Before you comment it, I know it's called an Allen Wrench. Anyways, be sure to subscribe for more!
Ha thanks for the video. It reminded me of a book called "Thing Explainer". The premise is to explain complex things using simple words (1000 most common words in English). Check it out.
I think the fact that you have the knowledge of a 3d printer, but couldn’t think of the word Allen wrench made the video 30x better. Great video though! Thank you for the information!
I was going to subscribe as I thought anyone who can do a repair vid on youtube on one of the world's biggest selling 3D printers and doesn't know the name of the Allen key (or L key? haven't heard that for a while) has some stones. I'll sub anyway.
Fun fact: its called dysnomia when you know a word, but you can’t remember it to say it but can give every detail about it. I learned this from the speech teacher at the school where i work. It is a very common dysfunction,
Do you have e a video on how to attach the wires once I buy from the link in the description?
I absolutely love how you basically didn't call anything by its actual name but still provided a very useful high quality tutorial XD
This was extremely helpful. I was learning about heat creep and replacing a bunch of parts when I realized my temps were fluctuating all over the place and triggering the thermal runaway. Solved my issue with less stress than anticipated. Thumbs way up.
Okay, so here's the deal. I'm 56 years old, and foolishly esteem myself to be a fairly smart person. I have two different jobs/careers, and both of them are doing things that most people would think would make me feel very confident and not really prone to worrying about failing at anything. But yet, I really, really was paranoid about breaking my 3D printer. It seems like such a magical device, that I don't want to ruin the magicalness of how it works. But it stopped working and had a serious problem. Your video was really, really great at helping me not be afraid to just rip into my printer and find the problem and fix it! So thank you for that!!! If you had been a narcissist, and not a real, just plain honest person, I would still be freaked out about doing this!
3 years later and your still very helpful. My heat block started oozing out filament and I couldn’t find any solution as I tried many different ways to stop the oozing. So I just decided to buy a brand new hot end. This video helped me and we’re working perfectly again.
Other 3D Printer TH-camrs: it’s super easy to do! Unscrew the barrakiltzenfrug with the panda mania screw and take the whole thing over to your fully equipped and dedicated soldering workspace and fuse everything together, then measure voltage and current with these 12 specific gadgets that you definitely have just lying around, and then just completely rewire the whole board for fun because it’s so *obviously* not done efficiently.
Callum: use the funky wrenches to loosen these screws…I can never choose the right one by sight…and put this hot cylinder thing and this bulb thing back here…
Much more relatable, easy to understand, and overall on my skill level! 3D printing is now affordable for the average person, and it shouldn’t feel like a tech-nerd elitist club to navigate the problems. Thanks!
3 yrs ago and man I appreciate it. The little details really help calm the mind if I think I'm messing up
Honestly this is exactly what i was looking for. You the man. Thank you so much for making this
This same exact happened to me too. I have no idea when it got stopped but when I went to screw the nozzle back in it was just stripped. Thanks for the video it was super helpful!
Subbed and liked man. Video is a lifesaver. Thanks a ton.
Glad we could help!
Good job - appreciated the straightforward guide!
I see the other points have been mentioned, but just to recap:
Allen wrench - sometimes called a hex key, named for Allen Manufacturing
Heating Element - The silver tube that goes into the big hole and held in place by the grub screw, it's what heats the hot end
Thermistor - This is the small bit that went into the small hole that was held in place by the larger screw, and is what reads the temperature of the hot end
Thermal Paste - Ditch this, it's actually impairing airflow across your heat sink fins
Dont worry, I ditched the thermal paste a long time ago, idk what I was thinking. And what's ironic about this comment is that my thermistor just broke lol
thank you thank you thank you. very clearly explained - and my ender is now up, running and happy.
I had the same exact issue as you. This video helped a lot, thanks.
Thank you for leaving the old unit out so I could verify where ti put thermal paste 👍👍
Just found this and you saved me a ton of aggravation and blind guesswork. 💯 I used your affiliate link! 💯thank you!
whatever you are calling anything ;-) you helped me a lot. There were new cables on my new hotend and I was unsure if I just should keep the old cables, and 'cos of your video I did
Thank you for making this video. It was very helpful.
