Quieten your 3D printer with stepper motor dampers: Ender 3 tests
ฝัง
- เผยแพร่เมื่อ 30 ก.ค. 2018
- Stepper motor dampers are appearing more and more on 3D printer upgrade lists, particularly the Ender 3. I thought I would take the plunge and do some back to back testing to see if they quieten the machine in a worthwhile way.
Two models, same filament (X3D), same gcode. One to test print quality and another to provoke overheating. Sound, temperature and quality are compared directly for your benefit.
UPDATE: I wouldn't recommend these anymore. They still work but it's easier to change the mainboard to an SKR mini E3.

![Ender-3 stepper motor dampers with press-fit pulleys! [SUB ITA]](/img/n.gif)
This guy has a solution for the likes of us who have stepper motors with pressed on pulleys:
th-cam.com/video/IjzrNoFnbcI/w-d-xo.html
Just followed this guide for pressed fit pulley and worked great for the x-axis on my Ender-3 Pro.
For Y-axis, printing the following y-axis damper+motor mount made it really simple!
www.thingiverse.com/thing:3339725
Make a fixture to support the pulley while you tap the shaft out of it. Fit pullies that have grub screws.
@@ventilate4267 Does it still work perfectly when putting the fit pulley back on the stepper motor?
Hammer is always a solution :D I think, that this is the common issue of people from printing community, to solve every problem by printing new parts, even if its usually not really needed :)
Or go to home Depot, buy a pulley puller, pop it off in 10 seconds and return it.
WHAT? I CAN'T HEAR YOU OVER THE WEEYOOWEEYOO OF MY ENDER 3
hahahahah :-)
I can't understand how you could make that sound into a word... so accurately...
Pro tip: steal two M3x8 screws from the lcd so you don't have to buy them. The lcd is fine with the two it will have left.
Great tip :)
Geweldig, thanks Maarten
LCD dislikes this
@@TheSolderingGuy007 LCD can go fuck it self
Was litterly sawing off the 2 screws that were too long... got through one after a long time and gave up... then i see this
Just added these to my E3 and printing a calibration cube now... can't believe how bloody noisy those fans are! The steppers are practically silent now. Great upgrade!
I noticed that using the packaging material is excellent noise-insulation to put under the printer. Just cut around 30cmx33cm plates and put them under the printer. I recommend using 2 layers, as the first one will get mushed after a day under the printers weight. 0 cost and no need to print anything. This removes massive amounts of vibrations against your table and so makes the printer quieter - and possibly improves print quality also. Combined with these dampers the results are fantastic.
I just got my first 3d printer, the ender 3 a few days ago and have been watching all your videos learning so much. thank you for uploading!!
These are my favourite comments. Thanks for watching and welcome to a great hobby :)
Same here, haven’t finished assembly yet and have been watching (and enjoying) all of your informative videos. Thanks for making this entry fun and easy, you’re doing a great job!
Good job on using data to truly show differences.
I just added these to my old Printrbot Simple Metal, and they made a huge difference - even after a bunch of other upgrades including a Duet Maestro, quieter fans, and placement of the printer on a large concrete paver isolated on top and bottom with felt pads. Well worth the money, highly recommended.
I used 3 on my Tevo Tornado and it is amazing - it used to be a symphony of weird sounds, now the next loudest thing is my control box fans. Someone recommended using rubber washers as well.
New Ender 3 Pro user here, love the videos... any research I do your videos are the first I click on. Thanks a bunch, keep up the good work.
Your tests are so relevant and thorough, thanks again!
Really helpful. My package has arrived and Installing these today.
Thanks.
My stepper dampers arrived last week, I must get round to fitting them :)
I absolutely agree with your results. These things did the most for reducing the resonance noises in my custom Anet A8/i3 metal clone. I have the DRV8825 drivers.
Glad it worked for both of us.
I got great results by using Clip-on Ferrite Ring Core 9mm (2 on each axis) and 2 on the main power cord. Also I added 2 32x3mm round n52 magnets to the Ring cores.Things just Quiet down. Now I have smooth walls on my prints. Stabilizes the stepper motors.
