I would take the X2D replacement. I had a similar problem with 2 Creality K2 Pro printers with never ending problems spanning 4 months. I bought a H2D after getting a refund for one of the K2’s. The other K2 they wouldn’t give a refund but a replacement. I sold the replacement when it arrived for a bit less than the purchase price and bought a H2S (I spent more but glad I did). Asking BL to swap out a different printer is probably outside of the customer support policies and because of that, you’re swimming upstream. If you want a lesser BL printer, sell the brand new, still unopened X2D when it arrives, . I would demand a new replacement and not a refurbished one. I battled that issue and the logic I provided was this: The new printer I got had so many problems that I couldn’t really use it, it was defective. It was a new defective printer. I demanded a new replacement because the refurbished replacement is a used “fixed” printer with many parts with time on the clock and could fail earlier than a new one. Good luck
I would definitely accept the replacement X2D, I use mine heavily with no issues, in fact my 1 year old X1C is collecting dust!
Does anyone love how Bambu Labs is having customers to be beta testers after accepting their money?
Not Sure! My P2S today crashed a 5 hours print after about 4 hours 30 min. (nozzle clog!)
Don’t think I will go for another Bam..ab!
Bambu Lab PETG Basic.
Hey Roland, Welcome to the forum.
Nozzle clogs are not uncommon. Its up there with bed adhesion issues for the most common failures.
Unless it is a repeated issue, it is not something I would blame the printer for, and changing to a different brand wont change anything. Ive seen nozzle clogs on half a million dollar industrial machines.
They happen every so often, if it an issue that happens over and over, then it is a problem with machine/nozzle. I hope this can help!
I would get the replacement printer, and if there are issues with the new one you can request for refund. And with the money from it you can buy like 2x p1s or something else. But make sure to test the new one very well out of the box.
I also have x2d, mine is working but it is inconsistent between bottom and top layer. Which make me spend lots of time and filament, for calibrations and tests. And I bought in Bambu environment with the exact opposite idea, to just print and not live between calibration cycles and endless setting changes.
My experience with the bowden extruder is exactly the same. It is hit or miss for support and anything different than PLA. And it is slow. So for me currently this looks like expensive 2 nozzle PLA printer. And I am also considering buying more cheaper printers. And maybe one real engineering material printer. As this one is not really made for high temp things all the time. More like PLA printer with lots of other half baked features.
Finally someone understood why I keep comparing the X2D with the P1S, probably because you actually own the same machine.
When Bambu told me they would only replace X2D for X2D and wouldn’t exchange it for another model, I actually asked for a refund. They refused that too.
I eventually accepted the replacement X2D, but strangely, four days later they’re still “discussing internally” what solution to offer me. I don’t think that is particularly normal after I’ve already accepted their own proposed solution.
Given the choice, I’d honestly take one P1S with AMS 2 and one standard P1S. The AMS drying function works extremely well for me, so that combination would actually be more useful for my work. I’d even accept refurbished units and pay another €100–150 if necessary.
That’s really the point I was trying to make earlier: I’m not arguing that the P1S has better flagship specs. It obviously doesn’t.
For me, productivity and redundancy beat flagship specs just for the sake of having flagship specs.
And yes, your experience with the auxiliary Bowden extruder sounds almost exactly like mine. It’s nice to finally know I’m not imagining it.
Beta testers? More like unpaid field technicians.
They send the parts, we repair the machines, report the results, and they still rule the warranty process with an iron fist.
It’s frustrating, especially 4.5 hours into a 5 hour print, but unfortunately that’s also 3D printing. When printing at volume, occasional failed prints are something we always have to account for.
On my Bambu machines, one thing I’ve seen contribute to this without necessarily triggering a clog error is inconsistent filament diameter. The extruder can end up slipping without the printer immediately realizing it. Interestingly, the X2D seems better at detecting this.
Assuming the filament itself is good, I’d look at retraction and speed and redo the flow dynamics calibration before blaming the printer.
As for Bambu filament… at their price I’ve never actually used it. 
Absolutely and that’s why I stopped buying them
What I am kind of happy though is I did not jumped to H2D/C series. As if you go to their part of the forum you can see the same or bigger and expensive problems if you really try to print high temp and multi-material stuff. For which this machines are supposed to work. Or bambu-die-hard-fans-forbid if you try to print TPU. If you print multi-color figurine and fidgets from PLA and maybe some PETG, and you get good working unit/AMS they are just fine. For me right now Bambu real good products are A1/A1 mini, P1S and maybe P2S. Based on the feedback here and over the internet. All else is too expensive and so many ways to fail.
I can understand that people with good working units, and making money from them. But not sure why they can not understand us, as I am not making any money with this printer and wasting too much time for very simple things, which are supposed to just work?!?!?! Basically if you do not have 2-3 printers or very good unit, you are just stuck. And not everyone can afford spending 2-3-5K EUR/$ for printers.
Filament and cooling profile management are just non-sense complexity and even more.
Kudos they made the warranty expansion 2 years, but main parts like extruder are actually without warranty. They really need to stop with generating more and more models and try to refine whatever they already spawn to the market.
Also I do not like the way Bambu manage known issues on the market. They do not really do recalls. But wait for you to buy the obviously defective series ( for example with AMS 2 PRO not loading filament), then you need to find out the unit does not work ( what a surprise ), then you need to talk to support, they to investigate and to send you new unit. Which is lots of time. Maybe after first 10-20-100 tickets they could do recall to manage this issue, and not hand it over to the customers? I am not sure what is worse they do not do recalls but know for the problem, or they do not have idea which units are affected to recall them … Now this X2D issues start to look very similar. If the issue is in the FW why they replace printers, and the new printer on the same FW level works better?
In general too much wasted time which could be spend printing if they actually had more effort in QA.
I’d personally ask for a P2S - mines an absolute workhorse and not has an issue- I do agree with the Friday afternoon make scenario- it does seem to be a bit pot luck with most of Bambu printers now 
Small update on the replacement:
On September 30 I finally accepted Bambu’s offer to replace my X2D.
Instead of starting the replacement, they replied:
“We will discuss it internally and provide a reasonable solution.”
Maybe that means they’re reviewing the case again and considering a different solution, honestly, I don’t know.
I asked for an update, but apparently October 1–7 is a holiday period in China, so everything is delayed. A little frustrating as an EU customer who purchased from the EU store, but it is what it is.
So for now: replacement accepted, one week later, and I still have no idea what’s happening.
Hopefully I’ll know more after October 7.
Anything new on your case?
Yeah
On October 7, Bambu confirmed the replacement and offered two options: Standard Exchange or Advanced Exchange (with a deposit). I chose the Standard Exchange.
Since I no longer have the original packaging, they arranged to send me a new box and protective padding.
Somehow, we lost another couple of days because they asked me to confirm my address again — the same address they’d already shipped replacement parts to three times.
On October 11, they confirmed the packaging had been shipped.
I’m now waiting for the box, hopefully arriving by Thursday, so I can pack and ship the X2D back before the end of the week.
At least things are finally moving forward. Let’s see how long the actual replacement takes!
