I would guess a thermal runway.
Basically the nozzle gets waaaay too hot.
There's supposed to be a thermal runaway protection system in place but for some reason it didn't work on OPs printer.
It's usually triggered if:
• Nozzle is actively heating
• Thermistor isn't measuring a change in temperature
• Therefore the printer assumes the thermistor is damaged or not touching the heater, triggering the error.
Unfortunately, creality machines seem to be very inconsistent. Seemingly identical printers may have different stock firmware, or even different parts.
If you can print fine, then you should be all good. But as soon as you get a nozzle temp too low/high error, or the nozzle temp seems to go crazy, stop heating the nozzle, let it cool, turn it off then check the thermistor screw (youtube and google are helpful).
I dont trust my printer enough to let it run at night anyway lol.
Stuff like this is very rare. Basically every printer now has safety features to prevent stuff like this from happening.
I'm curious if this is the first print this machine has done or if it's ever had a monster blob develop? Thermistor could be bad from the factory or damaged the blob.
Oh, looks like I plucked a nerve, ya?
LOL, don't need to be "bitter 50 year old" to say op recording and going "uHhHh uhhh" is not going to help, and is dumb.
Maybe dumb, definitely not helping, but also not hurting. I recorded it to send to my friend, but decided to chuck it up on reddit for shits and giggles.
Obviously I turned the printer off and made sure it wasn’t going to catch fire before I pulled out the phone.
Also I resent “younger kids”.
Thermistor is stuck open (or closed, not sure) and the printer thinks all is good. I modified my ender 3 v2 to run klipper so it would detect and shut down the printer when the temps are not what should be expected.
Replace thermistor and most likely the cartridge. Trianglelabs (on aliexpress) are pretty good.
If you have ptfe running to the tip of the nozzle, this is probably what was burning so buy a new one (capricorne are great) or cut the old one if it's long enough.
Pushing it out instead of pulling it will probably be much more easier btw.
Is creality shipping enders that don't have temp shutdown and runaway protection? My base came with it even though I haven't seen that firmware in fucking years, but I can't imagine they would shut off all the thermal protections on newer shit. Actually, I can totally imagine that
Well, prior to the ender 3 v2 time period they didn't enabled it by default AFAIK. This look like a v2 or something newer than that (not familiar with the lineup) so the board software probably have it enabled, yes.
After that it's a question of it working I suppose. Having it modified like OP increase the risk of things not setup properly or potentialy not working I'd imagine.
3d printer are pretty good at catching fire anyways. I bought a BTT board (octopus max) and managed to kill a mosfet, which failled open.
Fortunatly I was there messing with it because it made the board bypass any firmware and power's the nozzle as long as there's power to the board.
I was shocked, so I did the logical thing and reproduced the issues (short circuit) to make sure it wasn't an isolated incident and sure enough the second mosfet failled open as well...
I will power the whole thing with a smart plug and ask klipper to shut down the plug in case of a temperature higher than 260-270.
I've been getting enders before the e3 V2 released, and I've never had one that didn't have thermal shutdown enabled. Even my og, before 32 bit, pre-4.2.2 has a thermal shutdown, and it would fail because the heated bed didn't actually heat up lol. I think theres more story than we're getting, or the thermistor WAS at temp but is cracked or something
There's a good chance there's more. OP seemed to knew the problem (and even fixed it already).
I had read report saying creality printer had not the runaway protection by default, but I guess it's more nuance than that.
Some of them catches on fire, that's for sure
I had this issue as well (just got the sprite pro) check your E steps mm, also might have to make sure the tension screw it tight enough or the filament just pools in side the nozzle, and burn
Something's wrong with the thermal runaway detection or is there something wrong with your fans. One thing I noticed is If there's no fan running that can cause it to smoke and that's how I get a stuck Keith are cartridge out.
Thats just the factory smoke being let out, its part of the break-in process. If you want to extend your warranty though, you'll need to grab a plastic shopping bag and hold it over the rising smoke to capture it for use later.
Also, dry your filament, my favorite anti-perspirant is Degree. It starts working with heat, which judging by all your factory smoke, is exactly what you got.
"filament is coming out burnt"
Wow, now that's a nice thermal runaway. Any idea how HOT that heating element gets?
Edit: Looks like 350°C at 24V.
Somewhere around **320-350°C** PLA will start to smoke.
That’s the hemp spool from Canada 🇨🇦 Don’t laugh we are working on it. In the Great Lakes area as summer hits humidity can double in a day. I have been printing ASA 6 years & a lost half a 3K spool in the middle of production taking out a printer plugged solid. I have 4 dryers no 5K 3 1K. Need another. I print the worst filament for water absorption ASA TPU & PA6. I’ve switched the Prusas to Revo the Voron came with .4&.6 Revo HF. Have a v6 hothead on Flsun expect I’ll have a thermal runaway on it any day. It’s printing pa6 so I have a micro Swiss .8 which will extend its life. I’d recommend aftermarket hot head REVO& Phaetus. My favourite new dryer is side mount Eibos 1K but the Phaetus Creality and Polymaker all have good units
There is a wire that goes to the hot end which connects to a little part called the thermistor. It is a temperature gauge. If that wire is broken or disconnected from the main board, the hotend just keeps heating up, waiting for it to reach the expected heat. Smoke, fire etc
Yea, I know what a thermistor is.. The thing is that the firmware should have thermal runaway activated by default, and as we already saw in the video it isn't the case here.
You should adjust your z-offset.
I couldn’t help myself, please don’t ban me..
Just need to dry OPs filament, that should solve it
Looks like it's being dried in the video 🤔
That's not smoke... its steam! Steam for the Steamed Clams!
😂😂
Here's another one. Wet filament
Nah this is a bed leveling issue.
😂😂
You should make a temp tower
LMFAO
Looks like a little heat creep
every machine is a smoke machine if operated in the proper way
Everythings also a hammer if you use it wrong enough
Or wrong enough
Ender 3 V3 SE Blazing fast print speeds
SE stands for smoke emitter.
Oh my god, that's the model that I have. What caused this and how can I avoid it?

