Hello guys, can someone help me?
My machine doesn’t work, erro flame protection triggered but I use the GRBL software. Anyone know how to fix this??
Hi
The flame sensor has either an on off or a value setting that you can adjust.
I dont know much more than that but you will probably find more info using ‘Topic Search’ or Lightburn Doc’s.
I see nothing in Doc’s about it but will check Post Topics.
Have a read of that and maybe also post the console messages so someone might identify the issue.

The flame protection or alarm 3 is triggered
The flame sensor can be easily triggered. When the flame sensor is triggered, the LightBurn console will display an alarm 3. This may be due to ignition during use, strong light exposure, settings issues, short circuit, or damage. Please refer to the following settings for inspection: Avoid open flames during the engraving process. If an open flame occurs, please reduce the laser power. Place the engraving machine in a normal indoor environment, avoiding direct exposure to strong lights such as flashlights or sunlight. Adjust the flame trigger threshold. First, run the LightBurn or LaserGrbl software, connect the engraving machine to the PC via USB, and enter $42=1300 in the control command panel and press Enter to lower the trigger threshold. If it still triggers, you can continue to reduce the $42 threshold and send it. If the flame sensor is triggered at the start of engraving, it may be due to a short circuit between the sensor’s metal pins and the metal casing. Please manually adjust the position of the flame sensor behind the control box to prevent contact between the metal pins and the casing (the flame sensor is a black cylindrical probe located at the back of the RAY5 control box); if ineffective, you can send the command $38=0 in the LightBurn or LaserGrbl console to disable the flame sensor function (to 30 enable it again, send the command $38=1)
