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.

I just can't believe that it's cheaper/ better than buying straight ball screws or making the frame stiffer. I don't really get this fashion of using proper linear rails and lead screws (all from aliexpress) an mounting the lot to a frame made of jelly. It dosn't seem like good engineering to me

[@Sharpless2]

@@michaelwatson7211 Cheaper? Youve never seen the prices for an actual high quality ball screw + ball nut huh? A high quality ball nut itself can easily costs more than the 3d printer itself. $400 for a ball nut is very common, $750 to $800 for a quality ball nut is normal.

[@sfproject-life3829]

Ball screw + linear rails?

[@michaelwatson7211]

@@Sharpless2 Yeah I meant lead nuts, which aren't that expensive even for OK ones. And thats only one of my points, why buy this stuff if you are going to mount it to a frame so weak it's deformed by an 8mm rod? Lazer cut steel is pretty cheap, tapping holes isn't that hard, avoiding that then splurging on custom components, and rails with a >200kg capacity is building your house on the sand.

[@liamventer]

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.

[@michaelwatson7211]

​@@MirageC I think I don't really get the problems you are trying to solve, my background is in CNC, the idea of a ball screw deforming the frame is pretty nuts, as is the idea of using a bent screw. Why don't people use a cantilever bed on 4 bearings with a single screw (I've seen this with 2 bearings eg ultimaker but not 4)? Wouldn't it be cheper/ easier to make stiff than using 2 extra ball screws, if you don't care about weight in the frame the whole thing could be welded in thick plate it would be pretty easy to shim it flat once and be done with it. I also don't think you really get any benefit from ball screws over lead screws here, there can't be any backlash becuse the force on the bed is always down, unless there is somthing strange going on with the frame deforming or the 3 screw arangement. Like I said though I don't get the problems, the costs i was using in my head seem to be about an order of magnitude more than you are spending for screws at least, maybe the calculations just all work out different to my intuition.

[@gyrogearloose1345]

Instead, how about starting with high quality ball screws and properly machined bearing ends, along with a rigid frame and precision sliders?

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'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.

[@Sulphur_67]

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

[@ad5000donnell]

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

[@EgorKaskader]

It depends on your needs, really. A Voron's quad gantry belt assembly hits its limits in size quicker than this design, and I would say that the pin mod (replaces screws as axles with hardened pins) and GE5C gantry tilt blocks instead of the stock plastic on plastic tilters are almost a requirement for high performance ones. It is, however, much simpler to isolate motion problems and there's fewer of them in the first place as belts don't tend to introduce Z-axis artifacts to nearly this extent. I'm not sure the fixed bed VS tri-screw bed is really making much difference at this scale of design.

Very great video! I have made the somewhat exact same experiences you talk about in this video. I have an Ender 3 with a single Z-axis screw. I used a anti-Z-wobble constriction from Tekti from Thingiverse as inspiration, designed it completely from scratch from CAD and use it in my printer right now. It works, but as you said at 7:30 you need to fixate both ends of the screw, so the "wobble" will be transferred to the part that is made to take on the wobble. It works very great, even thoug it is 3D-printed and uses magnets instead of little rods. So far, so good. Very cool video, I like it.

@@MirageC Yes, I had to do some iterations, but since the print is actually 3 piece and quite small, it doesnt take long to print. I sureley had some space trouble because of the extruder stepper motor. But it works pretty good, even though not engineered/desgined to every standard. I hate to go for some shortcuts to safe a bit of space ... no threaded insert but screws directly into the plastic. Works fine if you dont tighten it too much and dont unscrew it and rescrew it every half an hour.

[@heavyweight6440]

@@patrickboyd8368 Not yet. Right now it all looks kinda good, but I can imagine that after enough print hours the magnets will probably suffer the same fate as they did in MirageC's video. I also am pretty sure that Tekti has developed a different version that doesnt use magnets anymore but 2 dowl pins as guidance for the ball bearing. They have much greater HRC then the neodym magnets and will probably not suffer such a fate. But as of now, it all looks ok. I think they weight of the tray is not great enough to damage it very fast. Otherwise you could upgrade to double Z-Axis on the ender 3 and split the load up on two anti-wobble systems. This doubles the area where force is applied and the surfaces of the magnets will live much longer. The PLA looks all fine as of now. Prints also come out good.

[@BigfootPrinting]

Oliver, what are your thoughts on printers using belts instead of screws?

