Something most don't know about stepper motors: Inside them is a spring-washer type pre-tensioner, it preloads the motor and keeps it from rattling if you shake it, guess what side it's usually on though? The bottom(bushing upwards when used in the z-axis like this), your gantry weight might be sufficient to deflect this spring and cause irregularities if things are heavy enough. You can tell by watching the coupler while giving it a little push down against. Your thrust bearing is probably fixing this. On mine I took the motor apart and relocated the spring to the top so it pushes downwards instead, resulting is a notably more stable Z-reference.

@@moodberry Very late to reply, but you can check for it by literally pushing down on the shaft of a stepper that's pointed up, if it visibly deflects down into the motor and it's being used on a Z-drive for anything supporting weight.. then that basically means it can get forced down like a spring and cause uneven settling heights. Visually it looks just like a washer but has a 'ripple' indented into it, so it isn't flat.

"Self lubricating" is code for "material lost to wear acts as a sort of lubricant".
@m3chanist
@m3chanist 7 месяцев назад
No, it's material dependent. Stainless steel, titanium, glass for instance aren't "self lubricating" no matter how they wear. Brass, copper, white metal alloys are, because unlike those, they shed flat plates that slide across each other. Same for plastics, nylon, ptfe, UHMW, POM/delrin contain internal lubricants that are only released with wear, some are even impregnated with oil, they all need an initial break in before this happens. PLA, ABS to name but two, do not.

@@m3chanist Wh "no" , what i say wrong? Of course worn material can be either a lubricant or an abrasive, both is possible. Besides very confused comment. There aren't "internal lubricants" in the plastics mentioned, it's purely low surface energy causing the material to be low friction, chemically induced property. PTFE PA etc are not impregnated with oil.

The thrust bearing is important for another reason. The motor has a spring inside of it, allowing the axle to move up and down a little. By placing the thrust bearing between the coupler and the motor body, this freedom for the lead screw to move slightly down is eliminated, and it will unlikely to move up because of gravity, but if you really want to make sure you can go overboard and put a thrust bearing at the top of the printer as well to really constrain the lead screw Z motion.

EXCELLENT video my guy! I have 2 Ender 3’s and I have dual lead screws on both of them along with direct drives! You have explained what I have been having trouble and have noticed! I have noticed the screws are really not lined up properly, and it’s just a few mm if that. And that really makes a difference. The trouble with belts is that they are like chains on a bike or motorcycle. You can only tighten them so much until you’ve stretched them all you can and have to replace them. So belts (in my opinion) are not on option for me. Any way great video, subscribed!

The most critical thing with leadscrew alignment is that the bearings and nut are all in *exactly* the same relative position to the linear axis the screw is driving. The screw being straight is irrelevant if the top & bottom bearings are at different distances from (or laterally to) the linear slide! That is probably why the top bearing caused problems - the opposite end was not in line with the nut, so it was causing lateral force on the nut near the ends of the travel. It applies to the industrial machine tools I work on, and equally to 3D printers or any small CNC.

The #1 most thorough set of tests/results and solution options on YT. My issues are around z-binding (mainly), with no discernible pattern in the layers. It's been a total pain to trace down and I'm pretty sure it's a combination of the anti-backlash nut and sub-standard linear bearings, but good luck trying to find a set of well made bearings that are any better than what Creality uses. Again - really good video and I've subbed.

Note that brass oldham couples like the ones you showed aren't supposed to work well under compression, when an oldham coupler that responds well to compression is installed the lead screw isn't constrained laterally at the X axis, in those cases constraining at the top _is_ a good idea because otherwise the lead screw is underconstrained. There are bearing-based oldham-style couplers like the "wobble wings" and the suchlike that are designed to work under compression, also bear in mind that thrust bearing are great but can introduce vertical motion in the lead screw if they are not perfectly perpendicular to the axis of the lead screw, which can be tough to ensure

