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

Setup Commands

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.

Routing Commands

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.

Drill Cycle Commands

Code Command Format Purpose
G80 Drilling Cycle Off
G80
Turns a drill cycle off.
