Hello, I have an Ender 3 original, no BL Touch or other add-ons. I use PNY Elite-X micro SDXC Flash Card 64GB. I have been using these cards for quite some time and have had no issues until now. I use Creality Print, latest version. I load a model onto the chip, put it in the machine and it will not mount, I have tried other chips and the same thing. I have not done anything to the machine, loaded new software etc. I have cleaned the slot by blowing air into it and even taking the board and looking into the slot., cleaning the chip contacts with a pencil eraser ,And finally replacing the 4.2.7 mother board and still have the issue. I bought new chips, 32 MB and 64 MB the same issue. I have exhausted all avenues I know of with no positive results. Any help is appreciated.
32 GB and 64GB not MB
