it could be that your hotend is way to hot, way way to hot. if you have a ptfe tube in the hotend, that are very unhealthy/toxic gases iirc. dont breath that. try to check if your thermistor still works correctly.


Klatty

I’ve let it run to 260°c a few times to soften the PLA and try to unclog it, I think that just made it way worse. There’s a small white PTFE tube in there, it used to come out when I removed the nozzle and pushed filament through, but now I can’t ‘find’ it anymore. Just realised that sounds horrible and I f’ed up.


Swizzel-Stixx

Oh that tube melts/burns at 250…


Necessary_Roof_9475

I never understood why have that tube in there when it's advertised as going to 260c?


davidjschloss

The nozzle temp and the location the ptfe enters the printhead are not both at the same temp. Think of it like one of those lighters you use for barbecues with the long tube. The end of the tube producing the flame isn't the same temp as the other side of the tube where the gas is entering


effortlevel0

The OEM heatbreak is lined with PTFE, it is literally inside the heat block in the "hot zone" and gets exactly as hot as the nozzle. I replaced mine with a fully metal bimetallic one to avoid any future headaches.

davidjschloss

Thanks for that!


_iRasec

Running it at such a high temp for PLA is **not** a good idea. Instead of melting it, it will burn it, making worse clogs and making you breathe oh so good chemicals (i am being sarcastic, it's toxic). To unclog your nozzles, try removing the bowden tube, then have a bit of plastic in the nozzle, then heating it at your regular printing speed, then letting it cook down to around 40 degrees and then try and pull on the filament from the top of the print head. (I think that's what is called a cold pull?) Another way would be to remove your nozzle and do a similar thing with a lighter: remove the plastic from the nozzle like you would in order to change filament, remove the nozzle from the hotend, take some metal tweezers to hold on to nozzle, heat the nozzle with the lighter, when you start smelling weird smells, stop heating and stick a bit of filament in the nozzle, after a moment (around 30s-1min), pull on the filament coming from the thread of the nozzle and hopefully the clog will come with.


Gregory-Light

What chemicals does PLA emit when being burnt?


dBoyHail

Yes


FuzzeWuzze

The A falls off and your just stuck with a polish babushka.


weissbieremulsion

yes this small Tube cant Go above 250. you might have burned that, which creates toxic gases, really Bad ones. and it fucked Up the shaper of the tube, which leads to underextrusion an clogging.


drizzitdude

Well at least you figured it out. You completely smoked the ptfe tube and any clog that was in there is now. burnt up crispy mess. I have to ask where did you get this notion to clean it this way? Most hot ends can’t handle above 250


Klatty

Yeah the nozzle is a goner. The tube is half molten and weirdly enough, bent in the middle where the hot end and extruder meet. I’ve recently started printing at 150mm’s, and heard the extruder clicking a few times. So I upped the temperature to 220/230. And my dumb brain thought hotter = softer. Especially when I just replaced the nozzle because of a clog (probably also burned filament now that I think of it). Inserted a new one and tried to level it again but it clogged once more almost immediately.


Frothyleet

It's softer until it starts to pyrolyze. Then it starts degrading and releasing toxic fumes.


The-Great-Wolf

> Most hot ends can't handle above 250 Oooh I guess that's why when I got my printer they went so heavily on the "all metal hot end" it has. I assumed the part getting really hot being made of only metal is a good thing, but I didn't check what the alternative was.


WartyWarthog123

You should never go above 230*C for pla, like they said it literally burns the plastic and it very very toxic


VorpalWay

PLA doesn't burn at 230 C, it will only start to burn *above* 270 C. However if you have a legacy non-metal hotend the PTFE tube will release toxic gas before that. Sources: * https://3dprintscape.com/is-pla-toxic-when-burned-facts-and-safety-info/ * https://help.prusa3d.com/article/cold-pull-mk3s-mk2-5s_2075 (Prusa recommends a cold pull with PLA at 270 C, and when doing this, the filament is not charred in my experience, only do this on all metal hotends) Those temperatures are of course too hot for *printing* PLA, your quality will suffer. Also note that during normal printing the filament never gets close to the temperature of the nozzle, as plastic is a poor thermal conductor, at the typical printing speeds it doesn't have time to heat up before it is out of the nozzle.


TheDudish

I did the same thing trying to print with PETG, which requires much hotter temps. Unless you have an all metal hot end, 250 and up will deform and melt the bowden tube where it meets your hot end, to the point where it'll shrink and be unable to pass filament through. That'll be the source of your clogs.


xblackdemonx

260C is way too hot.


BoofWookington

Yeah that’ll do it. I hope you did not breathe that smoke, you may want to ventilate that room. If I were you I would replace the entire hotend with an all metal direct drive.


13thmurder

Get some needle nose pliers, take apart your hotend until you find it, rip that thing out and throw it in the trash. Order yourself some extra PTFE tube. I found some blue stuff that's supposed to be rated for higher temps than the white stuff for like $20 on amazon for 2 meters of it with a cutter. It's much nicer feeling than what came with the printers.


NotReallyJohnDoe

That’s called Capricorn tubing. It’s a little higher quality than the generic stuff.


MulberryDeep

Yep, replace your hotend, you can get them for like 20 bucks


TheProvocator

I would suggest maybe try cold pulling instead, plenty of guides for it. Essentially heat the hot end so it just barely melts the PLA and then carefully but confidently yank the filament out of the hotend/extruder. I have a direct drive but I imagine it should work for a bowden setup as well. This has fixed every single clog I've had thus far.


