Hi guys,
We have seen very frequently users showing carriages from their 3D printers with lots of play and ask for help on how to fix it.
In this video, we will explain in detail what are eccentric nuts, how you can fix the wobbling, and how to correctly adjust the wheels of your carriages.
This procedure works for any type of printer that uses carriages equipped with wheels and eccentric nuts.
Check the video for all the details : )

3 years old, this video still saves printers from being thrown out the window. Thank you!!
Thanks Peter. Glad it helped :)
yep, easy fix. thanks heaps
I am also named Peter and this video helped me to not thrash my printer, so thanks.@@ruiraptor
i was almost losing my mind.Then i found this video.Thank you.
Me too!! Lol
Me too! My wheels startet to do weird noises. Then I found the video. I tightened them too much, cause i didn't know these are eccentric nuts :D Thx !
I hope you properly tightened your mind back in once you saw this video!
I bought an Ender clone LotMaxx printer last year, and recently the Y axis got way out of acceptable looseness. I kept reading in a few places about "eccentric nuts" but didn't know what that was all about, now I do, thanks to this video: I'm hoping the cheap printers I got have these!
Loosing or losing?
Same
this is the most important video out rn for the newbie 3d printing community
Thanks for the feedback. Glad it helped :)
2:40 This is the information I needed. I kept turning and turning. There’s no need, just a 1/4-1/2 turn needed. Thanks.
Same here, I was wondering why when I turned the nut the carriage would tighten and if I turn some more it would go loose again...That image of the center of the nut at 2:00 explained SO much.
omg this man just explained something in like 1 minute where i was looking for for over a week
Thanks. Glad it helped :)
Just how a tutorial should be! Brief yet explains a lot
My man, the eccentric nut advice absolutely saved me so much trouble. Saved me from having to order a new part- thinking that my x carriage was ruined and needed replacement- and waiting for it to arrive. Thank you!!!
Thank you! I know it may seem simple, but I was gifted a 3D printer and have never used one before. Also never used anything with eccentric nuts for adjustment, so this was a great tutorial for me.
Thanks you saved me hours/days of troubleshooting with this simple fix
Thank you very much. I worked on Radars and repaired all kinds of electronics and I was going insane trying to figure out how to adjust the Eccentric Nut. I have never, in my 38 years of working in Component Level Repair on all kinds of electronics, and I worked on electronics all the way from Tube circuitry to Digital and I have never seen an Eccentric Nut. When I saw you video I went and looked up the definition of the nut and sure enough, the center is offset. Thank you for giving this newbie back his sanity!!!!
Fixed my issue where other videos failed, thanks for the detailed explanation!!!
Thank You for helping me with this. Mine was wobbly and didn't know how to fix it until now. You are a Godsend!
Perfect explanation with out all the fluff... I thought I was the only eccentric nut!
Holy crap. I just found this video after a reddit thread made me aware this was a thing. Tutorial is great and I'm amazed at just how big a difference this can make on an otherwise well tuned machine.
Thanks. Glad it helped 😊
Wow, great explanation. I keep seeing guides mentioning to adjust eccentric nuts. This video explained how that actually helps and how to do it properly. Thank you so much
These are amazing quality. I love the 3d model breakdown/examples.
Man, I was panicking because I spent 40 mins and was like…how did I tighten it when I first got it??? It’s like I lost all knowledge. Thank you for saving my sanity. Appreciate it!
Thank you so much. My boys got a printer for Christmas and were so frustrated that their carriage was wobbly. Your video let dad come to the rescue.
You are truly an angel sent from the heavens, I really appreciate how in depth the video is. Really makes things clear for a beginner like me. Thank you!
Fantastic video. I got stuck on this part while assembling a 3d Ender v2. How easy it was to figure out, with your 3d models. Thanks so much for the effort to put this video together.
Thank you for a very thorough and detailed video on a very specific area (eccentric nuts). I feel a lot of other videos out there do a lot of unnecessary chatty talk which I get. But your video is focused, detailed on the tiny aspects. I really like how you explain every angle of an issue such as: Do xyz like this and this is what should happen, if you do too much abc will happen, if you do too little then 123 will happen.... again, thanks for a no BS, short and simple, thorough HOW TO video. Subscribed!
Hi Malcolm, thank you so much for you comment.
Dude you are the only one on TH-cam who can explain this problem. Thanks so so much!!🎉
I was very disappointed with my new 3D printer bed. This video fix all my issues with the printer bed. thank you so much. ,🤩🤩🤩👍🏻👍🏻👍🏻👍🏻
Brilliant, thankyou. I never thought I would have a an problem with an eccentric nut......All the best
Hi, thanks, glad it helped 🙂
thanks I didn't know how those nuts worked - loved that this video was short and to the pt.
