Can be specified with other G-Codes on any line. XYZW values from the current line forward are read as
absolute coordinates. IJ values are always relative to the current XY position, not absolute positions
regardless of G90/G91 mode.
G91
Relative Mode
Can be specified with other G-Codes on any line. XYZW values from the current line forward are read as
relative movements from the current position.
G92
Set Local Coordinates - G92 X# Y# Z# W#
Used to specify a new coordinate system for running absolute mode programs. Use G92 alone to restore the
Machine Coordinates. G92 X0 Y0 Z0 W0 sets the current position to zero. G92 then restores the Machine
Coordinates values.

in

G92.1
Shift MZ Coordinates - G92.1 X# Y# Z# W#
Similar to G92 except that the coordinate system produced shifts Machine Zero by the amount specified. This
is useful since a given local coordinate system can be set without positioning the head to a certain position
first. G92 X10 Y10 sets the absolute position X10 Y10 to X0 Y0 in local coordinates. G92.1 may also be used
to restore a single axis to absolute coordinates. G92.1 X0 leaves YZW local coordinates but sets X back to
absolute coordinates.
G92.2
Shift LZ Coordinates - G92.2 X# Y# Z# W#
Similar to G92.1 except that the coordinate system shift is added to the current local coordinates instead of
replacing them. This is useful for “jogging” a local position. If the Z head has been set for running a G90 mode
file but then needs to set to cut .010” deeper, G92.2 Z-.01 will accomplish this with a single command. Can be
useful as a macro.
G92.3
Stores and Restores G92 values
Allows the user to switch back and forth between local and absolute coordinates. Use the G92.3 command
without any parameters or axis characters. If G92 positions are set on any axis then they will be stored and
cleared. The next G92.3 call will restore the previous G92 values even if they have been cleared by using
G92.
G93
Inverse Time Feed Mode
In inverse time feed rate mode, an F word means the move should be completed in [one divided by F
number] minutes. For example, if the F number is 2.0, the move should be completed in half a minute. When
the inverse time feed rate mode is active, an F word must appear on every line which has a G1 motion, and
an F word on a line that does not have G1 is ignored. Being in inverse time feed rate mode does not affect
G0 motions. It is an error if: inverse time feed rate mode is active and a line with G1 does not have an F word.
G94
Cancels the Inverse Time Feed Mode
Turns off the Inverse Time Feed Mode.
