Hi, I installed a 4.7.2 board on my ender 3 V1 and out of the box it worked fine, pretty silent indeed.

Then I wanted to upgrade my firmware to allow my Creality BL Touch to work also, so I downloaded V4.2.7-Ender-3-32bit Mainboard_Marlin2.0.1- V1.3.1- BLTouch - TMC2225.bin from your website.

This seemed to work fine, after flashing the unit started up but also the buzzer started beeping continuously so no longer that silent...

On start up all seems ok, the BLT is extracting a few times and on the menu the BLT settings are visible, but not much additional happens.

I tried with both the new on board connector (swapping the cables so they are correct) and the old 8bit add-on board as shown in one of your videos. But with the 8bit add on I got no screen at all, so I'm wondering what you really do in the video compared to what I do.

Anyway, can someone tell me how I can get rid of the constant buzzer, or tell me where I can find the original firmware so I can put it back to factory settings? At least this way I can still enjoy the silent steppers and just return the BLT.

It's either that or reinstalling the old 8bit board and return everything back because this is not the quality I expected.

Same for me, ordered a 4.2.7 silent board and it was silent indeed. At least until I installed the new firmware so I could use my BL touch and then the buzzer started beeping continuously. On the internet I could find some relation with a shared pin for the buzzer and the BLT linked to the Marlin software, so it appears the creality version has the same problem.

Advised differ from cutting cords to ripping off the buzzer so not too happy about this so far.

Hi Bjorn, did this work for you?

I'm having exactly the same problem, bought a creality kit for my ender 3, but am not able to flash the eeprom, the error message is stating Chip enable error while everything seems to work correctly. There is a blue light on the board, the USB turns to blue when I want to save but then after a few seconds the thing fails and I get the error, when following the instructions to the letter...
