- Ender 3 v2 Hotend Cleaning - Eliminate Stringing & Clogs
In this video i'm going to show you how to clean out the hotend on your Ender 3 v2 or any other 3d printer that doesn't have an all metal hotend.
If you're having problems with stringing, clogs, or just keep seeing a previous colour coming through when you change filament, it's time to clean your hotend.

You say thanks for watching.. we say, thanks very much for taking time to produce this very concise video that helps us.
I've watched countless printer video's and never seen this loose nozzle trick. I love it thank you!
Real note... I actually try to like every video I see from you because of the quality of the content and practical wisdom. I almost forgot until you said it this time XD.
As clear, as informative and as helpful as I am starting to expect from such a quality channel. Excellent stuff.
Agreed. Great video. I like the extra step to back off the nozzle by a full turn and tighten after the Bowden tube is in place, for a tight seal.
Edit: I wrote the below before I fixed the actual blob problem. Even though the stock Teflon tube had visibly degraded after many prints at 255C, replacing it with new Capricorn tubing didn't help. It also doesn't make sense that plastic can ooze outside the nozzle. For this there is a second culprit: the joint between the brass nozzle and the steel heat break tube, inside the aluminum heat block. I removed the heat block and noticed that the bottom of the heat break tube's threaded portion (where it mates with the nozzle) was charred and somewhat degraded. This has to be clean and flat for a good seal. So I used a metal nail file to flatten and smooth this again. Minor leakage from the Bowden tube/nozzle seal should not get out past the heat break tube/nozzle seal. Evidently it was in my case and oozing past the nozzle threads in the heat block, onto the outside of the nozzle and down. Trying a test print now...
Previous text: One extra symptom of a burnt up Teflon Bowden tube to add though: I had been doing quite a few PETG prints at 255C nozzle temperature with the original Creality Teflon tube, so I had actually been expecting the tube to degrade where it meets the nozzle but the problem symptom was not what I expected. I was expecting clogs, and you mention stringing, but I was getting unexplained layer shifts and/or parts coming off the bed mid-print. This seemed to happen at random with some prints working fine. I finally figured out that this was caused by plastic oozing past on the OUTSIDE of the nozzle, where it builds up into a fairly big blob. The blob eventually comes off and adheres to the print. On the next layer, the hot end hits the hardened blob, and the impact is enough to knock the print off the bed even if bed adhesion is good. A mess of spaghetti ensues. Then I was printing some flat, thin mounting plates that cannot be knocked off the bed with sideways force because the surface area is just way too big, but I was getting layer shifts. In this case the hot end strikes the hardened blob hard enough to make stepper motors skip, resulting in misalignment. Surprisingly I didn't find evidence of these big blobs until the Teflon tube degradation got bad enough that plastic began leaking past the nozzle faster. Then I could see the plastic building up on the outside of the nozzle and coming off after enough had built up. Luckily I had Capricorn tubing ready to go and this video to gain insight from. Cheers!
Very informative instructions that I would have not anticipated. Excellent help for anyone with limited experience.
Awesome info! Thank you very much! I have been struggling with stringing for weeks. I re calibrated everything! I can't wait to give this a try. Just peeking through the little hole in the side of my hot end, I can see build up. I am sure this is the cause.
Thanks for making this! I'm a hobbyist that has reached the point of needing to unclog my hotend, this will be my guide!
Extremely helpful. I panicked when I saw my extruder head clogged with filament and this helped out tremendously! Back to printing.
Your videos have helped me substantially getting my printer going thank you.
you weren't just the best, but also the only one, who could explain it understandable and very helpful, step by step... you just saved me a sleepless night, a few hundred € and much stress... thank you very much
Glad to help Paul👍
I'm surprised I've never been suggested these videos before. I guess they are recent but all I see is TechTutor, CHEP and CNC Kitchen but your content is on their level, straight to the point and specific to the Ender 3 - great!
