- Chuck shows you a Fix for Under Extrusion on Creality Ender 3. He found it while testing a Cura 4.4 Plugin. He shows you the plugin and the problem he found on his Creality Ender 3 that was causing under extrusion. It was creating bad 3D prints that looked terrible. The solution is an easy fix and he shows you step by step how to fix it.
He also shows how the Cura 4.4 plugin works on the Creality Ender 3.

I love theses videos. I am a teacher with a seven year old giving me very little free time. The only reason I have been able to keep my ender printing is because of detailed videos like this that debug the process. Thank you.
I had exactly this problem with the extruder arm about three months ago, and fixed exactly the same way! Feels like a déja-vue 😀
You saved my ass! After 3 weeks of searching and troubleshooting I found your video. Sure enough my extruder arm was cracked. Thanks for this video!
I got my new printer and had been printing for 3 months and suddenly my prints went to crap. Just like the others commented, material wouldn't lay down and clumped up on the nozzle. I unclogged the nozzle, replaced the nozzle, replaced Bowden tube and fittings, bought a filament dryer...and I still couldn't even print a decent bed level test. I was so happy to find this solution.
This video saved me. My prints were coming out awful and I tried everything I could think of. Sure enough, I have the exact same crack in the exact same place.
I had the same problem a few days ago and didn't really knew what to do. So I ordered the dual drive extruder because I thought that this might fix it.
Really happy to know now that this probably fixes it, thank you!
Can't wait to receive it.
I really like your channel by the way! Glad I found it when I started with 3D printing.
Been dealing with sudden under extrusion and came across this video. Checked the extrusion mechanism and found that I have the issue with a crack. Glad I saw this. My under extrusion was minimal and random, trying to fix these issues is like chasing phantoms. I knew something had suddenly changed though. Thanks Chuck!
I just wanted to thank you for this video. For months I have been having an under extrusion problem and I couldn't figure it out. It turns out the idler wheel on my Ender 3 wasn't spinning during parts of the print. Luckily I had no cracks on my idler arm. So I just extended the spring out and put it back in and now it runs like a charm. Thank you so much!!!
I literally today started having this under extrusion problem. Went online. Watched this video. Fixed the problem (ordered metal extruder). Thanks Chuck Hellebuyck (hell-eh-buck)! YOU ARE THE GOD OF ALL 3D PRINTERS!
Thank God. This video made me take a closer look at my extruder AND nozzle, didn't have the same crack but the filament I'm using almost sawed it's way through the arm. They should probably advertise more clearly that glow in the dark filament is abrasive! Thank you so much!
after hours of leveling and cleaning i found this video and that was my issue!! THANKS
I’ve tried all the other under extrusion fixes and almost waisted an entire role of filament trying to fix it. I never would have seen the small crack if it weren’t for this video! Thanks so much!
I seriously cannot thank you enough for this. After months of trying endless fixes I found across the internet, this is the one that did it.
Same
Thanks for spreading the word on the extruder arm crack. It is a very common issues it seems. It is inevitable that they break on ender 3's within the first 100 hrs of printing.
Happened to me last week. I went with the dual-gear extruder. That works great.
Thank you! I COULD not figure out why my prints were spotty, barely laying down any filament, then laying down none at all mid print. It didn't help that the lever arm broke simultaneously with switching to a new, budget filament. Never was so happy to find a piece on my machine broken because I now know the source of the problem I've been trying to troubleshoot for a few days now.
Always coming to the rescue. I'm glad I already ordered the mentioned hardware before even knowing that spinny was broken.
Yes, I would definitely like to see the time remaining on the print screen. I am having gear slippage, not sure why, but I have a dual gear extruder on order. By the way, thanks for all your videos. Yours is my goto channel when I have printer problems.
I have had extrusion problems for over a year, tried everything from cold pulls, replacing the extruder head, raising the temp and lowering print speed and this solved everything. Thanks!
Same exact problem on my Ender 3. Chased this problem for days before I found this video. Thanks CHEP!!!
Yup. Been printing for a month and just now starting having trouble. After trouble shooting different issues all day, this was the problem. The grand canyon was forming under my lever arm. Thanks Chuck! You're always my go to with these issues.
Cheers Chep, I had upgraded my Ender 3 to the metal extruder drive shown in your video over 6 months ago and whilst initially things were great just lately I've had some issues with blockages and under extrusion creep in... the mention of checking extruder stepper mount screws made me check mine... all 4 were loose.
