Ortur laser moving but not firing


I just got my Ortur laser master 1. I installed Lightburn on my Mac.

I got the laser to move but not to fire. I got it to fire once but not anymore.

After this I installed the new firmware from a windows computer and made my first engraving with Grbl from this same pc. All fine there.

But I would like to use my Mac with Lightburn. any suggestions on what I’m missing here?

This is possibly your issue. What do you have set for your $30 in firmware? These numbers need to match.


Thank you so much, that solved the problem. This is now set to 1000.
