CR10 V2 Seems functional but will not recognize SD card or PC connection (lemmy.world)

A friend of mine had a Creality CR10 V2 which he purchased some time ago. Evidently it had a bad board in it and he received a replacement but never got around to installing it.

I now have this printer and have replaced the board in it. I have tested the movement along each axis and tested the extrusion. Everything looks to me like it should be ready to go, but I haven't been able to get it to recognize when an SD card is inserted or when I have a computer connected to it.

I'm a 3d printing newbie and I'm not sure where to go from here. Is it me? Am I doing something wrong? Or is it the printer?

Any advice or guidance on this would be appreciated.

Thanks!

I don't have this printer, but the Ender 3 1st Gen. So here are some suggestions for things, I've noticed on mine.

NTFS doesn't work. So did you format the SD card with FAT32?
Is your SD card maybe too big and did you try smaller cards, with 4GB capacity for example?
Depending on your PC and the Mainboard of the CR10 you might need an FTDI driver to get it work. Did you check, if your OS recognises the printer in the device manager (Windows) or with lsusb (Linux)?

Still no luck getting it to recognize the laptop or the SD card.

Here are more details....

I am using Windows 11. Updates are current. All drivers are current. The printer was not showing up in Device Manager, so I tried installing the FTDI driver as suggested. The printer still does not show up.

I am using an 8GB SD Card. This is an actual SD card, not a Micro SD with an adapter. This is the smallest SD card I have at the moment. Do I need to go even smaller? Do they still make those? :) The SD card is formatted with FAT32. I even completely reformatted it, just in case. (Full format, not quick)

The printer still says NO TF CARD after I insert it.

I am using the Creality slicer, version 4.8.2-254.

Going to Printer Info, it tells me it is:

Creality 3D 1.1.6 CR-10 V2

One thing I have noticed is that if I turn the printer off before unplugging the USB cable, it appears to be getting partial power from the USB port. The screen will flicker until I unplug the USB cable.

As always, any guidance you can give me is greatly appreciated.
