Good afternoon,
Today they replied that it is probably the MC or AP board or even the screen that needs to be checked, and they will send me the replacement parts.
I replied that I don’t think it’s right that I have to fix the problems, so I requested a refund due to a critical fault, as it’s within 14 days of receipt.
Let’s see how long they take to reply again… I think they’re a bit slow, but I’m confident that everything will be resolved satisfactorily.
Title: P2S – Hotend trying to become a small sun? Melting sock, melting sticker, maybe melting my sanity.
Hey everyone,
I got my P2S around 10 days ago. At the beginning I honestly thought I’m just too stupid for this printer. A couple of prints failed in absolutely phenomenal, almost artistic ways – you know how Venom looks in his original form? Yeah, like that, just… beautiful failures.
To be fair: I’m still learning.
I also didn’t know much about filaments at first and accidentally bought PETG HF refill boxes (no spool) instead of “with roll”. So my very first proper roll I printed with was PLA (not PLA+, not CF, just basic PLA).
Because I’m apparently a genius, I also dried my filaments – including that PLA roll. That PLA spool got deformed during drying and became basically unusable. So I already needed a new spool, and this time I decided: no more PLA, let’s go PETG.
I took the new PETG HF, used the PETG HF nozzle with one of the replica models, because on the P2S it seems not possible to override the model settings from PLA to PETG in the way you’d logically expect.
Result:
On the first layer it started to go full spaghetti, then clogged, then melted the silicone sock, and then basically welded (or at least glued for eternity) the nozzle / hotend to the printer’s heat exchanger on the toolhead.
By the way: the AI never caught a single spaghetti fail. I had about six of them, and it didn’t detect any of those.
I tried to clean it up and did a cold pull, so I think it still works… but something feels terribly wrong.
A few more things I’ve noticed:
Some, if not all, heat sensors in the print head (most likely the thermistors) are badly off on my device.
Why I think that:
So either:
One thing that really worries me:
If the AI can’t even catch obvious spaghetti fails (I had six of them, all ignored), and the printer apparently overheats enough to melt silicone and a warning sticker, that doesn’t feel very “safe” for an enclosed system.
Bambu support so far has been… let’s say: extremely delayed and maximally asynchronous. Even when the agent is still shown as “online” in the chat, I don’t get any response anymore. When he comes back online: still nothing.
So I’m here to ask:
I really hope Bambu sorts this out properly for us early adopters of this “finished” second-series product.
Otherwise, I’m sure a small consortium of influencers would love to review a printer that tries to turn its print head into a miniature fusion reactor. 
i would have uploaded some pictures to show you guys but i am not known enough.
Update.
They told me to buy a new heater element because its not covered under warranty… FFS.
i am still within my 14 Day Period - tomorrow this piece of faulty BambuLab Printer will be express shipped to where ever they are at, anyone got experience on that process ?
An early adopter of any complex product, not just Bambu.
Posts like these do remind me that maybe I should hold off purchasing that H2C on initial release.
Why shouldn’t PETG-HF be able to print on the P2S??? I’ve printed a number of models with the BBL black PETG-HF with no problems whatsoever. Sliced in BBL Studio, filament recognized by the AMS-HT, then printed flawless and as fast as PLA.
Did you use a non-Bambu nozzle? Then that might be the item causing all this problems.
Strange, I am having the same issue with my p1s the only light is the power switch the outlet has been changed and all the things like that
Chat is not to be used for technical support like this. Submit a support ticket.
It’s not clear what the issue is. What’s a PETG HF nozzle? Why is it not possible to change filament setting?
I did not say it’s not possible I did do couple PETG HF Prints and all with the exought HF Nozzles by Bambu - all I have is made by Bamb
It’s just not possible to change settings of the Models on the printer directly. Without an extra slicer to use.
A PETG HF Nozzle is the by BambuLab recommended Nozzle for their Filaments with HF in the Name…?!
It was always and only original Bambu Equipment.
When printing a model that came with the printer already sliced you cannot change anything g just print. Then they should presliced their BambuLab Filament Roll in PETG instead of PLA.
Anyhow, Support sucks so bad I’m done with this company. Soon there will be around 250 BambuLab Printers cheap for sale. They had no idea that I am managing a giant fleet of their printers at couple company’s - soon there will be prusas only…
Yes, like any complex product—but since the H2D launch, quality control has gotten noticeably worse, the software isn’t progressing, and firmware isn’t being developed or released in a reasonable timeframe. I’ll get the H2C too, but definitely not at launch—I’ll let others do the field testing for me…
Hmm, you are still learning how to do 3D printing, you melt a PLA printed spool because you dry you PETG with a dryer, you don’t know how to upload a picture here and your are saying that you are managing around 250 bambulab printers in different companies… this don’t work out for me but I is just my opinion.
If someone pay me to manage 250 3D Printers… maybe I have a different understanding of that kind of work… Don’t get me wrong - I’m still learning since I started 3D printing with a Pruse Mini a couple of years ago. I manage just four printers here and help two friends with their printers without any payment so I’m not a pro like you…
I have two P2S here and the first one is running around 250h and the second one is pretty new with around 50h. One problem with a damage with a silicon part at the printhead behind the nozzle but nothing problematic. I open a ticket, they want a picture and we figured out, what is broken. That it take a couple of days is “industry standard”.
