Official Creality 3D Ender 3 Pro Silent Motherboard V4.2.7 Upgrade Mute Mainboard with TMC2225 Driver for Ender 3/Ender 3 V2/Ender 3 Pro/Ender 5

It is silent. I highly recommend if your ender 3 didnt come with this or a newer main board. If you are okay with building your own computer or tinkering with electronics, installation will be fine. Else, take your time. I recommend taking a few photos before taking out the original main board so you can reference the locations.

Much quieter than the original Ender 3 board. I did need to flash the firmware so there was soom effort involved, but that kinda goes with the territory... fun evening project :)

Prints have stopped several times unexpectedly, doesnt hold a constant temperature at the hotend or bed

Best update so far from Creality for your Ender 3 Pro! This will eliminate the stepper motor noise! Its absolutely great! If you are running a stock printer, you will be left with just hearing your fans.

Even i was impressed how quiet it made the printer. it also supports his new CR touch

Stepper motors are totally silent now. Print quality is still fantastic. Only trouble I had was flashing the new firmware for my ender 5. But once I got that sorted, its been smooth printing.

This is a great upgrade. I dont have a db meter but after installing the steppers are almost completely silent on my Ender 5, what a huge difference. I followed the YouTube video from Teaching Tech for the motherboard and Marlin upgrade and he walked me through flashing the motherboard with an Arduino Uno which I had on hand already. Pretty straight forward and didnt run into any issues.

I installed this board on my ender 3 pro. Massive improvement in stepper noise. I cant emphasize it enough. Essentially you only hear the fans now. Installation was annoying because Creaility hot glued the wire connections. Also, one odd thing. After installing this board my bed moves to the back after finishing a print whereas with the original board after finishing a print it would push the bed to front. I am talking about the y axis here. I dont like this but whatever, such is life. The product is not perfect but 5 stars because its so much quieter.

I was trying to install a BLTouch on my Ender3 with the 1.1.3 main board. I was not able to load the SW onto that board. I decided that this 1.1.5 board with an installed bootloader would be the easy way forward with the added benefit of quieter operation. Installation was easy. It worked and is much quieter than the 1.1.3 board. Adding the BLtouch was also reasonably easy. I used the Marlin 1.1.9 SW with BLTouch enabled. I loaded it via the Arduino IDE through the USB port.

Worth every penny! Completely silenced the XYZ axis on my Ender 3 Pro. Only thing I hear now are the fans, and Im working on solutions for that. Upgraded from the 4.2.2 board. Direct plug and play, no hassle at all. DO THIS YO!
