Once again you have been my hero. I was having problems with prints not completing, the extruder motor was skipping and I thought it was due to heat fluctuation and the nozzle clogging up. I tried tuning the heat temperature, but that only slightly helped. I then came across this fix and thought, why not. I did this and so far my problems have gone away, smooth printing and completes to the end. Thank you so much.

[@hcpookie]

If you already have calipers, you can use the depth gauge end to measure the interior directly. No need to use any filament

[@haydenfrost9388]

brilliant!!! after months of printing, 3 of my ender 3s all started having issues and i couldn't get any consistent prints and 1000 failed prints. i have just tested this on one machine and i am now getting some of the best print quality! cant thank you enough for this guide! excited to fix the rest of my enders

[@SneakyBastdAU]

Was getting extruder clicking and slipping, and came across this video. Tried it out and it's printing sweetly again. Thanks!

[@ilaser4064]

Just thought I'd add that you really want to ensure there's no filament left in the hot end prior to doing this. The best way to do that is to remove the nozzle and push the PTFE tube the whole way through the hot end. I found that out the hard way, as I was still getting stringing. :)

[@felipeandias3926]

Hey Chuck, I just wanted to say thank you so much. I'm from Santiago, Chile. I started a new 3D cookie cutters business and at the beginning I was so frustrated with all the "common" printing Issues. Now I have to say, if it wasn't for you, it would've been impossible for me to have this business and run my CR-10 farm successfully. You know in my country, 3D printing is relatively new and there is no one to turn to if you need help. That's why I can't thank you enough sir. Cheers!

[@bhein67]

Hi Chuck. I just received my first printer (Ender 3) a few weeks ago (just before all this quarantine/lock down business thankfully) and just found your channel. I really appreciate your approach, presentation and explanations. Thanks for all your advice for those of us that are new to this great hobby. Cheers from Canada p.s. just sub'd

[@maximobassignana9452]

Chuck, YOU ARE A FREAKING MACHINE when it comes to 3D printing. Really, just as insightful as a college class would be or maybe even more, please keep it up as i still have a lot more to learn from you

[@PilotPlater]

I appreciate this. I've been having many hot end issues lately on my ender 5, my printer has just been offline for over a month because I don't have time to fight with it. This gives some good ideas to get it back going.

[@LordHonkInc]

After nearly a year running this mod, I've got to come back here to say this is an absolute lifesaver to avoid that little bit of slop that just tends to develop over time as the teeth in the coupler eat away at the PTFE tube. I've been printing almost exclusively PLA, so even after all this time and a couple kilos of filament, the part stuck in the hotend hasn't failed (yet, though I'm checking it regularly) and I've had literally zero issues with clogging or stringing getting worse over time, as it had before. Also, disconnecting the bowden without potentially messing up the tubenozzle alignment is just such a welcome bonus. Literally a must-have, coffee-break length modification.

[@rodbacon9489]

I had problems with my new Ender 6. The pressure on the bowden tube coupler at the hot end would cause the tube to badly groove inside the connector after only a minimal number of prints, causing blockages. The tube would also gradually creep back from the hot end, yet another cause of blockage and frustration. I'd wasted multiple lengths of bowden tube before finding this video. I was able to salvage some of my capricorn tube, measure cut and fit (after printing the washer) and then replace the main length of bowden tube with a slightly cheaper alternative that I can source locally. I printed the washer at .12mm resolution using PETG (because it's what I had loaded) and it came out brilliantly. Six prints into my new setup, and no hint of problems yet. Fingers crossed!

[@Inspironator]

Thank you. I appreciate your hard work on this issue. I've been struggling with this problem for 18 months and I've finally ended up at tubing insertion depth. Now you've given me confidence to dust off my cr10 and put it to work.

[@Zachary3DPrints]

When I did Luke Hatfields hot-end fix, I used a metal washer that fitted right into the coupler part and the filament could go right through

[@wink1275]

Thank you so much. My son sent me the video after me whining to him about my printer. He printed me a washer, I followed video and my first print was almost flawless.

[@thatgreenone]

What material did you use for the washer?

