Im altering a 5 axis post at the moment, and come across a small problem. I seem to be unable to output any comments other than 0.

Try a search for manual entry, this has been talked about a lot in the past.

Where are your comments coming from?

[Rob_Bish]

From the comment box in toolpath paramters.

A couple of questions.

 

What post are you using?

 

Are you saying the post will output a 0 in the comment?

had a *comment$ output 0. my mistake.

 

Think I have sorted it. I was using numbers in the comment box such as 11111. When using a letter with a number no problems comment comes out where i expected it, and when using just letters no problems. Dont understand why I cant use just numbers though.

Me neither. Being a comment, I thought it would output whatever you typed in.

One to remember that.

I've made so many alterations thought it was somthing i did.

 

Thanks for having a look.

This was a problem I also had. It took me a year to figure out that for any comment to post it had to also contain a letter or other symbol other than a number.

I finally had our re-seller change my post to accept numbers only.

He had a reason why it was like that. I expessed my dis-pleasure so he fixed it for me.

By default, when a comment string contains only numbers and optionally the symbols ”.”, “+” or “-“ it is automatically converted from the text string into a numeric value and placed in the commvar$ variable. When this happens, the scomm$ string is cleared (which is why nothing is output as a comment). This allows the post writer to use the numeric value contained in commvar$ if so desired.

 

Prior to X, if you did not want a numeric value but rather a string containing numbers, you had to convert the value in commvar back into a string and then output it (and this had to happen in the pcomment0 postblock).

 

In X, we have added the ability to disable the commvar mechanism by initializing commvar$ to -1.

 

commvar$ : -1 #Disable automatic conversion of numeric comments

 

The v9.1 Post Processor Reference Guide has an example of the logic you can use to capture the value and convert it the old way (do a search for commvar in the 119 Comments.pdf file).
