Mine is sitting on a 90 pound concrete paver but it is still so much louder than the MK3/MK4! Please give us this 'feature'.
RE: We need a motor noise cancellation update like the Bambu got today.
It’s made a real Difference to my X1C. I’m not sure the XL hardware could support this? Or the bods are capable of adding it to the firmware.
RE:
Bambulab is using their own custom stepper motor drivers. I don't know what Prusa is actually using but their work on motor noise cancelleation might depend not only on Firmware but also on hardware. Key people from Bambulab are coming from DJI so they seem to have real expretise on motor control, hardware and software.
I don't know all that much about the details of stepper drivers so it would be cool if someone with more expertise can comment if that noise cancellation is potentially doable outside of Bambulab hardware setups.
PS: A great way to reduce noise are enclosures. The XL would need good and somewhat affordable off the shelf enclosure options, from Prusa or elsewhere. Maybe they exist already but that would go a long way already.

Not an expert… but imo…
Stepper Motor noise typically is a function of current settings. Lower current, less noise, less torque. There’s no “noise cancellation “ as in generating a cancelling freq of sound. Current settings are kinda also important for the microstepping which makes smoother curves. Current levels that are not spot on can also make small vibrations which translates to the print (that’s what killed the old Type A machines). Note that on a toolchange the X/y motors are kinda high torquing.
I’m not too sure that it’s motor current or the steppers that’s making the XL loud. Seems to me the noise is the fans and it is what it is. Ya got as many as ten of them going at once for the extruders, plus three from the PSs.
RE: We need a motor noise cancellation update like the Bambu got today.
It was my understanding that the Bambulab approach is a bit more sophisticated than that but maybe I just have no clue, which I am ready to admit when it comes to stepper motors. It is just that I think that the Bambulab CEO said in the CNC Kitchen interview that the solution is partly based on their custom stepper motor driver, so not a pure firmware solution.

RE: We need a motor noise cancellation update like the Bambu got today.
Well if it's in their driver it is a FW solution. Regardless, I really doubt they actually make a cancelling sound as in noise cancelling headphones. Just my opinion, I don't have a Bambu (not yet), but it would not make biz sense to go to that much trouble. The Bambu machines like all the other single extruder machines, can go low current. Smaller motors need lower current, larger motors need more. The steppers in the XL for X/Y are larger than medium sized lamination stacks and as such are probably a higher motor current. Again though I think there's way way more sound coming from the fans then the steppers!

The fan(s) are not louder on mine.
RE: We need a motor noise cancellation update like the Bambu got today.
Correct me if I'm wrong but noise cancellation requires a microphone to get feedback about the noise produced as it adjusts things motor wise. That would imply that the hardware has a microphone available to perform that task.
I don't believe the XL has a microphone built in. Does make me wonder if the Bambu printers that support this do ?
RE: We need a motor noise cancellation update like the Bambu got today.
So let me see if I get this straight...
There are people here who care more about how loud the XL is Vs things related to getting optimal prints such as a primetower that supports real multiple materials?
Really?
IMO, I would rather Prusa puts its very finite resources to polishing the FW and PrusaSlicer. If noise is a problem for you then it would be a good idea to NOT have the machine in a place within your work or living environment:

Number 1. Let me see if I can set you straight about me. When did I say I cared more about how loud the XL is versus getting optimal prints or above anything else for that matter?
Not once, not ever.
2. They have a large staff. They can/do more things than one. When have you ever seen them release an update that addressed just one thing? Never. LOL
3. Good luck with that 'Health concern study' and how it many current and future 3d printer owners will take heed and move their printers outside their 'work' or 'living' environment.
And finally, if you don't have something useful to contribute to a thread/discussion, don't post.
RE:
I don’t think they actually have all that large a staff. Certainly not for Sw and fw.
And
I can argue that posting a “Bambu did this and I want you to do it too” post is also not of much value. If Bambu’s updates are so valued by you then perhaps you should go buy one!
and if I want to post I will do so!
RE: We need a motor noise cancellation update like the Bambu got today.
I went and looked real careful at the Bambu announcement and I watched the vid where they showed a tester and compared noise levels.
Bambu (as well as Prusa) gets real loose about their marketing way of showing off “features”. As I recall when Bambu did their first KS campaign for the x1 they hinted that their fancy LiDAR approach would also measure extrusion width and then it would adjust extrusion on the fly the way Markforged does it. Well that was baloney. I would bet the “noise cncellation” that they are showing is doing something with the current to the X and y steppers. Decreasing or massaging current has advantages and disadvantages. The advantages include lowered sound as well as possibly a cleaner movement, but the disadvantages are a way higher chance for missed steps as well as lowered precision. As I said above, the XLs steppers are relatively larger motors and as such will require higher current levels. IMO I’ll take the higher noise levels over loss of control and missed steps any day.
RE: We need a motor noise cancellation update like the Bambu got today.
You are just silly at this point but your posts speak for themselves. I wanted it to be quieter before the Bambu announcement. With their announcement though it shows it may be possible.

I bought this printer to be able to print large print that could take days. Yet the thing is so loud that I cannot run that printer anywhere in my house at night if I want to sleep and that's with it being in a closet with an heavy concrete pad and everything. So yeah personally I would put some resources on getting that thing quieter. Obviously that's not a problem for everyone.
Are you really surprised that people have different priority for how to improve this thing..
RE: We need a motor noise cancellation update like the Bambu got today.
Again I disagree. You say the Bambu posting shows it's possible. It shows it's possible for the Bambu machine. It does NOT show it's possible or appropriate for the Prusa XL as I am attempting to explain to you. You choose to ignore the facts about what Bambu is actually doing. The motors are different. Seems to me your requirement for lower sound levels makes the Bambu a better machine for your needs.
I would vote for Prusa to not bother with this request at the expense of other much more important things.

Get a bigger house. 😄

The cynic in me says the Bambu doesn't have a microphone either. I'm not saying the "noise-cancellation" animation on the Bambu is fake. But I'm not not saying it either. A cynical explanation is they're running the drivers with currents and speeds known to cause noise, then displaying a fixed animation while reducing currents and speeds back to known good values, making it look like something magical has happened. Whereas their competitors ship with known good values as default and avoid the dog-and-pony show. There's a bit too much P.T. Barnum in the Bambu printers for my taste.
RE: We need a motor noise cancellation update like the Bambu got today.
There is a project going on from the 602 issue investigation era, which will be interesting to you. But it is not just reducing noise. Testing phase has begun.
RE: We need a motor noise cancellation update like the Bambu got today.
Ok… I went to GitHub. Read the whole saga from 5 years ago. Looked to me like a motor current issue not unlike what killed Type A Systems. I recall hearing about it. Obviously Ive never owned a Prusa printer before so I never had this issue even though I have three extruder feeders from Bondtech…
Regardless… Jo seems to be hinting that there may be things that can be done with the current that might mitigate the sound level. I guess we will see.

It's coming "soon" it seems 🙂
