G04: Dwell
Format: G04X__;
The G04 command causes a pause in operation for the amount of time specified by the X or P
value.
EXAMPLE: G04X1.5; This command will produce a dwell of 1.5 sec. and could be used to allow
G09: Exact Stop Check
The G09 command will prevent the rounding of corners which may occur at high feedrates. The
command insures that a block of axial movement is fully completed before continuing to the
next block.
EXAMPLE:
Because there is a hesitation after a movement with exact stop check, some burning of sharp corners may occur on
thicker materials. If such burning occurs there are methods which may be used to eliminate this phenomenon:
- Power Ramping: Two sets of cut conditions are created. The first of which is at a high
power and feedrate for the majority of cutting and the second is at a low power and feedrate for the cutting of
corners or intricate geometry's.
- Corner Looping: The corner is passed and a circular loop is made to bring the cutting path across the actual point of
the corner.
G28: Reference Point Return
The G28 command can be used to return any axis to its HOME position at rapid travel speed. It is
commonly used at the end of a program to return all axes to their respective HOME positions so
that parts may be removed from the cutting table and a new sheet of material can be added.
