Hey everyone! Sorry if I missed something out, but I'm curious what's you experience with shipping times to EU? I ordered my printer (Core One 2nd Gen) last week and nothing happend yet. I saw a bunch of people being concerned about shipping delays, but I wonder if this is only related to pre-purchased articles? On my purchase status page it still says 2 - 4 days of expected shipping time, but that's already reached.

When I ordered the printer, the shop displayed it would be in stock. Maybe I'm just not patient enough, however what's your experience?

Owner of both the Core One and Core One L here. I love the workflow of these printers, which is ultimately what led me to sell my Bambu Lab H2D.

It's worth mentioning that during the entire time I owned the H2D, I HAD ZERO. NADA. NONE. Not a single issue with it.

I sold it primarily because of Bambu Lab's questionable business practices, cloud dependency, and the general lack of trust I had in the company's approach. I never felt entirely comfortable with the idea of having my designs sitting in an ecosystem I didn't fully trust. Do I have proof that Bambu would steal a profitable design? No, I don't. I'm not going to pretend otherwise. But concerns about intellectual property and the copying of products by companies operating in China are part of why I was uncomfortable. That's a concern and a perception, not evidence that Bambu itself has stolen my designs.

Now, looking at where things stand with Prusa, I'm starting to question whether I made the right decision.

Bambu has had automated Pressure Advance calibration for quite some time, while Prusa still doesn't offer an equivalent integrated workflow. We have only recently received wireless tag recognition for a single filament roll. Perhaps other improvements are coming, but some developments feel slow and out of sync with what's already available elsewhere.

Not long ago, CNC Kitchen demonstrated a tool he designed himself to automate Pressure Advance calibration using measurements from the printer's nozzle probe. I'm going by memory here, so forgive me if I'm getting some of the technical details wrong, but the result was essentially automated PA calibration.

This would save me HOURS of filament tuning. And because PrusaSlicer doesn't currently offer the workflow I want, I've had to resort to OrcaSlicer, which I simply don't enjoy using as much.

Josef Prusa himself jumped into the YouTube comments to say that this functionality was in the works. Great. But I'm increasingly skeptical of promises about upcoming features. I've seen enough examples of features being announced or discussed that take a very long time to materialize, if they ever do.

Then there's Wi-Fi.

Both my Core One and Core One L became unusable over Wi-Fi following the 6.8.1 firmware update. Both are now running firmware 8.0, and after countless hours with Prusa Support, I still don't have a solution.

We've replaced Buddy boards, replaced Wi-Fi boards, and reflashed earlier firmware versions. Nothing solved the problem.

Both machines worked for months on the same network, which hasn't changed. The problem appears to be that the printers lose their Wi-Fi functionality after losing connectivity to Prusa Connect. At that point, the Wi-Fi interface effectively disappears. Running the network wizard reports that no Wi-Fi hardware is connected.

I've submitted logs and other information through GitHub. Eventually, I gave up waiting for a fix and purchased an additional mesh access point so I could connect both printers through Ethernet.

Think about that for a moment. In 2026, I have two otherwise excellent printers that I cannot reliably use over Wi-Fi, despite extensive troubleshooting and hardware replacements.

PrusaSlicer is another area where I have mixed feelings.

I genuinely prefer it to the alternatives, and I'm glad to see development continuing. The new beta looks promising, and I appreciate the direction things are heading. But it still feels like it has a long way to go before it becomes a workflow I want to use every day. While testing the beta, I found myself wanting to close it and return to something else. I can appreciate the potential without pretending it's ready for my daily use.

And now we have the upcoming Bambu Lab H3C, while Prusa's INDX system is still being developed. Add the firmware issues, the slicer shortcomings, and the uncertainty around when promised features will arrive, and I'm genuinely on the fence about switching back.

The financial cost and the compromises associated with Bambu's cloud ecosystem might ultimately be worth it if I can spend more time printing and less time troubleshooting, waiting for updates, and working around missing features.

The irony is that I experienced none of these operational headaches with the H2D. I owned several Bambu products and generally sold them before their next flagship arrived. I switched because I wanted an ecosystem I felt more comfortable with, not because the machines weren't doing their jobs.

Prusa machines are excellent in many respects, and I still prefer aspects of their workflow. But I'm beginning to wonder whether owning them requires more patience than I'm willing to invest.

This is me thinking out loud, and I'd genuinely like to hear other people's opinions. It's perfectly fine to disagree with me.

For those who have owned both ecosystems, how do you feel about the trade-off between Prusa's approach to openness and ownership, and Bambu's more mature automation and overall workflow? At what point do you stop waiting for promised features and choose the product that works best for you today?

Hi everybody,

IHave got my MK3S for a few years now and recently got a new hotend because of a blob of death. My bad.

I had no issues with thermal so far and that's why I have no clue what to do.

Well then... since yesterday my printer wont print anymore, because of a thermal error with no further detail.

I have tried the thermal model calibration... that one went through flawlessly. I don't know how. Still the prints fail because of the thermal error while heating up.

I know it is quite vague, but any idea or road which I could go down?

Thank you in advance.

