Hi everyone,
I am repairing a stock Creality v4.2.5 mainboard from a CR-200B 3D printer after some liquid damage. I have cleaned the board and replaced the broken full-size SD card slot with a PROCONN 03342B1 slot.
The printer boots up normally now and no longer freezes, but it does not recognize the SD card (“No SD card”). I suspect there is an issue with the Card Detect (SD_DET) pin mapping or logic on this specific board version. Does anyone have a pinout diagram for the v4.2.5 board or advice on how to properly bypass/wire the SD_DET pin?
Thanks in advance!
