Authentic Creality 4.2.7 32 Bit TMC2225 Silent Control Board with Filament Runout Sensor, 24V Ultra Silent Fan for Ender 3 / Pro / V2 / 5 Includes 1M Capricorn PTFE and Other Accessories Upgrade Kit

So where to start? F1st Layer has been an excellent company to work with. This product is by far one of the best items purchased from F1st Layer so far. It is extremely quiet! The biggest drawback was the install, if you purchased the BLTouch kit from F1st Layer you will need to swap the pins on the power cable for the BLTouch to match the pinout on the new silent board. Also F1st Layer includes Capricorn tubing and couplings in just about every package so dont worry about running out!

This has drastically reduced the whining from the motors. Unfortunately the board package was damaged. It seemed that everything was packed too tightly and one of the heat sinks broke off the board. I had to buy thermal glue, let cure for a day. But after that it worked great! Additional pieces are good, I used the springs and new tube. I can’t speak to the sensor or the the fan as I didn’t try these out.

The kit has all the hardware needed and more. You should take note that the driver connectors are 180° from 8bit boards and that there is a lot of confusion around the net about that. I checked if the polarity was switched around as it was several indicators of this. However the polarity is correct with standard cables, no need to swap in connector as some sites claim. If there is one thing I would add to this board, it is a secondary driver for dual Z axis. The USB fits fine into the chassis if youre upgrading from 8bit. Changing FW was uneventful and worked first time. I am using mine on an Ender 5. Steppers are also of the quiet kind.

Truth told, easy to install only gets a 4 rating because Creality saw fit to put the mainboard upside down in the housing, and its just a pain in the --- to get in there. The meat and potatoes of this one is, as an upgrade, it borders on essential. All the screaming the steppers did when my printer was new has been practically silenced with this board installed. Its also more capable than the stock board I had as far as installing a BL Touch sensor. (If you choose to install one of those - and you should - make sure your wiring is correct so you dont cook anything!) Worth the buy for sure, if only for the quiet operation. If youre a real modder, though, make sure you see if you arent interested in other makers boards. There are a LOT of expansion opportunities.

update 9/15/21: well that fan making funny noise... well it died today. this fan did not run that long. guess you get what you pay for. update 9/21: all was well for few days, than stepper motors started to sing. found out it was board that was causing it. Contact Amazon and they sent me replacement. figure all will be good, but no. fan started to make noise on start up. takes about good 30 seconds or more and noise will stop (maybe need oil?) anyhow, replacement package arrives... again, static protection bag is open, and missing fan. anyhow, after install the board, it made noise and noticed filament runout sensor firmware was not flashed... WTF... after flashing firmware almost all stepper motor noise went away. (hope it stays that way) I dont know, maybe its just me having some bad luck or something. feels like these are 2nd hand or something that got returned and these 3rd party sellers buy them in bulk, put in box and resell. overall it sucked. replacing these boards arent fun. short wires and small spaces. hope this board lasts, cause I dont want to go through this again. Install wasnt too bad. remove wires, swap out board and reinstall all the wires. only thing was when it was booted for the first time, EEPROM thing came up, which community helped out solving. ill say, it is so quiet! it is so quiet now that i keep thinking it stopped printing. also hot end fan is lot quieter than stock version. i definitely recommend!

This is a very small company, but they provide excellent service and stand behind their products. The Sprite extruder showed up quickly and was easy to set up. I had one question and James was able to answer it quickly and I was up and running in no time. You have a lot of vendor choices, but I really recommend F1rst Layer!