Had some issues with the extruder skipping with a new nozzle on. Turned out the hotend was clogged with filament even from the past owner! Thanks for the tutorial, works great now
Thank you. Like, genuinley thank you. I have an Ender 3 and an Ender 3 V2 and neither of them were working correctly, and I was considering just trashing both of them and buying a Prusa (which I still plan on doing but I wasn't going to print anything until I got it). No other tutorial helped me, but then your method of using the bowden tube to get rid of clogs has revitalized both of my printers. Not only this video, but also the trimming guide has saved both of my printers from the trash. Seriously, you're a lifesaver :D
Really glad some of my videos have helped get your machines up and running. Well done for not giving up👍
Not sure what I would do without you ha i've used this video twice now to help me out. Appreciate your work. Thank you!
I've had my 3D printer for like a year now, haven't thought once to clean it but now it's giving my a lot of stringing. Super helpful, Going to make the recommended purchases. Thank you so much!
Been having issues with my Ender 3 and I knew it was something to do with the nozzle or the tubing. I found your video to be really helpful in figuring out my issues and now everything is working just fine. Thank you so much :)
Awesome, thanks for letting me know 👍
I have been printing with PLA for about 2 years on my Ender 3 pro, had a few issues here and there with stringing and blobs but nothing major until I recently started using PETG so I have a sneaky suspicion the nozzle is at fault. Going to be buying the upgraded tubing and give my nozzle a thorough cleaning. Thanks for the great video 😃
Thank you VERY much Ricky!
I have an Ender 3 V2 Neo and despite the little differences, it was enough to do the whole process.
The only issue I had was that the cold filament broke inside the tube while pulling it out so I had to detach the tube from the stepper side too, and using any tool I was able to grab the little part of the filament that was still there and removed it (considering to keep the other side hot to be able to extract the nozzle side part of the tube/filament).
Thank you again!
Excellent video, clear and concise. This was exactly what I was looking for. Thank you!!
Thank you, man! Your advice helps me with extruder knocking. There was a clogging and a large piece of plastic in my hot end on Ender 3.
Thank you! I’m new to printing and saw a similar video for my Anycubic. I was in disbelief about sliding the tube back and forth (I figured it would be something more complex) You’re instructions confirmed this is the correct way to do it. Time to start cleaning.
Yep, nice and simple thankfully👍
Thank you so much for your help and tutorials. You've made printing make better sense to me as Ive only just started.
I’m so glad I came across this video, I had to change my Bowden tube as the original one was damaged but couldn’t figure out why it kept coming out of the pneumatic holder. Now I’ve ordered new nozzles and pneumatic tube so I can work on this on weekend
Thanks for the video. I started a printing project with my daughter over the Holidays just to wake up to a clogged hot end. Thanks for saving the day!
Man, you are really good at explaining things! Thank you so much
I think we may have a new world record for the amount of times the word 'nozzle' is used in one video. How many can you count?🤣
Thanks its a Longer LK1 3D and the aluminium tube inside one element the top part it's about 50mm in length, about 20mm of that tube narrows and Bowden diameter too wide for it. So fixing Bowden into extruder top piece it only goes in approx 30mm. You cant push it all the way through as in your video. Though ive taken apart and cleaned each piece of extruder section, filament still comes out stringy. I'll need to troubleshoot it more... Not sure what's going on yet.
Thank you for these instructions, they worked great. I just experienced my first blockage and didn't know what to do. The only thing I would like to add is that I also had a blockage within the white tube which I couldn't clear at first. I ended up heating the tube where the blockage was using a heat gun and then used some filament to push out the blockage. That worked great.. Thanks again.
Thank you sooooo much. I have had my Anycubic Vyper 10 months and thought it was broken, this helped me fix the problem and I am now up and running brilliantly!
Followed instructions, totally worked. I thought my bed needed cleaning but this fixed my whisping problem!
