Here are some important notes that you must read before jumping to the detailed commands references.
G0 command, the toolhead will not emit the laser.G0, then G0 can be omitted.G53 and G0 are programmed on the same line, the motion will differ. See the G53 section for more information.G0 [X<pos>] [Y<pos>] [A/B<pos>]
G90
G0 X1 Y-2.3
G90 sections for more information.G1 command must include the feedrate specified by the F parameter.G1, then G1 can be omitted.G53 and G0 are programmed on the same line, the motion will differ. See the G53 section for more information.G1 [F<rate>] [S<power>] [X<pos>] [Y<pos>] [A/B<pos>]
G20/G21).S1000 represents emitting 100% power laser.G90
G1 F1200 X1 Y-2.3
G90 sections for more information.G4 must carry the P parameter, whose value is specified.G4 P<time(sec)>
G4 P0.5 ; Dwell for 1/2 second
G4 P5 ; Dwell for 5 second
G17 command is used to set the current plane as the XY plane.G18 and G19 commands, and usually there is no need to use the G17 command as well.G17
G17
G20
G20 ; set units to inches
G21
G21 ; set units to millimeters
G53 at the beginning of the linear motion commands on the same line, it allows the toolhead to move in the machine coordinate system. What's more, since G53 is not a modal command, it needs to be included on every line where it is required.G53 [G0/G1] [X<pos>] [Y<pos>] [A/B<pos>]
G53 G0 X10 Y-20

G55
G56
G57
G58
G59
G54
G90
G90 ; Set all axes to absolute
G91
G91 ; Set all axes to relative
G92 command is only used to set the position and does not generate actual movement.G92.1, the offset between the currently active coordinate system and the machine coordinate system can be reset to 0.G54 - G59.G92 [X<pos>] [Y<pos>] [A/B<pos>]
G92 X1 Y2
G92.1
M3/M4 are both used to set the laser power.
M3 is used to set a constant power. That is, in M3 mode, the machine will not change the laser power during motion.M4 is used to set a variable power. That is, in M4 mode, the machine will dynamically adjust the laser power based on the movement speed of the toolhead during motion, in pursuit of better and smoother laser engraving effects.M3/M4 command is used without parameters, the toolhead will emit laser at the power configured most recently.M3 [S]
M4 [S]
S0 represents turning off the laser, S1000 represents emitting 100% power laser.M3 S1000

M8 ; turn on the coolant/air assist
M9 ; turn off the coolant/air assist