Very thorough and well structured video. Thank you Sir!
Exactly what I needed to know! You are easily one of the BEST 3D printing channels out there!
Hey thanks for the tips man. This is very useful. I just acquired a 3D printer and all your tips are very useful to a newcomer :)
Hi and thanks for awesome 3d printing content. A question, have you mounted stepper dampers on a ender 3 Pro?
Hey Michael thank you so much for this video, I have one question, would you recommend changing the stock nozzle fan (Of my Ender 3 PRO) for a Noctua one?
The I3 plus has these installed for the z axis, which in turn basically helps silent the entire z and x axis. The idea of this is not to quiet down the z steppers, but to actually absorb the vibrations caused by your extruder assembly like x stepper, e stepper as well as the fans. Really smart by wanhao tbh. However, I tried installing these aluminum spring couplers for the lead screw and this reduced the noise from my machine considerably. Theyre like $3 each and I really do recommend them. The loudest part on my machine is the Y-stepper motor as it is hard-mounted to the frame and I have ordered these dampeners to help fix that.
I just got in a set of dampeners and only put one on the Y axis. I was blown away by the noise reduction.
a 5db drop is far higher then you think, you needed to graph those levels using a logarithmic scale as dB is a logarithmic measurement. For every 3dB, you have reduced the volume by 50%.
This video is so well made. Great job!
Thanks very much :)
They should be nearly a standard thing on most 3D printers going forward along with X and Y heatsinks. Printing over the southern Aussie winter I haven't worried about the heatsinks yet but I will be adding them soon. The Dampers on my CR-10S work great.
On the extruder without adding an upper bearing on the main shaft I would be worried about deflection and loss of accuracy/slipping.
Thanks for watching, two good points.
Great vid. I ordered some of these and didn't realize one set of holes was threaded. Had it installed backwards and couldn't figure out how to attach it on the other side.
A fair enough mistake (although still funny).
Great video. Complaints at home from the noise so I will be getting a pair of dampers. Many thanks
It really does make a big difference.
Great video. You have the best ender 3 series on TH-cam. Would you still install these dampers if you were going to do the mainboard/silent-stepper upgrade?
great video as always!
thanks for the videos. you do a great job
Hi, thanks for this amazing video.
Just one question: You mention that your extruder is making this high pitch noise, and it is the same as mine.
I'm new to 3d printing, so I was wandering if you would know if this noise could be reduced by some setting in the slicer.
I'm also going to put the damper into the extruder, but I would prefer to have it without this annoying noise if possible (right now this is the only noise I can hear from the printer).
I bought an ender 3 from a friend and he had uninstalled dampers with it but I didnt know what they were until now. I just set them back in the box. Going to install them when I get the chance.
Maaaaaaaasive difference in sound! I wish I would have done this before printing all of the parts for the MPCNC, I thought my wife was going to shoot me!
Are you still alive lolz =))?
Is the overheating an issue?
😆
Currently here because of my GF. She slept through a 23hr print, I was awake all night making sure...need these ASAP.
Straya! One thing to note (I have a CR-10S) when you mount the dampers with just 2 screws, the gear head(? not sure what else to call it) on the steppers that the belts attach to, will bend towards the belt drive ever so slightly. I had to square the steppers with zip ties to the frame to pull in the opposite direction of the belt so the gear was a few degrees taut the other way. If it's not square the belt will rub on the gear head(?) walls and make a weird zipper noise. It will most likely wear the belts much faster, and cause extra friction. I tried to just loosen the tension a bit on the belt first, but my first print was slipping on the gear head occasionally. I only put dampers on the X and Y axis as there was no room on the dual Z steppers. The Z also doesn't seem to make steps nearly as much as the X & Y. As for the E stepper, I had extra short screws and nuts, and mounted the top extruder parts to the E bracket where I could, and it works just fine. Just make sure you have screws that clear the gap from the stepper and bracket. I wonder if cut sheets of rubber would work for the dual Z steppers instead.... Anyway, great video!
Thanks for the detailed post. I haven't noticed enough flex to need that intervention, but your solution sounds quick and easy. I guess each brand has slight variation in the amount of flex.
