Switching from printer to another ,Up studio lost all the leveling data,What happend

Several possibilities:

1. SD broken or loosed:

To correct it, you need to power off the printer, take out the SD card,  insert the SD card, and make sure the SD card seat in well, then restart the printer.

2. Upgrading to a new version of UP Studio causes the incompatible data.
3. Unpredictable instances happened, e.g. Power outage, or interruption occurred during date transferring process.
