Problem with connection of lightburn to my neje max4 laser

my problem is that up until recently i have had no issue connecting to lightburn, but recently i have no communication, i just keep getting the the waiting for connection on the ligthburn console, my neje software will connect just fine.

Are you on correct com port, and with no other software connected to laser?

with the update to my software , i am unable to find the laser port settings

currently running 1.4.05 firmware

Try going to file > open prefs folder and pick one before update.

i went back to october, i am now getting port failed to open -already in use on the console tab

Usually means something else is on that port.

my software is not giving me the option to change the port

I would say some other software is currently on that port.

so i got the port to establish, now in my console i cannot get the machine to cut the geometry that i have selected

my software is not showing my machine profile
