Thanks! Absolutely - printers got so much better recently, but even so: from time to time you get at least very puzzling models that refuse to print the way you hoped. I enjoy the mastery of the hobby (when you are not running against the clock). Happy holidays for you and your loved ones 🎄❤️

"Bordering on the realm of superstition" is soooo true about this hobby. 😂

​@@4thfrom7I was going to say the exact same. 👌 They nailed it with that description. I then proceeded with my ritualistic chanting around my Z axis in prayer as i begin my next print 😅😅 (I think I should see someone about this habit LOL)

Remember to recite your daily canticles.

All hail the omnissiah

Yeah, I’ve been following his drama and it scares the B-Jesus out of me! I hope it helps a bit 👍🍀

It was not in-transparent. It was because he had discussed printing firearms on his channel.

@@johnbeima6413 That's not against the rules. Major channels like Vox have also shown 3D printed guns.

@@SianaGearz Actually it is. :) Read the new terms. He even mentioned he had been warned about it before.

he had already previously deleted his firearm related videos months ago to hedge his bets and make sure, and tried unsuccessfully to communicate with youtube directly to ensure he was in compliance. none of that mattered and they still banned him without cause. i dont know why youre so invested in caping for a huge tech company without even getting paid for it@@johnbeima6413

Oh, you got yourself in a delicious tortuous path of maddening learning 🤣❤️ Enjoy, my friend. Highly addictive for tinkerers.

Oh, thank you! I am happy you enjoyed the storytelling of the process! I had to reenact some of it - the only thing I had REALLY recorded well at the time was the parts that were getting out of the printer, and not much more.

My big brother is a Great teacher!!! Teaching using questions and making everyone start thinking with him! Perfect storytelling!!!

🤭 Bro… you are selling me too well 😂

Wow! I loved your advice: hard to beat the experience of running a Big printing farm 👍 Do you have a favorite way of cleaning the Rods?

@@GeekDetour hot water, Dawn detergent, and a bristle brush. Dry the rod (and brass guide) completely with a super absorbent car-wash microfiber towel that leaves no lint behind and then LIGHTLY spray one THIN coat of Corrosion X Lubricant. She'll glide smooth and need little maintenance after that.

Oh, you really take the rods off and treat them good! I only did that twice in one printer. I want to try POM nuts, it seems they should run dry.

@@GeekDetour never tried the POM nuts, but if they work, they work. Now I'm curious about them again. I may order a set. Sigh, the tinkering never ends 😅

Did this solve the problem?

That’s so nice to know! Thanks for sharing it with me ❤️Merry Christmas 🎄

omffffffffffffffg thx so much...im an expert, but am the biggest newbie at the same time, seing this.

You have no idea how much I loved reading your comment! Thanks! Very often, when I am working on a video, I overthink things… and imagine: “geeez, isn’t this super boring, or trivial?!” 🤣 Crazy how adding parts, even when they are designed to improve, can actually make it worse. I am happy for you!

I am glad you liked Sean’s book - I bought mine in July last year and I really thought it deserved more exposure. But I had to wait for the right video to show it. 🤗

Hi again. I finally got a print I'm happy with and just need to sort out some minor Z-binding. I was wondering if there is a specific type and / or brand of lubricant you recommend? I am fairly certain all that is happening is minor Z-binding but until I grease the rods I won't really know lol.@@GeekDetour

Thank you so much! ❤️🎄🎊🎉

Adrian! Thanks man! ❤️ Merry Christmas for you and Mihai 🎄🎁

Oh, thanks! That’s true! And you know what? For a lot of people, the most satisfied machines are the ones you can actually mess with, add stuff, change parts… It is cool to have a machine that does great and you just hit print… but I wouldn’t be happy without having at least one machine that is always open in a constant state of change.

Oh yeah! The A-ha moment after a maddening chase… LOVE IT! Thanks for sharing!

Hey, I’m having the same issue with my Kobra Plus that has a volcano. When you say standard volcano nozzles are you meaning like the genuine e3d nozzles fixed the problem or something else? Thanks!

I am having this exact same problem, could i add you in discord or literally anything so I can send you pics and you can potentially confirm its the issues? New to FDM and have Kobra 2, everything was going fine but now I'm getting very frustrated.

Glad you enjoyed it! Yeah, in the end, it is like a tiny factory.

