Laser Master 2 Pro red light flashing, what should I do?

Check your emergency stop button. Twist to release.

  : I have checked the emergency stop. The problem happes as soon as I turn the machine power supply on. I plug the power cable in and as soon as the power from the outlet is turned on, the red light starts flashing ( i tried clicking stop, that doesnt work)

  : Push the E-stop in, then twist sideways to release. The other issue would be that the laser has not made connection to the lightburn program. What com port is showing in use in the DEVICE tab? Mine defaults to COM 12 and my Ortur engravers won’t work unless it is set to COM 3.
