I had an older version (Don’t remember which version) and i was working with my MPCNC + JTech 4W laser.
I saw there is a new version, so I upgraded my version.
Now lightburn is unable to connect to my MPCNC, it writes “waiting for connection”.
The only change was lightburn version.
Any idea what can be the problem?
Something wired happened.
I tried to re-start my computer but it didn’t help.
So i closed the LightBurn and opened repetier-host it was able to connect and control the MPCNC.
I cloed then the repetier-host and re-opened LightBurn and it worked
