What kind of question is that? No it’s not obvious especially for a machine you didn’t not build and more than that, you’ve only watched in couple halfasses video reviews where the only thing they do is gloss over how pretty it is…from afar. Even if they show something it’s for mere seconds and in no way enough to be able to say whether your machine is assembled as should. We are the consumers, not the Quality Assurance employees, get that idea out of your head.
A straight one. It looked obvious, so I asked. I then followed up my post with a reply after I realised it happened a few days later. I don’t see how that is a problem.
You really do seem to have an issue with everyone and everything. Are you okay? Do you need a hug or something?
Read this , cause this troll keeps flagging it.
I believe it’s important for everyone to recognize that when you purchase a brand-new machine—especially one advertised as pre-calibrated and tested—you should rightfully expect it to function properly straight out of the box, without needing to second-guess its assembly or configuration.
Insisting that users should know exactly how a correctly assembled unit should look or behave, despite never having seen it before, seems rather unfair and frankly misplaced. If the manufacturer’s claims about rigorous pre-shipping calibration are to be believed, then users shouldn’t have to “check for themselves” or anticipate errors—they should be able to power it on with full confidence that it will simply work, as promised.
Brushing off legitimate concerns by suggesting they stem from user error or lack of inspection often does more to excuse poor quality control than to help anyone. It’s a perspective that tends to benefit the manufacturer more than the customer, and it’s disappointing when fellow users adopt it.
All that being said, you cant avoid fanboys just drooling over forums, trying to hide real issues so their favorite company doesnt look bad.
Problem is that there is a long logistical proces from the quality inspection in the factory until it is unpacked and plugged in at the customer.
If you read this community, you find enough examples of packaging heavily damaged on arrival and glass doors or top panels crushed on arrival.
Then there are the cases that the packaging is visually intact, but the rough handling has caused severe misalignment of the assembly.
And then there are the cases that people don’t follow the unpacking process and switch on the printer while not have removed all the transport fixations.
And I can assure you that not everyone dares to admit that they made mistakes. Removing stuff after they powered on their printer might already have caused severe damage or at the least misalignment.
And not all is within the control of Bambu Labs.
And yes, there are for sure also bad machines leaving the factory.
Biggest problem here is that you can not quantify anything from the responses here, because all the happy customers don’t come here to say how happy they are.
And you don’t know how many of those are already delivered to end customers.
You are right, it should be packed better. Also, if people are unboxing it incorrectly, and bambu wants to be the brand for new users, it should be straight forward enough for those new users. Lastly, there are enough bambu apologists in this forum to counteract any legitimate issues people have. Not sure why I keep reading that only negative comments make it into the forum when we have a crew of people that post nonstop to counteract any negative comment made. Usually blaming everything but the manufacturing. But, when its a different brand, they suddenly see all issues as a manufacturing issued and blame those brands 100%
I am one of the happier customers I have little to no issues with the printer itself (probably except from the part where the cutter stopper is too loud). But I had my previous machines with really bad QC as well, e.g., my X1C had its camera sensor fell off from the lens; my a1 mini had its hotend heater assembly screws loose with merely ~100hrs of printing (and the samething happened on the H2D, except that this time I’m well prepared and know I should tighten it)
I am unsure why it happened, but my nozzle wiper bent and got caught on the poop chute metal piece. now it’s all scratched up, and caused a whole bunch of chaos. It has caused the yellow wiper/purge jaws to get stuck, and upon opening it, the springs jumped out and I have no idea what position they were in. Can anyone shed some light on where the springs go and if there are any tricks to not wanting to get a refund on this machine?
Thanks for this tutorial! Not sure, if that was from factory, but today i found my wiper as shown in wrong place. Your post helped me to fix problem. Don’t know how it survive for all that time.
Exactly my experience! Three months and hundreds of hours of near perfect printing, and this just happened… Horrible grinding noises, and a trashed nozzle blocker and scratch marks nearly identical to the ones seen in the original post.
those marks that I see going upward and the fact that they come out of the internal supports !!! I have a question is not that the plate you put it wrong and when it lifted up it bumped making the purge holder go up ?
