Authentic Capricorn PTFE Bowden Tubing (1 Meter) XS Series for 1.75mm Filament with PTFE Teflon Tube Cutter and Upgraded PC4-M6 and PC4-M10 Pneumatic Fittings with Metal Teeth and 2 Blue Collet Clips

Try and push the tubing as far as you can into the pneumatic coupling, and if that doesn't work, I would recommend upgrading to Capricorn tubing and higher-end couplings for $15 dollars.

DO NOT BUY THE CAPRICORN LINKED ABOVE! the brass colored fitting shown doesn't have teeth and the tube will continue to slip. Buy this one, trust me I've bought both...

It's the right tube, good stuff. I got this kit and it works well for me

Authentic Capricorn PTFE Bowden Tubing 1 Meter XS Series for 1.75mm Filament with PTFE Teflon Tube Cutter and Upgraded PC4-M6 and PC4-M10 Pneumatic Fittings with Metal Teeth and 2 Blue Collet Clips

This is what I purchased for the bowden.

Here's one. There's a number of other kits that are cheaper/ more expensive but this looks like the best bang for the buck. https://www.amazon.com/Authentic-Capricorn-Filament-Upgraded-Pneumatic/dp/B07PS3NH82/ref=mp_s_a_1_3?dchild=1&keywords=capricorn+ender&qid=1590291570&sr=8-3

I'd also recommend checking out the r/ender3 sub and taking a look at their beginners guide. There's a slightly more comprehensive list of good upgraded parts hiding in there.

I use https://www.amazon.com/dp/B07PS3NH82?ref=ppx_pop_mob_ap_share

The only times I have had to was when the tube ends melted and when the tube tore out of the coupler.

Check out Capricorn, their bowden tube itself is also a higher quality, and they send the proper couplers. Attached a link here. https://www.amazon.com/dp/B07PS3NH82/ref=cm_sw_r_cp_apa_i_6FtDFbJCA2S8Z

My only hold up on these would be the nozzle sizes I really don't need, however, I'm finding a lot of the brass nozzles seem to be manufactured by the same company - they seem to be the same. Your URL has almost 200 reviews, so they could "true", however, I seem to return a LOT of 3d printer stuff to Amazon, there is a lot of garbage, and Amazon now hides any review below a 2 star, or at least mine are. Some days I think trying to print 3d Gcode is magic.. This may not apply top you, however, I just found out the in CURA 4.4.1 at least, the fan settings will not change when changing materials. ABS=Fan off, PLA = Fan 100%, however, when you select PLA, it doesn't change it - DOH! Some how I'm not conveying what PTFE is, the Blue Tubing here is what PTFE (Teflon) tubing looks like: https://www.amazon.com/gp/product/B07PS3NH82/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Some days messaging just isn't helpful when trying to pass information. I really have only printed 3 benchey's, I normally print the Pig that came on the SD card, gives me a good sample print for color comparison.

I just had to replace the pneumatic coupler because the Bowden tube kept coming out on mine. I ended up replacing both couplers and the Bowden tube.

This is what I ordered for my Ender 3 - Authentic Capricorn PTFE Bowden Tubing (1 Meter) XS Series for 1.75mm Filament with PTFE Teflon Tube Cutter and Upgraded PC4-M6 and PC4-M10 Pneumatic Fittings with Metal Teeth and Blue Collet Clip https://www.amazon.com/dp/B07PS3NH82/ref=cm_sw_r_cp_tai_oKu8EbTZ4QGC5

Then I ordered a few spare couplers from AliExpress.

Why was the rating for the tubing I bought explicitly rated for 300°C? *Edit: This is the link https://www.amazon.com/dp/B07PS3NH82/ref=cm_sw_r_cp_apa_i_xNXOFb7DEHHPX?_encoding=UTF8&psc=1

Get This. I had the same issues as you, until i installed this tube. Just make sure the tube sits flush in both endings.

Replace the tube and coupler with new ones. Some are trash. I use Capricorn bowden tubes like this. Check to make sure these couplers fir your printer.

