Rapid
positioning
Switch to rapid linear motion mode (seek). Used to get
the tool somewhere quickly without cutting --- moves the
machine as quickly as possible along each axis --- an axis
which needs less movement will finish before the others,
so one cannot count on the movement being a straight
line.

1
Linear
interpolation
Switch to linear motion at the current feed rate. Used to
cut a straight line --- the interpreter will determine the
acceleration needed along each axis to ensure direct
movement from the original to the destination point at no
more than the current Feed rate (F see below).

2
Circular
interpolation,
clockwise
Switch to clockwise arc mode. The interpreter will cut an
arc or circle from the current position to the destination
using the specified radius (R) or center (IJK location) at
the current Feed rate (F see below) in the plane selected
by G17/18/19 (see below).

Circular
interpolation,

e
Switch to anti-clockwise arc mode. Corollary to G02
above.

Dwell (pause)
This should probably be calculated to be only one or two spindle rotations for
best efficiency. Dwell time is expressed using a parameter (may be X, U, or P)
which determines the time unit (seconds, milliseconds, &c.) P, for seconds, is
supported and used by Grbl., typically X and U express the duration in
milliseconds.

Set Work
Coordinate
Origin (and
resultant
Offsets)
Coordinate system origin setting. This setting is
persistent and expects the user to follow good practices
and not manually move the machine, instead only using
jogging commands via the interface or a pendant which
works through the control system, or to have and use
homing switches. Examples:
•
G10 P1 L20 --- (which is the equivalent of G92 X0 Y0 Z0) for work co-ordinate
system G54 (#P1)(#P2--#P6 are G55--G59 respectively)
•
G10 Px L2 (by automatically setting the specified axes from the machine
position data) to (re)set the persistent work coordinate offsets.

Select the XZ

Select the YZ
plane (for arcs)

G20
After this, units
will be in inches
Best practice: do this at the start of a program and
nowhere else. The usual minimum increment in G20 is
one ten-thousandth of an inch (0.0001").
