The flame Alarm turn on for no reason. Sometimes I use the laser for multiple tasks and nothing happens and sometimes the flame alarm turn on directly when I turn on the machine or in the middle of engraving.
I have a Ortur laser master 2 pro with Lightburn and a Macbook air.
Itβs likely not for no reason. It could be triggering a false alarm due to ambient light or something else because the sensor is too sensitive. Note that in the latest firmware that the default for the flame sensor has been disabled ($261=0). You could experiment with lower values for this if you want to keep it on for safety purposes.
In either case, suggest you upgrade to the latest firmware as it addresses some additional issues with the firmware.
