M30 End Program (Lathes & Mills)
Okuma OSP M-code · Mill and lathe
M30 is considered the standard program-end code, and will return execution to the top of the program. Most controls also still support the original program-end code, M02, usually by treating it as equivalent to M30.
Machine builders set many M codes, and they change by model and options. Check the M code list for your machine.
