I just finished building my K8400. All is working, temp, movement, filament load… When I put in my SD card it is not being recognized. I have tried two different ones and the LCD just says, No SD card.
When you put the card in and scrolled down to the option “Print From SD” there should be a selection one more step down from that “Init SD card” you need to select that first then go to the “Print from SD”
if you pull it out and add a file you need to select “Change SD Card” to refresh it.
thank you, that worked. sorry to bother you with such and easy question
No bother at all.
The reason I knew this is because I went through the same thing.
