bought a new diode and ramp board. when i plug usb in the computer recognizes the machine. when plug in usb and the machine is on i get a burn of about 2 seconds. the machine does not operate on any commands. any ideas or suggestions greatfully accepted
If my memory is working, seems to me that machine needed an upgrade to a newer version of grbl. I thought I saw this on this site, but couldn’t locate.
I don’t think Benbox is compatible with lightburn. 
Here’s a video on changing the firmware, if you chose that path.
Search on this “Eleksmaker laser firmware upgrade site:https://forum.lightburnsoftware.com”
There quite a list on the LightBurn site.
