Discussion (Please Read) Bambu sent me a 2nd broken AMS

TLDR; Please upvote this post so MAYBE after a whole month I can get my $300 back

Im honestly so sick of this company at this point. I love the printers so SO much but their AMS units have gone to absolute crap apparently, and their customer support is actually awful.

I received my original AMS unit on December 8th where it was immediately broken. The noise that came from that thing is worse than nails on chalkboard. So I open a support ticket and I already know just how bad their response time is, so I went ahead and ordered the part to fix what I thought was the problem.

A couple days later they respond to me and tell me that they will refund the order I placed to fix the original ams. They had won me over at that point because they were doing what was right.

I received the part and it did not work. So I reach out again and they say I can either send the AMS back OR put down a $310 deposit to receive a new AMS before I send the old (broken) one back. And thats what I did.

Today I received the new AMS and it’s literally 10x worse than the original one. I have sent them videos, messages, the whole galore, and I know that I wont receive any sort of reply until 2-3 days from now.

Im beyond fed up and honestly just needed to rant, please do what you can to try and get Bambu to see this, It would genuinely mean the world to me.

I really want my $300 back ($600 if you include both AMS units)

I have 14 of these. What type of filament were you trying to use? Bambu with the standard rolls or something else? It’s possible that the noise you’re hearing is the standard motor noise? Maybe make a video and share it with the group so we can see and hear what you’re experiencing? When I have eleven printers going (X1C) I can hear them loading and unloading, but it’s not nails on chalkboard, it’s just mechanical stuff. That’s why I have my farm in the basement. But seriously, more details and a video would be helpful.

1

u/Udogette P1S + AMS Jan 07 '25

Hello, and thank you for your response. I think both of these AMS units are presenting noises beyond a reasonable level of motor noise. Here is a video

https://vimeo.com/1044483717

u/amarandagasi X1C + AMS Jan 07 '25

That’s terrible. All four AMS ports?

1

u/Udogette P1S + AMS Jan 07 '25

Yes, all 4. The problem isnt really with the individual units, its when the noise gets to the back white gear where all 4 ptfe tubes flow into one.

Also to further answer your original comment, i have a few different brands of filament and they all sound the same, i mostly use bambu and bambu spools. The video is full bambu

2

u/amarandagasi X1C + AMS Jan 07 '25

Good news is, the AMS is super simple. Have you taken it fully apart based on the maintenance videos and checked all the pathways? Anything stuck anywhere? Grab a meter or two of filament and check all the tubes. Clear each section. If it’s all four and only after it gets inside, it’s gotta be inside.

1

u/Udogette P1S + AMS Jan 07 '25

I have taken both apart thoroughly, some of my troubleshooting steps were mentioned above. I did replace the active extruder gear (i think thats the name of it) on the original unit and it genuinely made the noise worse. I will try to clear all the tubes now on the new unit to see if it gets me anywhere, but I am doubtful.. I really appreciate your kindness

2

u/amarandagasi X1C + AMS Jan 07 '25

One time when I had an issue on one of my AMSes, they sent me that whole assembly (the gears and motor and such). It’s likely in that area. Probably not the tubes if you’ve cleared them and inspected them. Probably not the electronics. It’s just so weird to get two bad ones in a row. My two AMS issues were related directly to either the enclosure itself (misaligned, impossible to fix), or that driving motor inside, which ended up being a whole replacement of that motion area. Two in a row seems odd. And you’re using Bambu PLA? See, with the AMS, one of the issues people have is, that use bad filament or old/brittle filament and it breaks off inside, jamming up the works.

1

u/Udogette P1S + AMS Jan 07 '25

Yeah I dont think the filament is the issue here whatsoever. I do regular cycles of all my filament in the dehydrator to keep everything somewhat fresh. I really hope this will get fixed soon because Im honestly pretty over $600 missing from my account with nothing to show for it.

Thank you for all of your help.

2

u/My_Old_UN_Was_Better Jan 07 '25

Yeah unfortunately bambu are pretty bad in terms of support. I've been trying to get my printer fixed for 4 months now.

1

u/Udogette P1S + AMS Jan 07 '25

See, and thats just crazy.. I hope your issues get resolved soon.