I had the very same problem only a few weeks after getting the Ender 3 Pro. I spent a few days trying to find out what was going on until I finally found the crack. I wish it had happened to Chep before me, since this video explains everything really really well, as always. Thank you Chuck for your excellent videos, they are very helpful and fantastic quality. Keep up the good work!! :)
I have to really thank you. I bought my Ender 3 V2 2 weeks ago and had severe underextrusion from the beginning.The crack was the problem! I replaced it with an aluminium arm and everything works smooth now. Thank you for saving me more painful hours of debugging.
I was having trouble with under extrusion and couldn't figure out what was going on until I came across your video. Thank you so much, I just wish I would have found it sooner. I used your affiliate link to purchase the metal extruder. All the best!
Dude, I love you. I was having a similiar problem of under extrusion and had no idea what it was. Then I saw your video, and bingo: it was a cracked extruder. Thank you!
Hi Chuck, My ender 3 stock extruder had exactly the same symptoms that you describe. I found the idle wheel crack almost in the same spot as you show in your video. After replacing the stock plastic extruder with the metal one, all problems went away. Thanks for your detailed and accurate description.
Cool info about the plugin. Always wondered why Cura does not add this by default. As always great and informative video. Keep up the good work.
this tip really saved by day. My pully gear was not moving which was causing inconsistent extrusion. After adjusting so the teeth gear and bearing the problem was resolved.
I DID THIS AND IT CREATED A NEW PROBLEM, I got my ender 3 about 3 months ago, and this extruder was a cheap upgrade that seemed worth it so i went for it. THEN i started printing Overture Clear PETG and I kept getting clogs about 1/3 into the print. They weren't clogging at the same spot exactly but close.
I already upgraded to the Capricorn Tubing as well. Every time i would get a clog it was hard to pull the filament back through the tube. I noticed the extruder teeth were deeply embedded into the PETG so i took some quick measurements. Oh WOW- the extruder was smashing the PETG so hard that it was expanding vertically from 1.75+- to 2.10mm. That is a real problem since the Capricorn tubing is ID: 1.95mm ± 0.05mm. AND to add to the problem the location of the extruder puts the marks on the outside radius of the PETG as it travels through the tubing causing increased friction as it pushes against the outside of the tubing.
MY FIX- When i first assembled the new extruder i had two tension springs in my hand(new/old), i chose the stiffer spring (using the accurate forefinger/thumb squish test) thinking the extra tension would be a benefit. ( I was wrong) - NOW I put the soft spring in and haven't had a problem in 2 prints. I hope this helps. Keep those first layers squished! Good luck!
I can't thank you enough, I've been having this problem for awhile all my prints had became brittle.. Changed the flow everything then I look at that turning nob it was stopping so I have the same extra part as you and changed it! Dude you fixed it! Thank you!!
My man, I've been having such a headache the last few days, searched up causes, found your vid and dammit broken arm...take my like and favorite.
two weeks of trying to reproduce my underextrusion behaviour with absolutely no consistent pattern and the fix is three minutes of screwing and ten bucks.
You're a hero chep :) I salute you!
Yes, my extruderarm broke to after about 6month of moderate use. Iprinted a replacement from thingsreverse but have now ordered a E3D Hermes.... ;-) Thanks for this great channel, I've learned alot!!!
I'm happy that you covered this issue, however this is something that was enough of an issue A YEAR AGO that I bought two Ender 3's (non pro) and replaced the extruder tops with metal units immediately. I did order the dual gear CR10S pro extruder tops for both, but I haven't had the need to install them yet. I enjoy your videos, keep on doing what you're doing.
Wow Chuck I just wanted to thank you... after posting on the Creality Ender -3 3d printer user group and getting MANY suggestions I came across this video and YES I had the broken filament feeder arm.... so now after upgrading the arm and the filament tube to the Capricorne tubing....1 quick leveling and BINGS back in business.
Thanks again so much
You’re welcome.
Hello Chep, I am a subscriber from France, and I am frankly delighted with your youtube channel as well as the content of the videos and explanations provided.
and delighted to have the opportunity to see the time remaining on the 3D prints.
Thumbs up for you Chep, because this fixed my sidewinder X1. Thanks!
WOW! Thanks Chep! I had the EXACT same problem. Pulled off the lever arm and sure enough, there was a crack. You saved me many hours of trouble shooting!
I had been suffering from under extrusion for a while but it was intermittent. I tested esteps, flow rate and everything I could think of.
I had already replaced the extruder for an all metal one a long time ago but something clicked when you mentioned the idler wheel not moving, I went to check it and the bolt had come loose and was indeed not turning.