I'm gonna link you specifically what I bought. Its not an endorsement or an advertisement, and I can make no guarantee that you'll have the luck I did /legal disclaimer.

I used this extruder https://www.amazon.com/gp/product/B07J44QW8B/

and I used these springs https://www.amazon.com/gp/product/B07FY47BX7/

The reason I'm suggesting this over the combo kit that you linked, is that I like having the extra springs.. Primarily because I put one of the bed extra bed springs in my extruder instead of the extruder spring. Its worked fantastically. Also I prefer amazon due to the better and hassle free return policy if anythings funked up, and the more local shipping (days instead of weeks), the same goes for sourcing the printer.. Creality has awful support.

Capricorn Tubing I would consider a nice to have, but in no way essential. Bowden tubing does wear out over time, so you will need to eventually replace it, but I wouldnt consider it essential to do it immediately.. Especially if all you are printing is PLA.. but if you are looking, I would get the kit like

https://www.amazon.com/gp/product/B07PS3NH82/

It comes with better bowden couplings, and tube cutter to give you flat cuts (Which are very important so plastic doesnt ooze out between the bowden and nozzle)

I would still ultimately suggest the Ender 3 Pro over the V2. Especially with the sales that have been popping up lately where you can get them for like 200.

Capricorn Tubing

All Metal Extruder

Just the pressure of the spring against the arm and the jog wheel against the stepper motor, repeated action just fatigues the plastic and it eventually fails. Do yourself a favor and just but the $10-$12 replacement and for about $25 total you can get the upgraded ptfe tube as well

Extruder: https://www.amazon.com/dp/B07B96QMN2/ref=cm_sw_r_cp_apa_i_ZS5cEbJ3YZ4YS

Ptfe tube: https://www.amazon.com/dp/B07PS3NH82/ref=cm_sw_r_cp_apa_i_GU5cEbA8QYD94

I don't think the motor is the problem. Mine was skipping as well and I solved the problem by upgrading the bowden tube. https://www.amazon.com/Authentic-Capricorn-Filament-Upgraded-Pneumatic/dp/B07PS3NH82/ref=sr_1_2?keywords=capricorn+tube&qid=1580175994&sr=8-2

Just get a new tube. It's hard to cut the tube at a 90° angle without the right tools. The stock tube fittings are crap as well and I suggest you change them too. I replaced mine with this one from Amazon - https://www.amazon.com/gp/product/B07PS3NH82/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Works great so far!

Winsin dual gear extruder, a capricorn tubing kit and some yellow springs.

https://www.amazon.com/dp/B07SY745CF/ref=cm_sw_r_sms_apa_i_1ipkEbE8N6F5Y

https://www.amazon.com/dp/B07FY47BX7/ref=cm_sw_r_sms_apa_i_okpkEbQM9MFN2

Great upgrades to start with. If you want to simplify a bit get a single gear extruder and re use the old extruder gear so you don't have to mess with the e steps.

What do you mean by later skipping? Can you post a pic example?

There are numerous sizes and threads of ptfe fittings. They are a common part use for air lines and industry.

. So you should search for ones for the E3. They should not be hard to find. I think some 3rd party extruders and hot ends may differ in the thread/size .

I think I found an 'assorted ender 3' parts pack on Amazon last year I got mine from. Had fittings, set screws, and other odds and ends.

Good luck.

These are the ones I bought and they are working perfectly.

I also recommend Capricorn Bowden tubing with better fittings like:

PTFE tubing alone

https://www.amazon.com/dp/B07XXRVGP9/ref=cm_sw_r_sms_apa_i_QHg6EbPV6GE6E

PTFE tubing + upgraded push fittings (nice to have)

https://www.amazon.com/dp/B07PS3NH82/ref=cm_sw_r_sms_apa_i_OIg6Eb8XERFNC

All metal hot end (only necessary for more abrasive materials with higher process temps like CF nylon) . Good future proofing upgrade

https://www.amazon.com/dp/B0789V2D7C/ref=cm_sw_r_sms_apa_i_LJg6EbZ54796T

Upgraded bed springs (nice to have in general)

https://www.amazon.com/dp/B07GXC1G2B/ref=cm_sw_r_sms_apa_i_dLg6Eb2RBPPWF

As for settings, off the top of my head (not by my laptop) I usually print 240-250 nozzle, ~80 bed, 60 mm/s print speed, low retraction like 0.1mm, low part cooling for structural prints, max part cooling for models (use PLA instead?)

