Why does Ortur Laser Master 3 keep flashing in red and green or sometimes in yellow and white with intermittent beeping ?
Ortur Laser Master 3 does not recognize the SD card. Please make sure that the SD card is inserted normally. If it still flashes after the SD card has been inserted, please reinsert the SD card or restart the machine. (Note: The machine must be inserted into the SD card before use, generally in no special circumstances, do not remove the SD card, so as not to cause the machine lighting display abnormalities and some engraving abnormalities).
