Laser Is Still Marking When the Marking Software Is Turned Off

Fundamentally speaking, this is a normal phenomenon, because the marking command and marking content of the Ezcad software have been sent to the board.

If you close the software, it is equivalent to waiting for the board to execute the last command, and it will be out of control.

It may grow light the follow up, so it is recommended to power off the hardware first and then turn off the software.
