If you spot that the information of the file that you will print is not correct, it's bugged or the system asks you to insert an SD card even though you have one plugged in, you are experiencing SD reading issues. It is also possible that during the printjob, the screen shows illogical values or the printer moves in a strange way. Follow this troubleshooting guide to locate the issue:

Conclusions

Usually, the reading problems are caused by the SD card and in fewer cases by the SD card reader. If you are using a micro SD card adapter, check if it is okay and try to change it before changing the SD reader.

Is important that the SD card is formatted in FAT32 to ensure the correct reading process.
