What if the key to silence the Creality Hi.... ... wasn't just a question of speed? When I bought my Creality Hi, I was seduced by the promise of a noise level of around 48dB in silent mode. This silent mode finally arrived a few weeks ago, in the latest firmware update, and it consists of reducing printing speeds to below 50%. Wow, the result is impressive in terms of noise, with a reduction of up to 20dB! But at what price... I did notice, however, that the most annoying noises were major jerks when changing direction or taking over lines. It's hellish when you're filling in a small area... So I reduced the acceleration. By half. And the result is clear. 18dB of noise reduction for only 13% increase in printing time. At this stage, it's the fan noise that dominates. There's no need to slow things down any further. You can find a “silent mode” profile on most of my designs, so try it out on this RFID tag for Soleyin Spools. And don't forget to give a like or a boost if this advice seems well to you !