[@SianaGearz]

"PTFE cannot lose its lubrication" but after being exposed to enough heat, the compound in the throat is no longer going to be PTFE, but its pyrolisis products.

[@christopherwhitcomb6233]

Thanks so much. This mod worked on first try. I tried the Luke version with somewhat iffy results but the tapered spacer fit better and filament glides right through. It’s guys like you that help the hobbyists slowly become pros and keeps us from giving up. You rock and made my day with this video. Now to do 7 more creality machines. I don’t sell prints but I sure do a mess load for myself and my family till I get real good.

[@xblackdemonx]

Best fix EVER! Before this i had non-stop clogs

[@smorris12]

These videos are an oasis of calm in a world of overproduced noise! Today's project tho I'll probably make the washer in ally so my lathe doesn't sulk!

[@reasonablebeing5392]

Great mod by Luke made better with Chuck's improvements. But I have found that even the Capricorn PTFE degrades over time especially if you print at hotter temperatures for PETG or print a lot of long duration prints. Best advice is to inspect your Capricorn PTFE at regular intervals or any time you are changing nozzles where you are disassembling the hot end.

[@amaugeri]

After 3 years 3d printing on an Anet A8 I finally got an Ender 3 Pro and boy what a step up. I'm getting prints that were not happening with the Anet. The first 2 weeks the ender 3 Pro was printing perfectly and I was totally happy. But suddenly the prints were bad. I discovered you video on estep calibration and now I'm back with perfect prints again. Thanks Chuck.

[@dnbadamwalker]

I recommend this mod as a backup too i had the tube snap and needed some parts to provent a line stop this got us back up and running

[@rchokelal]

I actually cleared a major jam in my hotend and cut about 8 mm off the bottom of my tubing. I re-seated the tubing and all is well. BUT I was worried I would need to do it again. This seems like a brilliant solution. I will print the washer in ABS to resist the heat of standard PLA prints and other materials. Great solution and technique to figure out insert length.

[@chrismckay3868]

when assembling this hotend setup use a spare piece of filament down in the nozzle to make sure the washer and capricorn tubing line up accurately. also to prevent the ptfe tube from walking out of the lock fittings use a small dab of shoe goe between the ptfe tube and the plastic retaining ring and wait for it to set. I had ptfe tubing wear and start moving in and out of the pneumatic fittings due to the constant rotating cutting a groove in the tubing, once I applied the easily removable glue to the tube and the lock collar i have never had it come lose without me wanting it to again.

[@johnhilman9922]

Applied this fix to my AnyCubic Mega S printer and it does absolutely work great. I'm amazed at how clean the prints are after making this change.

[@TheWoodWorkingPilot]

I love your videos and they are very helpful and informative, but one thing I just can't figure how and it's why you glorify the Capricorn tube cutter so much? it sucks - the blade flexes while cutting and the cut is angled 100% of the times, let alone that it doesn't hold the tube straight, and the tube is always curved... What am I missing here?

[@keithadams240]

Chuck you are awesome. Such simple easy fixes making the biggest difference. Who would have thought?

[@stevebailey1682]

Hey Chuck...do you still use this technique on all your Creality printers? This video was more than a year ago, so thought your opinion may have changed.

[@FilamentFriday]

Thank You.

[@kaotictube]

While this is a nice fix, the washer is redundant. Just cut the tube inside the hotend a little short, insert,then install the coupler, screw until it's about 1 and a half turn out from end, insert the long tube at the top until it makes contact with the cut tube inside, lock the coupler, and screw it tight. That last 1.5 turns is enough to push the tube down and keep it in place. Been running it this way on my ender 3 v2 for over 2 months and no issues.

[@Sokol9r]

This helped me so goddamn much I owe my printers existence to you

[@kaotictube]

@@Sokol9r Glad I can help! Happy printing!

[@kaotictube]

@@Sokol9r ps the same trick works on the extruder end. Just no inner tube to worry about.

[@FilamentFriday]

Kaotictube - That still relies on the coupler holding the PTFE in place. Might as well just not cut the PTFE and use one piece like stock setup.

