Post Processor Editing

[Malish]

I have read on the fourms that some of you edit the post processors. Is there any kind of documention on how to do it? I have not found anything in the help files about it.

What CAM software are you using? I use SmartCAM and BobCAD, and for both of those you can download literature from their websites on editing post processors. With BobCAD, they have a pretty extensive .pdf on it.

My suggestion is check with whoever makes your software.

I just upgraded to BoBcad V22

Thanks for the links!

Only bad thing is that I get and error when I try to lunch the MillEditPost.exe

"MillEditPost MFC Application has encountered a problem and needs to close. We are sorry for the inconvenience."

Ouch! I am running WindowsXP at the shop and Vista at home. They both run ok on my OS's. Not sure I can help ya out there

You need to go to the bobcad website and redownload the millpostedit file. Click here http://s229444871.onlinehome.us/bobc...dsupport/posts
Then read the instructions for downloading and installing the file. This should get you up and running again.

Great to hear it!

Ok, I got the post editor to work now I have one small problem with the cose I am generating. The Haas mills allow the use of the M97 subroutines instead of the using the M98 sub program call (M97 will put the subroutine right after the main program in the same file, while M98 creates an entire new program to call). I perfer using the M97 as I like seeing the entire thing in the same program. I changed the subprogram call to M97, but I need to have the prgram of the subrotuine be N1000 (SUBPROGRAM OF O173) instead of the O1000 (SUBPROGRAM OF O173) that it is creating. Is this possible to do?


Below is the program I created...

It also has to put the % sign after the subprogram.

I also have to do some tinkering with some of my programs after they are posted. I find it easiest just to go into the program at the editor and change what I need to change before sending it to the machine.

I am trying to make this out. So there is not really a sub program number but a line number instead? Wierd from what I have seen on other controllers. I see how it works...just never saw that done before.

I am not sure without some toying around in the post how to make this work (if at all). This may also require a special post from Bobcad.

Did you know that you have more options in the post than the post editor program shows you? You can go into the post directory and edit the post using notepad. Then you may see something that could help.
