Wait till complete

Is there a function or something to wait till "something" is complete before resuming movement.

I am building a press machine of sorts and it will move to an x,y position then I will use the spindle on/off to trigger a pneumatic cylinder. I can just use a delay of "X" number of seconds but didn't know if there was a more "efficient" way to have the next motion movement wait till this cylinder has completed its stroke..

Maybe like a "feedhold" button/function or something where my cylinder can hold that button down till its complete then release the button.

A G4 delay will work but that could slow the operation down some because I must ensure I have sufficient time on the delay for any variations in the cylinder stroke cycle time..

I think the G4 is the only way to do this. I am not sure why it would not be efficient. If you know how long the pneumatic operation takes then just use g4 + some fudge room and it should be pretty efficient?

Thanks,
I will handle it with a g4 and just try to make the delay as accurate as possible..

Its the having to build in "fudge room" that makes it less efficient.
