The following G and M codes are supported by the Control Interface. Click on the Command name to get more information and examples with the command.

You can find more extensive examples on G-code in the G-code examples page.

Comments

Writing comments in your g-code can be helpful in keeping track of each line. Comments will also let you "comment-out" a line, so that the line is ignored.

To comment out a line, add a % sign to the start of the line.

The TechnoCNC interface will ignore all lines that begin with a asterisk *, open parentheses (, percent %, and forward slash /.

Examples

% This line is ignored.

( This line is ignored.


Setup Commands

Code Command Format Purpose
S Spindle Speed 
S<speed>
 Sets the spindle speed.
F Feed Speed 
F<speed>
 Sets the feed rate, or rate of movement of the axes.
G4 Dwell Time 
G4/seconds OR G4/-seconds (hundredths)
 Inserts a delay in seconds or hundredths of a second.
G90 Absolute Coordinates 
G90
 Sets coordinates to absolute, so that the motion commands are relative to the origin.
G91 Incremental Coordinates 
G91
 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.