@@TeachingTech could be the brand of dampers. My rubber on the dampers could be softer, leading to more tilt on the stepper.
Creality updated the Ender 3 from my earlier version. The y axis needs a 3D printed adapter to fit. Search Thingiverse: www.thingiverse.com/search?q=ender+3+y+axis&dwh=465bbd91dc53144 and pick one. This is still a fantastic mod, highly recommended.
Update: Several users are posting that the pulley is permanently fixed on the stepper motor shafts. Please check for this before ordering the part because it will make fitment near impossible.
Have yet to do this mod but am planning to. Any suggestions on which adapter is best?
I don't sorry, haven't needed it on either of mine. Lots of suggestions in the comments below.
Implemented the y-axis fix with this adapter. www.thingiverse.com/thing:2879245
Very happy with the results!
@@toddd.8496 Thanks for sharing that link.
Ganhou mais um inscrito.
Thank you! This is the only video I have found that let me know there are screws under that stupid sticker!
Great results! My Ender 3 arrives tomorrow, and I hope the dampers soon after. I think'll do the fans too. And maybe somewhere in the future the board even with some TMC2130 drivers to get it even more silent haha.
Quiet printers are underrated. One of the best things about my mk3.
Best thing a bought well worth it no more vibration and no sound except the fan of the psu
Agreed they work great.
I experienced a very hot extruder situation and had to add fans to my motors for a i3 prusa ..I measured the supply voltage and it changed from 12.5 no load to less than 12 V under full operation .When I adjusted the power supply back to 12.5 under full load operation the heat stopped occuring in motors and they ran cool..You can add a heatsink for the Y as it sits under the heated bed and helps. Not aving fans helps the heated bed maintain constant temperature.
Good info, thanks for sharing.
Not sure why you only have 8k subs. Your videos are very informative and well produced. Let's just ignore the before-->before mistake in this video :D
Those mistakes getting through drive me crazy. My channel is tough and growing quickly compared to other channels this size, thanks for the positive feedback.
now you need to place a dense rubber pad under the printer and watch the remaining noise not amplifying off the table too. I did that
If so stumble across one in a shop I will test this.
@@TeachingTech yoga mat
Use the packaging material that came with the printer - tested and it works like a charm!
@@TeachingTech I just installed stepper dampers on my Tornado and they were great, but the biggest drop in sound I got was from putting the printer feet on rubber pads. There are also printable vibration dampers on thingiverse and some even use squash or tennis balls. You should repeat this test with those in a "how quiet can I make my 3D printer" video :)
@@TeachingTech www.thingiverse.com/thing:2913473 you need to test those. Their supposedly making a massive difference in noise level.
Currently printing them out myself.
What if I can’t unscrew the gears on the stepper motors
My damper made my motor stick out further under my build plate, and now I had to adjust my Y-Axis stop switch forward in order to stop the build plate from colliding with the motor.
Probably worth mentioning you will lose build volume from this.
Please see the pinned post.

I ran into the same problem... how did you end up fixing this?

HI MICHEAL MY ENDER 3 2018 MODEL HAS FIXED PULLEY WHEELS ON STEPPER MOTORS HOW DO I REMOVE TO FIT DAMPERS
I'm just super hyping myself up for when I get the Ender 3 and just. Holy crap I am so excited. I personally adore the cute and delicious sounds 3D printers make so I probably won't dampen mine unless I can't sleep at all. But tbh the sounds may be super comforting and help me sleep.
I think the most noticeable would not be decibels per say but to combine that with the frequency. I think the stepper motors remove a high requency where the vents are a bit lower (and easier to ignore). And the vents are a steady noise where the steppers are only at play when they move the head which is not moving steady. Interesting test anyhow and nice to see the print and heat don't get affected. There are a couple of mods that you can't print that I might be purchasing thanks to your videos. Keep it up!
Thanks for watching. I agree completely with your summary.
