Core One and MMU3
I bought an MMU3 for MK4 but have not installed it yet. Thinking of upgrading to the Core One. Will my current MMU3 work with the Core One?
RE: Core One and MMU3
Im in the same boat, but yes, the MMU3 is compatible with the Core One. This was mentioned din the promo video, and was even shown in it at one point.
It will hook on to the top of the rear panel and work as normal.

RE: Core One and MMU3
I have a MMU3 in its box right now - wondering whether to bother setting it up with my MK4s or whether to just wait until I've converted to the Core One (which would be several months away I guess) before bolting on the MMU3......guess it would make the conversion straightforward without having to remove the MMU3 etc first, and I can start afresh with multicolour and the Core One.....

RE: Core One and MMU3
meh, build your MMU3 and get comfortable with it. installing it for the Prusa CoreOne is not going to be a rebuild of the MMU3. I built and installed the MMU3 a few months ago and just finally modded it to an Ultimulti C6 -- which is a substantially more reliable design. But none of that is due to it being installed on a Mk4S...
RE: Core One and MMU3
Yeh I'm going to get the unit build when I get some time - it was more making the changes to the MK4S, or whether to leave it 'stock' for the Core One conversion. Then again, I guess it's just the idler swivel door that changes really......

RE:
I just finished a torture test 4000+ filament swap 4-day print of the Deadpool bust at 0.10 Fast detail profile and 5 colors. 3 filament issues that were all resolvable. 1 due to my error. But, they all included me opening the MMU3 to see what was going on to make a decision on how to solve. If you use the stock Prusa method -- this involves an Allen wrench or hex ball driver and work. The Ultimulti has a quick lever and you're in the MMU3 in seconds... and you don't have to worry about if you screwed up the correct tension when you close and lock the lever. That's truly priceless and worth the mod. So, you can use stock parts and waste the filament when you move from stock to mod or just step forward into a less frustrating model. You really won't have the appreciation of the Ultimulti without suffering first with the stock parts 🙂 If you do print the Ultimulti parts, make sure to print the frame in a strong filament since it only latches on one side. I used PETG-CF.
I figure that the Core upgrade kit will be available in August since Prusa is always late (Pilsner Urquell effect), then my order will take until next Christmas to fulfill. So, this is a next Christmas discussion. In the meantime, I'll enjoy the quality of the Mk4s and look forward to getting rid of the bed slinging brims and glue for tall prints.
And don't forget to only use the standard 0.4 nozzle when using the MMU3. The high flow CHT nozzle also works, but you'll waste more filament in your wipe tower to clear it.
RE: Core One and MMU3
When making the ultimulti version, beware that it suffers from the same defect as the original Průša. That is, it has freer positions 1 and 5 in the idler cylinder and the pins that hold bearings 1 and 5 in place will fall out of them.
RE: Core One and MMU3
My MMU2s experience makes me want to let the brand new CORE model get a little field time before I make it even more complex. I’m really hoping for a dry box, really drying box solution for the CORE/MMU3, since it will handle high temp filaments that seem to have more of an issue with moisture.
RE: Core One and MMU3
I think a good model for Prusa to look into is a CORE Two: dual tool, 300x300x300, with a mmu3 option for the second tool. That would be all kinds of cool! But as of yet I don’t have any use for the mmu let alone two tools.

Hello everybody,
I have few question related to this topic...

First: when you wrote upgrade kit available in August, you mean the MK4S -> Core One kit or the the MMU3 kit ? Because I was looking for information about the MMU3 and notice in the shop there is no option for the Core One...
Second: I have for a year a second and Mini+, before that en Ender 3 for few years. For few month, I'm thinking about a better printer than the mini and have interest for Multi Material printing. The announcement of the core one act like a trigger in my mind, so I'll probably jump the step soon or later. There is the faster but more expensive option to buy a MK4S with the MMU3 and wait few month for the upgrade kit to the Core One...
If the shipping for the Core One start next month, I expect to have one in February or March (or later ?) So wait to August to have the MMU3, it's relatively a long time...
Best Regards

