100% frustrated

Hello everyone.
I know my post is a bit of a condescending remark and insulting your god, but I still need to vent my frustration. And maybe someone from @BambuLab is reading this.

I’m pretty disappointed with my H2D, but even more so with the support.

Here’s my story:

First of all, my printer is a total lemon.

Delivery day one, it works not right. But as is the case with any new printer, I spent a while trying to find the problem myself. Often the user is the problem.

But after 100 hours of trial and error, I thought, that can’t be right.
I’ve been printing for about 15 years now, have owned over 30 different printers, and have always been quite knowledgeable about the subject matter. Even now, I own 6 other printers, and 5 of them work perfectly. Somone with over 8/9k printing hours.

Here’s the point, which is my own fault. I shouldn’t have messed around here at all; I should have sent the thing back right away. Unfortunately, my two-week return period has already expired.

I was industrial mechatronics engineer, so I’m not completely untalented to work on machines like this.

Nevertheless, I have the following problems:

  • Sometimes extreme z-banding. Totally random. I can print 5 parts with the same settings/filment, and 4 was bad as hell, one ist nice.
  • random Layer shifts
  • Extrusion problems with the left nozzle
  • and a few days ago, the printer started with freezing during printing and then it resumes without checking he do this freeze. Then you can’t do anything with the printer. Pushing on the Display does nothing. This is only for 5-7 seconds. Of course, the nozzle cools down during this time, and the filament logically gets stuck there as well.

And before all the standard answers come up:

  • Yes, I understand how a printer works and can adjust it.
  • My filament is dry.
  • And my filaments are calibrated. Most of the them, even down to the color!

So I grabbed my filament and my file and drove to a friend’s house 30 km away.

Using the file, which I used exactly as it was, and my own filament, his H2D delivered a perfect result. It just looked terrible on mine.

I tried the same thing with several prints. The result was always the same.

So, I went back to Bamboo support.

Here I explained the whole story again. And also that I had tried so many things, which I also explained and told them.

That’s where it all started. A lot of copy-paste replies.
Above all, they suggested exactly what I had already written in my email, which I had already done… Excuse me, what?

Then I was supposed to send them 3mf of the files I had printed, which looked so bad. They wanted to check my settings and give me better ones. :roll_eyes:

I did this several times, but of course, I never received a response. Why bother when the prints turn out absolutely great on another device?

Since support wasn’t helpful at this point, I started disassembling the entire printer, down to the chassis. That took me about 20 hours. During this process, I found a handful of chips in the extruder, which came from production and had already damaged the gears. I also found a large lump of aluminum foil wrapped around the pulley on the lower roller idler.
And no, it wasn’t mine. I don’t have one, I don’t use one, and I don’t need one.
After I told all this stuff to Bambu support. They send me back a link; how to tighten the screws of the heating element. :sob::sob::sob:

I sent this back to Bambu. What do they say: we’ll send you a new extruder. Okay, I thought: let’s try.

It came, swapped, everything was the same. Print quality was the same. Stuck always on the left nozzle.

Then I ran further tests and monitored the nozzle during printing with a calibrated thermal camera from Flir. The nozzles consistently delivered the temperatures they were supposed to deliver. With a tolerance of 4-5°. (Compared to my friends printer)

I also wrote to support about this.

What was the support response: we’ll send you new heating elements…
At this point, it became clear to me: okay, they really don’t read my messages. :man_facepalming:t2:
This whole thing has been going on for months now, and I’m truly at my end with this.

I’ve never had to do anything like this before, but next week will be my first trip to a lawyer to review my options. I want a new printer or my money back.

I’m just frustrated because my A1, which cost €2,000 less, produces better prints…

Of course, I realize that there are plenty of H2D printers that work perfectly.

This isn’t a “don’t buy this printer” post.

This is a “I’d just like to have one that works” post. :person_shrugging:t2:

I hope this is somehow understandable.

I feel for you.

Do not worry about the sycophants that can’t see past their own bias.

Your experience is not invalided by them.

I hope this gets resolved quickly.

Have you considered getting your payment provider involved? They can refund you based on the product failures from the delivery point.

This depends on the country in which you live and your payment providers protections.

I live in Germany, and unfortunately, it’s not that easy here. It involves a lengthy process.

But if there’s no other option, I guess I’ll have to take this one.

I have my first appointment with a lawyer tomorrow for advice.

Thank you for sharing your detailed experience — it truly sounds frustrating, and I can understand how discouraging this must be.