Great video! Just received my Ender 3 for Christmas. Bought a bunch of upgrades prior to receiving it and now it looks like they've changed the design. Stepper motors have a pressed on gear drive in lieu of the set screw version. No way to upgrade to the dampers without some special gear puller to move it. Is there any other forum besides facebook were a newbie can get advice (as I don't have facebook). Some minor issues I'd like to figure out.
I just did the same a few days ago. Just wanted to comment. The high frequency is eliminated and is much better as mine is near my bedroom. But my stepper motors are considerably warmer, maybe not enough to warrant heat sink but warmer than you report for sure. I also (as someone else said) had to print a part to move the x axis end stop as the carriage got in the way slightly, easy fix and I think this is only for the "newer" versions. Overall a very worth while upgrade.
The little changes happening to this printer are making universal mods hard to do.
My steppers get over 50°C now that they have dampeners, sure the 28° ambient temperature is not helping.
Yep...same with mine. Temp on steppers is up for sure.
Ian Lainchbury luckily I have been able to print for over 20h without issues so far. I ordered some heatsinks anyway :-)
thesimbon Just ordered some myself :)
Just an FYI, there must have been a revision in the Ender 3. My Ender 3 that was purchased as a Christmas gift has pullies that are pressed on and don't have set screws. The dampers space the pully too far away and the pully can't be adjusted. The only stepper that can still be dampened is the extruder.
Hey I appreciate all the help. Im totally new to this so your videos are an amazing help. Currently I am having a problem with the stepper dampener for the bed. It seems to block the bed from fully retracting to the rear of the machine. When starting a print and the bed retracts it is a few mm from the switch and the bed shakes then says can't calibrate please reset. Any ideas on how to fix this? I would rather have a nosey machine than to cut it with the dremal. Thank you again u do appreciate the videos. JB
Check out the pinned post, it will help.
I installed the same dampers on my delta printer. Over time the belt tension compressed and unglued the rubber. Not good.
nice advise. I had bought mine from bangood and also a load of matching shorter bolts. nice hint to add that thin bolt to the extruder with a small lock nut. I took the opportunity to upgrade the original extruder on mine from the plastic one to an all metal long arm one that has an option for a filament detector. If updating fans then using 1/2 the rated voltage (so 24V instead of 12V) often runs them quiet but watch the airflow... Use 12V with a 24V fan etc.
Thanks for posting. Interesting idea on the half voltage fan. Maybe a blower style fan would be ideal in this way since they pump so much more air.
I saw this and printed it... so simple. makerware.thingiverse.com/thing:2969593
Thanks for the video! Just a little advice, don't point lasers at your camera. They can wreck cameras quite easily.
this is exactly what I was looking for
Thanks for watching.
Have you been able to measure any dimensional inconsistencies? I'm debating changing my steps/mm, but this is on a delta printer. This isn't the only factor, but with TMC drivers I don't really need the stepper dampers anymore.
As of today 1/17/18, the ender 3 from banggood doesn't have adjustable steppers (the collar that the belt lays on) so you have to get new steppers and pulley collars to use dampers.
I'm not certain how you made the ender 3 extruder damper work without under extrusion. Could you please explain it in more detail? Thank you very much, I've been watching your videos for quite awhile now!
One issue on the E drive is that if your not careful the rubber motor mount shifts the drive pulley as it has the ability to move either at an angle (as I have experienced) or just not as strong in contact during some prints. I ended up removing mine so the drive gear for the filament does not get affected and it made a big difference. The only thing better was to get a better drive gear that had more aggressive teeth and a slightly deeper cut than the original provided part.
I ended up removing E damper after filming this. I agree it's more trouble than it's worth.
If you don't have two additional screws for the X axis dumper, just switch the two long ones with two from the motherboard cover. They fit there perfectly.
In retrospect, do you still think stepper motor dampers are a good way to go? I noticed in later videos that you upgraded MB and added stepper drivers. Did you keep these dampers on or remove them?
where can I find the screw to increase the offset to the engine? the one you see at 4:09
any help with how to best accomplish this with the ender 3 pro. gear is attached differently
Any chance you could make a video on doing this on the 3 Pro?
