Mastercam v9 , Fanuc 5t post

[la underdog]

Trying to help a company that lost its programmer. They have Mastercam vs9 and for the short term they need to program an old Mazak M4 with a 5T control. They have the 2 axis lathe post , but I need help editing a new post for an old machine.

What help do you require ?
Also the machine config
- front turret ? # of tools ? tool # range ?
- rear turret ? # of tools ? tool # range ?
what post are we talking about that requires mods?

BTW welcome to the forum

The machine has is vertical 8 in the front, horizontal 6 in the back. The 1st program is the format my current post will put out. The second program is one out of the machine. They are not the same programs, but they show the different formats between what I have vs what I need.

This is the post I am trying to modify. It's actually a lathe/mill post.

I compared this post to the generic post supplied with the installation
It is a lathe post with Caxis
Someone has already edited this post by commenting out (#) some of the format statements ( bad start )

I do not think this is the best post to start with.
*** read all the notes at the top of the post, on how to program for this post ***
note the Misc. Integers section on additional settings

Create some paths and tools, say 3 ops the same, 2 with the same tool ( T1 ) and then 1 with a different tool on the other turrent ( T21 )

Tool setup may be awkward, but how you do it is important for correct code.

Post these paths though various posts ( MPLTL56T.PST may be a good start )
***don't edit posts until you find the closest match to the required NC code***

When you have the closest match, edit the NC code to be correct, noting the change that is needed , deleted, moved, etc

We now copy the post, and rename to say " MPLmazak_M4_5T.PST " , and we modify this post to re-create your modified NC program.

This is a trail and error time, you will start to learn post editting slowly and have lots of errors ( so work in one area and check NC output often ).

Truer words were never spoken. Heed them. It is easy to make too many changes at once, and then not know what to change back. Always make a comment where you make the change. Such as

#ABC(your initials)-deleted *sgcode

Be smarter than I was. Immediately create a file and put all your post solutions that worked in it. Sure makes it easier if you need to make the same corrections to another post a year of two down the road. We had all our v9 posts running great. When converted to X2, many were too old to convert correctly. Some were replaced with generic posts, and then modified...again! Trying to remember what changes you made 5-8 years ago can be difficult for some of us.
