WINSINN Dual Gear Extruder, Works with Creality Ender 3 CR10 CR-10 Pro CR-10S Tornado Upgraded Aluminum Drive Feed for 3D Printer 1.75mm Filament

It's most likely what's known as filament skipping. Reducing printing speeds can help with this. Also as a temporary fix if you have too much tension you can disassemble that extruder and remove the spring holder from the screw on the tensioner. It's that little thimble looking piece in the spring. This will slightly reduce the tension and may help.

Though the stock ender 3 extruder is terrible. I have had many failed prints due to that gear stripping the filament, so I would argue replacing that extruder is one of the more important upgrades I've made.

Here is what I bought for my two ender 3s and it has worked very well and I haven't had a failure since. Just make sure you recalibrate your steps/mm after installation. https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF/

I got the winsinn dual gear extruder. Working like a champ.

BMG is reduction geared, meaning can produce more torque and finer control. Reduce chance of underextrusion

You want one like that but dual gear. This is the one I use and it’s been great https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF

CHEP on YouTube has a good video on how to install it and calibrate your esteps afterwards (you need to do this)

I'd spend $5 more and go dual gear

I wouldn’t use the glass sheet until I had to. The mag bed on the pro is great for a while. Below is an extruder upgrade but I wouldnt buy it until your existing extruder fails. Also you need to adjust esteps for it.

Dual Gear - WINSINN Dual Gear Extruder, Works... is what I went to.

I would suggest it, so I am :)

Good catch! FYI there is now a geared version of the "metal extruder". I have not run one yet but I like the idea behind it and its a lot cheaper than most geared extruder options.

Here is a link to it.

I had one of these and it worked really well but the plastic broke the the bearing goes onto. I switched to this and it hasn’t given me any trouble and I had it running a 1mm nozzle for a while.

https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF/ref=sr_1_1?dchild=1&keywords=winnsinn&qid=1592666058&sr=8-1 I bought that one and I noticed less stringing in almost every material

This thing?

Here is the one that I picked up. You can find the same one on AliExpress for much less.

BTW, I actually upgraded past this one to a BMG clone. That is one of the best extruders out there. I wish I would have know about the BMG earlier and I would have skipped that one entirely.

I’m just now seeing this I apologize. It’s the dual extruder on Amazon. And I didn’t change any settings besides speed. This is the same Gcode I always use for PLA. Extruder

Wonderful company. I personally only run their dual gear. Excellent grip and no bite marks.

You can try turning the voltage up a bit and perhaps try to print at a cooler temp. I would replace that extruder soon.

I use this one and have zero extruder problems. https://www.amazon.com/gp/product/B07SY745CF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

It doesn't say anything about a 3:1 ratio but this is the one I purchased. https://www.amazon.com/dp/B07SY745CF/ref=cm_sw_r_apa_i_biFSEbGPX8B7Z. I think it's a clone of a Bondtech dual gear drive so I'm kind of hopeful.

I always have hated the stock feeder. It for me worked for like 3 months then I have feeding issues. The dual gear extruded has helped me significantly and I feel gives a better print when dialed in

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

I have a corexy and used to use a BMG with a bowden tube. linear advance basically does small retractions at junctions, so the extruder will be making a lot of small retractions. The k factor for bowden tubes is much larger than direct drive. Printing will be much slower because of the time taken to do the retractions. Increasing the jerk for the extruder will speed things up but extruder motor will be driven like crazy when using the BMG since it is geared 3 to 1 and it make alot of noise if you are not using a silent stepper drive. I replaced my bmg with a non-geared dual drive extruder https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF/ref=sr_1_4?crid=1KG971HP9CDE7&keywords=dual+drive+extruder&qid=1581601890&sprefix=dual+dri%2Caps%2C153&sr=8-4 and used tmc2109 and it works fine.

Sounds great that you got it maybe fixed, also that design does sound pretty terrible.

I went with a dual gear extruder instead of the normal single gear one, and I haven't had any of the issues you are referencing. Everything is super solid. CHEP has a video on his channel about how to install it if you decide to return yours or just junk it.

Metal, two gear extruder. Here is a link:

https://www.amazon.com/dp/B07SY745CF?ref=ppx_pop_mob_ap_share

Unfortunately, youll want to upgrade that to a dual gear for likely around the same cost. That one is just a metal version of the ender 3 plastic one, this one uses a different drive system to push filament so you can get more retractions without deforming it or destroying it. https://www.amazon.com/gp/product/B07SY745CF/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

Not sure where you get this from... I don't need an enclosure for PETG all day in a bedroom that has a hvac vent near it.

