hi, I’m experiencing this problem with my Ortur Master 2 pro:

[SC7A20:(355) Shock and Movement detected! Check TroubleShooting Section in User Manual.]

Ortur Laser Master 2 Pro Ready!

OLF 152.

[MSG: Flame detector active,Ambient infrared value:4093]

Grbl 1.1f [‘$’ for help]

[MSG:‘$H’|‘$X’ to unlock]

error:9

G-code locked out during alarm or jog state.

I’ve tried updating the firmware from 152 to 191 but after a few hours and many fails I gave up.