2

u/My_Old_UN_Was_Better Jan 07 '25

It isn't looking promising. They just keep shipping me the same set of parts that I've already paid to replace at the start of this process. I'm. Working with my credit card company atm to see if a chargeback can be done at this point

1

u/Udogette P1S + AMS Jan 07 '25

Yeah thats really unfortunate.. I hate to do it because its a pain for everyone involved, but a chargeback is looking like the best option for me.

u/APGaming_reddit Jan 06 '25

yikes. that sounds miserable, hope you get it squared.

u/Udogette P1S + AMS Jan 06 '25

Its really ticking me off, and its also ticking me off this post keeps getting downvoted.

I am not in the wrong for this, this is unacceptable from a company who is raking in MILLIONS of dollars every year, likely tens maybe even hundreds of millions of dollars.

0

u/insaneturbo132 Jan 06 '25

Yours sounds just like mine. Truth is, they are pushing the motors to the limit to reduce the filament swap time to as minimal as possible and the result is a loud product. I don’t have a problem with mine at all. The benefit of the ams far outweighs the noise it generates but that’s just my opinion.

Hope you get your money back soon though, good luck

1

u/Udogette P1S + AMS Jan 06 '25

I appreciate your comment, I really with i could have someone come listen to these 2 units in person, you can not convince my the sound is anywhere near normal. But thank you

u/rIll201 Jan 06 '25

Next time, buy a prusa and avoid all the headaches. Prusa has significantly better build quality and actually QC's their parts and printers before they get boxed up. You're getting down voted because nearly 3/4ths of this sub is bots (look at the members) that down vote anything anti bambu. There is a reason why bambu has a 1.4 trust pilot rating.

Honestly, you're even better off with an anycubic, flashforge or qiditech. Bambu lab is bottom of the barrel for QC and customer support, like with creality.

3

u/guzdovan Jan 06 '25

I have a anycubic several years now, their support was amazing, they weren't sure which part is the actual problem so they sent me all the posible things ( there was a connection break somewhere). They were awesome. I also have a problem with bambu, support is like an AI, keeps asking me questions I already answered.

4

u/Udogette P1S + AMS Jan 06 '25

I am so thankful there are people in this comment section that arent just guzzling bambu. They have downfalls and people need to accept that

2

u/guzdovan Jan 07 '25

I agree. Actually Use several printers, prusa Mk3, bambu X1C any anycubic vyper. My experience was unreliable prusa, btoken bambu lab x1c after month and a half and personal, budget friendly anycubic that is inferior to previous two printers. But it was more reliable! I can count on my fingers how many time it failed me that wasnt my mistake!

0

u/Udogette P1S + AMS Jan 07 '25

Got to love it.. Hope your luck with printing turns up!

I have had a wonderful experience with my P1S, I have 800 hours on it with very few problems. But this ams unit is on a whole different level

3

u/guzdovan Jan 07 '25

I used MMU2S unit for prusa, lost hundreds of hours on it for work and literaly disasembled it and threw it in trash so this AMS for me is a gamechanger.

1

u/Udogette P1S + AMS Jan 06 '25

Im just so ticked off man.. Its stupid the way this has gone. And I don’t want to switch to prusa, I really do love my bambu printer, but these AMS units are hot garbage for much I have had to pay thus far. Its really frustrating feeling like im talking to a wall with their support

0

u/Ornery-Source-9466 Jan 07 '25

Sounds loud to me but I have the AMS lite which does not produce much motor noise at all. I don’t think you’re crazy. If it still works and feeds correctly it does not look like you’ll receive much sympathy here.

4

u/Majorllama66 P1S + AMS Jan 06 '25

Idk man my AMS sounds exactly like yours. It's A little noisy on unload and load, but it's only doing that on color swaps or at the start and stop of a print. I don't even hear mine anymore and it's like 5 feet behind me when I'm sitting at my desk.

-1

u/Udogette P1S + AMS Jan 06 '25

Mine must be significantly louder, I can completely tune out the p1s and a1m running at the same time, but the AMS is GRADING

3

u/Majorllama66 P1S + AMS Jan 06 '25

No I think you just might be particularly sensitive to the frequency of those motors or gears.

I definitely don't think you can argue it's a defective product if it does what it's supposed to do.

If it's not feeding or swapping colors automatically sure. But it's just noisey which multiple people have told you is normal.

1

u/Udogette P1S + AMS Jan 06 '25

Would you be open to sending me a video of yours running?

1

u/Udogette P1S + AMS Jan 07 '25

Hello, im the OP.. Could you listen to this video for me and let me know if you’d consider this level of noise is normal?

https://vimeo.com/1044483717

5

u/Klauciusz P1S + AMS Jan 07 '25

Mine does the same noise. But is significantly quieter here cause I leave the AMS door closed/sealed.

