This is honestly insane! Its so quiet compared to before. I cant even hear it printing. The noise from spools in the ams are louder than the printing. Good Job Bambu!!
And donāt forget the cracking sound of flexing the build plate to get your prints to release. That is really annoying. 
I thought you were supposed to print those flat side up using supports, no?
Iām in here from the depths of Hell and have been lurking for a short while now watching how this community has grown and matured
One constant has remained true, you and a few other in here have been offering guidance and solved many growing pain issues as with all new cutting edge products
With that said, I waited for you to chime in on the new firmware and its features
I have still been using v 1.5.0 as its a good durable version but lacks certain features that the others have to offer
Some firmware just jives better with some units for whatever reason
But Iām going to try this new firmware and see if I can stop the the nozzle parking mid print due to skipped steps
Now then, back into the shadows I goā¦

Just did the update and the full caliberation
Iām all in now lol
Nice that the motors are almost silent now
When can we expect this feature to make it into the X1E?

I owe you the answer to this. Donāt know.
I used to catch my self matching song lyrics with repetitive sounds from the printer. Those days are gone now. Yeah, my X1ās arenāt silent but the sound reduction is amazing. With the printers in the next room, I sometimes have to check the Device tab on Studio just to see that they are still printing.
Thank you Bambulab!
Noise has been my largest complaint against the X1C and P1S printers, even when always printing in silent-mode. In my opinion, I would rather pay a little more for the printers and have nice silent motor drivers, like the Trinamic drivers.
But behold, here comes a firmware update with āMotor noise calibrationā and this makes night and day difference! I really hope this is possible to implement on the P1S also.
Great job, and thanks again, to the Bambulab-people!

The noise cancellation routine has indeed made my printer much quieter. Seeing the complaints about fan noise leads me to wonder if folks donāt know about the various chamber fan mufflers out there? One of my first prints was a muffler which I lined with self adhesive felt. Itās now almost inaudible. The loudest fan is the heat break fan and it only runs above a certain temperature.
Iāll try to find the version I printed to post a link. If I donāt, feel free to remind me in a couple of days.
It seems to me, in the calibration it works, but while printing it is as loud as before.
This is the muffler I use, it knocks the chamber fan noise way down.
The noise cancellation can only work on the motors, the rest of the mechanicals are going to be just as loud as before. For me, the overall sound levels are much lower, mostly itās fan noise and bearing noise on the rods. I find it to be am improvement.
Hallo zusammen. Ein wenig abseits des Themas, aber wissen Sie, wann es eine neue Firmware fĆ¼r P1S geben wird?
Hello everyone,
Is there any information on when the P1S will get noise canceling? 
It doesnāt have it yet.
Thank you!
Itās being tested now, so Iād expect to see it in the next few weeks.

Has anyone already installed the beta on their P1S? Are there any restrictions or problems? Has anyone been able to test the noise canceling function?
One of the requirements you must agree to for betas (at least the X1C beta, not currently active) is that āyou donāt talk about beta clubā. That is, if someone was in the beta, they arenāt supposed to admit it in public.

I do agree with the fact they must use an accelerometer for this. But I highly doubt itās the vRef they are tuning. Itās probably the same kind of dampening application that RRF uses. During the calibration run you can hear it tries out different dampening algorithms.
My guess is they go through the well known list of the following algorithms:
- MZV
- ZVD
- ZVDD
- ZVDDD
- EI2
- EI3
More on how this works in RRF here:
Strange, I did both the update and calibration, but I have the impression it got worse then the first few days. Maybe I will do a new calibration tomorrow to see if I maybe did something wrong. And if someone has tips on soundprofing the AMS, I would be so appreciative 
That thing is LOUD! The sound is the only thing that makes me miss my Ender 3 Pro S thought; for the rest this machine is a world of difference. All prints are near perfection. Never going back to Ender thats for sure 
I sometimes wonder if the ANC disappears at power cycle? Although Iām sure I would have seen complaints about it if that were the case, so probably not. But I can sometimes swear it gets more quiet when I re-run the calibration.