Bent lead screw itself wont deflect in travel at any noticeable rate, extremely small effect (a2 + b2 = c2). Most Z issues are simply binding from being out of square, the rest are bad PID tuning (temps jumping around) and bed bounce/vibration, mostly just on bed slingers. BUT if you have dual Z motors and there tied together with a belt and not in phase, it's better to simply unplug one if that gantry holds up when turned off. If you need both, loosen one coupler and activate the motors then level your gantry and tighten it up. That will put them in phase so that there not constantly trying to fight each other paying a back and forth tug of war. The last one, a loose carriage. The POM nuts work just fine and can be "loose" as gravity will do the job of keeping them in place, maybe if you need to print while its on it's side.. idk. The thrust bearing would compensate for bad/cheap bearings in the factor motors, but you can get nearly the same effect of the oldham with nylon washers and only tightening the brass nut so that there's no play, allowing to the stock cheap brass nut to move around in the x/y AND also wobble to play along with a bent lead screw.

So hope this fixes it and maybe one day i'll upgrade to something like a RatRig

In my opinion & experience as long as we let the top end hang free and allow the linear rod to hold its position. Best is increase to 10mm rod or use linear guide the Z. I use a PLA printed z Lead nut and it really zero down the blacklash. Sometimes some parts of the machine need NOT be metal to cut out vibrations and noise. Part of your printed band seems like uneven extrusions not totally z-band. I am not sure about converting to belt to stop my blame on the Z-Leadscrew bend. Anyone tested can share your views too. Bear in mind Z is the least movement axis among all bed slingers. Thanks for making this well presented video ❤

Thank you for sharing! Good idea about the thrust bearings, something I haven't tried. I recently just installed a dual Z axis stepper motor kit, the box says it's from Creality, but I'm not sure if it's authentic. Anyway, the kit I bought came with anti-backlash lead screw nuts aluminum mounts for both stepper motors. I still had to put a shim for the originally located stepper motor, but no for the other side, I'm guessing the gantry bracket for the original spot wasn't drilled properly or bent at the correct spot. When I was aligning the lead screws with the stepper motors, I left all the mounting screws and lead screw nut loose first, and also moved the X axis gantry all the way down for better alignment, I even removed the printer head so I could go as low as possible. I didn't know about the top mount could cause issues. When I installed mine, I moved the X axis gantry all the way up possible, so that the top mounts are aligned the best way possible before I tightened them in place. I might leave mine in for now, as I don't see any Z banding issues with my prints.
@cowboy124aa3
@cowboy124aa3 4 дня назад
Thats all fine and dandy but some Z Banding, wobble, whatever can also be caused by the wheels on the x gantry riding on the frame if they are not perfectly round. They can cause z banding, I've tested this extensitivly with my original ender 3 that didnt have duel z screws. After disabling my Z motors in the printer screen, you raise the gantry up and down with two fingers and if there is any resistance as the wheels go up and down you have an issue with a flat spot on the wheels. The issue can be very slight so you have to really get a good feel for how the wheels feel against the frame. This can happen more then not when the printer has been sitting for extended periods of time not being used, the tight wheels will deform over time against the Z extrusion frame. This can even happen when putting the printer together if care is not taken when mounting the X gantry and the wheels are grouged when fitted onto the z extrusion frame. Lead screews can be a problem but could also be other issues.

You see your problem isn't the lead screw at all. Mine is bend but there is no sign of wobble on the print. I have done all "bad" practices. Fully tightened the POM lead screw thing to the frame while you are supposed to leave it untightened. I added a bearing at the top which is supposedly really bad but I need it to stop the lead screw from vibrating with my high acceleration. The problem instead is Creality leaving the screws too loose from the factory. Specifically the ones holding the Z Gantry so technically the X gantry. There are several screws that you can tighten to lock the parts with the V wheels. Essentially you have to first make sure your X gantry is level then fully tighten the eccentric nuts so that the inner wheels are jamming the outer wheels. Then tighten the brackets while making sure it stays level. After that you can untighten the eccentric nuts again and check for play. If you have done it correctly your X axis doesn't want to wobble anymore it will want to naturally be straight. After that you can tighten the eccentric nuts to the correct spec so slightly touching but its really not required as the outer V wheels will do all the work. What that does it prevent jamming on the lead screw as your X axis will always be level. I think you are putting way too much thought into it while for the Ender 3 v2 Neo (my printer) there really isn't much to it. From the factory there was 0 banding. I replaced the brass with POM because it promised better accuracy and it indeed only has 0.05mm difference between moving up and down. As long as you move the same direction its 100% accurate. Only when going up then down vs only going up does the 0.05mm come into play. Also my printer needs 398.94 steps per mm instead of 400 for the Z.