[@MirageC]

I don't have experience with Belted Z, Only seen user mods of them and no official design around them. I have many questions... Will the bed jump up and down as the belt vibrates from XY vibration sent through the frame? How many parts will be involved to lift an 8mm 500*500 bed and keep it up there?.... Somehow... I don't feel the need to investigate these question anymore 😁

[@dev-debug]

@@MirageC I have a custom Ender 3 IDEX, well the only thing Ender is the frame I used. I use dual side mounted Z lifts but it's not like the ones you commonly see. It runs on an 8mm hardened axle that passed under the frame. Most use flimsly shafts and mounts which can be an issue. I've seen no reaction in Z from X/Y moves on mine, was worried about it early on. It would be a pain on a 500mm cast bed, take your pick, a braking system or insanely low gear reduction. I run gear and pulley reduction at 40:1 to keep the heavier IDEX X carriage from dropping when the steppers powered off. DId the brake route first using a servo, it worked but a PIA to sync the release.

Belts are nightmare at high speed, unless you can afford to go very wide and tight. The heavier the XY movements, the more vibration will be sent down.

Z wobble isn't always the sole reason for Z artifacts or Z banding - No matter how much we compensate! There's always others factors coming into play, too.

[@onewa712]

well of course! but like, that was a HUGE reason. It's like seeing your house has mold everywhere, no electricity and also half of it is under the water bc of the latest hurricane or whatever: Sure, fungi and lack of energy are very important, but solving the issue of the flood would greatly improve your house, and also would help to solve the other two things 😆

[@NeoAcheron]

Yup... On my custom Delta printer I had the problem where the bed is static, but still experienced z-banding. Turns out it was the PSU I was using, it had a very very loud fan, that would only turn on when "needed". The fan drew enough power that the voltage dropped, causing the bed to cool a bit faster than the PID tune could kick it back up, and the expansion was enough to cause visible artifacting. Took me months to figure out.

[@onewa712]

@@NeoAcheron daaaaaaaamnnn! Awesome that you found out! Sounds like something you might not find easy at all untill everything else is correct

[@mikejones-vd3fg]

Right, i was just thinking about this, you dont really print while the z is moving up, so that extrusion line widh shouldnt be all uneven because of Z wobble. Well not all of it, thats more likely to due bed temp fluctuations, that will cause the z to change ever so slightly while is shirnking and contracting, something more probable since its happening constantly while on the same layer, whereas a Zrod problem would only show up in layer changes. And in this example here it does seem to be Z wobble since the pattern reflected the rods. But the uneven "bumpy" random lines he was showing arent z wobble, but more likely bed temp fluctuations. Same effect, different reason. Why I think its important to PID tune your bed while the fan is blowing as well so it has that constant cooling to fight against, should make the temperature more consistant.

I got so exasperated at looking for the cause of my wobbling and banding that, when I discovered that the second lead screw was going through a malaligned flange attached to the backplate, I lost it. Got unlucky with Creality's quality control (or lack of it). I stripped out the lead screws and modded the z movement to use belts instead, driven by a stepping motor on top of the assembly. It rotates a horizontsl bar via a transmission, which provides the vertical movement for the belts. Worked a treat.

[@JonS]

Nice! I can't wait to try this on my V-Minion!

[@boredKiwi]

I did much the same on a precision X-Y table I designed in 1993. The precision-ground NSK ball screw I used was very good geometrically but under high (1G) acceleration against an offset load, the ballnut would skew under deflection of the bracket and subsequently jam on the screw. What I implemented was basically a U-joint around the ballnut. Rolled-thread lead screws are pretty bad for precision but at low acceleration I suspect you could get away with a rubber mount.

[@MrHeHim]

Me sitting here with a Sermoon D1 (nothing special, just a very sturdy "bed dropper" machine) and no Z wobble, shift, banding from the top of a 310mm print. This is with one of the lead screws having a slight bend. I did the math on deflection, and less than 1mm deflection translates to almost nothing. I also tightened the brass nut screws, then loosened it 1/4 turn to allow lateral shifting but no Z slop. The bed rides on two vertical 20x40mm v-slot extrusions Two things i did, i put the bed all the way down until it bottomed out and loosened the z-rods then activated the stepper motors as to jump into phase. Then i carefully tightened the couplings as to not move them in the slightest, the stepper motor will give a little while being energized. That made the z-banding nearly invisible and you had to really really look for it. Then i did the same thing again but this time i installed a timing belt, making sure they where in perfect phase i energized the motors on and off listening and feeling for any shift. That completely removed any z-banding visible. Note; I'm using a 0.5mm nozzle and regularly print at 0.12mm to 0.32mm layer heights. I always use PTFE grease on lead screws and PFTE oil/grease mix on LM8UU bearings and meticulously square my machine. Which annoyingly exposes any slop in the bearings and makes them slightly noisy.
