Need to add a sub every 1000 lines or so.

[Toymanf]

Hello all. I am running engraving/carving codes of up to 500,000 lines. I need suggestions on how to modify the code(output by photovcarve) to cycle a pair of solenoids periodicly to give a blast of air, then coolant.
I am not setup for flood cooling. The jobs take 3-12 hours to complete.
I am hoping there is a simple software solution that will add a block of code every "X" number of lines. It would be even better if I could add this block every "X" number of times that the Z reaches 0.060"

Any suggestions for how I might accomplish this would be greatly appreciated. I am by no means a programmer, but I am willing to try if pointed in the right direction.
Thank you
Frank

This should be able to be done with a 'MSWord' macro or a program called GWK.
Does the code you wish to add need a separate line or can it be added to the end of a existing line?
Also are the lines numbered?
Please post half a dozen lines of example code to examine.

This is the first few lines of the g-code.
I don't think it would cause a problem if it was tacked on to the end of the line. ie z0.060"relay on pause relay off(in proper syntax of course)

Can you also supply the code you wish to add.

[Kiwi]

I notice the code you supplied has no spaces at all in each line.
Will the machine run ok with a space before a axis character.
My thought is to run a Find and Replace 'Z' with ' Z' so the AWK macro will find the space if the code can be added onto the end of the line.

[Toymanf]

After playing with this for a while, I was able to set up a "brain" in mach 3 that effectively counts the number of times that the z reaches .060 then cycles the relays as needed.
Thank you for the input.
If my tests work out, I will share the info if wanted.

I would really like to see how you do this. I may never need it, but that kind of knowledge is worth having. Thanks.

[eauth]

you can do that quite easy with mawk.

BEGIN{
  FS="Z"
  count=0
}

# print original record
{ print }

# check records that start with N and end with a Z field.
/^N/ && NF==2{
  z=$2
  # count lines with z>=0.06
  if (z>=0.06){
        count++
  }
  # add lines every 10 times
  if (count>=10){
    count=0
    print "your line 1"
    print "and a second line"
  }
}

There was a thread about mawk if you want to know how to use mawk in windows.

Eauth... Thanks for your code.

I got some code to do what I required.

{
if ((x=index($2,"Z0.0600")) > 0) {
Appendix = "AirBlast";
}
print( $1,$2, Appendix);
Appendix = "";
}

On re-reading the original post, I see my program doesn't quite do what was asked.

Eauth...Does your program need a space before the 'Z' to create the second field in the GCode?
