Noisy printer

[Mango Chutny]

Hi folks.

I have had increasing noise from my Sovol SV06.

I would like to offer you a nugget of information before you start getting the spanners out.

Put your printer on jelly feet.

It may simply be that the rubber feet, which have a large contact area on a Sovol SV06, have settled over time and are transmitting vibration to the table.

My printer is now quiet as new.

I hope this is information nugget is useful and saves you from needlesly changing parts.

ps. If you are a nutter and have to print at 1000mph things could get quite wibbly wobbly on jelly feet. Going completely in the other direction could be useful. I have fixed vibration problems by bolting small machines to a paving slab.

Hello and welcome!

You are a laugh , an 'e' left out of your forum name and added to the thread title instead! Deliberate? But I can't stand spelling mistakes in thread titles so I've corrected that one.

Jelly feet?

The last thing a 3D printer needs is any kind of vibration or wobble, and I can't imagine any respectable printer being on feet at all. Noise is a by-product of FDM printing, and if acoustic coupling to a table or shelf is making that noise worse then the mass of the support needs increasing (as you say, eg with a paving slab). What you don't want is an interface layer which reduces noise by allowing the printer to move.

CrazyIvan, Not everyon is going to be able to use a very heavy object to place under their priner.
And an imperceptible drop in print quality for a big reduction in noise is a worthwhile compromise for some.

Sorry, I don't agree. If the print is tall and thin, or contains tall and thin elements (such as legs), wobble can be sufficient to cause a print to fail – that's not an "imperceptible drop in print quality".

This print failed because wobble caused the nozzle to knock into the leg and displace it (I terminated the print when I spotted it):



...but wobble is unavoidable on the Tina2 due to the Y axis motion being movement of the build plate (and is why my next printer will have the nozzle moving in X and Y and the build plate only moving in Z, if at all).

If you must damp the acoustic coupling between the printer and the table/shelf/whatever, and don't want to go for the preferred option of a heavy mass, use a thick cloth (eg a folded tea towel) rather than rubber feet.
