Need Help!- post edit

[Mark and Poco]

Does anyone know how to change the generic fanuc post to output all its possitions in a no decimal 4 place trailing condition. I found the explanation in the post, just cant get it to do it.

example


X 1.2345 and I need it to read x12345

any help would be great.
The note I found is on page 19 under format statements
I am trying to get it to post with format statement 16
fs2 16 0 4 0 4t #No decimal, absolute, 4 trailing. Any help would be greatly appericiated

Which version of Mastercam,would help.

[Mark and Poco]

Sorry about that. Version is X4 (14) Thanks again everyone. You are the best.

You need to edit the post with the VBScript (under Settings -drop down to VBScript). Make sure you keep a copy of your post (backup), open post , go down about 1/2 way and you will see section that you have to change. I suggest you print the post and markup as you change to keep on track and you will see all items that you can change...do one at a time and test so you can put back if wrong.

any chance of doing a cut and past for me to show me where it is. I'm still lost. Thanks again.

If you want to output x, y & z in format 16 or any other, change to corresponding format number on lines 677, 678 and 679 (from "fmt X 2 xabs" to "fmt X 16 xabs" etc.), few lines below where you found "fs2 16 0 4 0 4t".

Alternatively, you could just change "fs2 2 0.4 0.3" to "fs2 2 0.4 03".

I'm just a rookie in post editing so please check thoroughly before sending to machine.
Also, this is for mcx5, I don't have x4 right now. If this doesn't work I can try to find x4 somewhere.

I'll see if I can explain what controls what

the fs or fs2 statements are how the post makes a value available for placing with a letter address

Any value in mastercam could have 500 digits after the decimal place ( or have no decimal point at all ), the format statements are used to "chop" these valuse down to a usable size, and can be used in more that one area. fs2 1 "chops" everything down to 7 decimal places for inch, or 6 for metric.... the "lost" numbers are still there, but not available to you

Untrained, you could end up with a tool number wth a decimal point, or a G code with 2 extra zeros.

fmt  A  14  cout_i      #C axis position
fmt  A  4   indx_out    #Index position

Take for example, fs2 4 1 0 1 0 #Integer, not leading, it is used for the T, D, H, etc. If you alter format statement #4, things will get a little messed up...don't you agree

Solution
create NEW format statements, so you know they arn't used elsewhere, ie
fs2 22 4 3 #no Decimal, absolute, 4/3 place
fs2 23 4 3d #no Decimal, delta, 4/3 place

absolute for the XYZ, incremental for the IKJ ( if needed )

you, at this stage, have not modified the post as this is added, but not linked to any fmt strings

now alter the
fmt X 2 xabs #X position output
to
fmt X 22 xabs #X position output

save and check the NC code, you now only need to play with the fs2 22 line to get it correct, once done, change the other addresses that need altering.

Have you noticed the incremental ones ( fs2 3 ) ??
- that is the "delta" format that would also need applying.

Happy posting

Thanks that did it. I just have a few more to fix, but nothing a little hand editing won't fix. Your info was spot on.
