DISK FORMAT: The floppy drive on the Sodick EX21 and Mark 21 control is capable
of using 720KB type 3.5-inch floppies – “2DD” type. Disks formatted for IBM use will
be fine, just be sure to format at 720Kb (not 1.44Mb). If the floppy is a “2HD” type
TAPE CLOSED THE SQUARE KNOCKOUT ON THE LOWER RIGHT OF THE
DISK!
DECIMAL POINTS: The above examples use decimal points in the program, this is not
required but is recommended.
OFFSET VALUE OUTPUT FORMAT: The above examples are assuming the machine
is in 4-digit inch. Please follow the below table. The machine can be placed in 5 digit if
preferred.
4 Digit inch offsets 5 Digit inch offsets Actual amount
H089 H890 .00890
H052 H520 .00520
SPECIAL CODES FOR AWT (Threader equipped)
Cut - Thread wire example
N0100 M03
N0101 T90
N0102 G00 X (value) Y (value)
N0103 T91
G29 code: Use this code to set the present position as wire rethread point (if the wire
breaks). Usually used at the beginning of a program if the T91 code is not there. Also
use this code before tab cut off moves when making punches, as the T91 code
probably was not needed to thread the wire, but a roughing condition will be used for
the tab move.
N0001 G54
N0002 G90 G92 X0 Y0
N0003 G29
N0004 T84
Etc.
G02 G03 “I” or “J” Values: I or J values are incremental from start of arc to the center
point of the arc.
