I will never talk about Z wobbling ever again !

That design is impressive ! I saw your early attempts at fixing the wobble but never saw that solution until now, crazy smooth.

It’s kind of amazing how the most minuscule vibration/etc will become apparent in a print. Though it would actually be cool if it could be taken advantage of since sometimes the effect actually looks nice without being part of the design itself.

Mirage my first experiments with the Rat Rig V-Core 3 started with an adaption of your very clever wobble rings. Subsequently I developed the VenterMechs (Simpler and less fiddly than Wobble rings and results were just as good - hundreds of people using them) and then I upgraded the Rat Rig I was using as my test bed to the 1P Z design to also eliminate the 'hula' movement, which other designs don't address very well. This design has proven the best yet. The design is open source for non commercial use and I don't sell any parts for it. I wrote a series of articles on the popular Z designs and the issues and fixes for them including the 1P design.

I always wondered if you would come back around to the wobble wings you first shared. You're doing some great work in advancing the small things that have big impacts in 3d printing.

I really like mellow's parts, they are expensive, but people say something about getting what you pay for... Congrats on succeeding on creating an awesome product!

I think this is a fantastic example of a good mechanical design to solve the issue rather than a software patch to try and fix it.

I've never once thought about this type of wobble while printing.I just thought the slight variance was due to the unavoidable motion created by moving the print head. Absolutely mind blowing to learn you can get near perfect finishes on printed parts without sanding/finishing.

amazing! I love how much the community help each other out and come up with amazing ideas then share them! Thanks for taking the time to create and put it all into a video :)

I know you are beating a dead horse, HOWEVER i super appreciate the systematic approach of testing and validating mods. Too many it seems are done in the name of performance, but end up causing more issues that they fixed. I'm currently trying to print as fast as possible with the best quality on ender 3. Lack of time does not allow for the cool stuff like voron.

Reminds me of a documentary I've seen many years ago about how some bridges in quake-prone areas decouple their structures from the ground using large bearings in concave cavities to make it self-centering.

Wow, great video. I built a ~2000mm tall bed slinger, and wondered about my artifacts. This is really great. Thanks for making these available to purchase.

You and the community are amazing for such solution!!! I'm especially happy that's also available for common bed slinger's lead screw!

This is a gift to the printing community. Thanks!

I seriously love following this not only as a Mechatronics Engineer but now I’m torn between a design like this or Voron so hard to decide now

So glad I found your channel. This hobby desperately needs more evidence based examination of "known" things. I especially like that you're not afraid to show when one of your hypothesis turns out not to work (as in the extruder gear issue for example).

This is so awesome man! Been following this journey for a few years now, and I'm glad to see it concluded

A great way to add precision without making everything from cast iron and concrete. Will be checking out those 8mm ones.

Thanks wobble man, instantly ordered 3 WobbleX. Been fighting with the Z wobble for 3 years on my custom printer. I will soon add a custom mount for the Sparkcube XL.

the sound of the stepper motor slowly moving the screw and it being affected by the screw wobble is satisfying

A very elegant solution. I was actually designing something like this for my Ender 3. I used ball bearings from motorcycle parts and the pins from an old DVD writer I had around. I made some prototypes but stopped once I learned that Oldham-type nut exists.