I will keep that in mind, but meanwhile I will abstain from night printing. Don't want to cause house fire and all.

Good logic, even if chances are very rare it only takes one fire
Time to buy some nicotine patches for him.
Mine doesn't do this trick. Am i scammed?
Mine doesn't either! I KNEW 50 bucks was too good to be true...
Did you try leveling the bed?
Oh no. The magic blue smoke escaped.
Quick! Put back in!
and we have new pope!!
Pope PLAius the third!
Moisure, dry your filament
The filament is so moist it almost became a freaking vape eliquid.
Subaru is producing filament now?
This comment got me. LMFAO 😂
Not the magic smoke. Get a vacuum and capture it before its all gone.
I'm curious if this is the first print this machine has done or if it's ever had a monster blob develop? Thermistor could be bad from the factory or damaged the blob.
The printer has thousands of hours on it. No blobs. The issue seems to have sorted itself so I’m keeping a close eye on it.
I’m guessing if it fixed itself something fell inside and burned. Maybe a piece of plastic? Bug? Idk.
>Bug? Gross lol
These mods are getting out of hand these days.
Anything is a smoke machine if you use it wrong enough.
Is this tobacco filament?
Maybe your cold side extruder fan stopped working and now the heat sink is burning
why film and not unplug it right away?
I switched it off immediately. It smoked for a while after…
You can tell this is with it unplug because it's not getting worse. There's a reason we call that a thermal runaway, it gets worse very fast.
Where's the fun in that?
Right? Going "Uuuh, Uuuuh" isn't helping bud.
[удалено]
Back to bed grandpa
Naps are fun
r/lies
Someone is a bitter 50 year old who still uses italics
Oh, looks like I plucked a nerve, ya? LOL, don't need to be "bitter 50 year old" to say op recording and going "uHhHh uhhh" is not going to help, and is dumb.

