Hurco BMC 40 Post Processor

[jwmodel]

I have a 1988 Hurco BMC 40 and Im having problems with the post processor that fusion supplies. I have used the post processor (Hurco 3D and 2569_hurco.cps). The first post processor I had no luck with it and the second one I had to modify a few things in the program in a word document to make it work somewhat. Is there any way anyone can help me out with this issue and I've attached a sample of what Fusion is sending out vs an old program the former owners of the mill was able to use with no issues.

As you have a modified copy of the Post Processor can you please upload it here as no one has an idea of what modifications you have already made, thank you 🙂

[jwmodel]

Here is the post processor I was using that is close. I did not edit the post processor I just edited the program in a Notepad. Let me know what you can do. Thanks

Hi @jwmodel 

have you tried to change the value of a post property, "Use ISNC or BNC mode"?

You should start by trying that.

By default Hurco machine can run code in one of two mode.

But the older machine like the BMC were only running in BNC mode.

Try setting this property to false

Regards.

You will have to excuse my lack of knowledge on this but do you change that in the post processor or on the machine? If so in the post processor is there any chance that you would be able to change that and send it over to me?

Hi @jwmodel 

This is not very complicated, you just had to edit the post using a text editor.

(Notepad, notepad++... but not Word and alike)

Then change this code

  optionalStop: true, // optional stop
  isnc: true, // specifies the mode ISNC (ISO NC mode) or BNC (Basic NC mode)
  separateWordsWithSpace: true, // specifies that the words should be separated with a white space

into that code

  optionalStop: true, // optional stop
  isnc: false, // specifies the mode ISNC (ISO NC mode) or BNC (Basic NC mode)
  separateWordsWithSpace: true, // specifies that the words should be separated with a white space

Or else, just changing it once at posting time, to test, then edit the post if the code run successfully.

Cheers

With the changes of the post processor I am accruing errors on the machine. I have attached a couple of pictures of the errors I'm having. Please advise if there's anything we can do about this.

Sorry, ignore my last reply but with the changes of the post processor I am accruing errors on the machine. I have attached a couple of pictures of the errors I'm having. Please advise if there's anything we can do about this.

Thing it dose like.

• Having no program name like (1010)
• Putting the federate before the z axis move 
• Having just a E at the end of program with ne N# infront of it

Hi @jwmodel 

this can be done, but we first be sure what mode the machine is running in.

Because your next program may use a function not used in this one, and generate another error.

I was wrong, as the ultimax controller may be set in Basic (BNC), or Standard (ISNC) mode.

But it was frequently set to used BNC.

Take a look at your manual, it must be explained somewhere in the user manual.

Check the mode, and tell us, please.

Regards.

It (ISNC mode)

[jwmodel]

Sorry meant (BNC Mode) not (ISNC Mode)

[jwmodel]

Didn’t know if you got my reply yesterday about it being (BNC Mode) not (ISNC Mode) on my Hurco. Let me know what you come up with thanks

Hi @jwmodel 

So, here is the modification I am suggesting to your post processor.
Open it with a text editor, like notepad.

In the beginning of the file, look for the properties definitions, and change the ones highlighted.

As we don't need the lines numbers, and the machine is running in BNC mode.

Then look for the onOpen function, and we will have to delete some lines at the top of the function:

Delete all the lines in the framed section.

This will remove the program number.

We will then move to the end of the post processor at the very bottom, to remove the M61, and the G69.

After deleting this line, we will delete another one below:

For the E at the end, I think it was the line number that was inappropriate.

Regards.
