bar puller

[cell13]

I am trying to post a program with bar puller. But not getting correct code. If I take an old program with good bar puller code - delete all operations and geometry, re name file,

re-create geometry and toolpaths and run post I will get good code. I have checked file settings and as far as I can tell I am using the same files for both programs.

On converted program I do not add a bar puller operation, I just do a cutoff ooperation and it posts ok. On new program when I try to add a bar pull operation I get a

warning "Current post-processor does not support toolpaths generated by this function."

I would ask the programmer who made the original program (ya think?) but he is no longer here, so I have to work this out by myself.

Is there a different post he has hidden somewhere? Probably not, I just haven't the experience with lathes that I should have.

Any help will be appreciated.

Thanks (I an only an egg)

What Machine? They all like something different.

To keep it simple, this is what I do.

Go to manual entry.

write a bar puller pgm by itself. (one that works).

Save as a file. Look at the bottom of the manual entry box.

 

Now every time you need it, add the file to the pgm and hand edit the x and z positions as needed. ( you can do that at the machine if needed)

Thanks Machineguy,

Machine is a Haas ST30Y.

I found it in Lathe Cutoff - Toolpath Parameters - Misc. Values, turn off auto set to post values, turn on add bar pull to partoff and turn on parts catcher(Integers), Add distance, Z position and feed rates (Reals).

So easy I couldn't see it.
