As I mentioned before, higher acceleration and speed will cause this behavior. That is just the law of physics.
Did Bambu claim that this is a silent printer?
If you ever owned the first-generation Ender 3 printer of Creality, then this noise is nothing compared to what those printers produced. And they were a lot slower.
With the H2 series there were also people complaining about the filament cutters being noisy. It is what you make of it.
It is all a matter of perspective.
And yes, it also matters where you have your printer installed.
Mine is located in a hobby room. I am not working beside my printer.
Maybe because the only one you are listening to is yourself.
And if there will not come a solution for the helix at all, then simply don’t use it.
You can always buy another brand printer if that is more quiet.
Just to say upfront, I did see the IF, and I think you’ve hit the nail on the head. I’m wondering whether something like this actually exists, because, as you pointed out, physics gets in the way. Even inkjet printers make noise due to their mechanical movements.
And just to be on the safe side: this comment is meant to be taken with a smile and a little chuckle!
How do you see this situation ending if the solution you’re hoping for doesn’t materialize and you’re not willing to use the available workarounds? The printer will still be noisy, and somehow the focus seems to have shifted completely away from your family.
So here’s a suggestion: Why not simply sell the printer?
Wouldn’t that be the best solution for your own peace of mind and, more importantly, for your family’s well-being?
I mean this as a constructive suggestion, not as an attack. Sometimes letting go of the problem is the best way to move forward. This is probably less painful than spending months fighting over it, only to end up with no solution anyway.
