I noticed that every move instruction has a speed argument which is always the same. e.g.:

;
G28; home all axes
G21; Set units to millimeters
G90; Use absolute coordinates
G92; Coordinate Offset
G00 X0.0 Y0.0
M03
G01 X0.1 Y0.0 F288
M05
G00 X0.4 Y0.0
M03
G01 X0.6 Y0.0 F288
M05
G00 X0.8 Y0.0
M03
G01 X0.9 Y0.0 F288
M05
G00 X1.1 Y0.0
M03
G01 X1.1 Y0.0 F288
M05
...

If the speed is always the same it can be set once at the beginning

e.g.

Not only saves this disk space (uhm..., who cares nowerdays ), it saves also a lot of unneeded serial communication and processing on the GBRL interpreter.

The option to set the spindle speed for G00 is not needed. We only want to control G01 (when the laser is on!). G00 is already been set in the configurations of the GRBL.