But as every new product there are good and bad batches - this is typical all over the industry and absolut normal nowadays. My pursa mini for example had a dead sensor after a couple of days. prusa sent me a new one out and done.
And keep in mind as a user you normally see the bad reviews and post in forums like this.
Well… My P2S is in coma soon about one month. Worked two days and thats it.
And no solution and as far as I know even support cant figure out whats the problem.
Today arrived brand new MC Board - second one. Changed it and still the same - printer in coma and thats it. Hopefully tomorrow or day after tomorrow support will answer and I guess that they offer again to send new MC Board (in that case it will be third) :)…
May be it’s normal nowdays… maybe it really is industry standard… but to be honest - i’m quite disapointed in whole Bambu Lab.
It’s my first experiance with BL. Not the best start I guess.
Hi I decided to check the P2S thread to see if the experience with this new machine is positive. Your experience and other users in this thread having similar failures does not instil confidence in the BL business model of using the customer to repair factory production faults.
The elephant in the room seems to be inadequate BL quality control and releasing printers into the market prematurely before bugs and issues are resolved. This applies to both hardware and software.
Like you I am new to BL and was planning to purchase a H2D (upgrading from Creality 10S) but it seems the experience with the P2S is similar to the H series with production/quality control issues continuing.
I am holding off on my purchase decision as AU$4K for a H2D is a major commitment and I am trying to avoid an expensive headache! I simply want a printer that works out of the box!
I do hope you get the printer sorted quickly - keep us posted!
If something changes, I’ll probably keep you posted. Although… I don’t know. Right now it seems like I’m just giving up. If it doesn’t get resolved soon, then… the best thing I can do is probably either sell the printer for a couple of beers or just give it away to someone who has the time and the nerve to revive it…
I’ve already lost a lot of time. And basically, this dead printer has already caused me a loss financially. Now I just want to get rid of this mess and as soon as possible. If the 800€ I spent is just “school money”, then so be it - I’m stupid for rushing and buying it on the first day. My fault.
It would be especially comical if I tried to revive my comatose P2S and wasted more days and missed out on the Black Friday offer for, for example, the Anycubic Kobra S1 Combo, and then it would turn out that my P2S is finally dead anyway. 
And I would pay full price for the Kobra after a while… Then I’ll really laugh my ass off. 
I’ve been researching buying a new printer for several months now. At one point I had three printers to choose from - the Kobra S1 Combo, the Creality K2 Combo and the BL P1S. I almost bought the P1S. At that time, I thought that since I wasn’t in a hurry, I’d do some more research and who knows, maybe there would be a good price during Black Friday. There were a few things about the P1S that I didn’t really like, so decided to wait little bit more. At the same time, there was no need to get a top model (H or X series)… Until one beautiful (or ugly) day, a letter from BL popped into my email. “Something big is coming”… If I’m not mistaken, it was October 14th… I opened the link and it turned out that a completely new printer (P2S) was about to arrive and since the price was so favorable, there was no plan to get any additional discounts for it on Black Friday. Well, it sounded like a dream! P2S was EXACTLY what I needed and what finally tipped me towards BL and I decided to give up Anycubic and Crealty.
And now… P2S is dead, Anycubic is still on sale at a decent BF discount, but I have no idea for how long. It would be wiser to order it now… but what if by some miracle my P2S comes back to life? I don’t need two printers…
Extremely awkward and stuped situation.
To learn about P2S, read about it on Bambu Lab wiki.
https://wiki.bambulab.com/en/p2s
There are also courses in Bambu Academy. I saw one for P1S. Not sure about P2S yet since it is new. You may want to wait until P2S course is out.
Edited: P2S course is out, as pointed out by Toy4584

Another way to learn about 3D printing is to watch YouTube videos.
Yet another way to learn is to go to a local maker’s space that has 3D printers and watch how people use it. Chat with them to get exposure to some basic terms.
If Im’ not wrong - Academy is out for P2S too!
This is really bad news - I think it’s called a “lose/lose” outcome.
You have lost because you didn’t get what you paid for and BL have lost you as a new customer and potentially new customers like me!
They have also lost credibility as a market leader of quality out of the box solutions!
if BL wants to retain a decent reputation it needs to step up to the plate and replace the printer - assuming all reasonable fault rectification steps have been taken without success. This forum should firmly reject the proposition that a user can be stuck with a dead BL printer.
If you purchased an iPhone that failed (like your P2S) I have no doubt Apple would replace it.
The sign of a good company is how it responds when things go wrong after purchase and so far I am left underwhelmed with too many negative experiences like yours.
While it may be a PITA - don’t give up your legal rights and keep pushing until you get a replacement printer.
Well… just few minutes ago got answer to my ticket…
Looks like BL will replace my machine. I would really like to believe that I didn’t make a mistake again when I accepted BL’s offer and replaced the printer instead of getting a refund.
We’ll see about that later.
That is really great news - mmmm… may be BL do monitor threads like these(!)
My thoughts are be thankful you have been offered a replacement P2S printer which I hope restores confidence in both the product and the company.
So…
Yes, the printer is faulty and who knows, something might be wrong with the new printer too. But I have not a single bad word to say about BambuLab or the support. I think the support is very helpful and reasonable. The response time has also been very reasonable.
I certainly don’t think I should give up on BambuLab. Far from it. Faulty products do happen. I just got “lucky” with it.
So… I decided to give BamuLab a chance anyway.
