    Default Reset program zero at current position using Macro B

    Hi everyone

    I'm learning and messing about with Macro B, and when I run this program on a Fanuc control Series oi-mf I get this error PS0115 Variable no. out of range
    See the error on this line.


    When I typed that line into mdi on a Fanuc 18i control, it worked.

    Please forgive the programming text as it helps me program as I'm just started learning, and I know there are many clever guys on here.

    Are the variables different with that control and if so where could I get them as there is no manual on site

    I know the DPRNT is probably wrong but not bothered at that for the moment.

    I really appreciate any help you can provide.

    Please don't take this as discouragement to learning Macro B. It's a great thing to learn. Wish I'd given it more time over the years. But many times I see it being used to do things that are done much simpler in basic G code ways.

    Continue on with your quest, and sorry I can't help you with your current problem, other then suggesting that at some point, study up on G52. (Local Coordinate System) Whether it completely matches what you're after is beyond me, but from your thread title, I think they're close enough for study.

    Thanks for your comment, but I think you have misunderstood. I could easily program it in G code using either G52 or G10 or G91 G10 if it was for production and to get the job done.

    This is an after-hours project for me to see if I can do it and automate the machine, so you don't have to change the tool radius, the variables will take care of it. I know there a Renishaw cycle that does this, but this is just for fun and to see if I can do it.

    I've just found out the variables are different on this control #5021-#5027 is now #100051-#100057.

    So I'm getting there then il have to rechallenge myself as I want to get good at Macro B

    I know a lot of machine programmers who shy away from the exact thing that you are doing. What they don't understand is the power and freedom it gives you. You now have the power to know if the machine is heading for a crash before it even happens. I was visiting a shop where they wouldn't allow the programmer to program in macro because they didn't understand it. Meanwhile the operators continue to crash the machines. I always enjoyed working with him because he was the smartest man in that shop. It was a pity that they never realized it. You are learning a lost art because so many people rely on CAM & CAD programs to create their programs. When things go wrong they are at a lost because they don't understand how the code works. Keep learning, you are becoming very valuable.

    Hey thanks, Drdos for the encouragement
    I'm a cad/cam engineer by day, but I can see the value in being good at Macro B like you pointed out. Macros are so powerful; I have one for the operators to bore jaws on a lathe all they have to do is alter the variables at the top of the program to get sizes they want
    It keeps the noise away from me so I can do my job

    hello i just looked a bit over this thread

    set program zero at current position
    on an okuma mill/lathe, considering the axis at a random position, i can set the zero by selecting and executing a custom program

    i don't know fanuc, but, to do the same, you need to know the available system variables, and, if they can deliver ( on their own, or combined into a formula )

    cad/cam engineer
    being an engineer doesn't require to master using cad/cam, but at least seing ( ahead ) if the machine&software can deliver a custom solution + many others

    by day
    okey, and by night ?

    all they have to do is alter the variables at the top of the program to get sizes they want
    it works, but it can be speeded up ... using an application, you input data through the gui ( which is way faster then editing the program at the machine, because, many cnc interfaces 'just' work, thus they are just one step ahead from not-working ), program zero, interferences and specs are autocalculated, then the program is loaded into the cnc

    after you create&run a few macros, i guess the next step is no longer what the macro is doing, but shortening the custom programing duration / kindly

    raise by handling inner self conflicts, then even more, by trying not to be alone; emotions is all that truly matters ... war against awareness started more than a lifetime ago

    Have you tried to insert some G53 in between the lines and try to singelblock the program, i know that my machine (0MC) can have some problems, that it executes multiple calculations before it has solved the calculations before so the outcome can be totally wrong. What i understand if it reaches a G53 it needs to bee finished with what it doing before it keeps going in the program.
    I am not sure this is the problem but it can be worth a try

    Hi Deadlykitten,

    I don't understand what you mean in your post, as I wanted help with variables which I have now found out.
    ???

    Edit #1=#4014

    You copy macro from other machine. So if you want to run on your machine you must edit macro
