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

I have an Ender 3 Pro and I ordered this board to help upgrade it. Long story short: They do not come with 1.1.5 Firmwear(1.0.1 intead), It locks up an Ender 3 Pro to the point of not functioning at all, and if you try to update the firmwear, it sets off the thermal runaway alarm and bricks the printer until you kill the power.

Not only is it quite operation now but being a direct drop-in for the 1.1.3 Creality board it is a no brainer. This board should be one of the first upgrades completed for your printer. Thanks

Im not sure what the Warmth, Noise level and Thickness options are doing on the Rate features thing on this page means but 5 stars for this seller!

The best upgrade for my ender 3 pro.

The thing is quit

eliminates all noise but power supply and extruder fans, only time I will ever write a product review because its that good

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.

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.

It works just fine and was easy to install

So, I managed to overheat my 4.4.2 board stepper drivers, and was getting wild y-shifts. Installed this board, and everything is fine along with an 80 mm fan for better ventilation. Very easy to load the firmware - finding the correct one is another matter. One small annoyance is the USB connection (I use Octoprint). Went through several cables until I found one that would work reliably. Odd - must be an electrical noise issue on this board. While troubleshooting the issue I saw several other posts concerning USB connectivity, so its not just the board I received. Other than that, its a good price and seems to print very well.
