Creality V4.2.7 Upgrade Mute Silent Mainboard for Ender 3 Customized Silent Board, Ender 3 Silent Mother Board

I am very happy with the current noise level. Easy to install and came with all the required pieces. Since the update all have worked fine - printing like a charm!

UPDATE - it went into a boot loop the second time I put power to it. Seems like Ive waited weeks for this thing to work, with utter disappointment every time. They mean silent when they say it. I can hear the rollers on the extrusions over the motors, seriously. This is the one thing Ive gotten from Amazon lately that wasnt a complete disappointment.

Perfect upgrade!

It took about 25 minutes to replace the original board in my Ender 3. Now, the only noise I hear is from the part cooling fan. Best upgrade ive made to my 3D printer thus far. Worth every penny.

NOT A 1.1.5 BOARD! Im not sure why Creality decided to call this a 1.1.5 board. The 1.1.5 is 8-bit and uses the Arduino IDE for firmware flashing. The 4.2.7 that I received is a 32-bit board, which demands an entirely different firmware and needs a completely different environment for flashing. At the moment, Crealitys own 32-bit firmware doesnt support BLTouch or inductive sensors, and the source code is nowhere to be found, meaning youre SOL if youve upgraded your printer with one of them. Vanilla Marlin 2.0 may work (I havent tried, mainly because Im on TH3D EZABL bed leveling). 3 stars because I appreciate the 32 bit upgrade. All boards are going to be this way in the future as the tech continues to evolve. Im sure the board will be great when programming catches up. However, they SHOULD NOT be calling this a 1.1.5 board. They are not the same thing and cant even use the same firmware.

Ive purchased 2 of these boards, one from this seller and the same board from another. When I first installed it it was completely quiet just like my other motherboard upgrade. But now that Ive had this board from this seller for about 2 months its noticeably louder. For comparison, my other Ender 3 with the motherboard upgrade from another seller has been in use for 6 months and its as quiet as it was day 1 of the upgrade.. Ive run both printers at the same time printing the same file and this board is CLEARLY louder and whiner. Its noise level now is halfway between the stock board and upgraded motherboard(from another seller). ANOTHER ISSUE is when I first installed this board, the LCD screen on my Ender 3 wouldnt work. I had to unplug the screen and reset the printer 3 times before it began working properly. Do yourself a favor and just purchase from another seller.

The install was somewhat involved, but mainly due to my ender 3 having its connections hot glued down. Once that was sorted though, it was plug and play for the most part. Can’t hear the motors at all now, the fans are now the “loudest” part. When I have my ac running at the same time, I can’t hear the printer at all. Only time I notice the noise now is if I’m focused on it. Print quality is really good too, so I don’t think there were any compromises there.

This mainboard (v4.2.7) eliminated the stepper noise on my Ender 3 Pro which was running the v4.2.2 mainboard. Now when I print all I can hear are the fans.

This board is a must if you don’t have a space away from earshot to run your printer, and even then still worth the money.

If you wanna get a motherboard that prevents excess wining sound. The 4.2.7 is worth every penny. I vacationally had to sleep in the living room next to the 3-D printer when it runs and now after this purchase just and installing I can sleep peacefully with less noisy sounds. This silent board is wonderful if you have to print objects overnight.