[@kaotictube]

@@FilamentFriday that is true but it prevents cutting a whole bowden tube as you only need to cut a length for the inner tube and retain the main section, as is the purpose of your video which I appreciate.

[@KevinDC5]

I can truly attest to the value of this simple fix. Im here to watch the video again, because i had a fan go out and deciding to rebuild the hotend while im in there, and since because it has been over a year

[@JSeds]

I believe the PTFE should be cut .5-1mm longer than the calculated distance so that the nozzle presses firmly against the PTFE tube and leaves no gap. One way to do this and avoid any measuring, is to remove the heatsink with the heatbreak from the heatblock and insert a long tube with the washer and bowden coupler in place. Cut the PTFE tube so it is nearly flush with the end of the heatbreak but sticks out .5-1mm. Reasemble and you have a foolproof method with no measuring involved.

[@oricardomiranda]

You saved my printer with this video. I had a faulty tube and now my Ender 3 v2 is printing like a champ.

[@LoganCowley2112]

Thank you so much for posting this! I couldn't figure out why my extruder wasn't working, and it turns out my guide tube had melted to the hot end and destroyed it! I purchased a new hot end with the tubing you recommended and now my Ender 3 prints better than ever!

[@SilentBob1219]

Hi there, is this fix necessary if you use the Capricorn tubing throughout the entire setup? Extruder to Hot end?

[@SpacePlan10]

I think this fix with the washer ensures the cap in the hotend stays put whereas a complete length all the way still has the possible failure point of the top of the connector I.e. it can still come loose as create a gap between the end of the tube and the bottom of the hotend. You could still use cap all the way along. This fix ensures it is much less liable to coming loose.

[@bobbywhitney6262]

At the time of watching this video I don't know who were the 111 people that didn't like this video but I see there are haters out in the KZbin universe! This is a brilliant idea and thank you so much because I am one of those beginner 3-D printer novelist that loves the idea of printing in 3-D. I have been having so many hotend problems with my ender 3 V2 and was about to give up the hobby all together… But I started watching more and more of your videos and I was able to fix the leveling problems and now I have fix my hotend problem permanently! Finally, getting beautiful prints from my ender 3 V2. Now the big test is to be able to print something a little large to the capacity of the printer and that will be a true test for this fix.

[@kroberts4683]

I have done all the above, plus even changed the stock springs. I am printing a print that I have printed many times before with no problems. So it’s not the slicer. But now about 45 minutes into the print it starts skipping, not all over, just the same spots over and over. I’ve replaced nozzle , extruder, ptfe tube, springs, calibrated, changed filament, aligned bed over and over and even added a washer with the horned to keep Bowden tube close to nozzle. I’ve been living on KZbin and google for help. I’ve tried everything. Please help. I’m about to pull my hair out lol. I have an Etsy store and have many orders overdue. I’m at my wits end. Any advice is much appreciated!!!!

[@frankie.7z]

Im guessing you have taken the whole thing apart already. Im facing the same issue. I believe it has something to do with the capricorn tubing I have inside, and the PLA cant comfortably get pushed through it and then through the hotend. Skips all over the place, but when i push a bit on the extruder, it does push filament through. Sometimes it just gets stuck too though. Im going to print a new hotend insert, and will add a new piece of capricorn tubing and see if that fixes it! Let me know if any of these fixes help.

I started to thing I will never get it right until last night I searched on KZbin again and found the standard thing again. But then your video was below and I did not see that before. So I clicked on it. This morning I tried what you explained and my printer pushed out it's first print in weeks with no problems at all. Thanks what a great idea. I will have to reprint the washer though because even that came out shitty before I implemented your strategy. Thanks again.

Chep as you can see the tube fitting wont go all the way in with the printed washer, i had to carve it conical to match the dish shape of the heatsink so the hose fitting goes deeper and locks, i posted a video on the cr10 facebook group but i want to share it to you so you can do a new way to do it, i even had to reduce my flow of how well i made it work 100% sealed

[@bryantran1673]

Had the same issue while attempting this on my stock ender 3 today. I was barely able to screw the fitting onto the block and almost stripped the thread before noticing something wasn't right. Solved by by sanding down the printed washer so that it fits inside the hole and lays directly on the cut capricorn PTFE tube, and now it's printing perfectly. Might have needed to tune my extrusion multiplier and e-steps before printing that washer since I had to sand quite a bit off.

