many plates in that size and am still buying some) but simply as a compact printer for those that don't need large prints. As others are guessing, there will probably be a new printer between Core One and XL in future.
RE: Prusa Core One - Intial thoughts......
Removing the recesses won’t increase the print volume—the x/y dimensions are determined by the size of the scaffold that contains the print head/belts/motors. If they come out with a larger CORE printer it will have to be significantly different than the CORE One.
RE: Prusa Core One - Intial thoughts......
I get wanting to keep backwards compatibility, but if it was slightly bigger, then there could be a sliding piece or something to reduce the size to the old plate. I'm just not sure I buy that old build plate compatibility is a real issue. I assume since the toolhead has to move in the xy direction now, it would mean the mk4 parts need replacing anyways right? Once the printer is out and in people's hands, I guess we'll get a better idea as to why the decision was made.

RE: Prusa Core One - Intial thoughts......

Nah, I thought the same thing when I bought the XL, that I needed a larger build volume. Now a year later the reality is I've used that large volume only a handful of times. I use my MK4 way more often which means the Core One is the perfect side-grade for that printer.
I'm not saying the large volume is pointless. When you need it, nothing else will do. But I hardly ever need it. However I bet they'll announce a Core One Plus or Core One Max in 12-18 months with 300x300x300 build volume. The demand for large volume printers is clearly there.
RE: Prusa Core One - Intial thoughts......
Something between Core1 and XL with 2 or 3 heads would be interesting provided it can seamlessly print VariShore TPU alongside PETG or PC. Thus filament paths would need to be straight and simple. That is my concern about the Core1 with its complicated flat-hinged horizontal and then sharp bent down filament path, that you cannot easily feed flex material in. I understand XL owners bypass the (more simple) feed system and feed flex filament from a spool hanging above the printer.