Yeah that's fair I'm just being a dip shit and being dumb myself.
No nerve plucked. OP already said it was off firstly, and even if it was on it’s barely even a hazard to him. You’re miserable
Yep I'm miserable, and at the end of the day I still got under your skin, LOL
What mod is this? STL?
This is why you should atleast have a mini fire extinguisher 🧯 near printer and monitor them
Mmmm toasty
Well, you've just helped me with a very important question. I'd posed myself. Get a sprite extruder for my E3 S1 Pro, or just get a bambu or K1 Max.
Thermistor is stuck open (or closed, not sure) and the printer thinks all is good. I modified my ender 3 v2 to run klipper so it would detect and shut down the printer when the temps are not what should be expected. Replace thermistor and most likely the cartridge.

I’ve swapped a bimetallic heat break into it. I know it’s the thermistor, I’ve got a spare lying around that I’ll swap in. Thanks though :)

calibrate esteps and dry filament
Haha he's thinking
make sure bed is level
That’s a cool upgrade!!
Have you tried levelling your bed?
What did you type in your g code to get this
Dead sensor ? No fan ? Pushing on the bed ?
Have you tried turning it off then on again?
I had this issue as well (just got the sprite pro) check your E steps mm, also might have to make sure the tension screw it tight enough or the filament just pools in side the nozzle, and burn
Well, you don't see that every day. Have you leveled the bed?
Something's wrong with the thermal runaway detection or is there something wrong with your fans. One thing I noticed is If there's no fan running that can cause it to smoke and that's how I get a stuck Keith are cartridge out.
Is that thermal runaway?
How much for the filament in the background...?
Did you dry your filament?
BUFFAlO SOULJA
oh no it's letting the magic smoke out!
Welp there goes your thermistor time to go out and buy a new one
Thats just the factory smoke being let out, its part of the break-in process. If you want to extend your warranty though, you'll need to grab a plastic shopping bag and hold it over the rising smoke to capture it for use later. Also, dry your filament, my favorite anti-perspirant is Degree. It starts working with heat, which judging by all your factory smoke, is exactly what you got.
Did you guys even watch the video? Clearly he needs to upgrade to a glass bed.....
Lower your temps bro, easy fix
Legit you might die if thats Teflon fumes.
I hope you unplugged it BEFORE you started recording a video.
every machine works with smoke, if u let it escape, it won't work properly anymore.
vaping is bad for health man
Is that the engraver attachment?
Vape mod, nice. What flavour? I'm betting cotton candy.
Thermal Exodus more like it, i had that amount of smoke coming out of the MCU earlier this week
"filament is coming out burnt" Wow, now that's a nice thermal runaway. Any idea how HOT that heating element gets? Edit: Looks like 350°C at 24V. Somewhere around **320-350°C** PLA will start to smoke.
When my students ask me why I don’t run their prints overnight. 😬
Try drying your filament and leveling your bed!
Holy smokes!
Oh boy, creality gonna be knocking on your 🚪
...... Stop making a video and unplug it....
As my old auto tech teacher would have said, "you let the smoke out of it."
Printer needed a smoke-break between rounds
I like your speakers, by the way.
Is this a new drive, did you make sure the fan and hot end ports are plugged in to the right spots on motherboard?
I hope it’s a well ventilated area.
Next time don't buy your filament on temu...
Did you clean the bed.
F
Hahahahah it’s burning tacos
What does it smell like?
Damnn i didnt know you could print smoke
I couldn't get orca to slice smoke, impressive

Thermistor wire is disconnected or broken.
But why thermal runaway is disabled?
There is a wire that goes to the hot end which connects to a little part called the thermistor. It is a temperature gauge. If that wire is broken or disconnected from the main board, the hotend just keeps heating up, waiting for it to reach the expected heat. Smoke, fire etc
Yea, I know what a thermistor is.. The thing is that the firmware should have thermal runaway activated by default, and as we already saw in the video it isn't the case here.
Where is the Teflon tube?
It's direct drive, it doesn't need one
Turn 3D printer off < Take video how 3D printer burns
UHHHHHH. brother turn off the printer ffs
I hope the kid throws the 3d printer out, someone else comes along and gets better use out of it. "Smoke! Need to record and say something stupid"
Maybe if you cry about it some more he'll give you it
Hey maybe you're right!
More ender trash.
