The following G and M codes are supported by the Control Interface.

Code	Command	Format	Purpose
F	Feed Speed	F<speed>	Sets the feed rate, or rate of movement of the axes.
G4	Dwell Time	G4 P<milliseconds>	Inserts a delay in milliseconds.
G90	Absolute Coordinates	G90	Sets coordinates to absolute, so that the motion commands are relative to the origin.
G91	Incremental Coordinates	G90	Sets coordinates to incremental so that all motion commands are relative to the previous position.
G92	Set Absolute Origin	G92 X<#> Y<#> Z<#>	Sets the origin that is referenced when in absolute mode.
M0	Program Stop/Pause	M0	Stops the g-code file from being further processed until the operator presses Continue or Start.
M30	End of Data	M30	Marks the end of the file. The rest of the file will not be processed.
M3 or M4	Spindle On	M3 or M4	Starts the spindle.
M5	Spindle Off	M5	Turns the spindle off.
M6	Tool Change	M6 T<#>	Requests the machine change to the specified tool number. It will turn off the spindle and coolant and other required operations when it changes the tool.
M7 or M8	Coolant On	M7 or M8	Turns the coolant flow on.
M9	Coolant Off	M9	Turns the coolant flow off.
M90	Output Off	M90 OUT<#>	Turns the output to the Off or 0 state.
M91	Output On	M91 OUT<#>	Turns the output to the On or 1 state.

Code	Command	Format	Purpose
G0	Rapid Move	G0 X<#> Y<#> Z<#> A<#>	Moves one or more of the axes at the rapid speed, to the specified location. Note that not all axes are required to be specified.
G1	Straight Line	G1 X<#> Y<#> Z<#> A<#>	Moves the specified axes in straight (linear) motion. It will use the requested feedrate, either from the F command or whatever the cut speed has been specified to be. This is a cutting move.
G2	Clockwise Arc	G2 X<#> Y<#> I<#> J<#> or G2 X<#> Z<#> I<#> K<#> or G2 Y<#> Z<#> J<#> K<#>	Moves two axes (XY, XZ or YZ) along the path of an arc in a clockwise direction. The XY specification is the end position, and the IJ specification is the center of the arc.
G3	Couterclockwise Arc	G3 X<#> Y<#> I<#> J<#> or G3 X<#> Z<#> I<#> K<#> or G3 Y<#> Z<#> J<#> K<#>	Moves two axes (XY, XZ or YZ) along the path of an arc in a counterclockwise direction. The XY specification is the end position, and the IJ specification is the center of the arc.
