    please, what is the purpose of dry run without machine lock ?

    hello please, what is the purpose of dry run without machine lock ( lathe ) ?

    about mills, i was told that there is something possible, like starting a program in dry-run while having z axis raised, then, when needed, z axis and speed, both will go back to normal

    so i thought that, also on lathes, i can start a program like this, then disable this mode, and continue at normal speed, but once i disable it, also the program resets; i guess it is there in order to proof a program, but i am not sure

    i use dry-run and lock in order to check syntax errors inside a program, or to find the restart number; i never used only one, but always both, and it kicked me a few seconds ago, that there may be something that i don't know / kindly

    Why....?
    Haven't you worked out a faster method ( no dry run or m/c lock)

    To check syntax.... fastest method is to restart to a N number that doesn't exist
    Okuma would step through each line, parsing it as it goes.
    It also would display the graphics as it processes.
    Worked well on the OSP 5000 & 7000s, a little more involved on the P series ( this is stirring up the grey matter ).

    hy superman yup, good idea to restart at a non-existing N

    i have a lot of wrong restarts, but it never kicked me to use that as a proof method

    Mill will allow you to go in and out of dry run without causing reset. It will use the jog feed rate to control how fast it runs but will ignore programmed feed rate in favor of jog “rate”. Lathe will run through the program at a parameter set 200 ipm and will ignore the ipr feed rate. Feed override will allow slowing and speed up but turning dry run off will reset the program. On either machine type it is not intended for anything other than dry running through the program like the switch says.

    I also believe that you can use restart E as in end to check for syntax errors in addition to what Superman says.
