Official Creality New Upgrade Motherboard Silent Mainboard V4.2.7 for Ender 3 Pro 3D Printer

I recently upgraded the motherboard along with many other components of my stock Ender 3 Pro. My favorite is this "silent" motherboard; it's very strange to be able to hear just the fans and not the loud whirring/grinding motor sounds as the print progresses.Installation is fairly simple from v4.2.2 board to v4.2.7, as all of the motor headers and wire screw terminals are in the same location - it's literally just a straight swap from board to board. I do recommend crimping ferrules on the tinned wires for board power, bed and nozzle heating, as the solder that's placed on the wires does sometimes fail and cause power issues.A tip I found on Reddit I believe: use rubbing alcohol to remove the glue on the plug headers when you pull the plug off the old motherboard. I'm sure other techniques can work but rubbing alcohol is super easy and doesn't risk extra damage like a heat gun would.

I changed the card of my 3D ender creaty, because I damaged it by mishandling the motors, changing it was very easy, no need for instructions or youtube videos if you have a basic knowledge in 3D. The best of all is that it is silent.

I keep my Ender 3 Pro in the basement. With the stock board, I could stand at the top of the stairwell and hear if it had finished a print yet or not. With this board, I can be standing right next to it and still have to look to see if it’s running, it’s THAT quiet.Installing it wasn’t difficult either. I love that I didn’t need to mess with firmware at all - just plug it all in and it was good to go.

I like how the 4.2.7 board quiets the stepper motors and allows for a better overall experience. Now if we could just get it to modulate the fan better at regular operating speeds without tweaking the firmware. Heat sinks were mounted slightly crooked on mine and could use a bit more thermal paste. Overall decent, but I still prefer the BTT SKR MINI E3 V3 as of now. Will update after some time using this

Quite easy to install, has connectivity to CR-Touch, makes the ender-3 printer really really quite! Only the fans are a bit loud.

It is so much quieter with this board. Super quick and easy to install and worked instantly. The printer now only makes fan noise.

Honestly I still don't know what went wrong but the board is dead. First time printing went incredibly smooth. Turnded it off and then the next day I turned iton and started to preheat. Everything froze after getting up to temp. Then it made the stepper motors have an awfuld grinding whirling noise almost like a fan has spinning up. Ever since then that's all it does and won't boot up. I've tried updating firmware and checked all wiring to insure nothing was hooked up wrong but the board was hooked up correctly and the firmware won't update. Another thing to note is none of the connections look good on the board. The solder is fine but the actual plugs are all crooked and looks like it was done in a rush. So I guess buy at your own risk.

It was super easy to install, though that may be because I also installed the Spider Hotend at the same time and this was easier in comparison. Makes the printer software much easier to install, and drastically reduces the stepper motor noise. Now my printer is almost silent!
