Upgrade the Ender 3 V2 PTFE Tube and Couplers in 5 Minutes or Less

[@ksprashutv]

Hey, thanks for this vid. Question: I have a brand new v2 that I haven't assembled yet. I have my capricorn tube as well. Can I go and install this into the hotend without heating up the nozzle? Was the heating of the nozzle specifically for removing the stuck filament at the end of the old tube, or does it help with the expansion of the hoteend in order to make the assembly / fit better?

[@olafschermann1592]

You need to heat the hotend because of thermal expansion. You want the nut to sit snugg at 200 C, not at room teperatur. Sonyou should tighten it at that temp. But you can assemble it cold and make it tight at 230 C

[@RyanFribble]

I just want to say this was a very easy to follow video. Didn't waste any time, gave me the relevant information and timestamps made it easy to go back when I needed. Replacement went great except for burning myself a bit despite you specifically saying to be careful

[@chrisbyrd6012]

I just had to do this and I discovered that you don't need to remove both screws. Just remove the long screw and leave the short one alone.

[@tev2332]

@Khari Nehemiah Why do you spam this under every YT video?

[@Rob_65]

Hmm... they must have changed something at Creality. I just got my Ender 3 v2 at December 1st and guess what ... the couplers do have metal teeth. Yes, I'm sure of this. I checked with a microscope; nice and shiny little teeth in there. I also checked with a magnet and the magnet sticks to it so definitely metal. Pro tip: if you are going to replace the ptfe tube, you might also want to remove the nozzle and check&clean the flat back end of the nozzle to make sure there is no debris of plastic on there. If you don't, the problem will become worse every time you re-install a (new or freshly cut) ptfe tube

[@ayeitshanah2151]

I was so discouraged about this fix, now I’m super confident and finally ordered the parts 😂 thanks!

[@oph1066]

Great video but can you tell me what is the reason to swap out the boden tubing it came with

[@JRPW]

Causes jams when printing hotter than 220 after a while. It is not rated for high temps apparently. This was the one problem with my v2

[@timwright7738]

Awesome tip at 4:53 about leaving the coupler a turn from tight in order to get the tube shoved into the nozzle! I was desperate for a way to cut the bowden tube straight and did not have the cutter. I finally ended up using the wire cutter on my cat5e crimping tool... it really worked awesome.

[@dmitche3]

How do you get that Bowden tube off? I'm pulling really really hard and it isn't coming off. I heated everything to 230. Actually, The fitting came unscrewed very simply preheating. I can't imagine that that caused the problem with the tube not coming out. This Ender 3 V2 has been great until the past week. i've replaced the nozzle to find that my unit wasn't assembled correctly and the fan in the shroud isn't attached to anything. Fun. But now I now that the loose wood screws in it were creating the vibrating noise.

[@TheEdgeofTech]

If you can't get it off by pulling, push the tube through it. That should help.

[@jonnyreverb]

@3:28 And that's wehere I destroyed my coupler. I don't understand how anyone gets the coupler off the bowden tube without destroying the teeth on the coupler. I pulled off the blue clip, pushed down the collar, and it was stuck. I pulled, I pushed... Still stuck. I just had to force it out, and the tiny washer of teeth that grabs the bowden tube tore and came out with the tube and the collar. Now that it's toast, do I need the entire coupler, or can I just buy the toothed washer?

[@infraled]

I burned through 3 couplers in the same way. The capricorn tubing caused my filament to break at the extruder gear, because the teeth ground away at the filament especially during retractions. The couplers were trash though and I don't think you can fix them.

[@KAZVorpal]

Remove the coupler BEFORE heating up the hot end, and slide it up the tube so you only have the tubing stuck in the hot end alone. No reason to wait and risk a burn.

[@WhatIsMikeMakingNow]

Great tip for the hot end, by tightening coupler after inserting PTFE tube.

[@FaatehRauf]

Thank you for the short and sweet tutorial, This has to be the best KZbin channel for 3D Printer enthusiasts

[@TimsBitsnPieces]

Hi, There is No need to remove the small screw on the hot end cover as it attaches to the plate with the 2 side clips on it. I have used the Capricorn tubing, much better from the comments I have seen on other channels. I have just started printing with my E3V2 that I purchased just after Christmas here in Australia... thanks for the info.

[@dotnet302]

Which better better size ptfe tube if am using 1.75 mm filaments, 2mm or 1.9mm inner diameter?

[@Tschudenizer]

Thank you for the very helpful video, I watched it since I want to replace the extruder, the bowden tube and the hotend on my Ender 3 v2 this weekend. One question though: you said to make the extruder fitting tight before putting the bowden tube in and I would have assumed it should be better to first put the tube in the extruder fitting and then make it tight with the wrench? Same as for the hotend-side fitting? Or does the tube only gets caught by the teeth inside the fitting but not by tightening the fitting?

