Bambulab P1S Noise cancellation

[@vhateg]

Funnily enough, Bambu decided to skip using stepper drivers and control the steppers directly from the MCU, because it was cheaper. But, this has allowed them to do stuff like this, since everything is software defined. It played out nicely in the end.

[@StokesSimGears]

Have you by any chance noticed any changes in print quality? I'm curious if this helps with the infamous VFA issue or vertical banding at lower print speeds (

[@Kenprints]

i printed a benchy and a calibration cube last night on the p1s after it completed its update and calibration and have to say both looked flawless or at least less flawed than before if that makes sense - they had really smooth sides and sharp corners - i cant say the update caused any issues anyway

[@martinbilodeau5011]

I just noticed a new icon option, under the light icon, for AMS does it permit to configure filament just like in X1C ??

[@Kenprints]

No i dont think so its to say if theres an ams connected or not il check for you later

[@Kenprints]

So i just checked and the AMS option on the printer only allows you to reset the AMS ID Other options available on the printers screen now include "Accessories" which allows you to select the nozzle type installed and an option to select whether or not you have an official enclosure kit installed or not

Is it possible to change the pannels to sound absorbing pannels? :D

[@Kenprints]

Yea im noticing vibrations coming from the chamber fan that attaches to the side of the printer im going to see can i improve that at some stage

[@hippopotamus86]

You can, but it's really pointless. Others have done it, spent time and money and had hardly any change.

[@YaNeK92]

I'm really confused now because everybody's been telling me to get the A1 or the mini because of how quiet they are, if I want to have the printer on my main desk where i work/study/game the P1S would sound like a Boeing 737 taking off. Is it necessary to have the fans on at all or just when printing with certain types of filament? I do prefer the P1S' style and enclosure with the sleek AMS, however the noise was a real deal breaker for me. Thanks for your help :)

[@Kenprints]

@@YaNeK92 if noise is a deal breaker get the a1 or mini

[@Tome4kkkk]

Can you run it with PLA continuously with the top lid closed? Is it the most silent then? I assume you have to run the chamber fan then.

[@Kenprints]

i change no settings and yes run it with all closed if printing pla i have added an exhaust muffler to the chamber fan its quite quiet when its fitted

[@Tome4kkkk]

@@Kenprints Thanks! I'm asking because I may buy P1S for pennies more than the A1 but I'm really worried about the noise levels.

[@Kenprints]

@Tome4kkkk i sold my first 3 p1s models after 1 year and bought 3 more of the same they really are a great machine

[@Tome4kkkk]

@@Kenprints What was the then rationale to sell them? And do resell buyers have no problems with Bambu Lab support/warranty in case of a problem with a resold printer that is less than 12 months old?

[@Kenprints]

@Tome4kkkk similar to someone trading in a car after 12 months of ownership - machines are still in great useable condition but have mainly paid for themselves - i upgrade to brand new ones and someone gets a good deal on a used one - warranties would all be up on the 3 that were sold at this stage or very close i would say - also if anyone that purchased one had any issues i would assist if needed - incl my previous sale which was the a1 and the following day they announced the cable bed issue - i offered them their money back which they declined and instead i put the claim through for their replacement bed and gave them the 120 voucher also so they did well 😂

[@MrKlawUK]

whats the best balance of noise - eg if you open the top/door can you reduce chamber fan speeds or does the open door mean more noise escapes than it saves? The fans seem way louder than the A1 but there are more of them so maybe makes sense.

[@Kenprints]

oddly since the latest update the fan doesnt run much and they are generally quiet machines now have to say i love them - all 3 running at same time in my office isnt an issue

[@Rhotgas]

I don't understand why they don't put regular, quiet fans in it

[@evidentloss]

I am part of the beta program, but it doesn't show an update available in the "Handy" app. Did you have to do something special to receive the update?

[@Kenprints]

No nothing required really apart from to check the app occasionally to see if the update is available maybe restart your machine and check for update also

[@evidentloss]

@@Kenprints Currently printing, but will give it a try later. Thank you.

