MPMaster and Misc.Integers

[Josh Kinney -Elite Engineering]

I'm using MPMaster and I can't get the Misc.Integers to come out at the right time. I have mi2$ setup for "Tool Breakage Detection" and I want it to output in pretract. This works fine as long as there is no tool change

 

Let's say I have 3 op's using the same tool number and I want to force a toolchange at Op3 and I also want to do tool breakage after Op3. The problem is Op2 and Op3 outputs the mi2$.

 

For the life of me I can't figure this out!

 

Thanks,

i have this in my post, at end of pretract and also ptlchg blocks

 

if mi7$ = 1,

[

pbld, n$, "G325H#148(TOOL BREAKAGE DETECTION,FORCED2)", e$

]

else,

[

if (tldia$ <= 5.9), "G325H#148 (TOOL BREAKAGE DETECTION)", e$

]

" ", e$

if (mi5$ = 1),

[

 

works well for my post!

You can use the ptoolend$ postblock;

 

ptoolend$        #End of tool path, before reading new tool data
     !speed, !spdir2
     if nextop$ = 1002,
       [
       if mi2$,  add your breakage code (or goto breakage code)
       ]

This works but if you force a tool change it outputs it on the previous op. Let's say I'm Milling with an end mill and then I want to force a tool change and drill with an endmill but initiate tool breakage afterwards. It outputs it at the retract of both ops. It works fine if you don't force the toolchange.

       [
       if mi2$,  add your breakage code (or goto breakage code)
       ]

 

I couldn't get this to work by itself.

 

I know what I'm doing is overkill but I try to make sure every scenario is covered....

 

Thanks guys,

Can you post what you put into ptoolend$?

[Paul Decelles]

Initialize a numeric variable, load it with the value from mi7$ in pmiscint$ and check that variable in pretract instead of mi7$. The problem you are seeing is that pretarct is called by ptlchg1002$ which means the mi7$ value is the value from the next operation when there is a tool change.

 

Alternately, you could update the previous value of mi7$ (using !mi7$) in pmiscint$ or at the end of psof$, ptlchg$ and ptlchg0$ and then check prv_mi7$ in pretract.

Thanks Paul!

 

I put the following at the end of ptoolend

 

!mi2$

 

Then put the following at the end of pretract and pretract0

 

if prv_mi2$ = 1, ptoolcheck

 

And finally I created a post block

 

ptoolcheck

       if mr2$ = 0,
       [
       pbld, n$, "G325 Q.005 (TOOL BREAKAGE DETECTION)", e$
       ]
       if mr2$ = 1,
       [
       pbld, n$, "G325 Q.005 N9999 (TOOL BREAKAGE DETECTION - ABORT)", e$
       ]
