I keep my printer in a separate room, and the main thing I hear through the wall is the motor noise, not the fans. The firmware update has DRAMATICALLY reduced this noise for me.
That's great to hear. That's the reason I banished this thing to the garage. I live in a 4plex and didn't want to keep the neighbors up with motor noise through the floor/walls.
I could hear this thing throughout our entire 800sqft unit.
In the garage I can print worry free 24/7 if I want.
Same here, I was surprised at how much quieter it is.
@@3DPrintStuff
Are you having internet in the garage, if not, is the printer worth it without internet?
@@lb8384 Yeah I have internet in the garage. So I can't speak to using it without internet.
With silent speed I couldn’t hear it printing at all in the next room (open doors). I checked a couple times with the app if the printer was still printing. 😅
You really ought to physically separate the sound measuring device (phone in this case) from the object that's producing noise and vibration. Consider using an app that draws a time chart such as Spectroid (although the chart is presented as a waterfall and displays last to 20 seconds or so), so that you may directly compare - the average is somewhat okay as a pointer, but doesn't give you the full picture. Perhaps the new update only affected a specific frequency, but you can only see that from a chart..
This was a quick and dirty setup. I just wanted a quick A/B comparison of before and after the update. I understand the criticism.
I made this video previously that had a better setup: th-cam.com/video/S2lVoW9q830/w-d-xo.html
The app I'm using does draw a chart but it is just out of frame, my bad.
@@3DPrintStuff Of course. I meant it not as much a criticism, but more like a friendly suggestion. :)
A huge difference on my machine. I kept walking in from another room to make sure it was running.
Glad to hear it made a difference, I put mine in the garage cause I could hear it through the entire house (only 800sqft). I'm sure this update helps with transmissions through walls/floors.
This is my experience as well. It is so quiet now I barely hear it running... I love the update so far.
Your video with the microphone surely has a lot more noise than I experience with the upgrade. Now the new P1S needs this upgrade as it is Noisy. Hopefully that upgrade comes. Thanks for the video.
You have a lot of bearing chatter going on with your left and right linear bearings... I recommend you clean and oil your smooth metal rod bearings before the chatter damages the finish on the rods and ball bearings like my first machine did. First thing I did when I received my replacement machine was clean the bearings with alcohol (I actually found metal shavings in the bearings), and oil them with a thick oil like Super Lube 51004.
Thanks for the tip, I'll have to take a look at this. It sounded like this pretty much since the beginning so I just thought that's how this printer sounds from the factory.
I've cleaned and lubed the rods in the past but not the bearings.
@@3DPrintStuffMy second machine was loud just like the first one, but thankfully I applied Super Lube-21030 during the break-in process, and then Super Lube 51004 oil to limit the chatter before any damage happen. The oil seems to work fine as long as I wipe them down and reapply the oil on a regular basis. You might want to inspect the rods on yours though because u could have damage at this point.
Yes, constant grease purge and wipe often keeping things fresh. The German machinist in me, habits.
No that is defiantly not how they are meant to sound from factory. both my printers have no rattles etc. just pure motor/ belt noise. @@3DPrintStuff
@@3DPrintStuff Your printer sounds like sth is lose or it falls apart soon, my P1S sounds WAAAAAAYYY more quiet when its printing this fast.
Like ppl suggested you should maybe maintain your printer :p That is extremly loud and kinda annoying? atleast for me^^
When I ran the calibration, the machine sounded like it was trying to beat itself to death, running full speed over and over into the stops. Some of the collisions sounded like the steppers were skipping belt cogs. It was bad enough that I didn't know whether to risk running the motor calibration again, but I did anyway, because what else was I going to do? It worked "normally" the second time, and I have no idea what happened the first time. The good news is that my printer is okay - and the motors are indeed much quieter.
We have a few machines, and a few days ago I added an A1 mini for smaller jobs. As well as astonishingly good prints that are by far the best I've ever had, as well as high speed, it's essentially silent. While it's calibrating for noise cancelling it toggles between off and on, and the difference is huge. Before this we added a Creality S1, which in comparison is a piece of junk, largely due to terrible software. Bambu are doing so much right, with bed levelling that works, running tasks in parallel taking into account how long steps take rather than one step at a time, excellent input shaping and more. Some glitches with spool getting stuck, but nothing that can't be solved. Seriously great machines.
one hundred percent agreement
Filament sticking? Is this during retraction? I replaced the blade that looked and felt decent. Problem solved.
@@Keith-um1pj i was using a spool of eSun high speed ePLA and the wooden/card spool was twisting on the spool holder and got stuck. I had the AMS too so hooked that up and had no problem after that.
I’ve definitely noticed a difference but I think only because mine is in my office about 5 feet from me at all times since I wfh. I still wear my earbuds while on a zoom call because people hear the fan noise still. Definitely need a new coupled “fan + speed + temperate” silent mode.
Do not clamp your phone to the printer as this will transmit structure-borne noise and irritate the measurement
Quick and dirty setup. My main issue with having this printer indoors was the vibrations/noise that came through the walls/floors, I'm fine with picking up the vibrations directly from the machine to see if that has been affected by this firmware update.
I did a better setup job in your eyes in this previous video: th-cam.com/video/S2lVoW9q830/w-d-xo.html where I had 15" of separation
Good to know. Thanks.
No problem.
Installing it right now@@3DPrintStuff
If you want to hear the difference, print a 100mm circular tube with a wall thickness of a couple of walls.
I believe it causes the noise to be higher frequency. Active noise canceling, in general, removes mid noise, increases high frequency noise, and can't change base. The better the noise canceling, the higher the frequency ends up being(ideally, out of human hearing range), and then the higher frequency noise attenuates naturally.
