Last tool call

[kccadcam]

Howdy Folks, it's been awhile.....

Makino A51nx with Postability Post processor.

We want to pre- call "T2" as the last tool (coolant ball for washdown)

Current end of program forcing T2 M806:

G49
G91 G30 X0.
G91 G28 Y0.
G90
T2 M06
M806 (COOLANT BALL)
T0 M06
T0
M99
%

How do I call Last tool?

I've tried :

 pbld, pn, *sgcode, [if gcode$ = 1, sgfeed], *sgabsinc, [if not(tiltplane), pwcs], pfxout, pfyout, pspindleout,
            [if gcode$ = 1, *feed], scoolant, pcan3, strcantext, pe
          
       
        if next_tool$ = first_tool$, "T2" <-------------ADDED THIS LINE
        else,
        next_tool$, pe
        
          pbld, pn, pdyndatum, pe
          pbld, pn, ptlen, pfzout, pe
          if machsimflg,

But if you use the first tool more than once, it pre-calls T2 each time.

I'm sure it's simple logic but it's stumping me.... I've been out of posts for awhile..

M806 (COOLANT BALL)

How about using a Manual Entry for the coolant ball and then just let the tool staging do its thing.

Set up the coolant ball as a text string in a file and you can call it whenever you want.

That way if for whatever reason you don't want the coolant ball you just don't call the manual entry.

If you build logic for this output you will also need logic to by pass it if you need to.

It would pre-call the first tool, and then have to go stage T2 at the end of program.

Basically, 2 tool changes. This takes time.

Assuming there is a peof section, try adding it in there...

This way it is only called at the very end of the program...

If you use Manual Entry for the coolant ball it bypasses the tichg postblocks so should then stage first tool after manual entry has posted, or maybe I'm missing something?

I'm thinking something like the lines below instead of the line you had.  At he beginning of the post set test to 0.

if test = 0 & next_tool$ = first_tool$, "T2"
test = 1

At the last operation/tool in the program I don't want to stage the first tool, I want to stage T2 so that the tool is ready and waiting when M6 is called.

It will always be T2 as the last tool stage/pre-call.

IMO, as OLD_BEAR pointed out, peof is the place to go for this.  Just hard code it in the post if it's always there.

 ttblend$ seems like it was built for what you are trying to do.  It would allow you to stage tool 2 at the last tool change while your last operation was cutting.

It's boolean, so using it is pretty simple.

if ttblend$, "T2"

Thanks Jeff, works perfectly...

I knew it would be something simple...

if ttblend$, "T2" 
 else,
  next_tool$, pe