[@appalights]

Do you have to heat up the nasal to take the tube out

[@TheEdgeofTech]

You may or may not depending on how hard it is to get out of the hot end. Technically you don't, but a lot of times the tube is stuck in the hot end and it's easier to heat it up and pull it out carefully.

[@appalights]

Thank you

[@thorozar3662]

How does one remove the bowden tube from the coupler on the extruder side? Mine is very stubborn. I have this blue tubing you have, but I had a serious jam I needed to remove so I took it all apart. I cannot get the tube out, ended up cutting it off. I have no issues getting the tube out of the hot end side.

[@traceythompson546]

Love your videos! So thorough and easy to follow!

[@AdamMann3D]

I'm not trying to be creepy stalker guy, but I'm pretty sure I deliver your mail occasionally (I'm one of the subs) I'd seen your company name on some stuff I left there so I googled it. I have a not too much smaller channel than you focused on scale modeling and occasionally 3D printing as my background is in 3D. At least now I can put a face to the name.

[@skelligringphotographyandw7012]

Is it essential to heat up the hot end, if I am replacing unused tubing with upgraded tubing (in a new printer, during the build)?

[@jamesc.7988]

How are the bowden tube couplings removed from the Ender 3 V2 Neo? I'm not seeing anywhere to get a wrech on them.

[@santiagomoneta]

What is the symptom that tells you that is time to change the tuve?

[@leektah354]

2:02 No, you're incorrect. You only need to remove the screw on the right side.

[@Banthah]

Thank you so much for this. I actually used it to take my Bowden tube off so I could clear a blockage 👍

[@rickredman2788]

Will these Bowden couplers fit on the anycubic kobra plus.

[@TheEdgeofTech]

I am not sure. I don't have one to check.

[@kpj54256]

I went with the same set up from TH3D on my V2. Unfortunately after a while, (30 or so prints), the teeth inside the coupler don't hold as well as they should causing the tube to move in and out of the coupler during retraction/extrusion. :( Going to get a different style of coupler that allows the tube all the way through the coupler so that it can be widened a little and be pressed up against the tensioner bracket to stop that from happening.

[@BenMilford]

Did what you tried work?

[@perflygare5751]

Hi Jim and everybody, I am completely new to 3d printing but not designing. About ten days ago (after a long time pondering and asking question to a friend of mine who is deeply into 3d printing), I ordered my E3V2 (that's what I call this unit) directly from Creality. Along with that I also ordered another glass plate, but also the Tungsten nozzles and the upgraded Belt tensioner don't know whether it was necessary but I got them, total price 295 US dollars which included free shipping. Another purchase I did was to get was the gear extruder upgrader (to aluminium) and bed springs. Looks like I should consider this upgrade as well while building the printer. This printer will be used along with the software of Fusion 360 and SketchUp (latest version) and Cura. The printer will have a separate dedicated desktop only to be in this setup. I am trying to get the needed upgrades before building this unit - your input will be helpful. Thank you all!

[@Koolkole27]

I had cut my tubing short over time so I dont know what it originally was for length when i bought the printer!!

[@joshbarnhart6714]

Your videos are awesome you're the only person that covers the v2 Any future videos on replacing hotend cooling fan I have a broken blade I think I can change the wiring out on the board but not sure I'm new at this had my v2 for about 3 weeks

[@NoxiousCEB]

I found out that the original PTFE tube that's shipped with the printer has a wider hole than 2.0mm and by replacing it with a 2.0 one made my printer skip extruder steps, underextrude and clogged the end of the PTFE tube, due to the retractions and the end of a PTFE tube not being wide enough. One could think, that this TH3D PTFE 1.9mm would produce the same results.

[@CNDFireFighterPilot]

Awesome, extremely clear video!

[@vargaslc2]

How is this tough tubing different from Capricorn tubing?

[@JasperJanssen]

I imagine it’s cheaper.

[@joekrinkey8355]

It's rated for higher temp.

[@puriap250]

Why does the hotend have to be heated for this?

[@emanuelpruker763]

Hi there, can a new ptfe tube cause stringing? the lenght is the same.

[@TheEdgeofTech]

It is possible, if it's not pushed all the way down to the nozzle. Also you want to calibrate after replacing for PTFE tubing. Make sure the flow is the same because if it's a better than stock PTFE tubing it could be sliding better and causing more filament to come through. Then the stock PTFE tubing did.

[@emanuelpruker763]

@@TheEdgeofTech Can you point me to a tutorial for calibration?

