You saved my machine from the crusher.:) Thz. Great presentation.

great !!! thaks!!!

Thanks a man!

Josh you my hero! Thank you!!!!

Very nice video, good job!

i accidentally doing cold pull before ,i thought the nozzle is not clean enough..thanks man

Thanks!

hi , great video ,what software did you use to make the stl file change as it looked really good to use. thanks

this is hentai

Awesome, next best thing to a glass nozzle. Maybe a ruby one?

Thanks for this.

Now let's see a print like that 😂

Man I love split views of things working. :)

Very cool

is there a better model of hotend?

Why don't you ever say the size of the tube you used

Tks 4 sharing

Your photography was excellent and very helpful. Your explanation was really easy to understand! Might be the best of hundreds of 3d printing videos I've watched!

great! thanks a lot. it works perfectly

A truly amazing video!!

This help me fix my jamming issue. I couldn't get pass the first layer. What I did was trim the dirty part of the tube and follow this assembly video. Also did a cold pull after assembly.

I had an energy 5 . Problems with hotend and upgrades . The enders are not good printers . They get the most coverage for a cheaply built product. The real good printers dont need 100s of videos on how to constantly fix them. Please stay away from the enders

👍👍👍👍👍

Just buy a standard genuine Festo coupling instead, the Chinese ones have crappy grippers...Worn out tooling leaving blunt gripper edges in the coupler...Typical Chinese lack of QC.

Is it 12v or 24v?

What connectors do you use for your heater cartridge DuPont there?

Thanks that help me a lot on fixing that problem.

This looks like it would fit my Geeetech A20. Does it work with other filament like carbon fiber or just TPU/soft filament?

I had trouble with my cr10 since new and struggled for ages and gave up. Turns out this was the problem all along. Well done

My PTFE tube is not tight. It wobbles around in there. I bought a new blue capricorn tube for a 1.75 filament. I`m not using the stock white one. That could be the problem, maybe the outer diameter of the capricorn is smaller than the default white one that comes with the ender 3

brilliant - thanks - lovely cutaway! Obviously, onebadmarine has a great mod documented here in the comments (www.thingiverse.com/thing:3203831).

Fantastic example!!!! Thank you

This fucked me up a whole bed of printed pieces. Thanks for the effort and explanation.

This use to be common on push fit water line connectors. I always held them tight and persuaded it to catch, not that it would work on these...

123d Design, haven't seen that in a while. I thought I was the only one that still has a copy. It was available on Amazon, was.

If I never printed with TPU this is one of the most informative extruder videos I've watched. Thanks.

It's exactly what stopped me from printing in PLA for years. Once I purchased an Ender 5, a Micro Swiss hot end and a Capricorn tube, held the PTFE tube down hard as I pushed the 2 coupling locks on I was finally able to print in PLA. Because of the constant, never ending problems it created beforehand I absolutely hated PLA (never happened with ABS) and refused to use it. I was apparently foolish in saying PLA was an outrageous, unreasonable problem for me because the only reactions & responses I was given were intentionally insulting to me and accused me of things having no relevance to as much. I'm not homosexual but for some reason many used that in their responses to my statement of my problems with PLA. Micro Swiss & Capricorn fixed the PLA issue.

Almost 4 am in the morning and i can't sleep trying to figure out why I can't install my bowden tube correctly despite trying every guide I've found. Thanks for this video because now I finally know why nothing is working and I can finally rest

Nice job, I've been having the same issue with my Ender 3... I leave the nozzle loose, about 2turns.. Then install the tube.. Then , ,when I tighten the nozzzle, it butts right up against the tube... But , occasionally, it screws up..

Same problem occurs with short 7mm throats that accept the bowden tube directly into them. Been struggling with that for a week since I can't find 6mm heatsinks that fit the 6mm throats anymore.

I just drilled out the stock extruder and fit the ptfe tube in there. works great for tpu

What a great video. This must be my problem. I've had deterioration issues with my prints and a strange phenomenon where I cannot retract my filament to change filament, but I can push it through. Making me push through an extra 20cm of filament or small print to change to a different colour filament. I knew this was some sort of a block, but I think I'm not clearing out the nozzle properly by putting the PTFE tube back in correctly. So re-creating that same gap, and always causing that block.

This explains my troubles 👍

Do you own a lot of printers with Creality hot ends? Yo must because otherwise I call shenanigans on all those similar colored plugs....

If you do get a plug formed, what's the best way to get rid of it?

If you seat the tube before the nozzle you can achieve a tighter bond between the nozzle and the coupler and the ptfe tube, when the tube pushes back to lock it in place. the only downside is making sure the ptfe tube is cut square to the coupler and not pinched, I have found using a short piece of filament when cutting the tube will stay round and not change the center of the tube weather you use a knife or cutters.

I hope this fixes my problem. My first 5 prints came out just as expected, but then when I went to print again, it wouldn't extrude and the gear would pop/slip. At first I thought it was my bed leveling. I tried releveling it a few times but that didnt work. I finally took the nozzle off and found one of those blockages. I thought that would fix the problem but when I went to print, it did the same thing. Maybe it created another block while heating? Any ideas?

Thank you!

Absolutely amazing explanation ! thanks a lot for share your knowledge !

Love the visual. This topic has been covered to death but you did it in a refreshing way. Thanks!