Very nice video! I cracked my nozzle off and ruined the hot end by getting it stuck, and this was a great tutorial for replacing it. I have a Voxelab Aquila printer, but under the fan shroud it is identical to this one. I was able to replace my hot end very easily thanks to this.
Great video, just what I needed. Thanks!
No problem!
Hey man! You’re awesome! I’m definitely hitting subscribe and hope you get 1000!! 🤘🏼🤘🏼🤘🏼
I have 2.3k but thanks anyway😅
@@CallumPrints well deserved! You’ll take my job one day! 😉🚀
Heck of a video man thanks for the help
Hey thanks man, this really helped!
Thank you so much, I couldn't find a tutorial on how to change the heat block but this was close enough. Really saved me!
PS: I also stripped the heat block and the nozzle wouldn't go back it properly.
Absolute lifesaver
ı watched many video but that was great and most helpful one
sweet video definitely sending a sub
Thank for the info buddy!
Sir I thank you for this video. It helped me greatly. The tools you were referring to are called Allen wrench, or more correctly hex keys.
Actually, the correct original name is 'allen key' . Hex key came much later. And no need for a capital 'A'.
I fixed this, then broke it again. Thank you!
They're called allen wrenches. And your silver cylinder is your heater cartridge.
Probably should've known that the wrench was called an Allen wrench, that's my bad. Thanks for letting me know!
Thanks my guy.
At 8 minutes, that screw is meant to gently press the 2 little legs of wire insulation (the opaque stuff) into the side of the hot end. The way you've done it the screw is doing absolutely nothing. So the temp sensor (which is what that wire does) is free to pop out of the hot end at any time... I came to the video to get an understanding of what goes where and i've gained that before tearing my own printer apart so thanks for that. But this video is open to leading those less competent astray.
Heeey, thermal paste helps parts conduct heat between them. A good place for thermal paste, would be between the heat block and the thermistor close to the nozzle. Conducting more heat to the thermistor, sealing any gaps between the two, helping the printer more accurately know what the hot end temp is.
A bad place for thermal paste, would be using it to clog up the cooling fins, impeding air flow over them, reducing cooling area, increasing temps of what your trying to cool, etc... noticing on the old hot end 🙃.
Thank you so much bro
you can just replace the heating block of course, but may as well replace the lot, isn't much to buy a heat sink (the finned thing)
Thanks and greetings from Sao Paulo, Brazil.
Greetings! Glad this helped
Thanks!
In the UK we call them Allen keys, they are also know has hex keys/ wrenches.
The silver thing that goes inside the hot end is the Thermistor and the screw in thingy that you where using was a ball end allen wrench, also the fan box thing is called the fan shroud. Good video though.
The silver cylinder is the heater cartridge. The thermistor is the bulb-looking senser next to it.
helpful video. Though my problem is the hot end is not heating up, so I think I have to change my thermister itself and the wires attached to it
Yeah, check your thermistor and your heating cylinder. It's likely one of those two is broken. In fact, I just had to change one of mine recently
Thanks. I put a new end in and forgot to relevel the bed. The end crashed into the bed and bent the heating tube. Lesson learned.
i have bought hotend without a PTFE pipe. Should i mount that on hot temperature like 240? Both (hotend, and ptfe) are totally new without filament.
Thanks you!
No problem!
I know this is from a year ago, but the tool is called Allen Wrench. Also, you went off topic a few times by talking about how to remove filament, changing the Bowden tube; etc. Overall it explained enough
Fan shroud. No idea what the allen wrench with the weird round hex driver thing on one end is actually called. You are welcome. Great vid. Thanks!
FYI, thermalpaste isn't going to give a better heat reduction in this case. Actually the opposite because it closes the gaps that are made for the hot air to dissappear..
When thermalpaste is applied you have to have a cooler touching the paste psychically, like a Cpu cooler touches the thermalpaste that's applied to the Cpu, to transport the heat away..
Otherwise good video.. 🙂👍
Funny you mention this, because I have removed that thermal paste since for the reasons stated above. I made a video about stopping heat creep that mentioned the thermal paste, and I took that one down (kinda) after finding this out.