Be sure to maintain your bolts people, it can save days of frustration!
had the same problem tried everything cleaned nozzle, changed nozzle, changed bowden, tightened the spring of clip arm without knowing there was a crack which worsened the crack but finally found this video and tada i found the problem nice work man could not have done this without you
I had the exact same problem. You saved me a ton of headaches! Thank you!
Had to log in just to let you know that the cracked extruder was my issue as well. Thank you for this video, you helped me solve my under extrusion issue!
Thanks for pointing me in the right location as I have just had the same fault. Great helpful guy. I am now using cura and your advise is invaluable. Thanks
After like 2 weeks of having issues I remembered your video. I didn't have a crack that I could see, but when I put pressure on the extruder arm like you did my problem went away leading me to conclude that my extruder was the issue. I have ordered your linked extruder and will be installing it today. you are a lifesaver!
you can use a yellow bed spring on this extruder to
Thanks Chuck, you really helped me a lot with this video. After six months my Ender 3 would under extrude random layers in the middle of the print, which was initially annoying and made some ( but not all ) of my prints weak. Gradually the problem got worse, to the point where I was almost getting results as bad as you were getting here. Once I watched this video I was sure that I must have a similar problem. I removed the stock plastic extruder arm and sure enough it was split underneath, right next to the threaded insert. I purchased and fitted an aluminium replacement extruder and my Ender 3 is printing perfectly once more.
I cannot stress enough to anybody who buys an Ender 3 that you should just order the aluminium extruder at the same time. Replace the stock extruder as you build your Ender 3. It's a cheap upgrade and it's one which eliminates all kinds of problems in the future. I've had to bin quite a few prints and when the problem was only occurring sporadically it was super frustrating because I never knew whether my print was going to come out strong or with one or several under extruded layers. The aluminium extruder is definitely the way to go.
Love your channel Chuck, appreciate your efforts and am a subscriber !
Thank you for sharing the cracked extruder arm tip. I have been fighting intermittent under extrusion for a while now and it was driving me crazy. my extruder arm was also cracked. thanks!
I saw so many posts/comments/videos about the broken arms that I printed a replacement one way before mine broke... But, eventually it broke (and I had a replacement already waiting). More recently I also changed to a full metal set and OH BOY it is so much better. That should be the standard.
Thanks! I had the exact problem, my prints were horrible and sure enough, the plastic was cracked and the pully wasn't gripping the filament. My replacement will take a week, so in the meantime - I used my wood burner gun, clamped and melted the plastic pieces together and even added some melted filament for good measure. I know it will fail soon, but I was able to get 2 perfect prints so far until the new parts show up. I also didn't tighten down the pully screw, just enough to hold it in. Pully spins freely and crack is filled. Waiting on new part, but my prints were looking terrible! Tried everything you did to no avail until I saw the crack. Excellent video!
Excellent-Thank you! Didn't think to look there....I can see the bearing isn't rotating as it should....I found that I had the bolt a little too tight not allowing the arm to swing back correctly...loosened it off a bit and it works fine....upgrading to metal.
Another detailed video that's straight forward!! I've been with my Ender-3 for almost six months and still have the stock extruder. I'm using the same cheap metal extruder on another printer and gets the job done!! I guess it's hit or miss with Creality's quality!!
Had the same problem in the past. The arm was also cracked. A cheap all-metal extruder from AliExpress fixed it. Thank you for spreading knowledge :)
Thanks so much, couldn't get my Ender 3 to feed, after watching your vid checked for cracks, and there it was. New metal one is on order from Bangood.
Saving your video for future reference. Looking into upgrading to the metal extruder perhaps next month.
I recently just started having this problem I have had my printer for about a month now and have had great results with everything stock but in the last few weeks I started to see extruder marks in my models and layer lines ext... and just a few days ago under extruding and horrible looking models so I came across this video so I started troubleshooting I started with my hot end and nozzle no blockages I re-leveled my bed made sure my Z offset was correct ran my bed level I have a BL Touch installed nothing worked so I just checked my extruder and found the extruder arm craked under the bearing so I have an order in for a metal extruder will be here tomorrow thank you CHEP for the great videos I have learned a lot from this channel and really enjoy the videos
After printing for 8 months having a few issues together at the same time, all of a sudden there were bands of underextrusion in my layers. After a considerable time checking this and checking that, I looked at this video. "Bob's your uncle" the extruder arm pivot screw is too tight. My problems fixed! Thanks Chuck!
Did the time remaining thing, love it! Thanks Chuck, AGAIN!!
Great advice!! Exactly what was going on! I can't get the dual traction because my stepper does not have a removable wheel, but I just ordered the regular one. Thank you!!