[@emanuelpruker763]

checking back, my stringing is driving me nuts. made a calibration cube and it's ~20.06 in every side. (i think it's good)

[@DavidJNowak]

Why should we do this? Is this just to change the color of the tubing?

[@a7xfanben]

I only needed this to unclog some PLA while changing out spools, but this was very useful as a new Ender 3 V2 user! :D

[@fluffysideup205]

I had the same issue and came for the same reason lol

[@MeshJedi]

Doesn't this make it impossible to get filemament out of the tube when it breaks or runs out out of the roll? Also what temperature does the rough tubing handle? Capricorn doesn't handle any more than regular, just closer to the filament diameter inside.

[@TheEdgeofTech]

It's rated up to 275C but only recommended up to 260c before off gassing starts the PTFE. It's pretty easy to get it out when it breaks inside, you just push another piece through it and it comes out. :) Thanks for watching!

[@MeshJedi]

@@TheEdgeofTech Then you need to push a whole ptfe tube length of filament through the nozzle though. You can't just print with a new filament pushing form behind since it won't retract

[@giroadster]

On the back of the shroud, isn't the left screw a fan fastener that does NOT need to come off? On my V2 (same machine as in the video), only the one on the right needs to be removed for the shroud to come off (with the fans). The left side of the shroud is only secured in place by 2 plastic tabs. All this is in REAR view of course, like in the video.

[@SirQuacksalotthe1st]

So can I print abs after this ?

[@dariocalidaro]

Hello, could you please be so kind as to provide me with your parameters regarding retraction distance and retraction speed?

[@m0cha908]

You just helped me from having a mini heart attack after my PLA got stuck in the tube after it got gnawed in half after the PLA got wrapped up (no spool because it was the kind that came with the machine)

[@dalewhitmore143]

So what can we bump up print temps to now if running marlin? 300?

[@aiph4761]

A bit late, but why does it matter that the tube is the same size as the default PTFE tube? Doesn't it just need to feed it into the hotend?

[@gene_Code]

Why can't we just super glue the bowden tube to the coupler?

[@TheEdgeofTech]

Because the parts move and need to be removed if necessary. :)

[@perflygare5751]

Never use superglue with the combination of heat! It's a direct fire hazard and the fumes that are coming long before are extremely bad for you.

[@geoffmaxwell4461]

About to blow your mind... only the right screw on the back of the hot end needs to be removed :)

[@richardgoone3438]

Thank you Sir, Saved me :)

[@Divyanshu.17-h6q]

I tried to pull out ptfe tube from coupler with full strength but they are just locked in it. I have detached tube from both ends, but those stupid couplers not coming odd

[@3dyour2a59]

The first thing you said take your old coupler out and "this is the same if you have the upgraded extruder or the plastic one" then when you say to put the new one in you say "grab the one with the small threads"... I've got the upgraded extruder and there is NO WAY the coupler with the small thread will fit in my the female threaded parts would swallow the whole coupler.... did they send me the wrong part? After I just installed this double geared extruder?!

[@kevinjones6924]

Awesome info thanks! Do you not have to put the little plastic coupler clips back on before assembling the fan shroud and on the extruder end?

[@TheEdgeofTech]

Are you talking about the little C clips on the coupler? If so, I dont, but you can if you want to!

[@kevinjones6924]

@@TheEdgeofTech Never had issues? I never really understood the use for them if you're the only one that uses it. 🤔

[@TheEdgeofTech]

@@kevinjones6924 I haven't had issues with these replacements, but yes I do use them with the stock ones.

[@JasperJanssen]

@@kevinjones6924 without the clips, the plastic part of the coupler can move back, if the tension is let off - say upon retract - and that makes it hard to retract (adds a mm or so of retract you need to do), and also the continual movement can lead to failure of the coupler.

Time for this upgrade. 🤞 Just finished the upgrade. Most important is making sure the hot end is the following: 1. Make sure the hot end coupler is tight. Then loosen like 75% ish 2. Bottom out the hot end tubing. THEN tighten the coupler down and it will push the tubing down farther!!!

@k C137 Is it the clips on the right hand side that a causing it not to remove? You only have to remove the longer bolt, then you have to swing the shroud, and gently coax the 2 clips on the right side off. It took me a few minutes to do it, but I let the hot end cool off so I didn't burn myself, but like you, my machine is only a few weeks old, so these clips were holding really well!

Nice video again on the Ender 3 V2 - I did a similar update to mine with the Capricorn brand tubing - looks the same stuff with the TH3D kit (same distinctive blue colour)

Pretty close, but TH3D Tough Tube is rated for a higher temp. Either way, it would be a good upgrade from the stock PTFE tube.
