Laser head moving but not lasering

Hi, suddenly after the last firmware upgrade my laser head is just moving around the path without burning anything, please advise

Do you have an enclosure? If you do the laser stops “lasering” if it thinks the door is open. This can happen if it’s slightly open or the sensor has moved.

Thanks Stewl, I don’t have the enclosure yet, it was working with same settings just before the firmware, noting that the issue is only if I print through Luban but if I send the file over wifi it works fine