Holy crap, I didn't even think about the extruder tension arm. I had replaced and cleaned out and verified every bit past the extruder and have beating my head against the wall trying to figure this out. Turns out my tension arm's crack was super close to matching yours exactly.I had a winsinn upgrade kit handy that I hadn't put on yet, but unfortunately the spindle and gear on my extruder motor are not the same as yours so I wasn't able to apply either of your fixes (the tension arm [my kit is slightly different than yours], or the replacement) as I have the compression fit gear. However, new motors on the way (thanks amazon) so I can get this printer fixed, and go ahead and upgrade my other Ender3 as well. As usual some sage advice. Thank you so incredibly much.
I've been struggling with problem and finally managed to resolve it last week. I replaces it with the dual gear version. getting great prims now.
As usual, great video, Chuck! I have the SeeMe CNC EZR Struders on my Ender 3 and CR-10 Mini and love them.
i did have the identical crack! CHEP youre the man thank you for all you do brother!!!
Thanks, I had this extrusion problem and I was really scratching my head, My filament guide was cracker exactly like yours.
Thank you so much, man! I had so many problems with my Ender 3, where the walls were not sticking together, but layer adhesion was good. This would make it so I could peel off the walls. I looked at the idler, and I also observed that it wasn't spinning at the same rate as the gear. Turns out it was the spring. I had already upgraded to a full-metal extruder but maybe didn't replace the spring. I still had the spring from the kit, and when I put it in, it worked like a charm.
You're a life saver I would never have even considered this
You are a life saver. I had been fighting with mine for a long ass time. My problem originally was heat creep but replacing the hot end only half fixed it. This was the other half. I have the arm rigged with a rubber band until that kit arrives. I bought another for my cr 10 so that it doesn't happen on that one.
once you start modifying your 3d printer it becomes your daily routine and you cant stop. I got myself an ender 3 pro i made the "th3d" upgrade and ever since i havent touched. i had a prusa clone before and it died in my hands while i was trying to make it better. i learnt a lot but well. i like chep for his handy solutions using software and on the machine itself.
I'm calling this video gold. I've had bad prints/under extruding for a week+. I've tried a lot of different things. This makes sense. I'll find out soon. I ordered the replacement. I'll post what I learn. Hopefully, good.
THANK YOU! Been trying everything to fix my under extrusion. Checked my arm and it is like you took a picture of my arm and used it in your video. Then new metal one is now on its way from Amazon. Perfect timing on the video Chep!
Glad it helped.
I cannot thank you enough for making this video. Sure enough, my issue ended up being the cracked arm. Thank you!!!!
This video saved me butt! For an entire week my prints have been brittle and awful. Sure enough, the arm was cracked underneath. I replaced the extruder with the aluminum one and after recalibration, I’m back in business! Thank you!
Yes, this is exactly what happened to my ender 3 arm. I spent a whole day to find whats wrong with it. Changed the tube, nozzle, couplings a several time until I noticed that the gears of extruder does not spin well. And the arm is cracked, I replaced it with full 3d printed in carbon 30 % fillament, 100 % infill, and it worked perfectly. Too bad that this video was not released before this happened to me. I am a big fan of you work and keep up the good work!
Chuck - thanks for your videos. They are great help. On the metal extruder I bought recently, they include a rivnut to go on the bolt through the spring. It’s a smaller size than the bolt, so the bolt does not screw in (M3 vs M4 I think) but this stabilises the spring and also allows you to tension the spring with the bolt, because the metal frame is also threaded (The rivnut pushed against the spring)
I want to say thank you very much! I never would have picked up that cracked arm! I tried everything before finding your video. Sure enough, I took the arm off and there was the crack. In my case, I glued it back together (just to make sure this was in fact the issue) and it fixed the under extrusion. I did however purchase the aluminum fix. Thanks again!
Hehhe. I actually removed mine to check if the gear next to it isnt maybe dirty from filament and slipping. When the arm was off and i turned it around... ta daa
You saved me! I was getting crazy under extrusion the same day I had successful prints without any setting changes. My extruder was cracked and never would have guessed to check the tension as it appeared the wheel was moving with the filament. Thank you!
Glad I could help.
OH MY FREAKING GOSH kind of upset that I didn't stumble across your video sooner, been struggling on and off to solve this under extrusion problem for like the past week. Thank you!
edit: definitely subscribed now thx again
Thank you CHEP! just ordered a new extruder
Thank you very much for this video! I'm having the exact same problem and wondered why nothing else helped.
Super helpful! I’m pretty new to 3D printing and the under extrusion was driving me crazy! Sure enough, I had a hairline crack just like yours. Thank you so much!
