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

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.

Purchased because I shorted the standard board in my ender 3. I didnt realize how much of a difference it would make. The loudest part on my printer now are the fans. Highly recommend it to anyone looking to upgrade the board without breaking the bank.

Very easy to install and its super quiet.

This board is a must if you don’t have a space away from earshot to run your printer, and even then still worth the money.

The thing is quit

Installation was fairly easy and the detail diagram include made it easy to get all the connections back right. I only had one minor issue, it wouldnt get past extruder heating, just keep fluctuation 5-10 degrees once it got to temp and stuck at extruder heating step. If you encounter that just do a PID auto tune. Afterword it worked flawlessly and crazy quite compared to stock board. Now I just need to figure out how to quite the fans. For anyone unsure of how to do a PID auto tune: For ender 3 printers you will need a computer, USB cable, and a tool like pronterface printrun. For detailed instructions check out BV3D youtube channel for their PID AutoTune your Ender-3 V2 video.

Upgrade was not hard. Took about an hour, half of it removing my existing printer mods, OctoPi, camera, etc., labeling some of the cables with a marker and taking plenty of photos along the way, just in case. Id say much easier than the initial printer assembly. I cannot believe how much smoother and quieter the steppers are on the new board. I was going to say whisper quiet, but I can hear a whisper. The only sound now is the fan. Took noise measurements during print before (48db) and after (36db) to back my impressions up. Besides the TMC driver upgrade, the new board comes with Marlin 1.1.8, includes thermal runaway protection and bootloader for easy firmware upgrades. I upgraded firmware on my previous 1.1.4 board (which might affect warranty), but see no reason to mess with the new one for quite a while. I purchased my printer from Comgrow as well and have had a great experience with them. Including customer support interactions during my first 2 weeks of learning - they were always responsive and more than accommodating. Big thumbs up!

This mainboard (v4.2.7) eliminated the stepper noise on my Ender 3 Pro which was running the v4.2.2 mainboard. Now when I print all I can hear are the fans.

sooo quiet only hear fans now on my ender 3 max

This replaced the original mainboard that came with my Ender 3 Pro. This board is much quieter, and has a dedicated connection for a BLTouch was is nicer than needing to use the adapters.
