Building a home made enclosure to damp the dB
Hi I just did the upgrade from mk3s to the mk4s and I live in small apartment and the noise its not super bad but I would like to lower some dB, I did order a core one kit and it has an enclosure but I think the dB are very much the same if not worst, this only comes from what I made out of the coments.
My question is I have some plywood around home and some noise foam so I was thinking to make a large rectangle cube to enclose the 2 machines, for the MK4s making a hole above to stick the filament out of a sunlu dryer and for the core one just leaving the right space.
In the mk4s Im only printing PLA and PETG so Im not sure if it may be too hot in there and should I make a vent on the top or add some computer fans maybe 1 to make the flow of air inside and another one as exit? not really sure on how to procede on all of this.
And the PSU is it really that bad to have it inside? Is there any manual on hot to detach it as the cables are very short or they look to me.
Im really lost on this but my biggest problem is the noise specially at night for those 3 or 4 days prints I can go nuts.
Thanks a lot
Are you using stealth mode?
Try slowing down the printer during the quiet hours, it will add some time but reduce accelerations.
Cheerio,

Is there any way to schedule those slow downs from the prusa connect? I was thinking about it that schedule may be a a good option
Interesting thought - you could certainly insert it into the gcode with a post processing script but as the sound would only bother you if you were present dialling it in from the LCD is probably more practical.
Cheerio,

And about the flow of air is it a good Idea to add a fan introducing air inside all the time like a pc build?

I was always satisfied by the noise floor of the MK4S, much much better than a Bambulab. My concern was the toxic fume of the filament.
I have issues also with PLA and PETG, so I decided to build an enclosure based on the PRUSA IKEA Lack. The air is extracted by tube and a fan, and expelled outside the window through a hole in the window glass that I already had. In this way, the fumes can't exit from the large space between the Lack and the plexiglas since the inside is under pressured, and new fresh air is introduced from that spaces, avoiding also to have too much heat on the power supply and motherboard box that I did not removed. It is not designed to be a heating chamber.
I have just finished to assemble it. 😀
If you want only to damp the noise, then you can start from the IKEA Lack box but modding it by using plywood with some thin adesive foam to even damp the sound.
