I'm want to add subprograms to my post processor.

As the supplied post didn't support subprograms, I've started to change the standard MPFAN post to suit. This has worked very well so far but I'm having to move the subprograms from the end of the G code program upto the start of the program manualy.
I would really like to change this to it automaticly in the post.

Any help would be greatly appriated

Cheers

Chris

Update

I think I've found the code that puts the subprograms in, well if I move MERGEAUX up a couple of lines i.e. above line n, "M02", e. Then the subprograms are placed above the line containing M02 but when moving MERGEAUX so it is just below the program no. i.e. below line *progno, e. The subprograms dissapear totaly.

Thanks

Chris

Still can't do it.

Someone help please even if you just tell me it is not possible.

Hi Chris, for sure that is possible. Mastercam has a great handling with subprogs. But in order to define them into your post, it´s very complicated. It depends on a lot of variables and settings inside the post. The answer for you question is not so simple, not even short. but yes, is possible to get subprogs in Mastercam (And they works perfectly when proper configured in the post), but is complicated to define them also. Get in touch with your dealer and ask for him about the MP Guide, available in CD-ROM.

Thanks for the reply, I'll look out for the CD.

Just thought someone would be using subprograms on a brigdeport with there very limited memory and there been so many of them around.

Cheers

It would be easier to start with a post that already supports subprograms.
Then modify it to suit your machine and controller.
I'm pretty sure the Fadal post supports subprograms as you describe them.

[Mike Mattera]

If your using a current MPFan (V9 & up) it already supports subs. It's all in what you pick on the Parameter page, when your doing your toolpath.

Contour: Pick Depth Cuts and check the Subs box.

If your doing a toolpath Transformation. Same thing. Look for the Subs check box.

You shouldn't have to modify the post to get subs. You might need to modify it for a particular format, but it should be there already.

Thanks for the comments even though most of you got the wrong end off the stick, I do still appreciate the help.

A big thanks to ObrienDave thats exactly what I was after, I just copied loads of that post into mine not really sure which bit made it work but it does so I'm happy.

This is what I wanted to get (simple program milling a square a few times for a example)

Has anyone used sub-programs to send the machine to it's index position? I want to program a vtl where I can use different subprograms for the index position for different jobs. What is the format like and how does it work?
Thanks.
