Here is a list of supported commands for G-code import.  Again, the system is not actually moving per the G-code, but actually interrupting the code (drawing it) then sending it to the LSM as a 2D graphic.  For example G0 will designate the start of the next line to be drawn, followed by G1 designating the end of that line.  Syntax would be similar to most other G-code.  Feed rate, power, PPI and motion limits are all set by the LSM using the pen colors and the laser processing “system settings”.

T (change tool), with the parameter being used as a color value from 0 to 15, matching standard ULS pen colors.
G0, G61, G61.1 - rapid move
G1 - linear move
G2 - clockwise arc
G3 - counterclockwise arc
G20 - units/inches
G21 - units/mm
81-89 - Drill
G90 - Set absolute distance mode
G91 - Set incremental distance mode
G90.1 - Set absolute arcs mode
G91.1 - Set incremental arcs mode
G92 - Change origin
G92.1, G92.2, G92.3 - Hard reset origin
