in the circle center and arc direction defined by the instruction, X axis and Z axis move
along the arc from the start point at the same time; if the coordinates of X axis or Z axis
are same to the end point, X axis or Z axis stops motion, and the axis (Z axis or X axis)
continues to move to the end point, as shown in Fig. 3-4-4 below
End point Start point

3.2.4. Pause instruction G04
Instruction format: G04 P__;
Or G04 X__ ;
Instruction function: every axis stops motion, do not change current G instruction mode
and maintained data and state, delay for specified time, and then execute next
block. The delay time is specified with instruction word P__(unit: ms), X__(unit:
sec). G04 is non-modal G instruction.
G04 P1000 delay 1000ms = 1sec
G04 X1 delay 1sec
3.2.5. Return to mechanical home G28
Instruction format: G28 X(U)_ Z(W)_;
Instruction function: from the start point, arrive at the center point specified by X(U), Z(W)
at the fast moving speed and then return to the mechanical home at the same time.
G28 is non-modal G instruction.
One or both instruction addresses X(U) and Z(W) can be omitted; see the table below for
details
Instruction Function
G28 X(U)_
X axis returns to mechanical home, Z axis
stays at the original position
G28 Z(W)_
Z axis returns to mechanical home, X axis
stays at the original position
G28
Two axes stay at original position, and
continue to execute next block
G28 X(U) Z(W)
X and Z axis return to mechanical home
