An error message appears during use: “Can not find valid lmc1 device”

in FAQs about Laser Marking, ,

“Can not find valid lmc1 device” and “invalid command” will appear during use, and it will be normal after rebooting, once or twice a day.

This situation usually occurs in a 32-bit system, which is equivalent to a card loss.

  • First, check the communication between the board and the computer.
  • Replace the USB interface or try with another data cable.
  • You can also try with another software.
  • If it still doesn’t work, use a genuine 64-bit system to try.
