Three days back, start my problems with Shock and Movement detected! I don’t know how to fix it. I tried some advice from forum, but nothing help.
[SC7A20:(425) Shock and Movement detected! Check TroubleShooting Section in User Manual.]
Ortur Laser Master 2 Pro S2 Ready!
[MSG: Warning: Flame Sensor Disabled by User OverRide]
[MSG: Flame detector active,Ambient infrared value:0]
Grbl 1.1f [’$’ for help]

I had this problem too, just adding what worked for me, in case it helps anyone else struggling with the same.
I had to change the $262 value to change the G-shock threshold.
I ended up disabling mine entirely by setting $262=0. This means I will not get an alarm if the laser cutter falls, but I never leave it unattended while in use, so this is fine for me, but please take the time to consider this as you are disabling a safety feature. Please note, too, this fix only works for firmware 1.78 (or, presumably, later), so you might need to update your firmware first.
If you wish to disable your sensor entirely, go to the console window in LightBurn (while you are connected to your Ortur) and type $262=0 and hit enter.
If you’re having trouble with this value ‘sticking’ (for example you get this error again after re-starting/resetting your machine, or after changing firmware), you can also add this command to the start GCode for your laser (Edit>Device Settings>GCode>type it into the ‘StartGCode’ box>Hit OK). This will mean that it will turn off the sensor before every job that you run, so it’s sort of a backup. Side note, but it’s also handy to add $H to this box too, to home your machine before each cut, in case you haven’t got it in there already.
You also don’t have to entirely disable the shock sensor, you can just change the threshold value, if you wish (this should work in earlier versions of the firmware, too). You can check the current threshold value by typing $$ into the console in LightBurn (which will give you a list of all current values for all settings for your connected machine). From there you can set it to a different value by typing $262=[number] (e.g $262=500 to set it to 500).
Here’s a list of all the commands for ortur and their default values (I had a hard time finding these, so I’m posting it here in case it’s handy for others!).