I used this on my stepper since tmc2208 didn't play well. it's magic tbh :3 but not as amazing as what tmc2208 does on my other steppers. it's some weird wizardry! I also added foam between the screws of my extruder mount!
also you could just use a heatsink if it does it's cheap
Anyone considering this upgrade with a recent Ender 3, check if your printer has the same removable pulleys with set screws on motor shafts as shown in this video. Like others have commented, my new Ender 3 (ordered and received last week) does not have adjustable/removable pulleys on the motors - they're permanently attached, without set screws, I guess unless aggressively cracked off and replaced.
I've been reading this a bit now. I can only assume it must be cheaper for them to make it this way, or maybe users reported issues with the pulleys slipping.
Just got mine direct from Creality via amazon, it has screws in those spots.
Yup same is the case for the Ender 3 Pro. I contacted them asking them why this is what they responded "Actually we do not recommend you to add dampers on the printer. if you add damper on y axis, it will cause pulleys loosening and there will be layer shift on your print. so all printers have been updated in order to stop buyers from adding dampers."
There is a extractor on thingivers that should help : www.thingiverse.com/thing:3230712?fbclid=IwAR1aOBrRrbw2_zrDzPgMuTYSWkQx4OTTH11eU925eJX9xR5oUKabr5YXlqU
hub for what it’s worth, I’ve been using dampers on X and Y from the start, and I am not having any issues with layer shift. I did spend time making sure I had good clearance on the belts and aligning the pulleys for clearance all the way across the travel. I’m running it in my living room and the loudest thing is the fan noise, followed by the Extruder Motor (I didn’t put one on there yet, and might not).
I’m completely new to 3D printing, and just last night printed the all in one micro test, and a benchy, and I can’t believe how good this printer is!
would an enclosure of some sort help with reducing sound? just a big cardboard box with egg cartons stuck to it should do the trick shouldnt it?
Do not buy the dampers from Banggod if you don't have a removable pulley, their holes are too small so they can't be installed :/
Also they look like someone found them in a moist basement
I should've seen this comment before buying
Question, are they all the same, a standard stepper motor dampener, X, Y and Z ? and then the extruder = aka 4x
What kind of reduction in noise can you get if you use both the stepper motor dampers as well as the silent board 1.1.5 from Creality?
Late to the party on this one, but with db, sound is perceived to be twice as loud for every 3db gain. Also, the was a lot of bowden tube movement on those retractions!
Nicely detailed video, but, after a while of using it, do you see any signs of the dampeners getting broken, like a separation of the rubber and the metal? I saw some comments on Amazon about that fact and opted for going Neanderthal and just cut pieces of bike air tubing. It helps but not as much... If no signs are to be observed I'll be ordering some as I'm a fan of that... Thx! Cheers!
I've just inspected my three printers wit them and all are in good shape. If you are concerned, hopefully they are cheap enough to order spares in case.
@@TeachingTech could another option be 3d printing spacers with flexible filament? it would mean you could use all for screw holes and just reprint them when needed
But don't these cause ghosting or anything? doesn't the rubber flex with the torque of the motor stop/starting/ direction changes?
I bought these but found out my Ender 3 I got a week ago don’t have the stepper motors that have the gear piece that can be loosened and adjusted on the axle. Waist of my money now 😢
Would be cool to see the sound spectrum difference
on a corexy this hurts the performance a lot. that's why voron uses a looped belt for the motors that transfer up with a 5mm shaft to the main belts! pretty cool idea but it's a lot of efforts and I can't find the ball bearings /shrug xD
These dampeners don’t work anymore without heavy modification because the motors no longer use grub screws. Really annoying because it should be an easy fix but now it’s much more difficult because of the offset issues and the non adjustable parts.
I got a ender 3 a couple months ago and it’s has the grub screws
Wish I read this before I bought mine 😂 mine are now fixed l, received my ender 3 3 weeks ago
I use these on all my fdm printers I didnt even print with my ender 3 before these were installed also heat sinks on motors an tl smoothers today
Hi. I like too much your videos. I have an Ender 3 and my intention is to silence it as much as possible. In this video you install dampers to reduce noise. I have seen in youtoube, that there is another option to reduce noise installing TL-smoother cards on each individual axis. Also, some people upgrade entirely the mainboard to the version 1.1.5 of creality helping also to reduce the noise. Do you have experience in this? Do you know if is better to install the TL-smoother cards for each axis or replace the mainboard?
