Post Question

Good Afternoon

 

I am using the MPMaster Post as a base. I have one problem. Sometimes I will forget to put a height offset number in a tool I create. It defaults to 0 in Mastercam. When I post it out it puts an H0 in my program. This causes my Haas to crash, obviously. I would like to change that so it will out put something that will make the machine alarm out, Possibly an HA or something.

 

Not sure where and how I need to do this in the post.

 

Thanks

Chris

Setting 15 on your Haas (on) will help with that.

Creating a tool library will help that also

It's easy enough to manipulate the height offset value. In mpmaster (which is what you said you are using), they use a common toolchange postblock. In it, look for this line:

code:

---

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

---

and add something like this above it:

code:

---

      if tlngno = 0, tlngno = 99999

---

That will work as long as your control chokes on it. On the other hand, you want to put in a test prior to that line something like:

code:

---

       if tlngno = 0, "M00", "(PROGRAM HALTED - NO TOOL HEIGHT OFFSET DEFINED - YOU ARE ABOUT TO BLOW UP OUR $250,000 MACHINE)", e

Chris,

You could add some logic in your post to say,

if tloffno=<0, then tloffno=toolno

This would have to be added in the psof and ptlchg postblocks.

Good tips Paul!

 

Thanks

I added this

code:

---

if tlngno =< 0, then tlngno = toolno, e

---

I get this error

 

code:

---

Argument expected.

Post line number 1209

Program execution halted due to error(s) in .pst

---

Ani Ideas?

[Paul Decelles]

Remove the "then" and the ", e"

code:

---

if tlngno <= 0, tlngno = toolno

---

We do not use "then" in MP and the "e" (end of block) is only used in output lines.

[MachineSMMC]

Got it!

 

Thanks
