A little bit of G code help please!

[njhussey]

As someone has said above, an M0 is the best way to pause the program.

An example would be...
(this is based on fanuc/has g code but the format will be the same)

...
G83 Z-10 R3. Q3. G99 (drilling cycle)
X4. Y6. (hole position 1)
X44. Y46. (hole position 2)
G0 Z50. (rapid away from job in z)
X0. Y0. (rapid to home/change position)
M0 (program stop)
... Continue program

The M0 will pause the program until you press the green cycle start button again.

Thanks James, I'll "air cut" a small program with this in and try M0! The list of G-code commands I have just says program stop and nothing about a re-start so I didn't want to use this, certainly not in anger.