[@Kenprints]

@evidentloss no problem Good news is there are no negative issues to report so far

[@ChristopherFortin]

are quieter fans available, I heard something about that on the X1 carbon

[@Kenprints]

yes noctua fans can be installed and are wuieter but appear to flow less air so may as well just turn your own fans down to a lower output

[@ChristopherFortin]

@@Kenprints sorry to bother, aren't the X1 fans better quieter, can you put that in your P1S as an upgrade .... or better just to save and wait to go X1 class. I have the A1-mini but can't decide where to go next.

[@Kenprints]

@ChristopherFortin not sure whether they would be any quieter or even compatible if they were i suggest a p1s combo if you can stretch to it they are phenomenal for the price

[@ChristopherFortin]

@@Kenprints that's what I'm looking at, but maybe went a little overboard on my filament purchases last month !

[@ChristopherFortin]

P1S incoming

[@SchroediFPV]

How do you get the firmware to test?

[@Kenprints]

In the handy app select "me" down the bottom of the screen and go to settings there will be a slider to allow you to opt in to BETA firmware program- turn this on and you will have to then wait until they accept your request takes less than 5 days and then and in the top right hand corner of the screen there should be 3 horizontal lines tap on these and select firmware version it should give you an option to update to the beta firmware

[@SchroediFPV]

@@Kenprints OK, thank you very much

[@Kenprints]

No problem

[@vandal968]

I joined the beta program a few weeks ago, still haven't gotten the option to upgrade 😪

[@Kenprints]

@vandal968 thats odd maybe they are not pushing it out to everyone that asks ?

[@benryfpv]

it it worth joining the beta to get this firmware or should i just wait?

[@Kenprints]

Totally up to yourself i was a bit hessitant at first as i was afraid if there were issues it couldnt be rolled back but you can still roll back to older version on p1s and p1p at the time of writing this

[@madness3D_]

@burmanatorx7725 in my opinion its so extremely worth it. I thought my printer wasn't running as it is now so quiet. I have not noticed any negative sides yet.

[@Kenprints]

same as that - no issues to report after a week of usage

[@Potatorouter]

Is that feature also on the P1P?

[@Kenprints]

Yes 2 of my 3 machines were p1ps that have been converted to p1s with the official bambu kit and oddly in the settings now it asks if you have upgraded to the official bambu enclosure kit

[@willieow3298]

So, it allows you to turn off parts cooling fan. Does that affect the quality of the print?

[@Kenprints]

you always could turn off parts cooling fan as far as I'm aware this just cancels out the noise of the print head moving around which has decreased the noise a lot - I would guess the P1P model gains best from this as it only has the parts cooling fan anyway whereas the P1S has the AUX fan and chamber fan and the cooling fan on the main board also

[@patrick5592]

@@Kenprints Does that affect the quality of the print?

[@Kenprints]

@patrick5592 its not the fan that the noise cancellation is working on its the other motors driving the toolhead but no the noise cancellation does not affect print quality

[@D4RKFiB3R]

Does it affect the speed of prints? Thanks.

[@Kenprints]

no negative impact whatsoever

[@D4RKFiB3R]

@@Kenprints Thanks

[@Bastyyyyyy]

im excited for it, i mostly hear the printing noise, since the fan noise gets competly canceld out by closing the door in the room, but the printer i hear even 2 rooms apart. Hope in siltent mode and new update i dont hear it :) The update will come sooner then expected!

[@Kenprints]

Yes i dont mind the fan noise so much i get used to it but the motor noise is (was) annoying 😁

[@carsonhunt4642]

Is it too noisy to sleep with if it’s next to your bedroom ? Obv seems too loud to keep in your r room. But one wall across? Otherwise I’m thinking outside garage but it’s not temp controlled so could cause bad prints

[@Kenprints]

@carsonhunt4642 its roughly 45db so i guess yes if u were trying to sleep it wouldnt be great but its fine if its in your office etc while you worked

[@Bastyyyyyy]

@@carsonhunt4642 I have it across the room. And I don't hear anything. Just a thin drywall with some insulation. It's apparently enough to not hear it.

[@TheRIkkyP]

Your idea of “crazy quiet” and mine are clearly VERY different. Maybe quiter than it was but still in no way quiet.

[@Kenprints]

In comparison to what it was its virtually silent - the mic on the iphone picks up the low noise and makes it sound louder than in reality

[@HextorBane]

Quiet and FDM printing are two concepts very well separated. If you want a completely quiet FDM printer, you have to keep it off and use a resin printer instead.
