RE: Prusa Core One - Intial thoughts......
It’s not exactly the same.
Apple operates with a predictable roadmap—for example, every September/October, they announce a new line of iPhones. The same applies to iPads and MacBooks, with updates typically released every 12 to 18 months.
Prusa, on the other hand, had a 4-year gap between the release of the Prusa i3 MK3S and the Prusa MK4 (excluding the MK3S+, which was merely a minor update). This prolonged gap gave competitors like Bambu Labs an opportunity to enter the market unchallenged.
Now, within just a few months, we’ve seen the release of the MK4S and the announcement of the Prusa CORE One—just in time for the holiday season, potentially disrupting end-of-year sales. On top of that, every new product order requires a months-long wait, leading to the conclusion that Prusa’s business strategy is, at best, bizarre.
What keeps them afloat is the fact that they produce excellent products, enjoy a stellar reputation, and have a loyal, dedicated customer base.
To be fair, you've raised some good points there.... 😉
What we also need to remember is that te Core One is not intended to replace the MK4s - the MK4s will still be available and will still be for sale alongside the Core One (whether people decide to buy it or not is another matter) so it's more an expansion of the product range rather than only an upgrade to the one product line.....(even though we all know we're gonna upgrade! lol)

RE: Prusa Core One - Intial thoughts......
I am curious about how the "Active Temperature Control" works. It is mentioned in a couple places in the video.
The "vent" on top is obviously a MANUAL operation (i.e., manually engage when printing PLA and maybe PETG). But how is the desired temperature (to control the fans) set? It would be nice if it was via Gcode, but that would mean controlling the fans (or sending the target temp, perhaps via I2C, to some other module that monitors temp and controls the fans). But the I2C connection is needed for the HackerBoard, which is separately mentioned as still being an option.
Has anyone spotted anything in the videos or announcement post that tells how the desired chamber temp is SET for each print?
Maybe something can be done with a servo and the optional hackerboard to auto open/close these vents. I don't think it will take a long time before the community finds a way to automate this.
RE:
More likely turn an extractor fan on and off to remove excess heat as a fan would be both cheaper and more efficient than a servo controled ventilation slap

That will be already the case. They said the chamber is actively controlled by the fans. But the vents probably need to be opened to increase airflow when printing PLA.
RE: Prusa Core One - Intial thoughts......
What I seem to understand from the images and from what Joseph says about the printer, is that the hole for the filament spool on the right (viewing the printer from the front) is fixed. That is, it cannot be placed on the left. It's a shame that they have thought that the door can open in both directions, depending on where the user works best, and they don't think that the placement of the filament spool should also have the same philosophy.
Sorry for my poor English. I try to do my best.
RE: Prusa Core One - Intial thoughts......
Does anyone recognize the Drybox shown at 3:19 in the release video? Wondering if that is some existing design, or something Prusa designed internally. Hard to see since it is black, on a black background, and I can't tell if it is 3d-printed or molded.

It's probably worth considering that they likely would have preferred to make the feed reversible also, but in order to do that they would have make the wire/filament chain that feeds Nextruder also be reversible, which would then require either providing a long option of the ribbons involved, or routing the wire loop to the center of the machine and redesigning the whole wire chain. I agree that it would be nice if everything was reversible, but designing things will always entail some compromise. The other alternative is to do what all of the other companies are currently doing and not offer a reversible door. 🤷♂️
When I eventually convert mine, I'll probably install my door with the hinges on the right side because of how it will sit on my workbench, but thankfully I'll still have access to the right side for easy loading/unloading.
There is still quite a bit we don't know about this printer, that will be revealed once units start shipping.

RE: Prusa Core One - Intial thoughts......
So my latest thought is I want the Core One. The Core One would be my everyday, reliable printer, and my MMU3 would move to that. But instead of selling or upgrading my MK4S, I think I want to keep it as a tinker/experimental printer. Right now my thoughts are either build my own frame and turn it into a large object printer, or make it a dual head (shared axis) printer. Or both. Whatever the case, have a second printer I can feel free to mod to my heart's desire while not worrying if it's not available to print for weeks or months.
RE: Prusa Core One - Intial thoughts......
It's really not that much more, X-Y speaking, than the Mk3 series.
I was surpriced by the tiny print area concidering Bambulab being a real competitor 🤔
Even though I`m a huge Prusa fan I think I`m gonna hold my horses a bit on this one. It`s tempting, but I gotta stay strong now 😂😂
RE:
I don't think it would be a problem to direct the wiring and the filament tube to the left side since they are flexible elements. Fitting the nextruder should not represent any more of a problem than making reversible hinges can pose. More complicated is the solution they have given to the XL, allowing it to simultaneously incorporate the spools on both sides of the box. I think the problem is more one of size: the heated bed is not positioned in the exact center of the box, making the two spaces where the filament spool is placed equally wide would make the printer grow about two more centimeters on the X axis.
It would not have been very good for the size to grow considering that the X1C is quite smaller in all axes and yet has a larger printing area.