Thank you for the video. I did not think to check the center of the hot end a clog, which was my issue. Went threw 3 nozzles and 1 new Bowden tube section... Thought it was suppose to be a stop in the center so when you said to push all way down through the hot end . . . That was my issue for last 4 hours of trouble shooting. Thank you!
This worked for me. I thought unclogging my nozzle was going to be a laborious pain. Thanks to this video it was neither. Grazie !
Once Again, You Have The BEST 3D Printer Videos. Thank You.
Excellent video, I was getting blobbing on my hot end. After watching your video I found out that it was being caused by a loose nozzle. I cleaned out the hot end, replaced the nozzle and tightened it up as per your instructions. Now my prints are working perfectly. Thank you for sharing your expertise!
Not one of your videos have failed me yet. Subbed. 😆
Thank you so so so much for this tutorial. I was so scared to start poking my Ender 3 and was fairly convinced the nozzle was clogged.. as it was. You saved me a million tears of frustration and probably burning my fingers too :D
Great, really glad it helped 👍
Brilliant content. It may seem obvious for a lot of people, but to go through it so clearly means I now have a system and knowledge of how to do it. It worked great! thank you.
Glad it was helpful, thanks for the comment. I try very hard to not patronize as I remember how it was when I didn't know any of this stuff yet.
@@RickyImpey it's pitched very well and not patronising in the slightest. If people do find it... They are maybe watching the wrong video. For me as a newbie, it's not, it just taught me how to do it, but also done in a systematic way so I will remember it in the future.
Nice one.
Thanks for the very clear and very descriptive instructions.
I cannot even explain how many complicated things i've tried.. and how many parts i've changed.. turns out *LMAO* there was a big ol' PLA in form of a tube stuck above the nozzle, sealing the passage for new pla (HENCE the clicking sound from extruder wheels. feeder.) This video help me realize you can put whole feeding tube through the part where nozzle sits...that's why I've pulled out this chunk of PLA out...Wish I could post a pic here lmao. I'll put it on my shelf with figurines i've made as an achievement, reminder. lmao
Same lmfao
Suuuuper helpful video, explained everything A-Z and really helped me out, learned so much
Your becoming my favorite source of help even when it doesn't match my machine.
I wanted to do a clean just to try. Did a cold pull that broke the filament, ended up with a chunk of filament that couldn't be reached by heat and couldn't be pushed.
I have an Elegoo Neptune 3 and you can't push the bowden tube all the way through, but thanks to this video I removed the pneumatic fitting which helped me reach the blockage.
Great to hear, thanks for taking the time to leave a comment👍
This worked perfectly, i suspected my tube being bad, so i got the one you had suggested funny enough, and then replaced the hot end, but it was beading now(before it wasnt printing at all) but your trick fixed it right up
Thank you so much!!! I had a clog half a centimeter big after my filament tangled and broke the tube out.. Awesome Video!!
The Creality tutorial is easy to follow but your video adds more extra details and tips without pushing the duration too much. Thanks!
My Ender 3 v2 had been clicking for some days and finally able to rid the clog from the PTFE tube thanks to your video! Hopefully that was the culprit and nothing else otherwise I'm lost because I have tried most other troubleshoots
Really hope this has fixed your issue for you👍
@@RickyImpey I appreciate it! I've seen some of your videos and they are helpful and concise. Subbing to your channel 👍
Thanks for this video... Removed clogged filament in my hotend from the ender 3d v2 neo max, just as you described. Amazing how i could follow and replicate your actions! keep up with the good work!
You are awesome man!
Thanks mate.
Just helped me do my first nozzle change and hot end clean.
Your vids so help me, your my goto since I followed your Ender 3 v2 build (got a great first print a month ago after following the vid)
Keep them coming, I’ll need them lol 😎👍🏻
Good stuff, thanks for the comment, I need the motivation sometimes 👍
@@RickyImpey you deserve it mate.
Your vids are to the point, informative and no waffle.