[@FilamentFriday]

Check the cooling fan. May be spinning too slow.

[@TableTopBiker]

Like Chep said, check the hotend cooling fan. You may be getting heat creep. That's where the hotend fan and heat sink can not keep up with the heat generated by the heater cartridge. Alternatively, you may want to turn your printing temperature down depending on what you have it set to. Edit: after reading some other comments, ensure your hotend fan is facing the right to direction.

[@Kl1Ainti]

Thank you both for the answers, I took apart the hotend again and the washer was completely mashed in the fitting, it's heat problem after all.

[@shrimpinpat]

Any time I need help I come across CHEP. Just wanted to thank you and hope you are making good money and getting great good perks brother. Appreciate all the help.

[@Shanjaq]

I was afraid this would happen: the funnel is too rough, the filament gets stuck on the top/outside opening of the funnel and can't get down into the Capricorn tubing below, I also noticed the washer was ~ 1.5mm smaller diameter than the extruder inner diameter threads, so it can move around quite a lot while installing. I tried assembling with a length of filament going through the top/outside PTFE tubing and sticking out far enough to force the funnel & lower/inside Capricorn tubing into alignment, which seemed to work but then I pulled the filament out and tried pushing it back in, same problem: the funnel just won't align properly :'(

[@Shanjaq]

seems I was able to resolve it by poking an awl into the exposed top of the Capricorn tube to expand it so its outer sides are touching the inside of the heatbrake, also sanding the printed insert with a small rounded file as it spins in a drill chuck (careful!! don't snag the file on the chuck, or you're going to have a bad day..!)

[@jimfallon3247]

Tried this in my Ender 5 last month. Working perfectly. I was thinking about an all metal hot end, but given they often jam up , I think I will stick with your method. Thanks.

Capricorn is a trademark. Is not a special PTFE tube.

[@grandaddy1802]

Thanks Chuck!!! Figured I'd post up my little story that was fixed by this video. In the process of doing this mod, I found a nasty booger of melted plastic down in the heat block. Had NO idea it was down there until I had both the nozzle and the bowden removed. Come to think of it, that booger was the reason why I had to crank down on the extruder tension AND increase my nozzle temps up just to get anything to print (and we won't discuss the..."quality"...). So. Now I have Luke's fix, your spacer, Capricorn bowden, a new nozzle, and a clean hotend. Using your 0.20 profile, my very next print was gorgeous. I cannot thank you enough for what you have/are providing to the maker community.

[@jamesphillipsjr]

Solid technique. This transfers the force to compress the PTFE away from the coupler teeth and instead to the (washer) coupler body. Good job on the washer bevel, that is really important. Capricorn tube is great stuff but it's always about XS. No doubt XS is amazing stuff for higher quality filament and high print temps. No one seems to mention their TL tubing. Always perplexed why TL is not used more frequently, especially on beginner and primary PLA users. TL is not quite XS specs but it has a more stock-ish ID which is more accepting of filament made with varied thickness. You can somewhat see through TL; which I find a useful feature. I am excited to try out this technique using TL in the hot end and either TL or factory Creality tube as the carrier. AKS (or other good) couplers are still a good idea to replace cheaper couplers and keep parts held tight. One meter of Capricorn tube (which ever flavor of choice) could last you a very L O N G time.

[@joemcdonough2765]

So, I am still waiting for a printer that has no factory defects when new. Like a printer that no one has to modify after it's been running a while.

[@olenorgren7915]

That would be the Prusa MK3S. There is a reason it has such a high price compared to equivalent printers. It's not that it's THAT much better than other printers, but because there is incredible support and A LOT of R&D to make it the most consistent, and beginner friendly printer there is. You might need to change the LM8UU bearings and rods after a lot of use, and a couple of nozzles. Other than that it should run flawlessly for years.

