Haas G47 Engraving Macro

Originally posted in the macro fundementals thread, but getting no responses so thought that it may indeed be a Haas issue, rather than a macro issue. Have no idea, actually. Still, posting in case someone is aware of a work-around for using a variable in the specified text area of the Haas G47 macro.

Original post -

I'm not sure if this is a Haas issue specifically, or a macro issue...

Is it possible to use a variable's value for the text to be engraved while using Haas's G47 macro function**?

In other words, when using the P0 (value), or even the P1 (value), can one reference a variable?
In essence - P0(#505)

All manner of mayhem broke loose when I tried so I'm sure that I'm doing something wrong, but want to make sure that it is even possible.

Thank you.

** - G47 Text Engraving (Group 00)

* E - Plunge feed rate (units/min)
F - Engraving feedrate (units/min)
* I - Angle of rotation (-360. to +360.); default is 0
* J - Height of text in in/mm (minimum = 0.001 inch);
default is 1.0 inch
P - 0 for literal text engraving
- 1 for sequential serial number engraving
- 32-126 for ASCII characters
* R - Return plane
* X - X start of engraving
* Y - Y start of engraving
* Z - Depth of cut

*indicates optional

On follow up, I was able to accomplish my goal, but would still like to know if it is possible to call the contents of a variable instead of literally specifying the text to be machined/engraved.

Thanks.

Since G47 is a Haas specific function, your thought that it is a Haas issue is correct.

There are many engraving macros around for Fanuc where the number to be engraved can be stored in a variable.

Never tried this, and I don't have macros enabled, but since G47 reads what's inside the parentheses, could it be something like G47P1.....([#504]) ?

No, I tried that. It did not like that.

Yeah... I think I will do looking for one of those, anyway. Apparently, Haas is using some of the same variables that are being used for our probing macros and it is causing a lot of havoc one the G47 is run. I don't like it one bit, so it's time to get straight up Fanuc'd and toss the haasome interference.

Are you aware of any that let one set the text height? ( this may be normal and commonplace, as I am simply ignorant of what's out there, available freely )

Thanks.

Well, mine can at least set height.

How much G-code do you know? I can post mine if you wanna tinker with it to suit your needs. Isn't really rocket science, it's just tedious coding all the characters.

The engraving macro I have does let one scale the character height, but requires the control to have G51 scaling option. It was specific to some aerospace applications for transferring 8 or 9 digit forging S/N data to the part being machined. It would require some modification to make if more general purpose. It was written some 20 years ago so I don't recall all the details , but I think the default character height was .1". PM if you would like a copy to peruse.

... and mine creates the character grid coordinates by a loop, so not dependant on that, but on the other hand I cheated with G52.

Should rewrite that but hell it's working...
