Detect movement, terminate laser engraving! Acceleration fluctuation

I’m consistently getting an error when I start engraving something at speeds beyond 5mm/s that read like:

Starting stream
Layer C00
Detect movement, terminate laser engraving!
Acceleration fluctuation:260
Reset Grbl.

The behavior I’m seeing is the laser barely moves and then immediately stop without achieving anything. This happens 90% of the time, sometime’s it does start but then stops midway:

Also when I have engraved quite slowly it still gives the following error:
Reset while in motion. Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended.

Also when I stop the frozen job the error it gives sometime’s is:
G-code locked out during alarm or jog state.

Here is some example g-code:
; LightBurn 0.9.19
; GRBL device profile, current position
; Bounds: X0 Y0 to X55 Y54
G00 G17 G40 G21 G54
; Cut @ 25 mm/sec, 50% power
; Layer C00
; return to starting pos
G0 X0Y0

Just want to note I have test the machine out sitting on a cement flaw and I still get this error

I was able to fix this by setting $33=1000 for people’s information if other’s have a similar issue

Please note: For those unaware I believe that this is essentially turning off the g-shock sensor by increasing its limit drastically, which is a safety feature. Please keep in mind that this will likely mean that the machine doesn’t have protection of shutting down if it falls or tumbles.

Can some please guide me to resove the below issue .

I recently bought Ortur laser master 2 pro , for the very first trial the machine shook violently and I had to emergency stop it after that I am having trouble in executing any job.

In the second trail it worked for few seconds than stopped . Now it just do homing and we cant even do Framing. Following are errors log.