@@CallumPrints oh, okay 👌 my bad, didn't check your channel😅😊 sorry for that.
Have a good day😎
Hex key, Allen wrench, L wrench, the start ones are called torx
Me too! Stripped it.
The screwy thingy is called an Allen Wrench
The "black box" is called the shroud 👍
Thank you
You are welcome!
i was unscrewing the top metal brass part where the bowden tube is coming through, but i cant screw it back into the hot end
Does this work for ender 3 s1 also?
Thanks for the video. Those tools are hex keys.
Why you are using thermal paste in unknown to me. Thermal paste is used to make 2 metal surfaces transfer heat better by making a flat surface contact with another flat surface to fill in any high or low spots that other words would not be touching the other piece due to pits in the flat surface. Even though something may appear flat and smooth everything always has dips and pits making a less than perfect contacting area. I guess to each their own, although it's probably pretty messy to deal with. Thermal paste on computers is used for the lid of the processor to contact the heat sink that is usually connected to a fan cooling the processor, not a heat sink to a fan. It probably might end up messing up your fan because it can get running when it's hot especially conductive thermal paste, and then it's just like water, moving in the direction of gravity. Allen wrench is the twisty device's name.
I'm curious how thermal paste "prevents" heat creep...
Isn't thermal paste used to facilitate heat transfer from a hot surface to a heat sink? This is what keeps CPUs from over heating... Hot CPU --> Thermal Paste --> Heat Sink --> heat dispersion... or am I wrong?
Trust me, that was a bad mistake. I dont have that paste there anymore.
@@CallumPrints ever since I first watched this video like 3-4 months ago I was thinking to comment about this thermal paste issue and both say it might be a bad idea and ask the reasoning behind it, and now I read your comment which makes me relieved, thank you!
A tip for you is to write out a script and then you will realize that you don't know the name of the parts you are messing with. Then you can google the parts learn the name and sound professional, instead of saying that thing and this thingy-ma-bob haha. Hey if you go online you can type in Ender 3 upgrade prints and you can print out some upgrades for your printer. My favorite is a motherboard fan protector, which protects the fan and motherboard from getting any filament in it while you're printing or cleaning your printer.
Around 5:40 he is able to take the metal heat thing but I'm not able to. I took out the screws fully and I'm having a hard time getting it out. Does anyone have any advice?
The part that I wanted to see you didn´t show it. The blue tube, how long does you insert it?
Screw in your nozzle all the way, unscrew by a quarter turn. Push your bowden tube all the way flush, tighten nozzle the rest of the way.
Yeah i undid the grub screw and the "metal heat cylinder" wont come out....
man mine did the exact same thing
It’s called a Allen wrench
The unscrew device is called an Axel
Hex key or Allen wrench.
What were the symptoms of your stripped hot end? I'm having balls of plastic come from above the nozzle on my printer and I think I stripped it or there's some plastic in the threads
If you've replaced your nozzle recently, you may have just not put the tube back into the hot end correctly. This happened to me a while back, and you're supposed to put your old nozzle and the tube back in in a specific way. Here's a link that could help you out: th-cam.com/video/FRzsGttNMyk/w-d-xo.html&ab_channel=Tombof3DPrintedHorrors
@@CallumPrints there's no link, I guess youtube filtered it or something
I didnt have the link yet, I edited my comment on my PC but initially responded on my phone. There should be a link there now! Hopefully it helps
@@CallumPrints Thank you, that seems to have fixed my issue
Awesome man! Glad I could help!
umm why would you put thermal paste on the heat sink?! ur not trying to move heat from heatsing to any other metal part since its "floating"
i didnt even know that silicone thing was meant to be on it i though it was packaging protection ro something bru?? atleast i still have it somewhere i might goahead and put it on i guess also i came here to figure out how to deep clean the filament out of the head
the wrench you are trying to find the name for is an Allen Wrench.
its a heater cartridge
My case was I was an idiot and forgot to heat up my hot-end and retract filament before trying to change out the nozzle. Maybe this nozzle had a weak point but suffice it to say The nozzle sheared clean off and I had half the nozzle stuck in the hot end. Using a screw extractor didn't work either. =P
I was doing the same thing but my nozzle snapped while screwing it back in! Glad to see my faux pas wasn't the first.