Edit: just found out I could do the PID tuning and the first print is running for 10 min now (it used to fail while heating up)

Hi together, this is to All own an ht90. My ht90 just died, during midprint it Shows me printhead not detected, settings Menue not acessible too.... i tried of course the other printhead, no change too....

Is anybody out there had this failure too and know an fast way bring him back to production ?

Around five weeks ago, one of my Prusa XL's bearings failed and I contacted Prusa support. After hearing literally only positive things about them, I was honestly curious whether the support would be THAT second-to-none good. And yes, I had a great talk with a competent person and we agreed to swap a few parts, which should probably solve the issue. I got a confirmation that the parts are kinda on the way and that I would get more details on the shipment "in the next days".

That was five WEEKS ago. Since then, I've contacted support a couple of times to get an update on the parts. Every time it was a nice "oh, we are sorry... don't know what takes so long... logistics... BUT the parts will be on the way in a few days".

More days and weeks passed, as did one of the hotend thermistors, which then put my printer completely out of order a week ago. Same procedure:

"Hi, I have a problem with... also, I've been waiting for my parts, or AT LEAST an update, for like a month."

"Oh, sorry to hear that... sure, let me see, hmm, will be on the way in the next days."

(SpongeBob narrator: "A few days later")

No parts, no update, no printer, but a nasty uni thesis deadline for which I kinda needed (and need, lol) a printer. So same chat again.

"Hi, it's getting frustrating..."

"Oh, sorry to hear that... sure, let me see, hmm, I see it's been a while."

"You don't say..."

"I will get back to you later today via mail with an update."

(SpongeBob narrator: "Later today")

Nothing.

And it really begins to absolutely bother me. That's literally a 5 grand printer with the enclosure, less than 2 years old. When my 250 EUR Bambu A1 broke, before I replaced it with the XL, it took two days to ship the parts and 2–3 days for them to arrive. Without days of begging, reminding, etc. Is this considered "usual"? Or am I just too impatient?

Also, it really bothers me to do the "Karen wants to speak to the community manager" move, but honestly, I literally cannot afford (time- and money-wise) to have a 40 kg brick in my living room that should kinda do university stuff for me. I mean, it's not a machine that has been out of warranty for 5 years or so. It's literally a warranty claim (or now two).

Also, don't get me wrong, I enjoy using the XL more than any of the like 5 printers I've had in the last few years, and I fully support Prusa as a company. But I would just be thankful to have the printer working again. Colleagues were kinda surprised, since usually (at least when they had problems a few years ago) the issues were solved kinda instantly. Selling the XL and switching back to Bambu Lab is also an option, but I'm not really considering it at this point, since the XL was a long-term dream of mine. But if it's not possible to fix minor technical stuff under warranty in less than a month, I'd probably be better off selling it before something more important fails at some point.

So yeah... any help would be appreciated. Or any hints on how to contact Prusa in a way that actually leads to progress. Or maybe someone from Prusa support sees this and has an idea of what went wrong here.

Im happy with the multi colour and singlebmaterial printing but ive got a couple of models planned that would really benefit with using PLA supports with PETG for the print due to overhangs.

Does anyone have any settings or tip?

In preparation for the US Halloween holiday where kids go door to door in costume expecting candy, I'm adapting to the US economy's current sky high candy prices (especially chocolate) by offering something different. For those who choose, I have a variety of 3d printed fidget toys - spinning rings and infinity cubes each in an assortment of different colors. I've been printing batches that maxed out the print area on my MK4S.

Bonus picture: golden skulls using the Eryone silk gold filament I recently won in a contest here on Reddit

I'm having lots of problems with the filaments not loading properly they are not lining up with the filament selector. Is there a secret of how to cut the filament ends to make sure they go in the right way? I have a MK4S with the MMU3 that I assembled from a kit.

Hi, will the XL print the Prusa TPU ok or do i need a different nozel? Also will a print with both PETG and YPU print and stick together ok? (assuming the design caters for PTU movement)

I even washed the build plate because I was afraid it wouldn't stick😭

Hi,

I finished upgrading my Core one to INDX on October 12th, but I'm having an issue with my INDX toolhead where the load cell functionality is very noisy and is defective. This makes it unable to complete offset calibration. Prusa sent out a new cable, but that did not resolve the issue.

I have continued to chat with Prusa about this and now I need to return the toolhead. They have said it takes 5 - 7 business days to even get a return shipping label. It's now been 8 days, and all the chat can tell me is I need to wait several more days for somebody to email me from [info@prusa3d.com](mailto:info@prusa3d.com)

This has been a very frustrating experience. Anyone else having this issue? Here's the YouTube video I recorded earlier: https://youtube.com/shorts/sx-Vb1dN_Bg

The MK4S kit is $709. The fairly new Bambu Lab X2DC with AMS combo is $789.

I’m not sure how Prusa can compete with this. I wish they could, because I love them, but the competition is getting really hard!

So, just received my INDX after probably 8 months or so of delays and nonsense. Posting because I've seen so many mixed reviews at this point that I almost don't even want to put it on, just turn the other way, return it, and get a Snapmaker U1 or something...

