Official Creality New Upgrade Motherboard Silent Mainboard V4.2.7 for Ender 3 Customized and Non-Standard Matching,Ender 3 Silent Mother Board

Prompt delivery. The boards looks well made.

Remarkably quieter than the stock v1.x boards. Very easy to install, just make notes of what goes where before diving in.

Even being in the next room, my Ender 3 Pro would keep the wife up at night. My 4.2.2 board was noisy! Its a newer printer, after Creality moved to the Chinese knockoff H4988 drivers, so Im guessing thats whats under the heatsinks on my old board. I had already printed a silencer for the power supply fan, and after this upgrade, its eerily quiet. I can still hear a tiny bit of motor noise at certain speeds, but I can talk on the phone right by my printer now. Once I install the Hero Me with dual 5015 blowers for print-cooling which I can run at like 30-40% speed and cool up the wazoo, as well as a silencer on the 4010 axial fan for the hotend, I think Ill barely even be able to tell its running. If youre debating about this, Ill tell you its totally worth 50 bucks. I havent noticed any print quality change, but the noise difference is astounding. The wiring was tricky, but just take pictures of where everything goes. The connectors were all hot-glued so I had to pry the glue off with a small screwdriver... thats the hardest part.

Ive had my ender 3 pro for 2 months now and I have it running around the clock. Since I installed the silent mother board its a night and day difference in sound. I keep checking to make sure its running because its inaudible unless I have my ear inches from it!

firmware will not upload. printer is inoperative now

This new motherboard makes my printer super quiet it is smooth and the print quality is great. The hardest thing about the install was removing the glue from the previous factory motherboard. I am very happy with my purchase

My never 3 v1 was a loud scary sounding machine. Now it’s quiet and you can literally barely hear it.

If you just purchased an ender 3 and are annoyed by how loud the machine is, THIS should be your first upgrade purchase! It makes all the difference in the world. Literally takes the machine from “I can’t have it in the house” to “I can sleep with it running” After this I recommend upgrading the fans to noctua for almost complete silent running.

I had been fighting a progressively worsening layer shift in one axis. I tried adjusting belt tension, bed screws, rollers, and everything else I found in the tutorials. Nothing worked. Finally saw a mention that the motherboard can overheat and slowly degrade. After a few tests I realized this was my issue. I replaced the motherboard with this one, my print quality has greatly improved. Motherboard runs much cooler than the original. An added bonus is a quieter printer! Highly recommended, especially if you have layer shifting caused by an overheating.

Arrived on time, with adequate packaging (cardboard box, foam, electrostatic bag.) I recommend taking a photograph of your existing board before after pulling it from the printer but before removing any wires. The installation was relatively easy -- the wires are hot-glued down, but the glue is easy to remove. In my install, I screwed up one wire (the lead to the bed wasnt in solidly) but it was obvious to fix. The stepper motors are now silent -- the only thing you hear is the fan (and mostly the PSU fan I think.) Its dropped it from about 75dB down to about 50dB. HUGE difference. Dont see any other differences, but not having sketchy sine waves should mean more precision (but I havent dialed my printer in to that degree, so...) You will need to reflash (but its easy, just a matter of putting a small SD card with the new binary in the root and rebooting). The one it comes with has the temperature double print error and is from April. Happy purchaser! I highly recommend this hardware upgrade.
