engraving subroutine

[kendo]

Is there a way to get access to the G47 engraving subroutine so I can customize it?

[kendo]

I'm engraving a part number in a window made of polycarb
this window has already been stamped with other text, and Im trying to match up as close as possible.
Im using a 30deg. sharp split point carbide engraver
cutting .001-.005" deep and it's leaving a bur behind which cleans up nicely if I make another, higher speed pass.
What Id like to do is have the subroutine trace backwards through each letter segment before retracting, this would be the fastest way to make two passes.

Kendo,
there was a free shareware program years ago that gave you G-code for almost every font and size there was. I have it on a disk somewere but i have no clue as to were.
maybe someone on here wll know about it.

it basically gave you the XY and Z corrdinates and you pasted it in your program, it also did mirror images and gave you the option of which way you wanted to start the lines.

I got it in 2000 or 2001. its on a back up, if you need it I will search for it as I have use for it as well.

Thanks Delw,

I think you might be talking about "DeskEngrave"
I got that a while back and I use it to engrave on our old tree machine
It doesn't have a nice canned cycle like the haas

I had already started on a job of over 500 pieces when I decided to try and get the haas to backtrace the letters.
I didn't get any response over the weekend so I copied the code out of the control manually line by line while single stepping through my program. (what a pain)
I eventually got it to work and it saved me some time sunday plus made the letters look a lot better.

If I engraved the letters normally, then ran through and made a second normal pass it doubled my cycle time
By backtracing each letter without retracting and starting at the beginning, the cycle time only increased 50%

The one thing about DeskEngrave is, it doesnt output arc moves.
That means it would have taken about ten times as long to reverse the code for each letter

I'd still like to get access to the G47 haas code. If I could, I'd try to add a variable to the macro call that told it wether to backtrace or not

I think thats the program kendo

Look on the disk (or USB Thumb Drive) that shipped with your machine for program 9876. However, if you don't have the macro programming option, you probably won't be able to re-load the program onto your control. If "enable macros" has a 0T next to in in parameters, you'll be able to set it to a 1T (trial) to load the program, then turn it off again so you don't use up the entire 200 hour trial.

O09876 isn't on the usb stick that came with the machine

Maybe someone with an older machine can look and post it up for you.
