Creality V4.2.7 Upgrade Mute Silent Mainboard for Ender 3 Customized Silent Board, Ender 3 Silent Mother Board

My product caught on fire a week into using it, everything was wired correctly and working, i own multiple printers and have had these boards replaced in half of them so now it draws for a big concern, quality control is clearly shotty so i can’t recommend, they work great when they’re not catching fire, i understand this is always a possibility but a week in is just insane to me, hopefully i can get a return as it’s been close to month and i no longer have the box for it, but it also destroyed my BL touch in the process, so i got a bitter taste in my mouth, i really hope you guys can ensure these products wont do this consistently to others, thankfully i was home at the time and caught it pretty early in.

My ender 3 had an E1 error that bricjed the 4.2.2 board. 50 bucks and the thing is so much better im mad i waited.

This reduced the sound on the stepper motors by about 99%! It is almost unbelievable how quiet my ender 3 runs now. There is literally no increase in volume from when the printer is on and idle to when it is printing. The only sound it makes now is from the fans. Printing is totally silent!

It made the Ender3 Pro super quiet, but the stand alone TMC2208 chip for the extruder would trip out on overload typically around the 2hr point. Resetting it and immediately starting resulted in failure to feed. Letting the machine cool for an hour or so would result back to the 2hr print fail. Added auxiliary cooling (even to the point of setting it on top of a box fan) with no success. So I set this board aside to see if I can change the Vref or possibly get a better motor. I spent a day and a half checking hot end, clogs, binding, etc, but everything was smooth running and wouldnt subject the motor to extraneous stress. So on the fence, about this upgrade.

I run this board in an ender 3 pro. The silent drivers are very good at quieting the stepper motors. It is relatively easy to set up with a little bit of knowledge. This board can be even better if you modify the firmware. Print quality is great.

Nearly silent, this thing is 100% as advertised. Could not recommend it more.

Bought 2 ender 3s and setup my first printer, used it for 2 months while I stockpiled some upgrades for the other while I learned about 3d printing. I thought the sounds it made were super cool and didnt bother me, but the Motors whining bothered my wife. Happy wife happy life, ordered a silent board too. I put together printer #2 (at setup I added dual z kit, direct feed extruder kit, new leveling springs and wheels/knobs, as well as this silent board) and with all my upgrades installed it fired it up and did a quick test print, basically sounded idle, just like when you arent printing, but the fans are on. This board blew my mind... Well maybe my first machine was just noisier anyway? Nope put a silent board in that one too, super quiet. Now that my printers are quieter, i realized I didnt really like the motor whine after all. My wife? Happy they dont make as much noise now, she didnt even freak out when she saw the second printer (which she didnt know I had for a month lol) Also firmware flash is a snap for 32 bit boards, ignore the complex videos, just drop the binary file from creality website (pick the right one, mine was just the basic cuz no auto level kit) put the binary file on a BLANK SD card, with printer off, insert SD card, power printer on, wait a minute for the blank screen to pass while it updates. Once it boots up, check you printer firmware in the menu and confirm its what you were expecting. Came preloaded with ender pro firmware from like 2020. Side notes, direct drive kit is cool, I bought it for tpu, nothing special. Dual z kit is cool, critical if adding direct feed extruder, helpful at keeping z from slouching on a bowden, but you dont need it. The knobs and spring kit for bed leveling is my favorite upgrade on the cheap, holds great, I rarely have to re-level, with stock springs I had to re-level pretty much every print. Octoprint/octopi brings it all together so so sweetly, i have raspberry pi on hand most of the time, so I just set it up on a 3b+ as soon as I discovered octoprint. Been running fine, threw another instance of octoprint on a pi400 for the second printer. *If you dont have octoprint setup, that is Upgrade #1, the one upgrade to rule them all. So after octoprint, this silent board is my favorite upgrade, my stock boards were 4.2.2s so no print quality improvement, but the silence is worth gold, quieter fans installed is inevitable now. Worst part about this board, uninstalling the stock board. Creality Hot glued the plugs closed, i hear they recently started doing this, maybe they want to void a warranty, but Im the kinda guy that if I buy it and it works, its mine, i fix my own stuff, I was never going to send this machine back, just replace bad parts if theres ever a failure. You do risk breaking something, however I was able to extract 2x4.2.2 boards without damaging them, and even still, you can just use your new board if you damage the stock one, install is pretty easy without glue everywhere, have some tweezers handy to hold wires into terminals while you tighten them in.

Pretty much plug and play, and no more whining as the printer works.

We had a bad board on one of our printers...the extruder only extruded at half speed despite checking vref, voltages, and esteps. Put a new board in and worked great. However, I cant BELIEVE how much quieter it is! Ended up buying another for a second printer that was having issues and had a 1.1.3 version. I have a feeling the 3rd printer isnt far behind as it will sound very noisy now compared to the two with new boards...

Surprising how the printer is quiet now. Works fine.
