Hi, my name is Jean-Claude and I live in France. I bought a Fysetc Cheetah V1.1b . It's wonderful, the engines don't sound, but I have problems with the SD card. . On the SD door it turns on the LED light but does not read the card. The screen always shows the message "Please insert SD card". .I have the original marlin firmware
I would appreciate your help, I'm already very complicated to find no solution. Thank you