Currently have an MK4s, Core one+, Anycubic Kobra Max 3, and a Core One Oak (This is more of a collection piece, I've only printed a couple things on it). I also have some other printers but the ones are the ones currently in the house and not storage.

Im a software engineer by trade, so needless to say what Josef Prusa has done for open source FDM I respect and greatly appreciate, but, I've had terrible issues with my core one + the last few months, my MMU3 on my mk4s literally took the better part of 8 months to finally get working right, and I just don't know if the Indx is even worth it at this point.

Any input from anyone with the INDX upgrade, or anything helpful at all really about whether or not to stick with Prusa or just worry about getting something that works when I need it to work.. Because I need it to work when I need it to work.

Hello, I brand new to all of this so I apologize for probably sounding like an idiot, I really want to get into 3d printing but apparently picked the printer thats the hardest to install? (Flashforge creator pro 2)

I saw someone made a profile of it on GitHub with detailed instructions on how to install it with Python an all of that, but truthfully i didn't understand a single word.

So what I've come here to ask is if anyone would take the time of day to make a video or visual reference for the instructions so I can understand it easier, it would mean the whole world to me 😭 ❤️ I don't understand the whole "Python" app thing

When I ordered on the day it was announced. the website said 2 week lead time. ok that's fair.

Well, we're on week 9 now, with zero communication and still no shipping date or info.

Definitely not happy with how Prusa handles these product releases and wish they would change how they operated, in order to provide better transparency.

I have owned my MK3S+ for over 8 years after building it from a kit and I'm feeling it's time for an upgrade. Two of my biggest barriers to printing more are the slow bedslinger speed and hating the nozzle change process, both of which are resolved on most modern Core XY printers. I would like multi-material (and especially to play with multiple nozzle sizes during the same print) but I have no clue what I'm missing out on and I've survived this long with a single filament tool, manual color changes, and assembling prints out of different colored pieces.

I've been in research paralysis for a couple of weeks because it seems like there's no perfect solution on the market, and each one is asking for some sort of trade-off. Bambu's prices are obviously compelling but I don't think their closed-source ecosystem and DRM nozzles (lol) is something I can support. Qidi and Creality seem to generally have questionable QC, as I've experienced in the past with an out-of-square Creality I quickly returned. Building a custom Voron 2.4 with Stealthchanger is likely the path I would have gone down before having a baby, but I likely can't spare the 60-80 hours to build and calibrate it properly at this point.

I'm aware of the mixed reception of INDX and don't need to rehash it. I know Core One L+ will be a massive upgrade for my single material prints over MK3S+ and bring several QOL features, however paying $2300 for a single toolhead printer in 2026 almost seems crazy until you look at the tradeoffs other brands ask of you. I've never had an issue with Prusa, love their upgrade pathways and keeping things mostly open source. The only way I'd probably regret getting Core One L+ is if they can't iron out the kinks of INDX by the end of next year.

The Black Friday deal with free shipping ($250 savings for me) on non-INDX printers plus the $50 voucher is obviously meant to push the printer now, INDX later upgrade pathway. Anyone else go MK3S+ to Core One L+? I know Prusa has had issues in the past with several products and they all got solved eventually, so I should be a little more trusting but I just want to make sure I didn't overlook something in my consideration of the current printer market landscape.

Does anyone have a list of items I need to print for the double spool roller inbxx. There are alot of files in the download and wanted to make sure I print the right ones.

It's shipping! Decided to wait for the black Friday deal and free shipping, glad I did. Eventually I'd like to get the 4 head INDX upgrade kit. Is this more expensive than your typical core XY? Absolutely! And for people who really want a cheap multi tool head, I think printers like the Snapmaker u1 are great. But for future upgrading and long term reliability, you just can't beat Prusa.

I made a small figurine of our beagle from a single photo using snapshapy, exported the STL and sliced it in PrusaSlicer at 0.12 mm with Prusament PLA. Body and face come out great, about 70 mm tall. The floppy ears hang down at a steep angle and every time they print as spaghetti or snap off when I remove organic supports. I've tried painting on supports and printing slower. Would tilting the model back 30 degrees help, or should I split the ears off and glue them on after?

Currently at Core One, have the 8T INDX conversion kit (includes the Gen2 +), is there anything from the Core One + upgrade kit that needs to be installed first? Does not look like anything is required to do before I begin the Gen2/INDX update. Thank you for any reply.

I usually buy build plates for my Core One+ from AliExpress. For that I use ads for BambuLab A1 build plates.
Question for the community: Is anyone here buying build plate for Core One L from AliExpress? And if yes, how are you looking for plates? only by size or are you using a specific printer model for search?
Because reality is, looking for Prusa printers build plate we do not find many options available. but when we expand the search for other print models, we can find.

Thank you,

I made fan shroud in PPS-CF as a first test before printing more serious stuff. Amazing filament.

Ordered my INDX upgrade the day it was announced; shipping still “TBA”, no batch assignment. Is this normal or should I contact sales?

When a print finishes the bed has an awful grinding noise when it lowers. I don't particularly remember it being this bad prior to the firmware update 7.0.0, but it is definitely more noticeable. Do I need to grease something somewhere?