It doesn't simply change the frequency. It creates a second sound wave that has the same amplitude but opposite polarity to the first sound wave, which makes the sound waves cancel each other out.
To test this properly, you need to put the microphone 1m from the printer on an isolated mount, the take measurement for say 1 minute and do a frequency analysis so that you can get both an average spl noise floor and also an average of the frequency distribution of your noise floor. You then do the same testing with the printer prior to the firmware update and finally you test again after the firmware update.
What I can say is that post update, while the peak spl may in fact be similar, the average is considerably lower and the energy is much better distributed across the frequency range so that there are fewer frequencies that have sufficient energy to stick out and become annoying. Also, subjectively, my office is one room over from my bedroom and the motor noise used to be clearly audible through the wall particularly at night when the noise floor is lower. Since the update, as long as I'm not physically in my office, the motor noise tends to blend into the air filtration system (which produces close to pure pink noise) that I always have running while the 3d printer is active. I find this noise much less objectionable and far easier to ignore than the harsh and aggressive motor noise prior to the update.
hmm mine doesnt sound anything near this without firmare update. To me this sounds like something is broken.
Had to roll mine back, wouldnt print on the textured plate after the update, never got close enough to the bed for the first layer, fine on the other plates, just not textured
Weird, I've only used the cool plate since updating the firmware but usually use the textured PEI, I'll let you know if I have that issue.
I own a x1 carbon since 2 weeks and yesterday I updated the firmware. Now it’s less noisy but the prints started to wrap on the angles and they often come off the plate 🤬🤬🤬
Did you do a full calibration or just the noise one?
Any time you do a firmware update, you should redo a full calibration and make sure you do a bed levelling on the first print after the update. I usually switch the printer off and on again after the update and again after the calibration. If you're still struggling with prints not sticking, try washing the build plate in warm soapy water and make sure you dry it with a lint free cloth or paper towel.
@@TheRodT Full calibration and I tried PLA and PETG. The prints come off the plate. I'm going to open a support ticket. I hope they'll give me the option to downgrade
@@Mangustianoclean yo plate
That printer does not sound normal. There's an awful lot of clacking noise along with it.
It looked like the front door was open and wobbling a lot.
It's his linear bearings on the left and right. This is a problem that no one seems to talk about, but it is something I discovered on my first machine. The linear bearings are basically chattering and vibrating on the metal rods as it moves left to right. My first machine was chattering just like this and it actually wore off the smooth finish on the rod, so I ended up returning it. Bambu offered no support on a ticket that lasted 3 months, so I had to do my own troubleshooting till I found what the problem was, and then discovered the wear marks on the left smooth metal rod. First thing I did when I got my replacement was clean out the bearings with rubbing alcohol, and then lube up the rods and bearings with Super Lube 51004. My replacement hardly has any bearing chatter since I did it from day 1 before any major damage was done.
@d-leb that door is open and the table it sits on isn't the most stable thing in the world but all of the sounds were coming from the printer.
@wrxsubaru02 mentioned it may be my linear rods/bearings that are a bit crunchy/have metal shavings stuck in them.
@mikedixonphoto
This printer has sounded pretty much this way since the start. th-cam.com/video/gJcxC_76g2Q/w-d-xo.htmlsi=Nc2g1DtSlSwf_gL1&t=558
@@wrxsubaru02I've recently bought the printer and i'm going crazy with the sound, can you help a little more on how to do this?
Mine slams against the front right at the beginning of print every time. Did the firmware fix that?
They all do. Bambu uses sensorless homing instead of physical limit switches on the XY.
@@chaosengine3772 thanks
When can we expect this for the P1S?
They have released this for the P1S to beta testers. I don't think there are any restrictions to joining the beta test so you could get it right now if you want. Not sure what the timeline is for the official release.
your printer isnt supposed to sound like that. you could here a clicky noise and like something is loose, you need to adjust the belt tension. That doesnt sound really good. I hd the same problem with my X1C and bambu lab told me to adjust the tension on the belts and calibrate it.
does anyone know if this is coming to the P1S?
It is already released for the P1S: wiki.bambulab.com/en/p1/manual/p1p-firmware-release-history
Did it slow the print?
Nope
no sir
No difference in my opinion still quite loud
Sounds like grid infill to me.
Grid infill on the pre-sliced benchy.
Oups 😂
open door (vibrations) and the phone attached to the printer up close.. meh.
Thanks for the reminder to not buy that noisy box of junk. Wow what a racket.
You don’t buy a sports car for it to be quite
@@joeyschultz7443 lol that's not a sports car. It's a pile of proprietary crap. Build a Voron.
Voron rhymes with so much more on this rhyming thing.
Putting this video out there for people to make their own purchasing decisions. For the speed, ease of use and reliability I still love this thing. I just put it in the garage where I can't hear it. To each their own.
@@3DPrintStuff Your video did just that, keep it up. In the garage, it would freeze up here, and CNC's/Printers don't really like Canadian winters. GRBL and the shapeoko board liked to disconnect the serial connection until things got "warm".
Always have something to complain about.
Better use a 3D pen if this machine is to loud.
Technology is always improving and it takes time
This is still the best printer at this price point. I'm just making an A/B comparison video of before and after the firmware. Some people have mentioned that I may have some issues with my linear rods/bearings that mean that my machine is louder that the average machine, I'll have to look into this.
I live in a 4plex and need to be considerate of the noise being transferred through the floor/walls. I do not want to keep the neighbors awake at night because I selfishly want to keep 3D printing stuff through the night. That's why this thing lives in the garage where I can print 24/7 if I want.
I still love the ease of use, speed and print quality that I've gotten out of this thing.
