I have been using the laser master 3 on and off since it first came out and have always had small connectivity issues where it would disconnect and i would have to reconnect, however after a few months of not using it now it will not connect or show up at all in lightburn. the image attached is what comes up in the console. i have tried selecting other COM locations and all will come back with the error message of “Port failed to open - already in use?”. i did notice the other forum answers mentioned to download a file and select it as the unit. i tried that and it did not work either.
Bump…
Could really use the help to get this back up and running!
See:
Hopefully it can help with the connection issues your having.
I appreciate the help!
I’ll give this a run through later today to see if any of it can help!
I did give a quick glance at the GRBL error codes and didn’t see any for the “error:G0” that is popping up. But hopefully it may just be a connection issue that can easily be solved