I have the sunlu S1, and even thinking about the fan mod 🥴
I’ve only been printing for a month 😬👍🏻
Thank you so much for saving my sanity. I was printing a benchy for some nostalgia and at the 6th layer, my hot end suddenly clogged. I recently had under extrusion issues, but I didn't think that this was the problem although it happened to me before.
Best video I've seen on how to do this. Thank You!
Glad it helped!
This video was a lifesaver for me/my 3D Printer!
Thanks so much for this. I was having issues where filament wasn't coming out of my Ender 3 nozzle, I changed the nozzle head and still saw no change, little did I know my hot end was clogged. I followed the steps you explained and out popped a large plastic clog. All is fine now, printing like brand new. 👍🏽👍🏽👍🏽👍🏽👍🏽😊
Awesome, glad it helped
So informative Thank you!! Cleaned my ender 3 pro. Best video
Very well done clear and precise video. Thank you!
This is awesome thanks. Had a leak and thought I needed a whole new assembly
Old video, but still relevant and helpful! Thanks, got my Ender 3 v2 running clean again. Will consider an upgrade, but so glad to keep this running!
Glad it helped!
Great video and really detailed explanation, I have been struggling with a clogging nozzle for a few weeks now and was trying to figure out if i did something wrong when cleaning the nozzle.
Turns out that i shouldn't fully tighten the nozzle until the bowden tube is in place..
Simply thank you.
Glad it helped, yes unfortunately there are a number of small details that can really cause problems if overlooked.
The on video that actually helped me solve my issue, many thanks!
Very helpful, thank you. Followed the step and my printer is up and running again.
A very complete guide. Thank you
Hooraaayyy I’m printing again!! Thanks so much! I am new at this stuff and your video was clear and helpful.. I will be watching more!
Glad you found the video helpful 👍
Thank you for this video, exactly what I needed and described very well!
Glad it helped 👍
THANKS! You helped me unclog my printer, I've been having problems for some time now!
Glad the video helped, thanks for the comment 👍
Worked for me! Thanks! When I cleaned the nozzle and tube it looked like the filament had burnt a bit. It's white PLA, I had it at 200° and the stuff I cleaned out was brown.
another great video, straight to the point, thanks a lot
Thanks, clearly explained, very helpful!
Good, no nonsense information. Thank you.
Really appreciate your video, I solved my recent printing problems. Thanks a lot.
Your videos have helped me so much thank you and enjoy the coffee
Thanks very much👍
Great video, very clear and informative
Very helpful thanks. I cleaned mine today and did everything wrong! Will do it again the right way tomorrow.
Thank you. it is a great explementary video for cleaning the creality Ender extruder. helped me a lot :)
This is very clear. I just sorted out my problem by following the video step by step. Thanks!
Glad it helped Robert, thanks for the comment 👍
Thank you! Helped me loads!
thank you for a short but sufficent video
I got lucky. My pla string simply broke at the feeder. I carefully cut the sting flush on both ends and manully pushed the hot end and printing again. Thank you for the helpful information.
Thanks for this! Noticed print quality from my Overture Transparent Red PETG has been getting worse over time, seems to be flow related. Appreciate your clear detailed cleaning process. Cheers!
Thanks a lot man! i have ender 3v2 neo 3d and i just needed to get out a stuck fillament and found a solution in this video :D
Thank you so much! I thought my hot end was dead! your guide worked like a charm!
Great to hear👍
Thanks been struggling with this all weekend.
Hope it helped 👍
Thank you so much this video helped me immensely
Very good video, high quality of video and sound.
Thanks, I try👍
your voice is very reassuring, makes me less scared of taking apart my printer haha
Around the time I first got my printer on maybe my 3rd print my stock extruder failed and caused the most brutal clog in existence.. ever since that day and many upgrades later I’ll get a random blackish/purple glob of goop from the same purple silk filament from the clog that will drip onto my print and ruin it.. it’s extremely frustrating when you’re 6+ hours into a print and have to restart.. thanks for this video! Need to get mine all taken apart and cleaned!
