    Lathe repeat cycle

    Hi all, very new to this, Have an ORAC that I have had to convert because like me it is old and it lost its tiny little mind, I forgot EPROMS don't hold on for ever.
    With the ORAC I used G73 start do loop and G06 end do loop, I now see there is G75 for pattern repeat in CNC TNG, does the TODO in the G-Code reference guide mean it is not implemented yet?
    Is there any other way of creating a repeat cycle without creating multiple copies of the same code?
    Thanks, Chris

    Yes.

    Menu > Machine > Start Options > Start Loop ...

    Thanks Martin
    Tried it, it is very limited, repeats the whole program, so I will have to break the program down into blocks and run 1 block at a time.

    Make subprecedure containing your g-code. Then execute subprocedure multiple times in a loop.