Just to make sure we’re not missing something obvious:
Have you already updated the firmware to the latest version and re-run the full calibration routine?
Also, could you let us know which firmware version your printer is currently running?

No problem.

I tested all the things with EVERY firmware.

Back and forth in all variations….

And every time I calibrated it fully. Including heated plate and vision encoder.

At the moment I run the latest .04.

I’ve been holding back on purchasing an H2D due to the many issues aired on here, I have the X1C which has worked quite well over the last year or so.

@Micha.S story has put the last nail in the coffin were I’m concerned, more so the response from BL support, I just cannot accept that a multimillion $ company would be so loath to provide a customer with a replacement machine and so loath to customer satisfaction as to copy and paste correspondence.

Just saying… :thinking:
I’d already decided that should I ever purchase an H2D which I was holding off for 18 months in order to see customer feedback, if the delivery of my purchase has even the slightest dent, scratch or rip to the outer box, I’ll reject it outright at the door as damaged.

I’m not being difficult as I’ve had deliveries of large household items that were damaged and was expected to accept because it can all be dealt with later…

The way I see it now is like this, my money has paid for the item and it’s packaging, so why accept the delivery if it’s not perfectly presented without any outward signs of damage?

Anyway @Micha.S, I hope you’re able to resolve your predicament in which you’re an unwilling passenger…

Good luck… :crossed_fingers:

Thank you.

And yes; I feel this.
Got a A1, Mini, P1S, X1C and H2D. 4 of them works perfekt. Combined science over 10k print hours.

So feel free to pick the lemon….

This is the thing. After so much messing aorund, I doubt BL is obligated to give you a new printer. They may, but not obligated. Good luck.

ps. If they do give you a new one or refund, let us know. We can use this as an example next time when asking for a new printer.

This is typical bambu support behavior. Some people have speculated the reason they only read the last message is because they need to hand translate or click some button to translate each message, so they only read the last one.

If it was feasible for you, yes you should have.

The two week return period means “return and refund”.

You have 30 days to return it and get a complete replacement for “critical failures or manufacturing defects”.

In the EU, Bambu Lab offers a 2 year repair warranty. It is expected that you are able to replace any consumable part in the printer yourself, but beyond that you should leave those repairs to them. Next suggestion they make that involves anything beyond a consumable part just tell them they are welcome to try replacing that in their repair facility.

Of course you have to. I’m covered by the warranty.

And in Germany, there’s also a separate warranty period for two years. This is regulated by the state here. And the burden of proof only shifts after twelve months.

In other words, in the first twelve months, you have to prove that the defect didn’t exist upon delivery.

11

I’m not familiar with German law, but I suspect that is the minimum warranty a manufacturer must offer, it doesn’t limit them to those terms.

Reading the Bambu Lab warranty, it simply offers a 2 year warranty, there is no “burden of proof” shifting. In other words the bambu warranty is in addition to the statutory warranty.

12

That’s true. But if a retailer sells in Germany, they have to comply with the rules that apply here. And they state:

After the third (actually even after the second) unsuccessful repair attempt, this also applies to repairs carried out on instructions, the customer has the right to cancel. In other words, I can demand a new printer or my money back.

But this isn’t easy at all, because, as I said, the responses to my messages are just nonsense, and most of it is ignored.

13

Yes. Normally Bambu need to react here. But they don’t.

14

You also have up to six years to make the claim, although in this circumstance, my mentioning this is for information only about the law, I do not expect you to wait any longer.

The U.K. has the same rules.

If that’s the case, why bother writing this post and announcing that you are going to see a lawyer though. You could have just gotten a new printer or refund without a fuss.

Anyway, do let us know how it comes out so we can use as an example. I have heard much about (not the same as truely know :slight_smile: the laws in EU, but here in the US, what we have is not bad either. I have returned things, including two printers, without a fuss. I don’t mess around. If something doesn’t feel right, I will return it and get a replacement or a refund.

16

Did you save the logs from each firmware version and also record the failures?

I’m asking because this can really help support handle your case faster — especially since they’re probably not native English speakers and clear documentation makes a big difference.

17

@DWdesigns Are you joking, or did you simply not read my text?

If they don’t respond to my texts and requests, I could be right for a long time.

18

@L0rdS474n Yes. And sent multiple to Bambu.

That’s really strange—every time I’ve provided a clear explanation along with a video, they’ve always started working on a solution very quickly.

This is my first contact with support in three years.

Otherwise, I’ve always been able to solve everything myself.

But to me, it feels like I’ve been given the apprenticeship.
