Could you recommend this for a direct drive setup?

I'm using it with a direct drive setup. I'm happy with the results. it's very easy to reverse if you're not happy

Ok I may try yours out, I have another damper adapter on mine now but I’m getting some weird vibration rattle I can’t trace down and I’m gonna replace everything if need be

I think I am having issues with this, I am 90% sure I installed everything correctly and it seems to have worked somewhat, but the x-axis is still insanely loud compared to my properly dampened y axis, but it is still quieter than the Z-axis. Is there anything I should double-check? the instructions where a little hard to follow, I would appreciate more pictures from different angles during the installation.

Maybe try loosening sine if the screws

You should make sure the belt is not too tight. It's possible that the belt is causing the motor to still touch the metal plate. Also make sure the motor is centered in the bracket. There should be a small gap around the large inner hole the stepper motor fits into.

Tried both and it is working like a charm, thanks a ton!

Does this work for Ender 3 Pro? I tried the Y-Axis mount and wouldn't work. Curious if this will :) Also will the Z-Axis work aswell?

both the z-axis and x-axis adapters work for the ender 3 pro.

where do you put your heatsink?

I was wondering if this works with the Ender 3 Pro. TY.

Thanks for the design. I had a few problems with it, so I decided to print another design instead (which was a pain to install). The spacers were too long for the dampener, so I took them off. The x limit switch was only held by the hole in the frame, therefore the banging on the limit switch loosened the mount (which I later fixed with firmware edits). The biggest issue was the stepper hitting the metal plate when torqued one direction. I am guessing if the dampener mount was printed with slight slant this issue would go away.

I might try to make a remix, since I like this design way better than replacing the metal plate.

Hi. Congrats for your design. Do you use some kind of screws on the right side, i mean the original long 4 screws?

There are 2 options for mounting the end stop switch... If you choose to leave it attached to the original cover, you would print out 4 pegs and mount the covers with those. Two of the original four mount screws would be used to mount the stepper motor from behind, the other two remain unused. I hope that answers what you're asking.

Hm - maybe I'm missing something here, but I don't really get what advantage this offers over the common way to install the damper in the front - without any additional parts. Can't get easier than that (no additional parts needed but the damper itself), the lever of pull for the belt is better when installed on the front of the stepper motor. This solution can't produce less jitter than the normal way (instead of being fixed to the metal frame itself the stepper is fixed to printed plastic). I don't want to play negative nancy, but this looks to me like overengineering with no real benefits. The standard way to install a damper does not need any extra parts and is proven to be silent & stable. Heat sinks can be used with no other parts in the way.

Maybe you can explain (again) what advantages this offers over a standard damper installation?

If the pulleys on your stepper motors have mounting screws, then damper mods are not required. However, most Ender 3 printers have press fit pulleys. therefor, Installing the damper on the front of the stepper motor moves the drive pulley 6mm out of alignment. There are only 2 ways to counter this, either replace the large structural metal plate on the front of the carriage, or what I have done here, which is to add a small 3D printed plate on the back which maintains all the structural components of the printer.

Ah I see, then I have an older Version of the printer, because I can remove the pulleys, they are secured with two inbus-screws on the axis of the stepper motors and can be moved along the axis and be fixated again. With press-fit pulleys ist makes sense of course to fix the damper on the rear end. I was only wondering, because i just added dampers on my machine a couple of days ago, and it was a 5 min. job on the x and y axis without additional parts - very easily done and with impressive results cutting down the noise of the machine. Z and extruder are not really worth it in my opinion, as you hear the z-axis only on homing in and after finishing the print, and with the extruder there is also little noise and I'm afraid that the higher torque would twist the stepper a bit and make the filament feed less accurate with a damper installed. But x and y-dampening are kind of a must if you keep your Printer in your living area in the house.

Too bad, that creality choses cheaper solutions that can not be modded properly any more - the easy and open "hackability" was one of the reasons I got the printer in the first place.

So, thank you for providing this solution for anybody with a press-fit pulley ender 3!

if you add Auto leveling to your printer you will find that a z axis damper is very useful but otherwise I would agree it's not necessary. However, you should also look into adding squash ball feet to the printer as they reduce sound significantly as well.

How often do i have to print the parts?

I have never replaced any of my printed parts due to failure of any kind, if that's what your asking.

No, I meant: Do I need for example the spacer/cover_peg multiple times? Im sorry, english isn't my first language.

Sorry for my misunderstanding. You need 2 spacers, 4 cover pegs and 1 stepper adapter. If you don't want to use the cover anymore, you can replace the pegs with one end stop. happy printing!

I do like your Y axis adaptor a lot because it works like a dream! :) I am afraid I can't say the same about the X axis one. This design gives me no space to slap a heatsink on the stepper's back side to keep the it as cool as possible. The steppe was going so hot I couldn't hold my hand on it so I had to find another solution.

Still, thanks so much for your time and for sharing your ideas! It's greatly appreciated :)

It's too bad your having heat issues. I'm wondering if there might be another issue causing your stepper motor to get too hot. Mine are just a tad warm to the touch after hours of nonstop use without a heatsink...
Alternatively, I just added an updated design that works with a heatink. Let me know if you have any issues with it.

I think it's just how my steppers work. They were fine when attached directly to the printer's frame but they all are now a lot hotter so they all need some sort of cooling since they're detached from the frame and the dampers don't provide any way to dissipate the heat at all.

Thanks for the design update! I'm sure people will appreciate it. I'll keep to the mod I found, kinda lazy to update the firmware again lol

Is it me or did you put the damper on the back side of the motor?? If so, I am not sure that will really help. The point is to separate the metal brackets.

It is on the back. Check the pictures, you will see it is no longer attached to the frame from the front.

Ah, OK I get it now. :)

Just done and installed ;) now i will try it for make the Y-axis adapter! Thumb up for the easily design and installation!

I was just about to try this set up. Can you provide any feedback on functionality? Print quality?

it's work fine! no more annoying noises from your stepper motors!!
I done some printing test and quality still look great as usual! :D

I have not experienced any reduction in print quality, it just made things quieter :)
