Laser turns off after one pass but motor continues running

I am trying to cut a multi piece design. LB is set to do four passes. It does four paths over the first piece and moves to the second. Then the laser turns off. It still is moving in the right path, but with the laser off. Any thoughts?

Might be a firmware error on the “laser off” command
Tht once issued will not allow laser to turn back on again

Could you make sure your machine isin latest firmware?
also that your machine is using GRBL (top of the list) as controller?
