Longeray 5 false flame alert

Whilst burning a picture the laser stopped working with a message saying flame alert. There were no flames, or burning of any description.
Please help as I am new to laser engraving.
Cheers, Gareth

Are you near a bright light or getting direct sunlight? If so, some of these sensors can get a false positive alarm under those conditions. Your laser may have a way to adjust the sensitivity or turn off the alarm entirely although that negates the potential safety aspect of the machine.

Or if you could shield or otherwise move the machine that could also work.

Hi, thanks for your reply. Yes the machine is in front of a large window and it was quite sunny today. So I will try it next time with a blind or something over the window.
Cheers, Gareth
