4.11.4.5 M30: Program End, Cursor Returns to the Start of the Program

M30 command should be placed at the end of the program to indicate that the program ends here. This command stops the program running and spindle rotating (M05), and turns off the coolant (M09). Moreover, the cursor will return to the start (first block) of the program. M30 command is more commonly used to end the program than M02.

Note:

The Cycle Start button on the machine panel can be set to run the program as well, please contact your machine maker for further information.