Hello everyone, I recently acquired a second hand ender 3 3d printer and the first few prints were somewhat decent. After about 3 prints, I encountered clogging which is pretty common in stock set up.

​

I replaced the stock PTFE tubing with Capricorn PTFE tubing/coupling combo. I also replaced the nozzle, heater block since I noticed that the original heater block was cross threaded making it almost impossible to reattach the nozzle. I also did the Luke Hatfield hot end fix using 2mm spacer since I feel more secured having more threads on the coupling. The motherboard has been upgraded to the SKR e3 mini 1.2v recently updated to the 2.0.6 firmware.

Here are the parts that I bought to replace these things:

https://www.amazon.com/gp/product/B07FTHJJQ8/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

​

I'm currently using Cura as my slicing software since i've heard good things about it. Im using CHEP V4.6x profile to do my prints. After noticing a lot of stringing, I did a bit of research and found that tweaking the retraction distance/speed could help with stringing. Here are the retraction distance/speed that i've tried

4mm | 25mm/s - Stringed

5mm | 25mm/s - Stringed

6mm | 25mm/s - Stringed

6mm | 45mm/s - Stringed (CHEP's preset)

4mm | 50mm/s - Stringed

5mm | 50mm/s - Stringed

6mm | 50mm/s - Stringed

6mm | 60mm/s - Stringed

​

Does anyone know what's going on? If you need me to provide more information, let me know! Any suggestions are welcomed!

​

PS: All the prints are using Hatchbox PLA at 200°C / 60°C

You can buy a prusa for around that, or go for an ender 3 (linked below) with the following upgrades:

https://www.amazon.com/dp/B07BR3F9N6/ref=cm_sw_r_cp_apa_i_J7hHFb6AY54QX

https://www.amazon.com/dp/B082PC59BP/ref=cm_sw_r_cp_apa_i_j8hHFbW1V1289

https://www.amazon.com/dp/B07QDV7ZVJ/ref=cm_sw_r_cp_apa_i_G8hHFb7SXJCAW

https://www.amazon.com/dp/B07YMHS2XN/ref=cm_sw_r_cp_apa_i_2.hHFbG7TH0JF

https://www.amazon.com/dp/B08G1BN1BK/ref=cm_sw_r_cp_apa_i_1aiHFbCJWVK23

These are all not necessary upgrades but essentially turn the ender into a prusa quality printer (or better).

And if you want to go crazy you can go to printermods.com and check out their adaptor sets that allow you to stop using v rollers and instead use linear rails, some say it's marginal I think it's worth it.

So I have an Ender 5 with this set up

https://www.amazon.com/gp/product/B07ZPCBD5N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The only modification I've made to the base model it is to install a BL Touch.

To fix the issue I replaced the Hot End.
https://www.amazon.com/gp/product/B07R38J9Y5/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

And the Bowden Tube
https://www.amazon.com/gp/product/B07PS3NH82/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

The only test I ran afterwards was to calibrate my Z steps
https://youtu.be/xzQjtWhg9VE
And manually checked my levels.

Hope that helps

Here are some that made a big difference in my print and others which help with organizing the printer.

1) Better fan shroud:
https://www.thingiverse.com/thing:3373828

Print this sucker super fine, like at least 0.16 layer width.

2) A dual geared extruder:

https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF

Note, to install this you need a small spacer to push out the filament run-out detector. I may post one on thingiverse but at the time I had pulled apart my printer so I crafted one from wood.

3) Capricorn tubing (mostly for the better compression fittings but the tubing helps a bit too)

https://www.amazon.com/Authentic-Capricorn-Filament-Upgraded-Pneumatic/dp/B07PS3NH82/

Optional 4) Strain relief on the hot end cables:

Optional 5) Strain relief on the bed cables:
