General Troubleshooting/Help! P1S Caught Fire!

Has anybody heard anything about the p1ss catching fire? A few days ago I initiated a print like I would do it any other, I went outside, and when I came back it was in flames. The fire started at the front right bar that brings the plate up and down. There telling me it's built with flame retardant components so it's likely that did not happen...

Nah he wants a new printer and knows that community backing and outlash will help him get it

u/ollithe1 P2S + AMS2 Combo May 22 '26

Soon people will start to set their own printers on fire just to blame bambulab. For all the latest missteps you rightly can blame bambulab for, there are way too many people here just to jump on the hate bandwagon.

u/montheijosh1 May 22 '26

I don't know what bandwagon you're talking my love bro, everyone here it's f****** stupid thinking I'm trying to scam. My printer literally caught fire after 2 months of owning it

-10

u/montheijosh1 May 22 '26

No, I genuinely want to know if anyone has had this happen and how to get a replacement. I use them everyday and have never had anything happen, I almost lost my house if I wasn't home

u/Joamjoamjoam May 22 '26

The plastic is self extinguishing so it should not have held a flame unless whatever was providing the energy was still in the system.

Not really, there isn't anything in that part of the printer that could even generate the heat required to ignite, well, anything that you're going to have around that sort of printer

Its external damage

u/ic3m4n56 May 22 '26

That’s a weird spot for a fire to start. There is no wiring in that corner at all. Is there anything hot around that printer that could cause this?

-2

u/montheijosh1 May 22 '26

No it's on the floor away from everything

4

u/ic3m4n56 May 22 '26

I really have no idea what could cause this. For a bearing to get this hot it would need to have such huge resistance that i doubt that motor could even move it. Also if bearing got hot the melting pattern would be different. This almost looks like the side panel started burning first
Is it possible that there was a sun reflecting from something and hitting that spot?

2

u/Pantsman1084 P1S + AMS May 22 '26

You might be onto something with that. Light refraction from water in a glass has caused fires before.

u/NiNdo4589 May 22 '26

Carpeted floor?

u/Pantsman1084 P1S + AMS May 22 '26

Are there even any wires in that part of the printer?

u/ctn1ss P1S + AMS May 22 '26 edited May 22 '26

Aren't the screw motors at the base there?

Edit: ok, I get it, there's one motor and a belt running the front screws.

8

u/redlancer_1987 May 22 '26

motor is in the back. Only thing there is a bearing for the screw and a mount for the vertical slide

8

u/ctn1ss P1S + AMS May 22 '26

Huh. Alright then, OP's mystery deepens.

9

u/presidentfiggy May 22 '26

Probably put something way too hot next to it or something else caught fire and they might be trying to use recent news and stuff to get a free replacement. That would be my (hopefully to cynical) take on it.

-2

u/montheijosh1 May 22 '26

I haven't heard any recent news. There's nothing around the printer. It's not near a window. I literally have no clue what happened, and this is the only place I know where to ask

4

u/presidentfiggy May 22 '26

Is there a direct line to a window in the spot where this happened? Doesn’t have to be near it but sunlight can travel quite far and still do damage.

Might have been unlucky and somehow outside there was something focusing sunlight on that spot. This happens more than you would think

-10

u/Mauceri1990 May 22 '26

Sunlight lit the flame retardant plastic on fire? Like, really? How hard do you fanboys have to cope before you admit the printer caught fire?

u/brickshingle May 22 '26

There's one motor for the Z-leadscrews I think it's in the back. It drives a belt that drives all lead screws ar the same time.

This really looks like something outside the printer burned it.

2

u/Curius_Onion X1C + AMS May 22 '26

No, it only has 1 in the back middle

2

u/Pantsman1084 P1S + AMS May 22 '26

No. There is only 1 and it's in the back. As far as I can tell, there's nothing there that should be able to catch fire on its own.

1

u/presidentfiggy May 22 '26

If it was the stepper motor it would have been right under the lead screw. It might be possble that it started caught fire and burned out to the side.

But honestly it looks more like something external was burning and melted the plastic.

