Tool Staging

[kccadcam]

Playing with the new MPMasterX_beta,,,

 

I have stage tools on, no problem.

What I need is to have the last toolchange call T0

instead of first tool.

 

code:

---

 toolcount = toolcount + 1

prvtp = rbuf(3,toolcountp)

if toolcountn <= tooltotal, nexttool = rbuf(4,toolcountn)

else, nexttool = first_tool$

---

Something like:

if current tool = last_tool, next_tool = "T0"????

 

This is for clearing spindle in Makino A55e....

Kevin,

 

Why not just stick a T0 right before the M30 in the peof section.

 

 

Might be the simplest way to do it.

Already there, Want it to pretool T0 to save time.

(every second counts you know)

T0 comes from toolpot 312 in magazine.

(farthest from toolchanger)

Here's the problem as I see it.

 

Even if on your first tool change into the program you set say in the psof section.

 

start_tool = first_tool$

 

now you can run a check in the ptlchng section

 

if t$ = start_tool

next_tool$ = 0

 

The problem comes up what if you reuse the starting tool number, the next tool would then be T0.

 

That's why I suggested the T0 before the M30.

 

Of course someone is going to pop in here and say do it like this and I'm going to say duh.

 

Live and Learn.

Try this to see if it works out for you.

In ptlchg_com replace;

code:

---

      pbld, n$, "G43", *tlngno$, pfzout, scoolant, next_tool$, e$

---

with

code:

---

      if nexttool = first_tool$,

[

pbld, n$, "G43", *tlngno$, pfzout, scoolant, "T0", e$

]

else, pbld, n$, "G43", *tlngno$, pfzout, scoolant, next_tool$, e$

Thank You Tim!!

That's exactly what I needed.

(much easier than what i was trying.)

 

I'm sure I'll have more questions before this post is finished.......

[Tim Johnson]

Anytime,

 

I was just noticing you don't need the brackets though it doesn't hurt anything to have them in;

code:

---

     if nexttool = first_tool$, pbld, n$, "G43", *tlngno$, pfzout, scoolant, "T0", e$

else, pbld, n$, "G43", *tlngno$, pfzout, scoolant, next_tool$, e$

---

I was thinking of something else then realized that wasn't necessary, made the changes and forgot to remove them.

[kccadcam]

Found one problem......

If the last operation is a transform op,

(in this case it was rotate 180 from top plane)

it still calls the first tool....

 

Is there a setting somewhere I'm missing???

Thanks for this!! I was pulling my hair out trying to get tooltotal to work right!!!

[Werktuigbouwer]

Other option:

ttblend$ is a variable which indicates last tool call.

#prestage tool
          pbld, n$, "G43", *tlngno$, pfzout, scoolant, 
          if ttblend$, "T0", e$
	  else, *next_tool$, e$

[Josh Kinney -Elite Engineering]

Yup. ttblend$ was the answer. 

 

Thanks!
