RE: We need a motor noise cancellation update like the Bambu got today.
I was also told on support chat yesterday that a resonance fix is coming soon in a new firmware alpha.
RE: We need a motor noise cancellation update like the Bambu got today.
The term alpha version in sw dev is typically referring to test versions that shouldn’t go to actual users yet. Beta usually refers to sw that is not final but is tested by actual users with real use cases. Perhaps Prusa is yet again inventing their own words for things, but regardless I won’t waste my time or my resources on alpha versions, particularly for something as relatively unimportant as how loud the machine is. Frankly I’m disappointed that they spend valuable dev time on a non-critical to operations thing like “noise cancellation” when there are so many other things that need attention.
RE: We need a motor noise cancellation update like the Bambu got today.
I have an XL and there is some weird resonance that happens when doing Y moves. The general noise of the steppers is not bad but at certain speeds a direct y axis move is extremely loud, easily 20x louder then any other movement. It's worse when moving towards the extruders rather than away from them.
Mine is in the basement of my house and I can hear it loud and clear when printing at night. Printing at night can't be avoided with such a large build volume as many of my prints are 30 hours plus. Altering print speeds can help some, but it's still there.
I know it's not a problem with the axis itself because diagonal movements are not loud, only straight Y axis moves.
They do need to do something about it. I'm not sure if it's a software fix, if it is then great. I'm fine with a mechanical fix too if needed.

Good cause that's exactly what should do with an alpha or beta firmware. You don't need what it fix.. you don't install it and wait for stable. In my case I will be installing that thing day one cause I'm just about to build that damn printer a shed in the backyard because of how abnormally loud it is.
Also alpha has never meant inhouse only. It means that it's either incomplete and or unstable. A lot of stuff is released in alpha and it's in no way bad of Prusa to release stuff that way so long as it's made clear it's an alpha and should only be used if you really need that fix or want to test it a your own risk.
You just sound so salty about them prioritizing your particular need and it's sad. People have different problems with the printer and different priorities about what should be fixed first and it's nice that they fix stuff for everyone.
RE:
I found that dampening the panels helps reduce the resonance significantly. That 20x is reduced to 2x.
I made seals for the panel edges to keep the airflow down and in the process, found serendipitously that it quieted the noise significantly.

RE: We need a motor noise cancellation update like the Bambu got today.
Actually, my XL doesn’t seem to have a sound issue at all! Certainly nothing like the posts here. Perhaps this is not a systemic problem and instead it may be an issue with the specific stepper motors themselves. As such Prusa may be trying to solve a problem in firmware (thanks to the complaints about Bambu getting noise cancellation) which may actually be a QA problem with the motors.

Which ones in particular? The ones that slide into the extrusion on the inside of the panels?
RE: We need a motor noise cancellation update like the Bambu got today.
All. The bottom, sides, and back. That includes the handles, above the handles, inside the handles, and anywhere else that the panels had an air gap. All told, it was 5M of seals.

Ok I'll give them a try.
RE: We need a motor noise cancellation update like the Bambu got today.
So are you printing these and cutting them to length? I'm thinking of just printing them the length they need to be. The length of the pieces are set by the holes in the panels so I'd think you could just put together a g code file with all the necessary pieces
RE:
My first thought was to do the same but with so many panels and so many different sizes, I just added them all up and printed a large amount. Remember there are the grounding points that have different widths than the plastic plugs. That makes it even more varied. It was quite easy to cut them to size. The one in the back is the only one I printed to length and that's because it's something like 410mm. Had to be printed on the diagonal.

RE: We need a motor noise cancellation update like the Bambu got today.
Upgraded to 6.0.1 today and performed the new calibrations. WOW thank you Prusa team! SO much quieter! Mine showed a 91% improvement when completed.
RE: We need a motor noise cancellation update like the Bambu got today.
I updated to 6.1. Yeah I see it running smoother and quieter for some travels, but not all. Not that it was all that loud to begin with. Print quality is exactly the same as it was before; really good to excellent. Gee thanks Prusa!
in the meantime the prime tower is still pretty bad in PS so much so that it limits the use cases!