At some point during the presentation they indicate that it is an accessory that they will present soon.

RE: Prusa Core One - Intial thoughts......
The same X-Y surface allows users to continue taking advantage of the steel sheets they already have and facilitates the MK4s -> Core One conversion kit.
It's really not that much more, X-Y speaking, than the Mk3 series.

RE: Prusa Core One - Intial thoughts......
I think the Core One is mainly to provide an upgrade path to the latest options for previous owners. I bet there will be a new printer later next year that is their mainstream flagship CoreXY printer. I’m guessing features like:
- 270 x 270 x 270 volume (3x3 9cm tiles instead of 4x4 in XL)
- Enclosed chamber
- Dual spool holders, side mount
- Two head tool changer
- Hardened nozzle (default)
This is what I expected from Prusa's new coreXY printer. I guess they do plan (if not already working on) more printers in the CORE series.
CORE One definitely has its place, if you don't need larger print volume, and the compatibility with old build plates is very convenient. But the full potential of CoreXY vs bedslinger, beside the easier enclosing and slightly faster speeds, is that it can be just as good if larger (compared to large bedslingers that need to be even slower, and take up huge space). This is not just for large parts, but also for printing many small parts - with current build plate on a MK4 (250x210, Z height is irrelevant in this case), I can't fully use a night printing shift, as the print time cannot go over 4-5h (parts are quite small), and if the printer is even faster, even less of the night is used. With a build plate of e.g. 270x270, more parts can be fitted in one print, so night shifts would be ~50% more efficient.
That being said, I will probably buy at least one CORE One, but if I need more printers later, I'd prefer slightly larger ones. Although they would be more expensive, so that must be taken into account as well.
RE: Prusa Core One - Intial thoughts......
For sure everyone has his own applications and wishes. Some just want a large build plate to host many small objects built in PLA, so the Z-height that a large size printer usually has is just plain loss of space for them, and the enclosed room is just hindrance. Those printing mainly nylon or ASA will want the climate control but have no real need for large build volume because the warping may be delayed but it will strike at some point. A generic printer thus is always a compromise, and everyone can complain about the design not being pulled further to support the way they will want to use it. Nobody is happy about the printer being more expensive because it better supports someone else's needs.
RE:
I such as a prognosticator, but here goes: this current COREOne will become the middle child of a trio: the CORE One < will slot below with a 200x200x200 volume; Core One > will top-off the range with 300x300x300. Mini will stay on for now with needed update as long as there is demand. XL will be the multi head solution in at least the current and XXL format although 2 multi head in a slightly smaller footprint would be awesome!
RE: Prusa Core One - Intial thoughts......
Some good closer up shots of the Core One here....................but I'm gettin a bit of OCD about that nozzle being installed diagonally rather then straight! LOL

RE:
Looks great- What I am missing is a compact, enclosed "MMU4" - Filament coil holder... And maybe some internal memory (no need to have the USB stick sticking out of the display)
RE:
Not sure I love the hardened nozzle. Our experience was negative. Everything we print these days is NylonX, a PA12-CF40 based mix. It is erosive and we were looking forward to hardened nozzles on MK4. Unfortunately, those nozzles clog too quickly, so there's no advantage. We went back to brass nozzles, which print continuously through their lifetime. The labor input to clean hardened nozzles completely erases all savings. In addition, it's more convenient to have a scheduled downtime, rather than an emergency. A clogged nozzle always fails a print, too, so there's that loss of money and time as well.
Regarding the size, XL was too large of us, but Core One looks just right. It's not impossible to re-plan printer racks, but it's a hassle. BTW, XL was just tiny little bit too large. Because of its CoreXY design, its outside dimensions didn't grow in proportion to increased internal volume. But unfortunately they grew just enough to ruin everything.
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.And the screen/display.....
Of course, the electronics and the display 😀
And the heated bed, the steel sheet, the NEMA motors.
And the power supply, although the Core One uses 2 power supplies so the second will be part of the conversion kit.
RE:
What gives you the impression the Core One has 2 power supplies? I see two boxes on the back, the power supply and the electronics enclosure. Where are you seeing a second power supply?
