do THIS before troubleshooting stringing on an ender 3

Also check Bowden tube at hot end to make sure it’s not burnt. Regular nozzle changes are critical as well. I learned all this the hard way!

How do I get the Bowden tube out, I was pulling very hard

@@vanhelzer22can you still explain it tho?

[@vanhelzer22]

@@Bananagogoyeet the Bowden tube connectors are are a two part assembly. The plastic (part#1) piece sitting on top of the metal connector (part#2. Press part #1 down against part #2. You should feel a click. Keep pressing the two parts together then pull up on the Bowden tube. It should come right out (provided that the hot end is at operating temps). Look for a burnt end on the Bowden tube. You can then check to see if the filament is binding inside the tube(makes it super easy to check if you have a knob on your extruder).

I wish I could've seen this when I was new to 3D printing, had this same problem and wasted about 9 months of time and about $70 in equipment. My logbook was a mess. I didn't even notice until the threads of the coupler were showing because of how loose it was. Man did I feel stupid then lol. Thanks for getting this tip out there, hopefully it helps people who are luckier than me 😂

[@Rduino]

So simple no one thinks of it :)

[@novenadvanced9020]

I’ve seen this many times but it has finally become useful to me

[@Rduino]

happy to help :D

[@clxvd_official]

Thanks so much just changed Bowden tube and forgot to tighten this up

[@justinaguayo8833]

Lol😂 you can’t be serious! Why is this not the beginning of every stringing video. Could have saved me time and money

[@Rduino]

6 hours of troubleshooting man, all bc I forgot to tighten the nut

[@kevinpunk2006]

I'm guessing because I replaced the nozzle when the machine was still heated up. when it cooled down it became loose because the metal contracted. Thank you for the tip my friend :-) I will make sure to double tighten when the machine cools down from now on!

[@Rduino]

Glad I could help 👍

[@kevinpunk2006]

@@Rduino Do you have a video or any tips on printing with petg? I figured that I would try it out and its super stringy and or fails, usually on larger prints..I'm using the temp suggested on the roll but 1ºc hotter. I have an ender 3. any help would be greatly appreciated

[@Rduino]

@@kevinpunk2006 did you dry your filament using a dehydrator?

[@vladislavcaptari2131]

I just so happened to lose that coupler during assembly but thought it would be inconsequential. My face when my first prints had stringing / feeding problems. I'm new to 3D printing so I don't exactly know where to find hardware for these printers. Mine is an Ender 3 Neo. I hope I find it soon.

If you are in the us: amazon www.amazon.com/Creality-Capricorn-Filament-Extruder-Fitting/dp/B09GM6W972/ref=mp_s_a_1_8?crid=3CQSNQ4R9JG2K&keywords=ender+3+neo+bowden+tube+coupler&qid=1693411641&sprefix=ender+3+neo+bow%2Caps%2C190&sr=8-8 this includes the couples you need and it also includes better tubing. It would cost $10 for a bunch of couplers or this so it's your choice if you feel you will loose them again. Cheers!

[@sebastienp9141]

Also in Ender 3 Neo, can't print anymore with Amazon PLA or original Creality PLA (sliding on the bed 😢)

[@Rduino]

@sebastienp9141 the plastic doesn't stick to the bed?

[@stickboyfpv4742]

Also print the piece to install the extruder motor right to the head🎉!🤗

[@Rduino]

That is called direct drive, it has some advantages but I personally don't want extra weight on my lrint head.

[@stickboyfpv4742]

@Rduino correct😆 I got the dual z for $28 on prime day... so I had to do it!🤗 I cant really tell a diff on pla.... Did it to print tpu better... but havent thrown that back in yet😬

[@cdawson198600]

Wow, that's more like weaving some serious stringing.

[@kevinpunk2006]

I hope that's exactly what's wrong because I was printing perfectly fine until I got a clogged then I unclogged replace the nozzle for the fun of it anyways and clipped the end of the Bowden tube but now it's stringing and I hope that what you're talkin about is causing it

[@Rduino]

any luck?

[@diminacomusic7070]

i love you and hate you XD damn wood pla had me chaseing clogs for underextrusion, and even after a cold pull normal pla still was way underextrudeing...pro tip bro. earned my sub

Wood pla here too :D

In situation of Buying 3D printer from someone for the first time , What should i have to check first to confirm that it's Not faulty ? Can you suggest what should be the test print to Check it's Performence and Quality ? Like Hello world for the 3D Printing ?for ender

[@Rduino]

[@Rduino]

also, if you buy a 3d printer off someone, don't expect it to run perfectly. The print might look like crap because it needs tuning. This is normal.

What millimeter wrench

[@williamangeles9761]

Thank you so much.😂😂😂

Happy to help :D

[@ghostofanoble9708]

I have this issue as well but have tightened the bolt down as tight as I can get it, but my printer looks like it’s still only printing the first few layers then proceeds to stop printing all together any tips??? I had also cleaned out the nozzle

[@Rduino]

That sounds like an extrusion or heating issue. Is the extruder grinding the filament?

[@ghostofanoble9708]

lately yea, i thought it might have been a hardware issue so i replaced it but its still grinding the filament a bit@@Rduino

[@Rduino]

@ghostofanoble9708 pull some slack from the spool, does it continue to grind now that there is no tension?

[@ghostofanoble9708]

I believe it helped a bit, but i always seem to run into an issue once im a quarter of the way into the build, then the extrusion gear wears into the filament@@Rduino

[@ghostofanoble9708]

and just grinds the filament and causes issues

[@LnD0nC00lZz]

Lol happened to me too

BAMBUUUUUUUUUU🗣️🗣️🗣️🗣️🗣️🗣️

[@keetguy]

what is that tool called?

[@Rduino]

A wrench. You could use a socket wrench or adjustable wrench for this. The One I used cam with my ender

[@ScarySkeletal]

Cool but why when I'm preheating somthing the filament keeps coming out like its trying to print

[@Rduino]

That is just filament from the precious print reheating. If you preheat to a lower temperature and then hit print there should be less dribble.

[@ScarySkeletal]

@@Rduino yeah I figured it out and im getting successful prints i was pissed off when I was commenting ready to break my ender 3

Play around with your temps and print speed

[@smolrobyn6042]

so, theoretically, if that came unscrewed, and say in this theoretical, it wont screw back in, theoretically, what should i do?

[@Rduino]

are the threads on the coupler or the hotend stripped?

[@smolrobyn6042]

@@Rduino nope. its just fully unscrewed and wont go back down. imma try removing the pipe tomorrow and then screwing it in that way, should be easier

I know I'm a lot late, but for anyone seeing this in the future, simply fully remove the PTFE tube, put the coupler in, then feed the tube through.