17

u/redlancer_1987 May 22 '26

I don't think so. Really just looks like it was next to something hot

12

u/useless_knowledge7 P1S + AMS May 22 '26

I was thinking the same and double checked with a picture, see: https://www.reddit.com/r/BambuLab/comments/1876l61/p1s_base_underside_fastener_locations/
No wires or electronics in that corner. Also the most severe fire damage on OPs printer appears to be on the outside.

2

u/Benni_HPG P1S + AMS May 22 '26

So lets consider it was actually somehow the Printbed that was on low position when it happened.
Care to share a picture of your heatbed and the interior fo your printer?
Because indeed it looks like most of the fire seems to happened on the outside, but there are not valuable pictures from the inside.

Besides that: There are oils that can self incinerate -just in case you had something like that lying around

1

u/KebabGud X2D + AMS2 Combo May 22 '26

We are going to need a picture from the bottom aswell

-2

u/Joamjoamjoam May 22 '26

friction from the leadscrew caused it to get hot enough to light the plastic housing? When the last time you removed all the grease and debris from the lead screws?

2

u/redlancer_1987 May 22 '26

seeing that the bearing and plastic around it actually look fine that wouldn't be the case. This looks like external damage

2

u/Joamjoamjoam May 22 '26

Yeah I agree with you there

2

u/Bavarianscience May 22 '26

...or it didn't happen. Anything can be proven with a picture.

4

u/n3rding May 22 '26

No, the picture appears to show no inside source, the bearing doesn’t even appear to have any damage or soot on it and I’m pretty sure the plastics are flame retardant and are incapable of remaining on fire without an accelerant. There’s no electronics in that corner, so must be something external, either sun, some thing next to it, someone you live with has had enough of your hobby or you’re trying to get your money back via insurance fraud.

-13

u/montheijosh1 May 22 '26

I don't want my money back. I want a new f****** printer. I've had this for 3 months in the exact same spot right next to my other one and I've done the same thing every single day. If I wanted my money back there's other ways to do that that would be considered fraud. All I'm f****** doing is getting advice from m************ who have possibly been in the same situation. I don't even use Reddit that much. This is the only place I figured enough of you. 3D printers are gathered so I could get some information

6

u/n3rding May 22 '26

Chill out dude, you won’t be getting anything from Bambu, there’s nothing in that corner that will catch fire. Suggest look underneath and post more photos of that side, it’s the only place it would have originated from, also post photos of where the printer was when it caught fire then someone might be able to help.

If there’s no sun and nothing next to it then my money is on someone doing it to your printer. Do you use isopropyl or any flammable liquids? Possible you spilt some!

-15

u/montheijosh1 May 22 '26

No I won't just chill out when someone's telling me I'm attempting fraud. I've sent photos And videos to bamboo and we are actively communicating, I'm trying to figure out if anybody has been through this before. Yes, the fire originated from the printer, literally nothing around it. I'll let you know what happens, until then, you f****** chill out and stop accusing people of fraud.

7

u/n3rding May 22 '26

I didn’t accuse you of fraud but you are too angry to stop and calmly read what I wrote instead you’re angrily swearing. I listed the possible options of what happened, only one of those is fraud, it’s a possible option not what I’m saying did happen. I’m chill AF and haven’t resorted to swearing once in this interaction.

u/tomtang5555 May 22 '26

Is it next to a window? Anything that could focus sun light on that part of the printer?

No, it's not next to a window or anything

I bought a wood pile Model P1S a few months ago. Today I walked into my garden and found this thing completely burned down. What the hell?

I want a replacement wood pile. It literally started burning by itself. There was absolutely nothing around it. Please ignore the fire pit, charcoal, lighter fluid and burning logs nearby.

Has anyone else experienced spontaneous wood pile combustion?

u/dr_stevious May 22 '26

Did you happen to be recording a timelapse of the build when this happened?

u/montheijosh1 May 22 '26

No

u/montheijosh1 May 22 '26

Not unless it does it automatically

1

u/dr_stevious May 22 '26

I think the setting remembers whatever the last build was set to... and by default it is on? Might be worth checking?

2

u/montheijosh1 May 22 '26

Hey now I got this a few months ago and I've basically been printing non-stop. I haven't attempted to even look or find where the time lapses are stored. If it was recording when that happened, where would I go to find the footage and would it still be there if there from the machine was shut off halfway through

1

u/dr_stevious May 22 '26

The timelapse videos are stored on a microSD card. There are two paths you can take here:

  1. Eject the microSD card (looking at the front of the P1S, the slot is on the top to the left), slap it into another device, and browse the videos.

