Ender 3/Ender 3 Pro V4.2.7 Silent Board

I purchased this as a upgrade for my ender 3 pro and it is amazing. I cannot understand how just upgrading the motherboard can silence the motors. The motors are whisper silent and all that can be heard is the fans now. Very easy to change the board just a few screws and re wiring. One thing I do like is that you can now flash firmware onto the board with a micro SD, unlike before where you had to get several connectors and software, so that is a lot easier now. I noticed they is 2 extra ports on the board compared to the old one, I found out one is for the BL touch and the other is for a filament run out sensor so I will look to buy them in the future. I heard that with upgrading the motherboard can make the print quality better. I print a lot so I know if my print quality has worsened or got better and I have to admit I cannot see and difference. Is it worth it?: If you are wondering whether it is worth buying, I would definitely say yes. The new board has lots of new features that the old does not which makes it a lot easier to use.

After bringing my Ender 3 pro in from the shed, I didnt realise how noisy it was. After adding Noctua fans I decided to upgrade the motherboard. It was an easy install and The printer is now virtually silent and cannot be heard from anywhere except when you are stood near it. Amazing difference and worth the price. The firmware was easy to find and it works well with my bltouch copy.

I purchased two of these to replace the stock boards, one of which had a broken SD card slot and both was slow due to the 8-bit architecture. These boards are much faster given they are 32-bit boards, they already contain a boot loader so firmware upgrades are simple. The first thing I did was install the latest marlin with a few tweaks and M600 enabled. Both printers are printing fine and are noticeably quieter - pretty much the same as my Ender 3 Pro V2’s. I could have opted for 3rd party boards but honestly, the printers do what I need them to do very well and I like that I can achieve that without going mad with 3rd party parts.

Straightforward to fit but does require some disassembly. Once fitted, stepper motors are super quiet with a very low noise level, board is now 32 bit instead of the older 8 bit, will now make Firmware upgrading a lot easier !! Will also see if the print quality improves. Maybe a touch screen next? A very worthwhile upgrade !!

all the videos I watched made it look easy but I was very concerned about me bltouch as there are lots of stories of incorrect wiring and frying the board . it took about 1 hour to change over the board and then remove the wires out of the bltouch plug and change the order from red blue yellow to blue red yellow and all my fingers and toes were crossed when I turned on the power . no bang no smoke, thank god for that …as it turned out all that was the easy part , the board was billed as pre-loaded and just plug and play , well yes and no the firmware was very basic no power cut recovery no change filament no bltouch AND unable to adjust the nozzle height below +000.00 . after many many hours scanning the web i got it to work . my prints improved a lot with the bltouch but now they have improved a lot more and the only noise heard is the fans and the filament drum moving .......well worth the money and would recommend but just be aware things may go wrong

This board does exactly what it says on the tin and I was blown away by just how quiet my printing is now. The only noise comes from the fans which I'm also looking to replace.

Ordered this item & couldn't get stepper motors to run, contacted seller & received excellent level of support & help, ended up getting a replacement board & flashed firmware & now everything is running perfectly, Excellent customer service & support, would highly recommend this item just for the support given.

Well impressed with this. Didn’t believe that this would make such a big difference on how much noise the motors made but it does. Pretty easy to change out wish I would of done it sooner. Definitely an upgrade worth doing.