This is a extrusion/temp/speed issue. OP needs to tune Esteps for PLA, then do calibration on flow per filament type as each type/manufacturer is different. and temp needs to be around 230-250c depending on stringing. PETG also likes to run a bit slower than PLA at times, but I generally run at 60mm/s

I ended up at ~88% flow for PETG when esteps is calibrated for PLA w/ the metal extruder like this one: https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF and a micro swiss all metal hot end (but the hot end is not required - it does make it easier)

Crazy bang for your buck

Among many issues I had with mine out of the box, the biggest issue was that the Vrefs for the stepper motors were set to the values for the 1.1.4 board instead of the 1.1.5 board. (And they need to be MUCH higher to function reliably).

Thanks to some help from this group, I reset mine and my print is finally printing again!

Here are the values I used:

X: 1.313

Y: 1.409

Z: 1.272

E: 1.436

Additionally, I find the "upgraded" extruder gearing that comes with the E5 pro to, how do I put this politely... suck ass. So I upgraded to a dual extruder gear setup (Bondtech clone) and I haven't had an issue since. ($14-15 on Amazon) The kit includes no instructions, so pay close attention to your current setup (adding in the missing cap, obviously) and/or find a video online.

WINSINN Dual Gear extruder I've been using one for over two months and I've had no problems.

I have been having good results with 6.0mm at 25mm/s. that's with Capricorn tubing and this dual-drive metal extruder. Stock hot-end and nozzle.

Do you think that this would be a better choice than the dual extruder? WINSINN Dual Gear Extruder, Works with Creality Ender 3 CR10 CR-10 Pro CR-10S Tornado Upgraded Aluminum Drive Feed for 3D Printer 1.75mm Filament https://www.amazon.com/dp/B07SY745CF/ref=cm_sw_r_other_apa_i_zo71EbBWX0764

Going metal is a safer bet thanks to the filament cutting a groove in the plastic lever on the stock extruder and it can't easily do that to the metal one. As for the extruder I got a WINSINN dual gear extruder but before that I had just a normal red single gear extruder. The single gear worked okay but with a all metal hotend (Microswiss) I kept on getting bad extrusion and I kept hearing the wheel click on the extruder. I decided to go with the dual gear (I had to turn my steps to 141mm) but pretty much all the parts in it are metal and it really pulls filament. It was a good choice.

Have you tried replacing the Extruder with a dual WINSINN Dual Gear Extruder, Works with Creality Ender 3 CR10 CR-10 Pro CR-10S Tornado Upgraded Aluminum Drive Feed for 3D Printer 1.75mm Filament https://www.amazon.com/dp/B07SY745CF/ref=cm_sw_r_cp_api_i_.QuwFbTD4028D gear model? That solved a lot of my problems.

SKR Mini E3 -> I cannot recommend this enough.

Glass Bed

Dual Gear Extruder

All of these are cheaper on Ali or Banggood but the most recent one, I needed them quickly. This should be the starter pack with every E3. Next I add a Raspberry Pi (I run one for each printer even though you can run multiple printers on a single one. I then do some buck boosters to run the power off the mains. I hate the stock PTFE tubes so I bought 6' of Capricorn anticipating that we'd be getting more printers.

That's about it really. A little more than some, a lot less than others.

Here's a dual gear version (single gear on your stock version) for $15 -->

​

I'm NOT recommending this particular extruder although I do have the single gear version of this on another printer of mine that works just fine.

I honestly would recommend you the dual gear extruder kit over the one that the other person suggested. It's a few bucks more expensive, but there is pretty much no slippage, and the extrusion is super precise. Here is a link (you can get it cheaper on aliexpress): https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF

Here is a great video about it by CHEP (great channel about 3D printing): https://youtu.be/QnrH2Sk7y40

this is a good one, https://www.amazon.com/gp/product/B07SY745CF/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1

make sure to change your E-steps to around 135-148. obviously your mileage may vary, but that's a good starting point. i like slightly under extruding, so i'm dialed in to 140 instead of the 148 that will extrude 100mm when a 100mm command is sent

Your best bet is to buy a metal extruder. Here is a geared one on Amazon for $15.

It would likely be better for flexible filaments, so an upgrade. Otherwise you might be able to wrap the threads of your MTC fitting with some teflon tape (plumbers tape), it may give your threads enough body to make up for the stripped threads but I wouldn't really count on it that much.

I use this one on my Ender 5 and it has been very reliable. It is geared and grips filament from both sides.

I'm quite disappointed as well. I had another post this weekend about the skipping and filament dust. In there /u/VolcanoOfUnicorns suggested this dual gear extruder instead. It's only $7 more than the metal extruder I bought (CHPOWER) but if it's designed better it seems like a much better metal extruder upgrade.