I love how you included a link to the Ender 3 V2 printer, just in case that's the part that needs replacing 🤣
🤣
My Bowden tube is so trash I couldn't get it to go so freely through the hotend as you, almost as if it somehow became oversized all of a sudden, since it was the one that came with my Ender 3V2 Neo. Ever since I saw the hotend on my machine and compared to the V2 (non Neo) and others, I thought it was kinda trash anyway, so I'm changing the entire hotend anyway, but following this video to the T as it is the most concise I found. I was able to clean the entire thing no problem and disassemble it down to parts I didn't even know it had. Sadly, sometimes bad quality only leaves replacement as an option for repair.
Great Videos, best iv found thanks
this guide was amazing thank you. I actually used a method from another video to ensure tightness though, and that was to tighten the nozzle, then fit the capricorn tube through the new fitting at the top, press it in tightly against the nozzle and fit the clip, then tighten the slightly loose fitting at the top to compress against the nozzle.
Any particular reason or downside to this method versus yours?
for me it was easier as I did not have a good way to work with the hot nozzle without burning my self, so it was easier to ensure a good fit, but interested in your thoughts.
Super useful. Thank you very much.
thanks for the video. My ender 3 was clogged and that helped me :)
Thank you! This worked for me!
Thanks alot it was such a pain to fix, but I got it working
Thanks this really helped.
Excellent tutorial! I’m afraid the part where it says you only have 30s until the nozzle cools down .. I’m not sure I’ll be able to do all those steps you did within that 30 s period for my first time cleaning it out .. what issue can that cause if the nozzle cools down ?
First off thanks for this video!
It at least gave me the motivation to try and save my Ender 3 v2 Neo again, unfortunately in vain.
I managed to get the completely clogged nozzle off and clean in.
I have the original white PTFE tubing, however with nozzle completely off as stated I then cannot push the PTFE tubing all the way through to the other side like you did, even at 250°C, it just enters I'd say 1.5 to 2cm max from top.
However I managed to get a huge clogg out of the extruder using a thin steal screwdriver and could see completely through with a flashlight.
My hopes were on top, reassembled everything and the symptoms persisted, can't get it to extrude anymore and it cloggs again right after this.
This is my 2nd Ender 3 that worked perfectly well for 30 to 40 prints, then all of a sudden just needs to have a filament break or run out (which happens or will eventually happen), once it prints without filament for a while, you can forget that thing forever and it can never be revived.
I have 4 other older printers like A8 and prusa copies, etc. they still work, the quality is not as good as Ender3 but they still work.
I am sad and disappointed, and wish I was wrong about something and there'd be something I can do, but I don't want to put any more cash into this money pit-
Thank you!
This helped me thanks
Hi, Great video very helpful thanks. My printer might be different. I use standard 4mm Bowden tube with standard 1.75mm filament. Removing Bowden and nozzle I can get a 50mm Alan key from below to push up from below to come out barely at where Bowden would enter from above. I've cleaned and heated and believe the pathway now clean but my Bowden tube only appears to penetrate 20mm into heating fixture from above. I've another piece of narrow tubing for extruder section but it goes only 35mm into fixture. Machine must be designed to have the pathway narrow until it reaches 2mm width at a certain point. Here's hoping 20mm into heater fixture is enough for my Bowden tube to fit into the heating element. Thanks.
It sounds like, from what you are describing, that you have an all metal hotend. What printer do you have?
Rick, please do a tute on how to upgrade the firmware to Marlin or any firmware with better feature. Your channel is the first one i go to whenever i hit a dead-end on 3D printing. Thank You Rick!
Good to hear Bobby, I'll move firmware upgrades up the list for you👍
@@RickyImpey Cheers! I am still contemplating between Jyers and Klippers. Appreciate the great help! Stay safe Rick!
I use Esun cleaning filament, and it works wonders.
thank you.
great video