Excellent video. I wasn’t sure how the eccentric nuts worked, so this answered my question.
You make excellent, easy understanding, and informative videos. Many thanks
Was upgrading my duct with a printed one and i lost my mind trying to fix this, thank you very much
I just ran into this last night with my Ender 3 V2. This short video was perfect.
You're amazing. My travel Ender 2 was super wobbly after I unpacked it from my suitcase, and I thought I messed something up. I tried loosening all of them and pushing them towards the center while I tightened them, in case the holes were wallowed out, and that did nothing. I'll have to adjust everything the right way once this print is done.
Hi, thanks, glad it helped 🙂
This video saved my sanity. I just got a new S1 and before putting it together, I noticed the X travel would find a "bump" in the middle and near both ends. I was very dismayed at the thought that I had received a lemon. After adjusting the carriage wheels, the bumps went away. I am a happy Creality customer! Thank you so much for this video! I subscribed.
Thanks for the feedback ;)
Thank you for helping me find the eccentric nut on my hot end trolley. It was really loose and super easy & quick to tighten it up with the skinny wrenches provided with my LK5 PRO.
A million thanks, I was freaking out. It's my first printer.😊
Glad it helped 😉
Thank you! this solved one of my wobbly problems. So glad I stumbled upon this video, I was able to adjust the printer head.
2 weeks of trying to fix one and I finally found your channel yesterday. Thank Man, saved me from throwing mine under a truck......
Great video. No music. Good camera work and well narrated. Thanks.
Thank you so much! I’ve had my printer for almost a year now and thought that it was just supposed to be like that :D
Great job explaining with detail about how this actually works.
thanks for the vid! my gantry on my ender 3v2 had like a obscured amount of play on it.
Thanks for keeping it short and simple!
Thank you for the tutorial, I'm happy to see that there's a video on something this important especially for an ender 3 I'm sure most people don't pay attention to slack on the z axis if its not tightened right its actually slanted and mine was till I learned about them, one thing that's super important to note is if you don't have them tightened right it can look like under extrusion instead! one thing Id love to see is a video on how to geese the wheel bearings because their is only one vid I've ever found and its not all that great so id honestly like to see something on how to properly grease them!
You are my hero! I knew what my problem was, I just didn't know how to fix it! Thank you so much for making this video! You saved me from pulling out my hair!
wow so simple for something that I thought was going to be a huge headache
You should be able to turn the wheels with two fingers with just slight resistance. As stated, the best and most reliable indicator of being too tight is when running it back and forth, you feel some slight bumps along the way and of course if hard to move it's WAY too tight. The ideal should be traveling pretty much glassy smooth, but no wobbling either.
Also, before getting to this point, when first assembling the upper carriage framework, you should check it all for being square and that, on a level surface, the feet all make contact and no rocking. To fix the latter, you can loosen the frame members and let it settle all to be flat on the table with all 4 feet, then re-tighten. As for any frame issues not being square, you can often just loosen, move them a bit and snug them back and find they will fall to be square. If not, worst case, you could put some thin shim material on one side, like some layers of aluminum foil until when you tighten the framework it all ends up square.
The squarer and truer you can assemble your printer the easier it will level and make great prints.
Lastly, when leveling your bed too many times the knobs will be too loose. If too loose, the bed can easily get out of level from bumping or even just removing a print that is stuck a bit. You want these to be pretty snug and to get them there when assembling, you may have to loosen the bolts on the Z stop and slide it down minutely and tighten so that it will let the head down lower for the more greatly snugged up bed leveling wheels. Try to target the springs for the bed being about 50% compressed and you should be in great shape.
I buy a lot of "unrepair" printers on Ebay and if you get confident in doing all these things as well as troubleshooting printers, you can save huge buy buying these customer returned printers.
Today I fixed a Lottmax Shark V2, bought for $95 shipped as they occasionally pop up on Ebay, a great deal, and just had to bend some extruder mount metal brackets to get things squared up and it's working great.
Thank you I needed this will try in the morning got my nephew a 3d printer for Christmas and I want it fully set up but was having issues with other videos and finding the “eccentric nut” now I know what to look for
Just disassembled then reassembled the print head. Couldn’t understand why it was wobbling. Spent hours looking for the part I’d “obviously mislaid!!” . Then watched your video - problem solved in minutes. Thank you.
I was trying everything putting duct tape on the wheels and tightening every nut possible on the head. This solved my problem thank you.
I had no idea there were eccentric nuts lolol. Glad I came to TH-cam for my answer! Thank you!
Glad it helped ;)
Just the answers I needed!! Thanks for putting this out
Thank you ruiraptor, thought it was something terminal. What an easy fix and great tutorial!