Yeah, you are absolutely true: each Z-Lead Screws has an imperfection signature. We can make it less visible - but probably never really get 100% uniform and without ANY visible line when put under a harsh light. I’ve been thinking a lot about it… maybe I’LL come up with an idea to make it different.

That is very kind, thank you! Welcome to the channel and have a lovely Christmas 🤶🎄🎁🎉🎊🥂

My goodness! I wish! For me, a documentary only feels like a REAL documentary when it has Attenborough’s voice. He is awesome! Thanks ❤️

Hi Dude! Yeah man, so true! People are commenting I should try POM nuts - I’ll give it s shot. Merry Christmas my friend! 🎄🎁

@@GeekDetour Polyamide (PA) is a very durable material, I have often seen a polyamide gear wear out a hardened steel gear! This material only seems weak, but in fact it is one of the most wear-resistant polymers

I've been using 3 of the same printers for over 3 years, they all have the exact same backlash nuts they came with. 6 months ago, I cleaned them for the first time. Still working perfectly.

@@LampDoesVideogame that's awesome. Not sure how often you print or if you're just still within tolerance but I can assure you it's a wear part, that's how they're designed. They're made of soft brass.

Oh, thank you! 🤗 I guess there will be always a lot of people debugging this problem 🤣 Merry Christmas 🎄🎁

I watched all of them - love it! And in my mind all the 3 printers would immediately show the wobbliness in their prints starting to when I tightened their nuts. To be clear: on a very close inspection, it happened - but it was SO DISCRETE that was impossible to see it clearly on camera. The prints were in essence “perfect” or perfectly acceptable and nobody would point the finger and say: “what happened here?”. I wanted to show a guaranteed disaster and… depending on the printer you have, it might run just fine even with coupled nuts. Makes sense? But I will definitely start modding these printers just for fun - didn’t have time to do it this year, but in 2024 I’ll hack them to my taste.

​@@GeekDetour i went to Oldham couplers a month after buying my ender 3 S1 because the wobble was bad enough to impact tolerances on parts I was making. Prints look way cleaner although I still have some inconsistent layer stacking due to the extruder gears not being perfect. But i honestly didn't mind it as much until I got the vzhextrudort on my custom build which just made the sprite extruder look like shit in comparison. But I guess every print looks shit when you shine a harsh enough light from directly above.😅

​@@twanheijkoop6753 You shouldn't need oldham couplers. They account for radial misalignment. A 3D printer shouldn't have significant radial misalignment as it uses the motor shaft and bearings as the support point. They do have angular misalignment because the screw isn't inline with the shaft and the printer isn't usually aligned to it either. But the flex coupling accounts for that. An oldham would require a bearing to hold the shaft as well. Another problem is if the printer supports the screw at both ends. It should only be supported at one end and by the nut, or the out of straightness will cause z-wobble. Optionally if both ends are supported, the nut must float free, only two points of radial constraint are allowed to not over constrain it and cause lateral forces. To minimize lateral forces the motor shaft should be parallel to the gantry frame (z). This could be measured by removing the coupler, mounting an indicator on the gantry, measuring the shaft, and moving it vertically. Turn the motor mounting in whichever direction eliminates the misalignment. Shims (paper would likely work fine) under the motor mounting may be needed. Then check the motor 90° to the first direction and align again, and then recheck the first direction. The motor being aligned will minimize bending of the flex coupling and side loading of the gantry as it flexes. Next straighten the lead screw as best you can. Roll it on a flat surface like float glass and gently bend it straight if it is pretty bad. Shim gauges under the middle can help you get it even straighter than you can see. Really this and runout of the coupling or motor shaft are the only things that should cause z-wobble. Misalignment will cause forces on the gantry, but they won't change as the shaft rotates, so won't cause wobble. The nut needs to be aligned to be centered with the motor shaft when they are as close together as you can get them. Loosen the nut screws and run the printer all the way to the bottom. Hang the nozzle off the edge of the bed if you can to get even closer. Then tighten the nut screws. I don't have any troubles with this on the cheapest E3 made. I didn't bother straightening the screw, and the free end wobbles visibly as it rotates. But that is OK as only two connections don't transfer loads.

Absolutely! MIRAGE3D videos are a MUST! Thanks for the POM suggestion, it will be in my list to try out!

No prob! Hope they'll help you out. 😁

Oh, it has been printing nice since I recorded the incident. BUT I love to tinker

I hope you can fix it to your satisfaction 🤞🍀 Merry Christmas Steven 🎁🎄

Oh man, extruder issues are a whole category of demons! It really needs to be precise otherwise it is pure frustration.