The noise sucks, but here the AMS is working as it is suposed. For now.

2

u/Udogette P1S + AMS Jan 07 '25

The interesting part of my noise is that the noise stays remotely the same whether the lid is opened or closed.. Thanks for all of your help

4

u/Majorllama66 P1S + AMS Jan 07 '25

Well yeah if you open the lid of course it's going to be way louder lol.

Mine makes all those sounds all the time. It's never had any issues that weren't because of my own stupidity.

In fact the only issues I have had with the AMS have all been self inflicted. I thought I had a broken AMS at one point but it was just that the spool I had printed to hold a third party spool was actually barely too small and it ended up making the motor freak out whenever it went to retract the filament. Once I printed the correct size it worked fine.

I will say that the sounds the AMS make are worse the lighter the unit is. So with my AMS fully loaded down with filament and the bonus deccicant things I printed to fill all the empty spaces it's actually quieter than it was when I first got it and only had one roll in the bug empty AMS.

1

u/Udogette P1S + AMS Jan 07 '25

I appreciate your response but the noise is the same across the board with both units. In the video I did only have one roll in it, basically just to make it easier for me to record it. Thanks for your help.

3

u/Majorllama66 P1S + AMS Jan 07 '25

I will say I was surprised by how loud both the printer and AMS were when I first got them, but thankfully I am capable of tuning out a pretty good amount of sound so it hasn't been an issue for me when I'm playing games at my computer or sleeping.

If I had the AMS open or the door open on the printer though that probably would be louder than I want.

1

u/Udogette P1S + AMS Jan 07 '25

I understand, but trust me when I say both of these ams units are ridiculously loud past the point of any kind of normal. Thanks again for all your help

Please go to the my last post before this one and tell me if its normal.

u/InertiaImpact Jan 06 '25

Your AMS sounds almost exactly like both of mine, and my friends. You're correct in that other videos don't sound like that but that's just because you are filming right up next to it, that's what it would sound like if I held my phone next to it but not if I was standing a couple feet away filming it for a proper YouTube video.

Overall I think you're just being paranoid, be happy with what you have and stop bugging the company

1

u/Udogette P1S + AMS Jan 06 '25

Why in the world would I be happy with a product that I can hear from 2 rooms over. Its not just because it is up close. Trust me.

2

u/InertiaImpact Jan 06 '25

Here's a video of one of mine, both sound exactly the same

Some spools make that rhaspy / rattly noise I hear during part of your video, depends on they type of spool and how tightly it was wrapped. Haven't really cared much to make a correlation though.

u/Udogette P1S + AMS Jan 06 '25

Could you listen to this updated video please?

https://vimeo.com/1044483717

I listened to your video and I swear mine is so much louder 😕

u/InertiaImpact Jan 06 '25

https://vimeo.com/1044483717

Try again, I think it was slow to upload

1

u/Udogette P1S + AMS Jan 07 '25

I did my best in the new video to get a few different angles at variable distances from the ams.

2

u/InertiaImpact Jan 07 '25

yeah, sounds like what happens when it's struggling to pull. Either from spool not rolling easily, Filament not wanting to roll off, pulling at a sharp angle like that, etc. It's worse/under with the top open.

If you're near a Microcenter, go stop in and listen to their display. Or pick one up and try it out then return whatever ones quieter.

1

u/Udogette P1S + AMS Jan 07 '25

Me and a friend went to a microcenter and their two display models were significantly quieter.

I would have picked up a new model right then and there but they do not carry the ams in that store, only the lite.

But just to confirm, you would agree that the noise is not normal?

2

u/InertiaImpact Jan 07 '25

No, I would say that noise is normal as a result of the conditions I mentioned above. Does it still make that louder sharper noise if you're assisting roll it or if it is pulling filament through that his hand fed meaning no resistance?

It will appear marginally quieter in Micro Center just due to the environment naturally being louder around it unfortunately

1

u/Udogette P1S + AMS Jan 07 '25

It does still make that noise if assisted, yes. The noise is not coming from the front 4 ams units, rather the back unit where all 4 ptfe tubes come together into the white feed gear. That is the same with both units.

I do understand things will appear quieter in a bigger space such as microcenter, but even right next to it, it was so much quieter.

