A Mod Your Budget Printer Doesn't Need: The Lead Screw Stabilizer
Vložit
- čas přidán 5. 09. 2024
- In this video I explain why I don't think you should print and install one of the seven hundred gazillion Z axis lead screw stabilizers available for your ender 3 or similar budget printer on Whateververse.
This is just about my opinion on a specific and common 3D printer mod. I don't make anything in this video and I talk the whole damn time. It's a bit of a departure from my other current content. I hope my channel can be a little more informative and maybe bear discussion, as well as make cool stuff and abuse the CZcams free music library.

One of the first things everyone seems to do is over constrain the lead screw which shouldn't be done. You're exactly right, they are supposed to float, even the nuts intentionally have play.
I upgraded my Z to 800mm and dual z screws and I had to take off my stabilizers. It's amazing how much trouble they were causing for me. I learned about this myself and I'm glad you made this.
800 mm?? which printer?? the ender 3 thats insane
Thanks for the info. This makes a lot of sense. It seems very possible this could be the culprit in some prints where layers don't quite line up.
Thanks for all the great information on the Z axis. I did note that I was distracted a little by your hand always being in the middle of your video. Just my penny's worth.
Thanks for the feedback. Hope you still enjoyed the video.
@@makerunderground I'm always trying to learn and your content is top shelf. Thanks Again Doc'
The one scenario you DO need leadscrew stabilizers at the top is if you're running a dual-z setup with a synchronous belt to keep the two sides in step (pun intended) with each other. Without them, you can't keep the belt in tension. I feel it would only be fair to make an addendum acknowledging that scenario.
The beginning of the video specified that we are talking about entry level printers. I already specifically acknowledge that modded printers and higher end printers have different needs.
Thanks for the feedback but I completely disagree that an addendum is required.
Had one more thing to say. Most people don't realize they are supposed to lubricate their z screw. If you do, you save the life of your brass nut.
Dual z steppers with belt and top bearings using flex coupling and alloy mount. The only reason there’s an issue is the bad plastic gantry mounts move steppers out of alignment. If your gonna mod you’ve got to do it all
I agree, there is definitely a right way to do it. As you say, it involves a lot more than a $2 bearing and thingiverse file.
Yeah, that really makes sense. I would've wished that I found you video before I printed the accessorie and bought the bearings😒
I've printed a lot of accessories for my printer that I later reconsidered. At least it wasn't an expensive addition.
@@makerunderground Na, fortunately it wasn't that expensive, but I just found another mod where I could probably get one of those bearings to good use. It's a filament roller guide, and I guess it's actually useful unlike that lead screw guide.
Anyways, thank you for the video👍
The ball screw in my Monoprice maker ultimate (Wanho D6) printers have error in the motion such that is ruins the sides of the prints. I measured the motion and the screw itself has a cyclical error. What ball screw brand would you recommend? The prices go from $15 up to $700 and it's hard to know what will be accurate but not overkill. The motion of the lead screw in my Prusa is spot on accurate when measured with my digital caliper. You get what you pay for sometimes.
i saw a video on magnetic motion decoupler for cheap ball screws a while back i dont remember what the video is called off the top of my head but it shouldnt be hard to find.
Sorry, I'd love to say I have a great answer for you but I'm just not familiar enough with the specific brands. Good luck on your endeavors!
If it's the sideways motion that is the problem, maybe you could look into mounting the nut (or what was it called for ball screws again) on an Oldham coupler: they transfer torque put allow the part slide in X and Y, with constrained Z. Saw it being used for Z lead screw nuts just a while ago.
👍👍👍👍👍
cool
No comments I accidently clicked it
Oh crap... uhhhhh sorry misclick :)