EDIT: Also thanks for letting me know yours also has this gap.

HAD THE EXACT SAME ISSUE, this was first solved by me raising the temperature, but it did still click. Do that and relevel the bed. If it still doesn't work get the ptfe tube put of the hotend and make sure there isn't any clogs or melted plastic oozing out blocking it's way. If still no luck, your extruder arm could be broken. You can check this by squeezing the arm during printing with just enough force that it still pushed the filament fine but its looser. This kinda solved it, but there are still other problems that could cause this:

1.Shitty quality control leads to improperly set potentiometers on the motherboard, so instead of the 0.9V volts it should be getting its set to 0.7V just like all the other axis.

1. Check if your power supply voltage is set currently. America is 110V, other places 220V

2. If the one listed above is set fine, it could be that, the voltage is too low in your neighbourhood just like mine, and thats a problem since the power supply divides the voltage instead of properly limiting to 0.9V

3. If still no luck, buy th https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF/ref=sr_1_1?crid=2T6FD8QGTKJD0&keywords=winsinn+dual+gear+extruder&qid=1579964263&sprefix=winsinn+dual+%2Caps%2C266&sr=8-1 , this solved almost all my problems since it provides around 1.5x as much torque.

Hope this was helpful!is

Might have mistyped. To clarify what I meant, as you tighten the screw, it compresses the spring which loosens the grip on the filament. Meant to say, less pressure on the filament.

Dual gear extruder

This extruder works very well. I found it via a video CHEP has on his channel. After installing you will need to change your steps/mm to around 140. You can follow the steps in this video. Dual gear extruder guide by CHEP

Aside from what other have stated regarding bed leveling and setting your z-level, get some Aquanet hairspray. Works wonder and its much cleaner than glue stick (spray every 2-3 prints).

Here are my highly recommended upgrades:

1. Get a new SD card, stock one tend to be buggy (Octopi is even better)
2. Bowden tube
3. Dual geared metal extruder (will need to print out a spacer for filament sensor, also need some m3x25mm to mount the spacer) - provides much better grip and extrusion than the stock plastic one; dont forget to calibrate extruder
4. UXCell 10mm OD 30mm light compression spring - longer than stock and helps to prevent the bed level knobs from coming loose
5. Gulf Coast Robotics all metal hotend - similar to MicroSwiss; better than stock. Factory heatbreak is fragile; mine started leaking after nozzle change

Happy printing!

The extruder on the direct drive mount is: https://www.amazon.com/WINSINN-Extruder-Creality-Upgraded-Aluminum/dp/B07SY745CF/ref=sxts_sxwds-bia-wc-p13n1_0?crid=WRMLHZWZZSIT

I swapped to a brand new nozzle a few successful prints before the problem started. I don't think the nozzle is clogged. And yes my extruder leaves bite marks in the filament normally. In this case the wheels are actually digging into the filament in a spot until they can spin in place. I've been using this extruder for almost a year now.

Is the extruder head in the link similar to the BMG. Is that a dual gear? Or should I get this one?

This one for the bed?

You can get them on amazon for cheap. I don't think they're by creality. They're much stiffer springs. What they do is push harder against the bed. This locks the adjustment wheels better. Since I have installed them I have had to level my bed like 4 times less often. I went from leveling my bed every other day to pretty much only once A week. It's a really good and cheap upgrade. You can often find them in packs with other upgrades too for a better deal. Here's some links.

These are the ones I bought.

I was thinking about getting that but I think I have decided that I'm going to skip that upgrade and go straight to a remote drive extruder. You keep your extruder in the same place. You attach a drive cable to it.the drive cable goes to a very small extruder above the hot end. It allows you to get a direct drive without much weight added to the nozzle. normal direct drives have the stepper motor right above the nozzle and that adds a ton of weight. This keeps the extruder off of the nozzle but still transmit power to a small direct drive. The drive cable turns a worm gear with turns the extruder. I believe it gives you a 10 to 1 ratio. So it literally makes it 10 times stronger, but it also makes it 10 times slower.there is a company that has a kit that you can attach to the extruder to speed the drive up. Or if you're handy with 3D modeling you could easily print a gear system to increase the speed.

the company allows you to buy the parts for the extruder either printed with an FDM machine or a SLS machine or a SLA machine. Or you could print the parts yourself. They offer a kit with just the parts you can't print. Then the files are free to download and print yourself.

This one stop selling due to the covid-19 outbreak. But I think there's is better because it weighs even less.I'm trying to wait and see how long until they start shipping products again
