This is very helpful. It appears that you’ve already entered a command to shut off the infrared (flame) sensor.

I searched for Shock and Movement Detected and for the particular model of the Laser Engraver.

There are detailed instructions here to shut off the sensor:

Help! Shock and Movement detected! how do I make it stop doing this!

Your firmware, indicated by the OLF number, is newer and the fix should be this.

Years ago, some folks would have the error message show up when they moved the laser engraver to a lighter, slightly more wobbly table and return to working perfectly when on a stable surface.

Please let us know if the physical location of the laser engraver changed between working and not working, and if the above fix resolved the Shock and Movement message.
