So, I added hi-fi isolation spikes to my MK3 because ...

Why the hell not?!!! I'm shocked it hasn't been tried before.

 

I had hoped to install them on the Mini+, but that thing is so horribly unbalanced it just tipped over! I also hoped it would help with ringing by coupling the printer better with the base and solve some resonance issues. Did it work?

Not really. But... the bass has really tightened up,  the mid-band is now clearer, the treble is sweet and the soundstage is something else! Nah!, it's still a monster producing some of the most horrible, nerve-shattering noises ever produced by a machine. Printing diagonals sounds like Cthulhu getting it on with a clam, from the clams point of view. And the ringing, bless it, is as bad as ever.

I'm taking this failed experiment on the chin because someone had to sate my curiosity. The cat is well and truly dead. I'm at the end of my tether with nothing but a warped sense of humour left. Have pity or have mercy. The choice is yours.

Yes, but did you notice that it is High Fidelity horrible Ear-Shattering noises?   It took a team of Czech audio engineers months of study and experimentation to get the balance between Cthulhu and Clam just perfect and that's not even considering the time and effort spent to achieve the signature Ringing, which microscopically encodes each printer's Serial Number and Revision into every print.

This is what you need...

Printer (with stock feet)...paving slab...foam. Made a huge difference to the noise levels.

Basically the more mass you can put under the printer the better.

Cheers,

Tim

Thanks, I'm going to Wickes tomorrow. I just don't think it should be making that noise at all. It's only on diagonals, bottom left to top right, so I think it might be the single bearing on the right being skewed by the motion of both axes.

I loved the humour 🙂

Not surprised at the result, I thought the function of those spikes was to couple the speaker mass to the ground. Or in this case, the wooden cabinet/shelf the printer is resting on. Which causes resonance in the shelf.

I went the other way- sorbothane isolation feet. Noise went way down, from 'really obnoxious' to 'moderately quiet'. I sent some sorbothane to a friend with the same printer, same results.

It's in a 3-tier IKEA Platsa, which I would have thought had a lot of combined mass. It's a terribly anxiety-inducing noise, like finger nails on a blackboard. I found some washing machine anti-vibration pads on Amazon that I might try under a slab but I really dislike buying stuff from Amazon. For the sake of sanity though, I'll try anything. How did you mount the feet?

This sounds familiar to me 😀

One source of really bad noises can be the PCB vibrating inside the LCD-housing.

As a test, unscrew the 4 screws that attach the LCD-housing to the frame and lay it temporarily on a piece of foam or cloth an do a test print. 

There should be no mechanical connection to the printer frame any more, except for the wires of course... 😀 

What is your result?

I have been toying with the idea but I've come across some negative comments. I've got some spare PETG though so I may give it a whizz.

Ha ha ha, I knew it. I only listen to the squeals through the night because I know that they are the highest fidelity possible. 🤣 🤣

I'd have expected anything from Ikea to be really bad for amplifying resonance- there stuff is made of chipboard which is very lightweight and full of cavities. Just rapping your knuckles on it should give a good indication- loud hollow sound bad, deep thudding noise good.

@Helmuth. You are right in one respect but it depends a lot on the source of the noise. Some materials reduce internal resonance because they have cavities or varying densities or grain structure. I once came across a duplex steel that sounded dead when struck with a tuning hammer. A plain steel rang like a typical tuning fork. I think the box acts like a resonance chamber for the airborne noises created by the various moving parts. Adding the spikes causes more movement of the box because it is now coupled more strongly, making it act like a speaker as well. The lightweight construction, as you point out due to the materials, is what made that worse.

I made another post that shows what I did, following the lead of others, where I used high density foam and a concrete slab underneath the printer. I have 4 of these now in a monolith of IKEA Platsa cabinets that has made a massive difference. I can barely hear a thing now, even with the doors open. I do wonder though, what the effect would be to add the spikes now! Unfortunately, I don't have enough spare height in the box to accommodate the spikes.

I very much enjoyed this post. I'd be lying if I hadn't considered using speaker spikes myself.

If you want to try it, I designed some pads to accomodate Sorbothane hemispheres. Sorbothane works to isolate vibrations. I've personally found it works very well in quieting a printer using them alone.

RE: So, I added hi-fi isolation spikes to my MK3 because ...

You may see better results if you coupled the printer to a inertia base and then the spikes.  Most speaker stands I've seen the spikes on are weighted with the speaker coupled to the stand.  I think the rationale behind the spikes is to prevent vibrations to transfer to outside of the printer 'system.'  The foams and dampeners are to reduce the impact of movement within the system, increase machine life and quality of print, as well as lower noise.  

I would suggest skipping to printer - sorbothane 1 - inertia base - sorbothane 2 - seismic mass - decouplers.

 

1 - first level should be calculated for min max of printer mass plus dynamic forces

2 second level of dampening takes 1 and sums the inertia base.  

 

People have not reported increased quality, but I wonder if you could increase speed and maintain quality.  Tests to be conducted...

RE: So, I added hi-fi isolation spikes to my MK3 because ...

yeah, spikes,

so that couples the frame to some mass,  Great start,

but the (christ its annoying)  X  beam has its own separate freq, which sounds somehow simutaneously,  like audio from hunt for red october, and the abyyss ,

its already high freq, so the home depot supplied blanket fixes are out

jeez, like a waterboarded wookie,  I have the shipping box  serving LAK style, still certain speeds and motions.

 

its like the cabin drone you can get cutting the resonator out of a turbo'd car, and find that along with faster, it now makes a godawful resonant hum at 73.6 mph