[@justbenny84]

I have done this mod on a FLSun Q5. Just had to scale the washer a little bit to fit. I printed the washer I abs to make shure it is heat resistant enough. I think one of the biggest advantage of the mod is that it makes changing the nozzle much more comfortable, because you don’t have to push the Bowden down till it touches the nozzle, which always includes a little guessing and hoping it sits flush and seals properly. And especially on a delta there is very much stress on the Bowden coupling because the Hotend is constantly moving in all axis with high speeds and jerks. So a Delta printer will definately benefit from the mod. Thx for showing this simple and effective fix!

Once again CHEP saves the day!

CHEP you are the king of Creality man! Great videos all around!!!

[@Mike02188]

Chuck this is a great idea and was part of the fix to my ender 3 headache!

[@petrusvanbreda6533]

I have done now two machines with this solution. No problems are experienced. I have redesigned the washer a little bit for my use. All in all a great solution. I have a all metal heat break and it keep in stringing, still need to try and find out why. My Micro Swiss all metal work fine and then suddenly it start to clog after a few days of print. Still not sure why. Keep up the good work and thank you.

Wow, I'll have to give this a try. I've been having all sorts of issues printing, and had to replace my hot end due to filament leakage. This is a really good idea!

Great video, your findings is always spot on with what we all go through. This video is pretty much my experience ever since I've watched that first plastic coupling video. Back then I've decided that the washer was a better solution because it was being held down by metal threads. I've been exchanging the insert every 3 months from a 5 meters long $8 creality PTFE I've ordered from banggood together with the printer (I had watched a lot of videos before buying the printer so I knew some of the necessary cheap extras to order, yellow springs, fans, nozzles, metal extruder, etc...). Just like you, I've also found out that the printable cutting jig was not the correct size, so I broke off the end stop wall, and use it mostly for the 2 walls that guide the blade for a square cut. I've measured by cutting it a little bit longer than needed, then unscrewing the nozzle 2 or 3 turns, putting the piece in, cutting little portions as needed, and when it's flush with the washer, I know that the unscrewed portion of the nozzle is extra, so it will squish when tightened. I've just received my capricorn tubing this week, ordered it in November, $48 in shipping (4 months) to Brazil, I so wished they would ship it from china (chinese shipping subsidies makes for $2-3 shipping to Brazil), I had a choice to make, keep swapping out inserts, or pay the price to have long lasting inserts. 2 meters long capricorn is a lifetime supply as inserts, since, like you, I've decided that the guiding tube would remain as the white one.

Thanks Chep!! Had a blockage and performed this fix. Have run a few prints and seems to be working perfectly now. Thanks so much!!

Hey Chuck, I have used your setup and your profiles with minor changes for a long time now with great success (so thanks for that). Couple days ago my printer starting having a really bad stringing issue out of the blue. I cleaned the dual gear aluminum extruder and made sure it runs smoothly, changed the bowden couplers, replaced the capricorn tube both inside the hotend and outside, replaced the plastic washer with a new one, cleaned out the hotend by passing a bowden tube several times through, changed the nozzle with a fresh one and made sure to hot tighten it, tried different filaments, tried lowering the temp, but I still get horrendous stringing. I have run a couple of retraction tests and it does not get much better even with extreme values for retraction length and speed. I am fresh out of ideas, so any pointers will be greatly appreciated.

[@FilamentFriday]

Try a different filament. See if it changes.

[@richardnjones2008]

Thanks a lot for this fix, it is the only thing that stopped the hot end clogs.

[@Giggino26]

Chuck you are the best! You solved a problem that i has with ender 5 since 1 month!

[@BinarySpike]

Was searching how far to screw in my nozzle/barrel after I attempted a fix for the issues indicated in this video! What luck! Thanks for the info!

[@kubik256]

The same problem on my Ender 3 last week - melted PTFE tubing inside heatbreak and after that stock extruder broke from too much pressure. I've changed whole hotend + PTFE tube + broken extruder (changed with aluminium copy = less fragile) and all is ok again., but Your tweak looks perfect for the future-proofing the printer. Thanks ;)

[@rodrigocortina]

Simply great Chuck! I am printing that upgrades using my old Fabrikator Mini, which I bought years ago thanks to you (and still working fine)