Well i hadn’t printed anything out it quite a long time and when i started my ender 3 v2 back up i had terrible under extrusion… watched you video and sure enough there was a big crack! Thanks!
Thank you so much for your videos Chuck, i always find a useful solution in this channel
My arm went from being totally fine to completely sheering off. Waiting on the new one today so I can get back to printing again. Thanks for the video. 😁
Thank you CHEP! That's EXACTLY what happened to me. Been battling under extrusion for weeks now. Watched this video and disassembled the lever arm and there it is....the lever arm was cracked underneath. Should have watched this video 3 weeks ago. :)
just found the same arm breaking problem here. thanks for the heads up
Next cookout....I'm inviting CHUCK HELLA-BUCK!
Thank you so much Chep... I will remember this when my ender 3 pro start printing weird... I it will be a good starting point to know what is going on
This is the first thing I do to any of my Creality printers now. First had the problem with a NIB CR-10s. Never an issue after replacement
This video helped me so much. I din't have a crack or anything, but the guiding wheel had to be tensioned.
DUDE! I watched this, went over to check my unit and what do you know, a huge crack in the extruder arm!!! Kit ordered. Thanks!
Great content, as always. But one part I wanted to touch on was the bit where you said the gears were the same diameter so you shouldn't have to adjust your esteps. If you adjust the extruder, like many people wind up doing for more tension, you should recheck your esteps for sure since it will likely change how much filament gets extruded. This is especially true for those who changed their esteps while under-extruding.
Thanks man. I had the same crack. Just ordered my new extruder
Found problems with the extruder, thought it was the spring getting weak. Your video let me find the massiv crack in the arm instead - many thanks!
Thanks for this video. I was having a major problem with under extrusion and I thought it was in the hot end so replaced the nozzle and did the hot end fix and nothing changed. I watched your video and had a look at the extruder arm and didn't see anything but did notice the guide wheel was hardly moving. There wasn't enough spring tension so going to try a new spring...I think I have a few...lol
Really enjoy your great videos Chuck. Been watching your channel since purchasing an Ender 3 last June, along with a couple of other channels that seem very knowledgeable of the Ender 3. Finally decided to assemble it last month, after deciding on what upgrades I would do during the assembly process. It worked great - hot-end & bed heat up accurately; X. Y, & Z axes all move smoothly, quietly, and accurately. The only problem I have is the extruder (motor). It does not work. Am able to turn the motor shaft by hand and all the connections seem to be OK in the electronics case. I am stumped. Any suggestions / thoughts? -- Patrick
Thank you so much. This video saved me so much time and headache. My printer is working properly again!
Same extrusion problem, identical crack in the plastic arm. Thanks!
WOW! thanks a lot...mine too...I'm glad I had the upgrade on-hand. Easy fix!
Yes, I found a cracked arm a while back. Great videos.
Thank you, I had a cracked arm as well. Driving me crazy for weeks
Thanks again CHEP. My printer was doing the same thing, and finally decided to replace the extruder. It was also the hairline fracture. Just bought the metal replacement.
Would be cool if the Ender came out with an expensive part model (such as metal extruder/better PTFE tubing/higher quality springs) would defs be worth buying
About 2 months of printing now and haven't really had any troubles. Started getting extreme under extrusion and tried everything. Been at it for a couple hours now and was just about to give up because I haven't been able to print. Found your video and checked notice that my lever arm is cracked! I couldn't believe it! Thank you so much for preventing me from losing all hope!
Having the same issue atm. Were you able to fix it?
@@vodfives5555 yup! Replaced the extruder because it had a crack in it that was hard to see. Once I unbolted it, it basically fell apart into 2 pieces. Bought a metal one and haven't looked back since!
@@StenBuilt that’s great! My metal one will arrive today. I couldn’t believe that this was the issue because my printer is only like a month old and I haven’t changed filament a lot so I didn’t push the lever a lot
@@vodfives5555 I don't believe I changed filament too often before mine broke either, but sure enough, the lever arm was barely being held on. Once the bolt for the arm came out, it almost fell apart. The crack was hard to see until I shined a flashlight directly at it when it was all still assembled. Glad to hear the metal one is arriving today so you can get back to it!
@@StenBuilt I really don’t understand why creality still ships the printers with the plastic extruder then. Because mine was definitely broken for a while because I noticed I had small under extrusions in all my prints before it completely failed 2 days ago
I bought my printer a few weeks ago. So far I have no issues with it, but thanks for the video. Now if this problem comes up I know exactly what to check
