Power Loss Recovery
There are two methods for power loss recovery
1. No extra module needed, the motherboard will write current print status to the SD
card after every layer is printed, which shortens the life of the SD card severely.
#define POWER_LOSS_RECOVERY // enable power loss recovery
#define PLR_ENABLED_DEFAULT true // true default to power loss recovery
enabled
2. External UPS 24V V1.0 module, when power is cut, the module will provide power
to the board and signal the board to save current print status to SD card. This method
has virtually no effect on the life of the SD card.
