Light burn laser won't go on and contour

I’m running an OMtech 50w fiber model and running the latest version of lightburn1.4.01. I successfully tested my first metal piece and then swapped the piece for another one to run another job and pressed start. The laser wouldn’t fire. and when I frame the contour frame won’t show up and the laser won’t fire again. What am I missing?

ok contour will go on now but the laser isn’t firing. Any suggestions?

Did you change focus when you changed materials? Focus is very critical with these…

:smile_cat:

yes the focus was out of range so I adjusted it and now its working. A couple of times the laser wouldn’t detect or say no devices connected in lightburn so not sure what that was about.