Does the new silent board fix the issue and will have no need for dampers?
Thanks for sharing, unfortunately my new ender 3 has screwless friction fit pulleys with short round shafts on the Y & X axis steppers,
I've updated the description to warn of this.
@@TeachingTech thanks for the reply, my new Ender 3 is still pretty quiet compared to my CR10 & Kossel though,
4:12 what do you mean by “this is gonna need to change its offset” and how do you do it?
I know this is old and you might have figured it by now, but for anyone that stumbles across and might find it helpful: he just means that since the motor will be placed further back, the pulley needs to be pushed a bit further from the shaft, that offset. Otherwise you would push the belt towards the v-slot groove.
So just remove the pulley, and reinstall it on the correct location after the dampers are there.
Loving the ender vid, thanks for your effort, mail here does indeed suck :)
Haha and I'm still waiting. Been in contact with the seller and it's confirmed that Auspost are the hold up.
Maybe it will get better / competitive when Amazon brings in their own logistics network :)
Wouldn't they introduce motion between the stepper and the frame? sounds like building in added inaccuracies.
With the stepper on my Y axis motor, my motor collides with the bed, and the bed cannot hit the button/sensor for the homing process, please help
Same
There's remarkably little point installing a heatsink onto the stepper motor! Permitted case temperature is about 80°C (way too hot to touch), internal 130°C. The motor doesn't know whether it's too hot and cannot skip steps due to this, what happens when you overheat the motor, your grease/bearing endurance starts to reduce. At sufficiently high temperatures that i think you can never reach, the insulation of the wiring becomes suspect, and it's possible to have a motor wire, but the actual winding insulation is unlikely to be the cause, instead connector and distributor will show first signs of damage.
The bit that needs cooling is the stepper motor driver IC on the control board, provide an active air path under the stepper ICs or increase airflow there.
Wow, Thanks for sharing
Nice and interesting project :-)
Are waiting for your autoleveling update :-)
I'm sick of waiting for it. Surely the parts will be in the mail soon.
Are the Neoprene bonded cork gasket any good for noise reduction???
That's the printer settings software you used?
This video should be updated with a huge * regarding the Ender 3 Press Fit pulleys and Y-axis collision.
My ender does not have any screws at the end of the motor to adjust the distance of the gear to the pulley
In the ender 3 pro, I cant attach the dampers because the piece that attach the "chain" is fixed, any sugestion?
The new ender 3 pro series does not work with those, dampers 4:39 shows how you adjust the pulley - you cannot do that anymore with the new series.
One thing to mention is that newer generation Ender 3 printers have a press fit gear on the motor that cannot be removed or adjusted, therefore cannot have stepper dampers.
I have a note warning of this in the description now. Very annoying that this cheap and simple mod is no longer accessible.
can u 3d print one in flexible filament?
my drive screws dont have grub screws and im worried about breaking them ive heated the with a blowtorch and tried but no dice
My ender 3 came with pressed on gears instead of grub screw held ones, can I still do this?
tnx for the information, I guess I eventually will buy some. Any difference in all of them, any particular that are especially good (brand)?
Also is it worthwhile to change the fans to Noctua or more silent fans?
Also, come to think of it, is it a good idea to increase fan size and use a reduction adapter for more efficient cooling?
Maybe buy or make super light fans made of carbon fiber (could be a cool project using the 3d printer to make molds) to reduce inertia in the printing head.
Another idea I had is to incase the whole printer within a noise silent box, but with air in- and outtake.
Some very interesting ideas you have. I've seen people encase other CNC machines and dust extractors in old fridges because of the insulation. I've only tested the one type of damper. They generally look identical, they're probably mostly made in the same factory.
Hi, tnx for response! I don't like buying stuff if I don't know anything about the product, I guess I can calm down on getting the best dampeners.
Unfortunately the Amazon link in the description doesn't ship to Australia. Do you have a local link you used?