Thanks Tyler! A few people were not happy that I spent half of the video showing what was NOT the problem… but I think that’s valuable, because many “defects” look identical, but have very different roots… Showing just one ends up in a bunch of VERY specific videos. I am glad it helped you ❤️

I loved “shamanism” It works. Of course 🤣 Merry Christmas my friend🎄🎁

You definitely don't want to leave them all loose, it will add significant uncertainty in Z height especially if you are using Z Hop (i.e. Z axis changes direction during printing)

Hey, my pleasure! This video is reassuring me that I am not a dumb guy making a video about something everybody already knows - or won’t care… I really appreciate the message! Welcome to the channel 👍❤️

4:40 He didn’t tighten the nuts. He LOOSENED them and made it clear they should be loose!

This sounds like you fed the subtitles to ChatGPT and asked it to mark chapters

You just wrote two different titles that contradict each other... "Loosened lead screw nuts to fix Z-Wobble" then "Tightening the nuts resolved the issue". Huh???? He didnt tighten the nuts to "resolve the issue" he was just trying to recreate it which helped him conclude the different factors that may have combined to cause the problem.

Yeah, that’s the take away here! Troubleshooting and maintenance 👍 Merry Christmas 🎄🎁

So great that you liked it 🤗 Very often I get the opposite in some comments: “Hey man! Go straight to the point! Don’t tell us a story!”

So nice to know it helped you, even when it was not the very same culprit of mine! Thanks for sharing. Yeah, wavy layers can happen for several reasons and in that occasion, for me was the un-lubricated lead screws and nuts starting to bind - but I don't want people thinking that's the only reason, because definitely it is not.

My pleasure man! Thanks for sharing!

Hi Andre, Andrew? 🤗 Thanks man! I am glad it came for you in the right moment 👍 Please tell me later if it worked! Merry Christmas 🎄🎁

Why dont you add more printers?

@@indalecio21 the reason im limited to 5 printers is electricity and space. We keep them all in 1 office to regulate temperature and while we could fit more on the tabls there is only only enough circuits for 5 printers and a laser. We had plenty of time before prints are being used so rather than dedicate another office to printing im just playing the slow game lol. Also we normally dont do large volume printing so i dont want to be stuck with 8 machines that wont get used.

Keep it lubricated, don’t let it stay unused - I like mine a lot.

Great to hear that! Welcome to the channel and Merry Christmas!

Oh! So great it helped you! Thanks for telling me! Merry Christmas 🎄🎁

The screws on the LeadScrew Nut must be loosen. The nut must be able to move sideways.

@@GeekDetour Yes, but at the same time, my z eccentric nuts were also tight. When I loosened both of them, it was fixed. thanks a lot again

Hey, thank you so much! ❤️ If by heart you mean that I love it, that’s true: I am completely in love with 3D Printing since I got my first printer. Now, if “by heart” you mean “by memory”, here is the trick: when I try to memorize my points and speak them out, I basically freeze and I forget so much stuff… I write down the complete texts for my videos - when I record, I am actually reading. English is not my first language, so, I use a teleprompter 🤗

@@GeekDetour I meant overall work: 3D print engineering and also video recording. Keep it on! P.S. English is not my native language also. Hello from Uzbekistan 👋👋

Wow! That’s… awesome! Cheers from Spain 🇪🇸 (I am actually from Brazil 🇧🇷, but we came to Spain 14 years ago).

Thanks! What you mean man? It happens to you too! (ha ha ha, I hope) I just like to talk about them 🤣 Merry Christmas @UncleJessy Always nice to see you here 🎄🍾🥂

Amazing story! Thank you so much for taking the time to write it down and share it with me/us all ❤️ I enjoy troubleshooting - and product development seems SO COOL. Unless everybody is with a tight deadline 😬

I am so happy you enjoyed the video - and Welcome to 3D Printing!!! You probably already figured out how addictive this thing is… be careful: one printer becomes two… then 4… you risk getting a divorce or having to move to a bigger place 😄

@@GeekDetour woahhhh didnt expect a reply from you! It is very addicting. I doubt the divorce part since my wife is enjoying it more than I do. 2nd printer is on its way even tho I havent mastered this one yet lol. Greay channel and great vids! Looking forward to more of your content.

