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

I purchased this to silent the stepper motors, and it did that perfectly. The old board was swapped out in 30 minutes. The only downside is that the firmware has a bug, where the extrude will stop around the 30 to 40 percent mark of a print. This has only happened when the object is sliced with Simplified 3d. Good news is that the firmware can be updated to fix this issue.

Awesome upgrade. An absolute must for and Ender 3Pro. Do this before you upgrade anything else. Instantly quiet.

Poor instructions.

When they say its silent, they really mean it! I cant hear the steppers at all over the normal fan noise. The board is well made and installed easily. Upgrading from the stock 4.2.2 board was 1 to 1, all the connecters are in exactly the same place. Editing and compiling the Marlin 2.0.x firmware that I downloaded from GitHub involved a lot of trial and error before I got it right. I had to watch about a dozen YouTube videos, and combine the information gleaned from them, before I got it dialed in. If youre not interested in fiddling with code and re-routing wiring, I wouldnt recommend this project for you. This board, plus the BLtouch bed leveling probe I installed, have made a good printer great! I very happy with the purchase!

Got it in because stock motherboard fried. Super quiet can’t hear it run other than the occasional low chirp. Got my printer back up and running.

10/10 love this board, it took away all noise except fan noise on my Ender 3 pro. Going to be buying a second one for my other printer.

I keep my printer in the room next to my bedroom. When running overnight prints I could hear the printer making all kinds of racket. It would on occasion wake me. The Silent board does exactly what its supposed to. The installation was a bit of a hassle on my Ender 3 Pro, since the printer has to be turned on its side, or upside down to get the board out and some of the wires are difficult to remove. Part of the removal involves taking a copious amount of hot melt glue off the plugs. Creality wants to make sure the plugs stay inserted and I assure you, they do. I was very careful and even used a hot air gun to soften the glue. This helped a lot. When I first looked at the old board it was a little intimidating. I couldnt see all the mounting screws. It also looks like a lot of wires and plugs to remember. Fortunately all the plugs are labeled. I managed to get everything out and back in again and finally got the board installed again. The new board works great! I later discovered, thanks in part to some fellow Amazon reviewers, that there is a bug in the firmware, version 1.1.8 that can cause some prints to stop at about 35% completion. This required flashing the board. I dont know if having to learn how to flash was good for me or not, but flash it, I did. Again, thanks to fellow Amazon reviewers, I got the tips I needed to allow me to make it happen. A few words of advice on flashing this board: It already has a built in bootloader, so plugging the printer directly into a computer via a serial port is all thats needed as far as flashing hardware. I went to TH3D and downloaded their firmware package and watched a video on youtube that showed me exactly what and how to do it. The TH3D flash is based on a Marlin flash, but tweaked a bit, and it includes all the settings needed for the Ender 3. With this in hand its possible to flash the board in 10 minutes or so. Its not Crealitys fault the bug exists. The bug is in the Marlin version, so I didnt knock off a star. After all I did learn how to flash my board and this paid off very handily when I updated to ABL. I really like using my printer now, and running it all night means only a whisper from the fans. I can live with this. Perhaps I will eventually replace the fans with quieter ones, but for now its great.

The board works very well... very quiet... But beware if you have an Ender 5, as the stock firmware for the board is set for the Ender 3 - which has an entirely different physical layout and will cause the servos to attempt to autohome to the Ender 3 form factor. The flashing of the firmware for the Ender 5 is not self-explanatory. I almost returned the board for this reason, but I was eventually successful. My recommendation is to search for a tutorial at (link removed per Amazon review policies). (1) Dload the 1.1.15 Ender 5 hex file firmware from Creality dropbox. (2) Install AVRDude (3) If you have a linux system, you have it slightly easier. Plug into the usb on the board and copy/paste the following CLI command: sudo avrdude -c arduino -p m1284p -P /dev/ttyUSB0 -b115200 -U flash:w:/home/user/Downloads/ender5.hex That should do it.

I looked at the bottom where it says Ender 3/5/blah blah instead of the top of the description where it says Ender 3 Pro. If you have an ender 5 dont buy a 3 Pro board unless you want to compile your own firmware which I am apparently too dumb to do lol.

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.