Just a tip, where there are 2 eccentric nuts I find it very useful to mark one edge of each nut so that you can ensure that they are parallel
Hi Brett, your tip is very good. The best is to do exactly that on all eccentric nuts while assembling them (for the cases where the parts come disassembled).
Echoing others, short, to the point. Thanks for the video.
Thanks for the feedback.
2:44 - Great explanation and demonstration. Was confused how exactly this should be properly tighten. Thanks. Can you make a detailed long video or series on how to professionally assemble and square 3D printers or CNCs using good calipers, test indicators, different types of squares and granite surface plate?
Thank you very much for your explaination. It's much more better than what you can find in the manual or the manufacturer's video. Actually it's the best illustrated video about this subject. (sidewinder x2 here)
Hi, thanks for your kind comment. Glad it helped 🙂
I've been trying to do this for 30 minutes and did get why it doesnt tighten and your 4 minutes video solved it!! Thanks alot.
Glad it helped ;)
Thank you very much, always wondered how these work
This was so Helpful, Thank You
super helpful and so clear to understand thank you!
You explained it like a pro!
Cheers m8
👊
Super helpful 👌 Short and informative, respect m8 🤝
This was very helpful, thank you!
This is a great video and very well presented. I do not have a 3D printer but a laser engraved and cutter with the same issue. Thank you for sharing.
I did this on my CR6 Max both the bed and the nozzle- now running a ABL Hopefully It Fixed my scraping sound ( it was making a weird sound every time the bed moved in a fast motion) the bed rollers were only tight on one side and worn out only on one side. Thank you so much you probably saved me.
Thank you for this video. Was going crazy trying to figure that out
This is what all tutorials should be
Thanks 🙂
Wow. Great tutorial for a newbie. I didn't understand, until this video, when eccentric meant. Just knowing what eccentric means is half the battle.
Thank you for your feedback Brian 🙂
Really good clear explanation, thank you.
I found this super helpful!! Cheers!
Perfectly explained, thank you Sir 👍
thanks a lot ! i always had issues with the bed levelling and didn't knew how to delete the wobble ( and i didn't even knew that such screws existed)
thanks, this helped me out a ton, had no idea how to fix my wobble!
Excelente trabalho Rui👍
Got really pissed, found your video, got really happy.
thanks
great video. straight to the point, no bullshit and yet a complete explanation
Thanks so much for the breakdown! It never made sense to me why tightening or loosening the nut seemed to have a snag. Seeing that its because of the off center hole makes it much easier to get perfect.
Thanks so much! I was at my wit’s end trying to figure out what was wrong.
Thank you. Saved me a heap of trouble.
1º video que me cruzei dos teus, e explicou muito bem o problema quando eu já não me recordava como fazer isto. Ganhaste um subscritor! Cumprimentos
Obrigado Victor 🙂
Great tutorial! Much appreciated!
quick and easy fix for the hotend wobble on my ender 3 v2. prints werent affected to the point of misprinting, but one of the wheels wasnt spinning correctly and it was annoying me. this video fixed that
Worked perfectly. Thanks
Perfectly worked for me... Thank you...
Hey thanks for the video. Very clear on what to do even if my Spanish is a bit rusty, the captions and video filled in the blanks. Gracias!
Thanks for the explanation ! Now it makes sense to me
This helpful. So helpful I forgot about it, watched it again. And found previous me liked the video already. So helpful...not my memory helpful but helpful
Thanks for a very well explained video.
Thank you this video was very helpful 👍
Thank you for this video 🙏. I thought I just dropped $220 for this to happen but now I have it fixed up!
Very helpful! Thank you!
Thanks man! This was driving me crazy, I was like, I swear this wasn't lose before 🤔
Thanks so much! I am having the *bump* issue, and didn't realize it may be due to over-tightening. I will try your recommended fix!
Glad it helped :)
Thank you for the tutorial it was fantastic video, it was SO SO helpful!!
Perfect I love this I got a ender 3 for Christmas and I had the same issue I looked up countless pages but this was a all in one explanation
Thank you for the feedback. Glad it helped :)
It really fixed my problem :D thank you and greatings from Chile!
Thanks 🙂
I was just about to give up on my Ender for another week or so, thank you!
Just what I needed! Thank you!
Glad it helped 🙂
Best tutorial ever seen
Thank you for this! Kudos!
This is so basic, why am i so stupid. Had to recheck mine later, after i installed Hero Me mods my rails wobbling like crazy.
Thanks mate, you save my day
Saved my printer from the scrap yard thank you!
Thank you very much for the tutorial. You made my day 😊
Thanks, glad it helped 🙂