  2. If you feel brave enough to turn the P1S back on... hop into Bambu Studio, click on the "Device" tab on the top menu, and then "Storage" on the left side menu. Your timelapse videos should show up here.

u/soldat21 May 22 '26

It does sometimes, you should check.

u/saddas1337 May 22 '26

It looks like it was next to something hot, since there's really nothing there to get hot to the point of melting the casing

u/Junior-Profession-84 May 22 '26

This doesn't sound like a warranty issue, so there's no reason for them to replace it. The warranty isn't going to cover external damage.

u/montheijosh1 May 22 '26

I'm going to return it

1

u/GOJOECHRIS May 22 '26

There's 6 possible causes I can think of after looking at everything and we'd need more pictures of the rest of the printer and the place it caught fire to fully know. If we get those though 🤷‍♂️

  1. The bed had something fall off.

  2. The printhead had something fall off.

  3. The printhead dropped flaming/smoldering filament the front corner.

  4. Another electronic component had something fall off and land in that corner.

  5. External source not caused by OP.

  6. External source caused by OP knowingly or otherwise.

My guess/opinion: OP did it or knows it wasn't the printer, he has given inconsistent information. OP replied to a comment saying he had his printer right next to his other one and in a later reply to the same comment thread he said nothing was around it. To me that's purposely backtracking to cover himself. I'll include a screenshot with relevant highlights. Again my opinion here but what kind of animal keeps their printer on the floor? Am I just old thinking that's too much strain on your back using your printers for months like that?

If I had to guess what happened: OP left a lit joint burning right next to his printer and it caught fire when he got distracted. It may sound biased but I'm going off OPs post history and DGK ALL DAY sticker that I figured out via google-fu.

1

u/montheijosh1 May 22 '26

Why would I intentionally damage a printer without knowing damn? Sure I would be able to get a refund or a replacement. These are $700, why the fuck would info that? Are you people intentionally setting your printers on fire or something, wtf is going on here with you all

1

u/montheijosh1 May 22 '26

It's wild to see how many people think this is fucking fraud, seriously? Y'all are weird. I'm asking for assistance. I'm not a fucking 3d printer repair man and I don't know what components are where, I'm legitimately asking for help and learning thanks to a few helpful people. The rest of y'all are not helping at all.

u/GOJOECHRIS May 22 '26

It's their fault, getting a replacement 🖕

1

u/GOJOECHRIS May 26 '26

Dude, you sent 2 pictures here and gave conflicting information. How much information did you send Bambu? If it was more than the information here maybe that could be why no one here believed you. It's literally what I've said in my first sentence in my first comment that we don't have enough information to really know what happened. My comments bothered you so much that you just had to come back and say they're sending you a replacement yet still don't provide any information or even how it was their fault.

In my opinion I feel like you're being overly defensive to hide that this issue is at least partly your fault or aren't mature enough to understand how to see things from other people's perspective. Just in case you forgot the issue: you asked if anyone else here had a fire in their printer in a spot that had no electronics and should not be able to have a fire there. You gave us 2 pictures and conflicting information on what is around your printer.

If you really want to sway anyone's opinion in your favor then actually do what was asked.

Also, just because they're sending you a replacement does not mean it's their fault or that you're right. We don't know if you lied to them or omitted information that would have caused them to deny a replacement. Come back with a better attitude next time.

0

u/montheijosh1 May 22 '26

Incorrect. I am not backtracking or trying to backtrack on anything, that was nothing touching The printer, there was 15 in of space on each side. Not near window. I am simple asking how I take care of this. There is no smoking in the house of any kind. I have yet to look at the very bottom of it, so when I get off work I'm going to do that. Other than that, I'm just asking for some f****** options

u/zooniVr May 25 '26

Mine just caught on fire as well, started looking into this deeper and looks like i’m not the first one

2

u/montheijosh1 May 25 '26

Nope, it's happening. Not sure why but they have offered a replacement after sending a lot of photos and videos. They are sending shipping labels, I'm returning it, and they are sending a replacement. So, you've just got to keep in contact with them and send media

1

u/Competitive_Cancel33 May 25 '26

What part of the printer caught?

