Code
Function Preread disable

Format
[Explanation]
[Program Example]
M100
Executing this command does not execute preread on the G-code (Motion programs).
After completion of motion up to the preceding block, the next block is processed.
N10 G01 X10. F10. ;
M100 ;
IF [#2000 EQ150] GOTO20 ;
N15 G01 Y10. ;
N20 G01 X0. Y0. ;

(Note) : When M100 is executed, constant-speed positioning does not continue from
N10 to N15 or from N10 to N20 and a deceleration stop is made once after
execution of N10.
Preread is not executed on the G-code (Motion program).
Since M100 exists in the next block, a
change in #2000 during execution of the
command on this line is reflected on the
IF statement below.
