My laser worked on Lightburn, but I must have changed a setting because it won’t work now. I searched the previous posts and cannot find an answer. My Grbl settings are as follows:
I jogged the machine and Z-Axis worked, then when I tried X and Y axes , I got this:
Waiting for connection…
Waiting for connection…
Port opened, waiting for response.
Grbl 1.1g [’$’ for help]

[MSG:’$H’|’$X’ to unlock]

ok

I had to restart the program after the X and Y axis failures, and I got the following for $$:
Waiting for connection…

I have also attached screen shots of any settings. I am running Windows 10 and the latest version of LightBurn. Please let me know if you need any additional info. Thank you for help.