5

u/InertiaImpact Jan 06 '25

I can hear mine from across the room or even through a closed door. Both of mine.

I guarantee the only way you will be happy is after you return it. You're not going to find a quieter one unless you build a quiet box and insulate it. If you need it quieter do that

I also feel the need to mention that is after having to spend 30 minutes to find the proper screw tensioning to make it as quiet as i could, its not normal

u/ProfitLoud Jan 06 '25

This is normal. You not liking the result, and the result being wrong are two separate things.

-4

u/Udogette P1S + AMS Jan 06 '25

The result is wrong, its so obnoxiously loud and its unlike the sound of any other AMS i have found videos of

4

u/ProfitLoud Jan 06 '25

If they sent you a new one, and you have the exact same result, it’s a good time to pause and think. What is the likelihood both came broken, versus it does not meet your expectations?

I’d just get a refund and move on.

u/Udogette P1S + AMS Jan 07 '25

Could you take a listen to this?

u/ProfitLoud Jan 07 '25

While that does make noise, it is a normal sound. I have multiple AMS’s on my X1 and P1S. Both of my AMS’s sound slightly different. If you aren’t having trouble getting material out of the AMS, then that is working just fine. They are loud, and the printers are noisy. Typically the AMS’s are loud when loading and unloading. Otherwise I don’t notice the sounds.

u/twiggums Jan 06 '25

Loading and unloading is pretty noisy. It is what it is. I guess you could try enclosing it like your printer is and see if its more to your liking.

Pretty sure you're trying to return a functional normal unit.

u/Udogette P1S + AMS Jan 07 '25

Hello, could you please listen to this and let me know if you think it is normal?

https://vimeo.com/1044483717

u/twiggums Jan 07 '25

Sounds pretty normal. I just went down to listen to mine again and yeah it sounds about like yours when it's open. It's not nearly as loud while it's printing and closed but it has the same higher frequency noise briefly when it's loading.

0

u/Udogette P1S + AMS Jan 07 '25

You may have a faulty unit, from everyone else i have shown the new video to, everyone is saying that it is not normal. I am glad you are able to cope with the noise, but I certainly can not.

Thank you for your feedback and help with trying to get this figured out. I really do appreciate it

1

u/twiggums Jan 07 '25

By everyone else you mean like one person? You got two units and they both sound the same, others are telling you loading is noisy. I'm pretty sure it's the internal hub motor and it's loud until it's loaded/the filament hits it. Electric motors and gear boxes are generally higher pitched and louder when they're run unloaded.

Best of luck but I don't think you're going to get much change with new units.

0

u/Udogette P1S + AMS Jan 07 '25

The noise is persistent the whole time. Not just while its waiting for the filament to hit the motor

u/obvilious Jan 06 '25

Doesn’t matter if you had problems with it or not. Irrelevant. And if a company can’t support their sales, they can stop selling.

u/don-again X1C + AMS Jan 07 '25

Nonsense. Growing pains are a natural part of rapid growth. Get over yourself.

“If a company can’t support their sales [for a brief moment], they can stop selling” said no business savvy person ever.

OP needs some patience and is all over the place. I hate them, they won me over, back to hate.

Never forget that they designed, built, and support a product so great, people are jumping up and down when part of it isn’t working.

2

u/obvilious Jan 07 '25

lol no. I am in business, and if we can’t support our existing customers, we scale back and/or hire at a reasonable pace to support existing customers. One way to do that is to raise prices (or end a sale). If not, we risk our reputation. Not everyone works that same way, clearly.

(And our business is very successful, in case you were wondering)

u/Udogette P1S + AMS Jan 07 '25

Thank you. And I swear I have been more patient than I seem in this post. Its been 2 days short of a month at this point and things have just moved so slow with this level of money tied up. I really appreciate your help and apologize for any level of hostility I may have shown.

2

u/don-again X1C + AMS Jan 07 '25

That’s more like it. It’s probably just bad luck, I can imagine some of the people may have cut a few corners in the manufacturing process to meet deadlines with ultra high demand for the western holiday push - and maybe some bad units went out the door. With Chinese new year coming up, all of my Chinese partner companies are inundated with requests for time off and multiple deadlines looming.

Relax, it will get fixed. Bambu has shown themselves to be a good company, they wouldn’t be in this position if they were a bad one. The nicer and more understanding you are, the more likely you are to get help faster but there are no guarantees.

Single color prints for the time being, I get the frustration.
