Stepper Motor Vibration Dampers on Anycubic Kossel Linear (Before and After)

Fitting vibration dampers to reduce stepper motor noise on an Anycubic Kossel Linear 3D printer. Surprisingly effective!
These are the ones I used:

It looks like the sound meter level is limiting at 60dB, so the steppers are much louder than they appear.

Amazing how so many people think this needs to be a 10 minute video. Great job thanks

Thanks!

I was second guessingy if those were $11 worth and your video just settled it. Thanks.

These do work awesome I've used them but opted out because you can't tension the belts properly, as long as you print at slower speeds that's not a problem

James - I have a similar setup with vibration dampers on each of my 3x mini kossel stepper motors.
Have you had any issues with end effector mechanical resonances?
It appears during rafts (not sure why it's only rafts) my effector stutters quite harshly and I have narrowed it down to mechanical resonance (serial buffer isn't stressed during straight raft moves, bed is flat and leveled, extruder is able to keep up otherwise) and given these mounts torsionally flex quite a bit I'm thinking they are hitting a speed that it doesn't like.
My next move is to significantly increase raft print speed to see if I can get up above the resonant frequency.

i was wondering how to remove the stepper motors? can you shim the belt off? the phillips screws from the inside? remove the pully ?

[@jamesward408]

Hi Gianna, I loosened the belts at the carriages, removed the stepper motor screws with long ball ended hex/Allen keys - it's really very difficult to access though, and the screw heads are easily damaged. Difficult but not impossible!

Hi! I would love to know what have you done with the lower part of the printer. Did you use some kind of rubber bumper feet? Maybe accomodate the power supply there? What about extra ventilarion? ^^ Thanks in advanced

[@jamesward408]

Hi! Yes, I used rubber feet (self adhesive) and made a base plate from MDF to mount a larger power supply. I designed some 3D printed stands to raise the printer, and cut aluminium side panels. All the details and 3D models are available here: www.thingiverse.com/thing:2024677
Hope this helps?

[@WillY1905]

That helps a lot, thanks for sharing and happy printing

[@jamesward408]

No problem! Happy printing :-)

Try solving the vibration issue by removing the cause of vibration which is electrical noise. See this th-cam.com/video/lPouqnIO-AE/w-d-xo.html or this th-cam.com/video/zbE73bRzxvI/w-d-xo.html

Thanks. I've heard of those drivers, and it does seem effective (although I've not tried). However, having fitted dampers, the only real noise I hear is from the fans, and my next plan is to find some quieter fans to replace those!