Thank you buff cole sprouse.
It’s an Alan wrench by the way
Had a similar thing happen with my stock hotend (ender 3 pro). I don't remember messing with the set screw for the heat cartridge, but I went to change the cartridge, and the screw was stripped. I assume from the factory, kinda odd.
1:20 My exact problem.
Its an alen wrench
its an allen wrench btw
Alan wrench
You stripped the heat block not the hot end. Believe me if you just get a new heat block it can be much cheaper. But I can’t tell u what to do lol
Allen wrench
Allen keys my friend
Many steps to take pieces like the thermistor off that’s unnecessary and also can be a pain to new to 3d printer users
Allen Wrench
Allen Wrenches
My grub screw is stuck😭
Broke it*
Allen wrench is what it is, you are welcome
...... Did you seriously just rub thermal paste all over your heatsink? That's not how thermal paste works. It's not a magic cooling paste. Thermal paste acts as a sealant of microscopic airgaps on heatsource, to heatsink connections. A small layer goes around the metal cylinder that connects to the heatsink, and makes the heat transfer to the sink much more effectively. An absolute minimum should ever be used as metal is always better than paste. By smearing it all over your heatsink, you just significantly reduced the actual metal surface area, thus reducing its ability to be cooled. The reason it has fins to begin with is to increase its metal surface area.
5:38 I've loosened and in fact completely removed the tiny screw, but the "heat cylinder" is not coming out of the...metal brick. does anybody have any suggestions?
if your still stuck use an allen wrench to push it through from the other side its prob got some melted plastic on it
I did that then my 3d printer pulled an error THERMAL RUNAWAY: E1 PRINTER HALTED
You likely forgot to put that little glass bead (the thermistor) in the right place. It's also possible that you have a faulty thermistor, and that would require getting a new one
@@CallumPrints yup and it took me 3 hours to figure out how to install the new therimistor that came with the hot end 🤣🤣🤣🤣 thanks a lot for replying
i didnt know justin bieber did 3d printing
LOL Allen key...
You're using the wrong size screw driver, that's why you had difficulty undoing it. Right size, right profile will make a huge difference! (The "heat cylinder" is called a thermistor. Instead of apologizing for not knowing terms, learn the terms first: contributes greatly to credibility! The video itself is great.)
ok so you are great at video making but your technical knowledge is lacking (you do not know the correct name for the tools you are using ,or the parts you are adjusting ) so please get yourself some tech speak knowledge ,make another video and this time rem the tech speak so at lease you will sound like a pro and leave the street talk behind and you will see an amazing number of likes and suscribes.
dude you need to learn terminology. How do you expect people to want to learn from you if you're constantly fumbling over your words?
Seems to have helped a lot of people so far. That's why I have a visual aid to make up for my stupidity
This wasn't fucking helpful at all, this is just to remove the heatsink and heat break, the hotend is all wired and requires a full change
So in other words, this tutorial is helpful for some people but you see looking for "something different" and the tutorial is, in conclusion, "fucking useless." Yeah, this isnt a full wire replacement, just the head. But don't call the whole thing useless just because it wasnt of use to you.
@@CallumPrints when the title "How to Replace the Hot End" this means actually changing the whole part, otherwise it should be called "How to Replace the Heatsink" as it's a more accurate title. So if someone's heat sink has actually burned out, like mine did, so yes this is completely fucking useless because it doesn't address the promised issue.
umm why would you put thermal paste on the heat sink?! ur not trying to move heat from heatsing to any other metal part since its "floating"
Just so you know, I dont have thermal paste on my nozzle anymore, I thought this would be a good idea but instead it does absolutely nothing. This video was from a while ago😅
@@CallumPrints no, it is a good idea. Most people do it. Correctly. Thermal paste goes on the metal tube that goes inside the heatsink. You just out on thermal paste without learning what it actually does. It does a fantastic job of creating an airtight bond with the sink, hence why it is sold at every 3d printer store, and all metal hotends should never be used without it
