Max Characters in NC Comment

[Jake L]

Is there any reason not to increase this value in the CD from 256 to 512, or even bigger? Will it slow down the software, or the posting? MC2023 TIA

No reason not to increase it. This controls the "Max String Length" that you can "pass in the NCI to the Post". It does not handle comment length processing. Considering the speed of modern computers, you shouldn't notice any affect on Posting.

Yes, increasing the comment size will increase the nci file,

this will depend on how often you output comments in your post,

once per operation, it will probably be okay, if its once per line you will find the size will be much larger

I would think that would be more of a controller limitation.

There is no reason to increase it unless you need too, in my opinion,

looking for trouble

I have seen posts that output one comment for each nci line, to pass extra parameters for some machines, this is actually good information for me

Thanks for the quick replies. 

I just realized this wasn't the setting I was looking for. Is there a way to increase the max number of characters allowed in the Comment section of a toolpath?

#define COMMENT_SIZE            120 //!< Comment size

TCHAR comment[COMMENT_SIZE];    //!< operation description

//from the sdk

 

AFAIK the comment is a fixed array of size 120 characters and there is no way to expand it,

usually i use manual entry for extra comments

Yes, on the machine side, each controller handles comment strings differently. Some will break a long comment into separate comment lines. Others will simply produce an error.

That is what I do and teach it to others.

Fixed mistake

Byte is correct, you can't increase the max "Operation Comment String Length". That is a fixed length.

I also use "Manual Entry" Toolpaths when needed to add significant comments. The max "Manual Entry" length is 750 characters, however you can simply add multiple back-to-back Manual Entry Ops if you need additional comments.

Thanks for all the information. Manual entry it is