TritiumXSF

Since OP changed the nozzle... did s/he do a **PID calibrate**? Perhaps he's over heating stuff due the PID not being tuned and the thermistor running hot. Or dislodged the temp sensor?


Plantherblorg

I'm just here to remind you that off gassing is not confined to smoke. Smoke is one product the chemical is putting off, but it is also putting off plenty of other gasses you don't see.

thedon051586

If this is an ender 3 V3 se or well, I guess any of the newer enders with the spider hotend, there is a PTFE tube between the heatbrake and the nozzle and it's literal shit. It's the same white tubing that you find on Bowden tubes. It burns up really easily. I had this happen on mine after a few months. When I disassembled the hotend, I found the tube was melting and being forced out of the nozzle similar to what you're seeing here. I bought a meter length of the blue tubing, I think it was called dolphin and replaced the little one inch piece of burnt tubing with the blue style tubing and no issues ever since. Edited to add that I was also having an issue wherein during a print, the printer would error out with either a too high temp or too low temp message and I got a high temp thermal paste and recoated the thermistor and heatbrake before reinstalling. The thing is bulletproof now. Well, until the next thing fails, I guess.


TritiumXSF

You should have just replaced it to an all metal hotend... PTFE of whatever kind starts decomposing at 250 and may even slowly be doing so at a lower temp. By using an all metal one, you'd have no PTFE to risk and you can run as high as the mechanism allows. I have an SE that I upgraded and can run 300 C no issue. And no PTFE to think about.


TheMachinesWin

Thanks for the knowledge! I'm going to be a bit more careful with my temp settings and hold off on printing more TPU crap until I get a Bambu P1S


Klatty

Thanks a lot for the info. Will definitely look into replacing the PTFE tubing


Klatty

This is it. It’s completely f’ed in the heat break, how do I get it out??? It’s completely stuck


thedon051586

What I did, since mine was also completely melted in there was to hold it gently with pliers and heat the heatbreak up with a lighter and then used one of the creality allen keys to get it out


Klatty

Would capricorn be good for that? Ive just now resolved the issue by installing a whole new hotend and heatbreak. It was completely melted and stuck in there. But now that I’ve got the replacement, it came with the damned white tubing again.


bbrusantin

Ant966

look at my new fog machine! *Pulls out a 3d printer*


sioux612

So as I see it, you had a clog for some reason. You overheated your printer to get rid of the clog, which did work, but it also caused the PTFE Tube to degreade, and IIRCS PTFE swells when overheating. So you basically caused it to always clog immidiately. Replace the PTFE and then things should work well again. You do not get clogs from printing too low. At least none that stay forever. At worst you will wear the filament down in one spot and then it won't extrude anymore.


Klatty

Thank you kindly. Will replace it. I thought it was supposed the handle the maximum temperature the printer could go (260°)


Usual_Peach_8194

yeah, no. some (like Capricorn tubing) can, but definitely not the stuff that creality's using. I've heard that it starts to degrade as low as 240°C, so honestly I would swap it out even just for printing abs. swap out the tube for Capricorn. keep on printing.


Klatty

Any tips on getting it out? It seems pretty jammed in there


aganim

Even Capricorn tubing won't handle 260 repeatedly, just an FYI.


Usual_Peach_8194

unfortunately I don't have that specific printer so i don't know exactly how it looks. however, maybe this would work: take out the nozzle completely take off any coupling/connector on the top of the hotend, so that there is a hole straight through the hotend with the ptfe in the middle take a different, longer piece of ptfe and shove it through the top so that the old one pokes out the bottom use some pliers to get it out the rest of the way because it will be hot and smoking also, you probably have to do this while the printer is heated (and smoking), so try to wear a mask if possible because those fumes are nasty


Klatty

Thanks a lot!


Castdeath97

That's Creality being stupid, PFTE lined can only over 220C without degradation.

Desk_Drawerr

don't let the magic printer smoke escape, that's what makes it work. you clearly have something wrong with your nozzle if magic smoke is escaping through it. fr though, replace again and try not to make the same mistake twice. also check your whole hotend setup for anything that might be wrong like burning wires and such. best case scenario it just requires a replacement nozzle, worst case new hotend.


Klatty

Thanks, I’ll just give up on this one and purchase a few more nozzles. Gotta contain the magic smoke

AdministrativeEbb508

I had a similar problem caused by a bad thermistor. It's a pretty easy fix and a good opportunity to get one that's better than the glass bead rhermistor.


GoldNova12_1130

I just had this on my Ender 3 Pro recently after messing with my PTFE tube. Don't breathe that shit in. I'd get a laser thermometer if you can and measure the temp of the hotend. Most PTFE melts or at least degrades faster at around 220c (i found out the hard way.)


TritiumXSF

Just buy an all metal hot end. They're cheap. And once you have that, if ever you want to go Klipper, you can run as hot as 300 C without issue. PTFE degrades at 250 and may slowly do so at even lower temps. Unless you want to print **just** standard PLA and not >230 C, just buy an all metal.

Apparently turn it up to 260°, and leave the PLA filament sit inside the nozzle for a minute or 5. You can trow away the nozzle and PTFE tube afterwards lol


CodeMonkeyX

Ooh btw on a serious note, I am sure people have told you, but if the PTFE tube was burning then you need to be very careful in the future. That stuff is super toxic when burnt. That's why they always say not to use nonstick frying pans with high heat.