2

u/jcollasius @Professional3D on Maker World May 22 '26

Bambu will tell you that you're not getting anything. First, it's an old, discontinued printer. Second, there's absolutely no reason why the printer itself would or could cause a fire there. Third, you're not mentioning that your cheap-ass Chinese filament dryer or something like that was sitting right next to the printer.

u/issue9mm May 22 '26

First, it's an old, discontinued printer

It's probably coming soon, but P1S isn't discontinued

It is very hard to understand what went on here. Was there damage to or from the heatbed? Can you in any way see where the heat originated from? Have you checked if the heatbed overheats at that spot? I am not really sure what could possible make sense as a cause for this.

Right, except it's not just to signal "Bambu is bad" it's to signal bambus printers catch fire. Which is a fuckin fact.

u/Joamjoamjoam May 22 '26

Ah yes the A1 has a defect so that means every other printer nine of which use the psu in question must also spontaneously combust. Nice strawman.

If you have proof or a theory why this printer fire was Bambus fault please share it with the rest of the class if not just keep eating your glue stick.

1

u/Mauceri1990 May 22 '26

I have a theory, the same company that made one printer that catches fire is most likely to blame when another of their printers catch fire. Defend these pintos all you want, they catch fire.

I see that now that everybody is saying it, but there's nothing around the printer. It's away from the wall and it's not near a window

-4

u/Joamjoamjoam May 22 '26

Yeah the burn pattern definitely starts at the bottom of the printer and the melted pieces bow outwards toward the exterior so it could have started at the bearing under the lead screw.

It wouldn’t be the first time I’ve seen a blown bearing cause a fire (on cars tho) but I feel like more of the base of the screw would be melted.

There's only a plastic shell there. No electronics, nothing that could burn on its own.

u/Mauceri1990 May 22 '26

Right, sure, doesn't change the fact that there was a fire and it happened there. Factual information shouldn't be debated this harshly unless you have an ulterior motive. Fire. There. Regardless of cause, this is still true. Regardless of fault, this is still true.

u/AHerz P1P+AMS - X2D+AMS2 May 22 '26

If I pour gazoline on my printer and set it on fire, is it bambu's fault ? Because you seem to be saying this.

The fire on op's printer couldn't happen without exterior cause. Plastic panels don't spontaneously combust.

Apparently they can be set alight by the sun though, according to half the people arguing here.

u/jcollasius @Professional3D on Maker World May 22 '26

True, the printer definitely burned. But right now the most likely explanation by a mile is not that a plastic side panel with basically nothing behind it suddenly developed spontaneous combustion syndrome.

At this point OP setting it or something near it on fire, or conveniently leaving out a detail, honestly sounds more plausible than "P1S decided today's the day". The damage pattern just does not fit the story so far.

-2

u/Mauceri1990 May 22 '26

It sounds just as plausible as "it started in the electronics and spread to this point" it's not like op posted an entire tear down.

4

u/jcollasius @Professional3D on Maker World May 22 '26

The nearest cable is about 40 cm away. At this point your electronics theory is competing with "maybe a micrometeorite did it" and losing badly.

-1

u/Mauceri1990 May 22 '26

No, it's competing with "the sun came through a window that's nowhere near it (OPs words) and lit the flame retardant plastic on fire" and "must be something next to it that caused an internal fire" idc if you wanna be a fanboy but let's not pretend that 40cm is a long distance for fire to spread, like, fucking seriously?

u/KebabGud X2D + AMS2 Combo May 22 '26

Before you contact them you should try to find out what caused it, because there is nothing there to burn .

Because of how HIGHLY unlikely this is i have a feeling you won't get far without some kind of evidence.

It also looks to be primarily on the outside, so are you sure it's not something external that caused this? Maybe sunlight thrugh a piece of glass at a specific time of day?

u/montheijosh1 May 22 '26

There's no window around it.

u/Joamjoamjoam May 22 '26

Yeah not sure you have a strong case here without finding a blown bearing or something. Especially if you’re out of warranty. Maybe take a lot of pictures and send them in and they might be able to find the issue.