That’s beautiful! 🫶 Enjoy the printers, my friend. And if you spend some time watching tutorials, learning Fusion 360 (you can create a free hobby account) is will 100% be worth your effort. It is such a satisfaction to design your very own functional parts and do nice fixes and improvements in your house. Have a beautiful 2024 🥂 More videos coming soon!

Thanks!!! I’ll keep doing it, yeah! I love making videos about 3D Printing and Arduinos (I am neglecting Arduinos, I have so many things in my list!)

I am so happy you enjoyed it even without having a 3D Printer. Please, stay far from the printers… you’ve been warned! Extremely addictive hobby 🤣

Hello! Happy 2024 🥂🎉 Oh, I am so happy my vídeo helped you in your journey! Thanks for letting me know! Welcome to the channel! I have lots of 3D Printing experiments on the go - they take time, but I am very optimistic because I finally have a much better space to work 🤗

You're very welcome! 😂 I am happy it helped you!

Oh, I am happy you mention that - yeah, these videos take A LOT of time to be made 😅

Thanks! It means a lot to me ❤️ Merry Christmas to you and your loved ones! 🎄🎊🎉

The advice is correct, for structural things. The body of the printer should be as rigid as possible. But v-slow wheels have an ideal pressure: should just tight enough to not have wobbliness, but tighter than that is bad. The z-Nuts on the ideal world should be tight. But in most printers, having them a bit lose allowing free lateral movement is better than really tight. One thing is certain: lubrication is really important.

Oh, thank you! Very kind words!! I hope you had a beautiful Christmas 🎄🤗

I find his voice annoying.

When we are having a problem and someone helps us to fix it, feels like a Christmas Gift, doesn’t it? 😁 🎄🎅 🎁 Thanks!

Happy to help! Happy 2024! 🥂🎊

Your video deserves more attention, all others says to get tighter, but you the opposite one.

Thank you VERY much for letting me know how it helped you! It makes me supper happy!

Oh, this video is getting traction very well - I think it will reach the attention it needs to change most of the (bad) advice people share around. It is not the first video telling that the nuts must be loosened - but it is already, by far, the most watched one in the topic. I cannot ask for more 🤗

Oh thank you so much! Specially about the voice 🥰 🤣 Merry Christmas 🎄🎁🥂🎊

Oh, thank you! That means a lot to me; because it is true: some videos get in the making for many months until I get the idea mature ❤️

Thanks!!! It means a lot!

I am so happy it helped you!!! ❤️ Thanks for letting me know!

Thank you! I hope you can figure it out and have great prints soon! 🤗

I am so happy that it helped you!! 🤗 Happy 2024! 🥂🎊🎉

It is a very nice book! Sean surely put lots of time into it!

Hope you enjoy it! 🤗 I bought mine in July and only now I had the right video to go with it 🤣

also didnt know those nuts were supposed to be loose

Glad you like it! 🤣👍 Loved the comparison 🤣 Merry Christmas 🎄🎁 and welcome to my channel!

Oh thanks! Merry Christmas 🎄🎁🤗

My pleasure to help. Important: on the video I showed some of the most popular reasons that can give you this type ugly result. It doesn’t mean yours WILL be the same. Check the mechanics, be sure everything moves smooth without play. Dry your filament, do the PID calibration once (learn how to do it for your printer) and be sure your Z-Nuts are not tight. I hope you can find your problem and be proud of your improvement. Oh, lubricate the rods 😄 Merry Christmas 🎄🎁

Than you Adrian! Oh man, I hope you can give it a new try again soon - there are amazing new printers that give you excellent results with little headaches. Bambu Lab sent me a P1S and it is such a great machine. Sure, everything needs maintenance to keep working fine. But their profiles are so well tuned… it is a breeze to print.

@@GeekDetour I think the ender 3 is still a smart choice to start in this world, but as you say (totally agreed) there are more new printers, with better results and less headbaches. Greetings from Spain!

Greetings from Guadalajara (Spain too 🇪🇸) 🤣

Oh, THANK you!!! Sound is so important to me - but it goes pretty much unnoticed (at least on a conscious level). You made my day ❤️

I agree, ha ha ha, for a different reason: I was desperately needing a video with a certain amount of views - this year was very challenging. This one saved us for a couple of months! 🤗 Merry Christmas 🎁🎄

Thanks!!! I am glad you enjoyed the game ❤️