@@MaxyMeanderings Those are some fantastic choices! As far as linear rails I was reading KevinAKASam's (belted Z mod creator) documentation for the belted z and he advised against it. Reason being is the POM wheels allow you to tighten the concentric nut and create friction, where as the linear rails have 0 friction. Problem is with only 1 stepper holding the entire X gantry, the X gantry will fall once the printer is turned off if the Z axis has linear rails. Having that friction from the POM wheels ends up helping the single stepper hold the gantry in place, or at least gently bring it down.

i looked into oldham couplers 9 years ago for my 3d printer and they weren't available in a usable size. they were also expensive.

I was really wondering, why there were no "lead screw stabilizers" on my Prusa. Seems like they had done their homework.

Friendly reminder to always check the parts you know are "working" first...because that's usually the last place you'd look for a fault.

🎯 Key points for quick navigation: 00:23 *🛠️ Z banding is a common issue in 3D printers caused by mechanical problems with Gantry and lead screw.* 01:50 *🔩 Z binding can cause ribbing in prints due to missteps on z-axis lead screws.* 03:43 *🧽 Regular maintenance like cleaning and lubricating lead screws is essential to minimize Z banding.* 07:26 *🔧 Leveling Gantry and ensuring motor mounts are square can help reduce Z banding.* 09:33 *📏 Ensuring lead screws align with motor couplers is crucial to prevent Z banding.* 13:18 *⚙️ Consider the type of nuts used (brass vs. palm) and lubrication to reduce Z banding.* 16:54 *🏗️ Lead screw covers can protect the top of the lead screw while allowing rotation.* 18:49 *💲 Consider cost-effective solutions like oldham couplers and flexible couplers to address Z banding before opting for more expensive options.* Made with HARPA AI

12:31 Is the way you have the oldham and POM nut stacked optimal? All of it under the aluminum bracket and the POM nut at the bottom?

Excellent video; Z-wobble can be a real PITA to resolve, especially for n00bs, so this should be a great resource. 👍 Technically, POM _does_ need lubrication, but, IIRC, only if it's loadbearing, which in this application is absolutely minimal. So, even though it's not required, a dab of PTFE or silicone lubricant should be fine. There are a few types of co-polymers of POM, such as POM-C which contains ~10% PTFE, so no lube at all would be necessary. 🤓 Oh¹, and *_Old Ham_* made me both laugh and cringe in equal proportions; it's pronounced as _hold 'em,_ but without the _H._ 😂😬 Oh², how I wish I could run this video through an audio filter to replace every _"ZEE"_ with a _"ZED",_ but that's a _me_ issue, lol. 😜 Subscribed!

Nice repair chap, think the caps may not have registered as it takes time to charge and those small testers time out

Imo, spider coulplings are a terrible option for anything CNC. Adds extra play and backlash, which is not ideal (even compared to stock sleeves that are not of a great quality). They're great for something like a centrifugal pump coupling though, lol.

the lead screw in ender 3 series is 365mm. Nema stepper motor with integrated lead screw have a max length of 350. Can these missing 15 mm be a problem ?
@MaxyMeanderings
@MaxyMeanderings 4 месяца назад
The installed 350mm leadscrew stepper reaches the top of the frame on the ender 3 just fine. No Z height is lost.