The MMU3 is already available - it is the same unit that will be used with the Core One. The Core one is more an enclosure and axis change, the extruder itself doesn't seem too different - just the placement of fan and nozzle really - hence why the upgrade path from MK4s>Core One is an option. As a result the current MMU3 will be fully compatible with the Core One and remains Prusa's main multicolor solution (albeit with a possible bracket redesign so it sits on the rear enclosure panel of the Core One - either way this should be an easy print). There is no other multicolor solution specific for the Core One.
Prusa have historically never been good at keeping up with the demand a new product launch generates. As a result, even if pre-ordering opens in January, don't expect to receive your unit very soon. It has been common for shipping dates to continually slip (multiple times in fact) and for items to be shipped weeks, sometimes months, after originally promised. I can see the Core One being rather popular, so delays will most likely be a certainty.
If you are hoping on a Core One, I would expect a several month delay - moreso for the kit, which is always a very popular option with Prusa machines.
If you absolutely need a machine now then get the MK4s. Build and explore it, Get used to it along with the MMU3. You can then convert to the Core One when available, and the MMU3 will bolt straight on too, with all the experience you will have gained with how its used. Alternatively if you can wait, then it would be good to do so - but as stated, be VERY flexible with your delivery expectations.
I already have a MK4s which I will be converting to the Core One when the kits are available. I also have the MMU3, which I am currently building right now. I intend to bolt it onto my MK4s and get it dialed in etc - I'll then shift it across to the Core One after my MK4s is converted. This way I can continue to print right up until the Core One conversion kit is finally delivered, without going through the downtime and frustrations of slipped shipping dates every few weeks!

Wow, that's a very complete answer, thank you! You've confirmed my thoughts about the delays.
I'll take some time to think about it, and maybe wait a few months before ordering a unit. By then, there should be more troubleshooting feedback available and hopefully a better stock situation.
The Mini+ does the job very well for me. I push its limits on some projects, and while it’s a bit restricted in certain areas. I'm struggling with bed leveling (Silicone Bed Mod) with print that occupied all the bed but I’m still happy with it and learning new things. Patience might indeed be the way to go!
RE: Core One and MMU3 (New Assembled Combined Order)
I'm in the US and want to order an assembled Core One with the installed MMU3 but it isn't available for ordering. Any ideas when this combined assembled option will be available? Any idea when it will be available to get from US distributer to save on shipping? thanks

From what I read, it will be several months before US produced Core One's are a thing. The MMU3 "where should we have it?" decision that has it not as a addon option currently will surely be resolved before then. I'm much more concerned with higher import costs from the upcoming tariff Trumpocalypse than the shipping fee.
RE: Core One and MMU3
The MMU3 is already available - it is the same unit that will be used with the Core One.
Not exactly:
"Q: Why can’t the camera, MMU3, or the filtration system be added to the order at launch?
A: (...) As for the MMU3, we are finalizing the way it integrates to the printer’s top section."
RE:
That could mean they change the brackets, since it will hang on the core one differently then it does on the MK4s, but the MMU3 unit itself will be the same unit as it is now and fully compatible.
From the blog:
"Plus, you can count on full support for the most efficient single-nozzle multi-color solution, the MMU3. The unit is fully compatible with the Prusa CORE One and it will allow you to print beautiful, colorful objects with up to five filaments at the same time."
Im also sure I read somewhere that they are looking at a way to place the spools in a drybox type solution so its neater etc - but I can't remember where I read it!

RE:
I spoke to a Prusa employee at Formnext about the MMU3. After I showed him my solution without a buffer, he said that a similar system would be used on the Core One.
He described the current MK4/MMU3 setup as a bit messy and not very space-saving and that a much better solution is being sought for the Core One.
The filament is to be housed in a box, he couldn't or didn't want to say anything about the buffer. I saw a picture, unfortunately I can't remember where, where the buffer could be seen in the right-hand recess.
Since a dry box was also visible for the single spool, I assume that Prusa is now paying more attention to dry storage.
I am really curious to see how they solve it 😉 It can only get better 👍
RE:
Yeh Ive seen a single spool dry box mounted to the side of the printer in a previous video, and I think they will have a solution similar to the (un)original Drybox thats on printables at the moment to sit on top of the machine......as for the MMU3 itself, it will continue, maybe with some new 'feet' to place it on the top rear panel of the Core One.......hopefully just something that can be printed rather then another 'upgrade kit'.....

@Rainer-2, can you tell us more about your bufferless solution?
