Is it possible to loop a g-code program?

[sul1]

I need help.
I have a Robodrill with a fanuc 16i controller and pallet changer.
Is there a command to loop the program back to the top and keep running the program without stopping?
I'm trying to get it so all I need to do is load the extra pallet and hit the pallet ready button and walk away.
I don't want to wait for the program to finish and have to hit the start button as well.

Is this possible?

Any advice would be greatly appreciated.

Thanks

On my bar-fed lathe, if I program an M30 at the end of program, I have to press cycle start every time, so instead, I program an M99 before the M30. If I get really daring, I'll point it to the line I want to restart at, like M99P1 to restart at N1. M99 is not always an end of sub/return to main code. Sometimes it's a branch (GOTO) code. Come to think of it, I could even use a GOTO command, but I'm used to M99

try this at the end of your prog
/M30
M99

with block skip on machine will run continously
with block skip off machine will stop at the M30
also you can try setting the prog calls in the pallet setting page and all you have to push the pallet ready button . we run all 12 of our Robs that way

I tried the M99 by itself on the line before M30, but with no luck.
I'll try directing it to the first line.
Thanks for the tip.
When you use a GOTO command do you also use P1 to direct it to N1?

IIRC, GOTO 1 is the syntax.
