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

It really does make printing quiet. Best $ spent on upgrades.

The board was a drop-in replacement and went in without too much hassle. Also, it’s miraculously quiet compared to the stock board. The problem with the 1.1.5, though, is how the Trinamic drivers are connected. They’re in legacy mode, not UART. By default, they run in StealthChop mode, which really is quiet. But it’s also lower torque than the original drivers, so sometimes it skips steps. Out of the box, my 1.1.5 board was skipping steps on the Z axis and gave me a few weird layers on a small print. I think it was also skipping on the extruder. When the drivers are wired in UART, you can selectively switch them into SpreadCycle (louder, but better torque) and also tweak the drive current through the controls. But on the 1.1.5, they can’t be switched to SpreadCycle. Drive current can be adjusted, but this is manual on the board, not in software. I returned the board. I probably could have adjusted the current higher to help with the Z and extruder skipping, but without the ability to switch out of StealthChop mode, it’s not a robust solution. I ended up getting an EZboard Lite from TH3D, and the thing is awesome - quiet, reliable, full support of the Trinamic features, easy firmware upgrades, and good general support. You get what you pay for. The 1.1.5 is quiet, but with the way they connect the Trinamic drivers, they leave out a lot of the benefits I thought I was getting.

I purchased this as my Ender 3V2 had the layer shift issue associated with the 4.2.2 board. I simply swapped out the board and had the appropriate 4.2.7 firmware ready on an SD card. Inserted the SD card, powered on the printer, it flashed the new firmware and I was off printing.

Okay, learned a lot about this board. The firmware versions on the file and screen dont match. I flashed to the latest Marlin firmware provided by Creality and found the screen only reads 1.1.2 instead of the version 2.0.1 that may be installed. The version that came on the board did not support my CR Touch. The clamps for the wired were a bit finicky. Once I did all the leg work the board seems to be working fine.

The printer is super quiet now. I forget it’s printing at times. The noisiest part of the printer are the fans now.

I have prints going on in my bedroom over night and i hardly hear my ender pro3

Wanted to love this board - it printed, silently as advertised, for about an hour before the extruder stopped working. Got a quick replacement from the seller, this one had the exact same issue out of the gate. Contacted the seller, they offered a 1.1.4 board (not silent) as a replacement as another 1.1.5 board would just have the same problem. So... theyre selling equipment with known issues? What?

Do i even have a 3d printer anymore?

The install was somewhat involved, but mainly due to my ender 3 having its connections hot glued down. Once that was sorted though, it was plug and play for the most part. Can’t hear the motors at all now, the fans are now the “loudest” part. When I have my ac running at the same time, I can’t hear the printer at all. Only time I notice the noise now is if I’m focused on it. Print quality is really good too, so I don’t think there were any compromises there.

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.
