The problem is inside out ANC is a very different ballgame to outside in.
With ANC headphones, all the sound it is trying to cancel is travelling along your ear canal in basically one direction.
With this, the sound is being produced all over the printer and being broadcast at different levels in every direction. The only real way to apply ANC like you’re talking about on a printer, would be to basically surround the printer in speakers facing inward to cancel the sound waves before they reached you.
This is really nice! I mainly print ABS so there aren’t any loud fans going and it’s really quiet. I used to get so tired of hearing the same tune over and over again when printing tall things. Thank you so much for this update!
Its fun now to go back and see who said all the noise was from fans and that noise cancelling couldnt do much at these speeds anyway. Lmao. It is so nice. Noctua board fans, exhaust mufflers and unmounting the aux fan from the side panel are the final touches.
Could you please point me in the direction of what Noctua fan to choose as well as maybe walkthroughs both on this replacement as well as decoupling the aux fan from the side panel? Would it make sense to replace the chamber fan with a Noctua alternative as well?
You need to print a stand for the aux fan. The noctua board fan swap can be found on this forum. The chamber fan can be swapped to noctua but youll lose like half the air flow as a trade for noise. Just print a muffler for it.
I am running the calibration now. Can’t wait to see the difference.
Its interesting how they do it. They find the resonant frequency of the mechanical system, and then I assume avoid hitting those resonant frequencies while printing.
It will probably also extend the life of some parts because they aren’t vibrating at their resonant frequency.
Finally got around to printing something. It is amazing how quiet it is now, it is kind of weird after getting accustomed to the noise it used to make.