Interesting. I got my H2D right after it was released. After it arrived I checked to make sure everything was in place. About a month later I checked for this issue and it was seated properly. Today I heard a lou d bang and saw the wiper gone. 888 hours and this just happened. What I think happened is that the edge of the build plate catches the edge of the wiper module, lifting it up and pulling those tabs forward. You can tell because I have scratches on the left corner like the OP has in thier picture. Dont think its a quality issue more than incorrectly placing the build plate on the platform.
Thanks for posting! I stumbled across your post because my H2D failed It’s initial calibration on start up out of the box. Within the first minute of calibration the nozzle wiping pad came tumbling off. I initially thought it had come loose in shipping and just needed to be reseated.
I should’ve stopped the calibration at that point but foolishly let it continue. While it continued the calibration, I started searching for how to reinsert the nozzle wiper pad correctly — I wanted to make sure I re-inserted it in the correct orientation. That’s when I stumbled across this post. While it was still in its calibration process, I grabbed a flashlight and took a peek and sure enough my purge wiper assembly was installed incorrectly…just as your pictures showed.
Right at the time I discovered this, the calibration failed in the last minute when it got stuck/jammed on the purge wiper assembly.
I was able to carefully move the head out of the way and remove and reinstall the purge wiper assembly correctly. I’ve since printed several items and not had any issues.
Thank you again for your post!
I’ve also had the same problem: for some reason, the nozzle hits the purge station housing and makes a loud noise, but it often pops the nozzle’s cleaning rubber, or simply gets stuck and won’t come out.
I’ve disassembled the purge station, adjusted the springs, and still sometimes the metal part won’t retract.
In my case, the tab was out and the rear screws holding the purge station were in the lower position (they should be at the top!). I applied the solution proposed here and it worked, but the purge station box is already scratched and I will ask Bambu for a free replacement, because I think it is a quality control or design problem that cannot be accepted in a printer of this price.
Let’s hope they fix it because it’s a shame that such an expensive machine has these problems right out of the box.
Had a similar problem this morning - loud, expensive noise and temperature errors from the left nozzle. Inspection shows wiring had been ripped off the nozzle. Checked after reading this post and I have the same issue.
Raised a ticket and now waiting (printer is 3 weeks old and has done 130 hours until the wiper failure last night)
Update: New left heater assembly arrived and fitted without major drama (wiki videos provide enough detail)
Printer back in action
Had my H2D printer 2 weeks ago and thanks for the post. I checked mine and it seems to be installed correctly from the factory but it was worth double checking.
Thank you for this post - 686 hours of printing - no problem. Then all of a sudden it started making horrible noises and bent the flow blocker. I then noticed that it was locking the head behind the purge wiper mechanism.
I also had the exact same problem: the nozzle, base, and purge station were damaged, but Bambu replaced them free of charge, but it took too much time and effort to fix. If it’s a design flaw, the customer shouldn’t have to pay for it, and if it’s a problem with the inspection chain, Bambu needs to improve that aspect. Now I have doubts about the future tool changer, whether it will bring more problems than improvements…Who knows!
Printing for months just fine. Then today - giant chonking noise, rubber while ejected and print head stuck behind the wipe mechanism. Found this post. Yup the tabs WERE shown just how the OP showed them. 5 minute removal and replacement and it seems to be fixed (1 print so far). Thanks to the OP for such a detailed posting.
Same experience here, loud noise, dislodged wiper and an error about the left side nozzle temperature.
Confirmed with visual inspection that there was damage to the hot end wiring.
Replaced the hot end, and first print ripped the hot end thermistor wiring again during the purge cycle…
Finally found this thread, and realised that after 6 solid months of use, the assembly is incorrect,
Corrected assembly, fixed thermistor wiring, and it has started working again.
- I can now print again without the printer destroying itself.
