Defining the end of the program

[So not a Guru]

I have a section in my post I created using mr4 to have the machine pull up & out of the way, so the operators can check that the 1st part is correct, before running our transform ops.

It works fine, except that it also outputs at the end of the program. I'm trying to figure out how to make it not do that. Is there a predefined variable that I can use to make something like this work?

pfirstarticle      if "this is the end of the program",      [       mr4$=0       ]       else,         n$, "G91 G28 Z0.", e$         n$, "G91 G28 C0. A0.", e$         n$, "G91 G28 X0.", e$         n$, "G91 X65.",e$         n$, "G90", pwcs, e$         n$, "M00", sopen_prn, "CHECK 1ST PART", sclose_prn, e$         mr4$=0     if tcp_enabled = 1,        [         penabletcp        ]

You need to put the same logic in the "M30" line of your post. Problem is you will need to store the mi4$ value as once it is used the value it forgotten, but you need to store a little differently since you may call it again in other operations.

There is no need for me to store the previous value of mr4, because the program will have ended.

The snippet I posted is my whole postblock. I call pfirstarticle in my pretract postblock. My M30 call is in the peof$ section:

peof$            #End of file for non-zero tool                 toolchng = one      !gcode$ #to see that this is the EOF in pretract      n$, "G5.1 Q0", e$      if tcp_enabled = 1,           [            pdisableTCP           ]      map_mode = zero      pretract      prefreturn      ##### Custom changes allowed below #####      comment$      n$, "M30", e$      "%", e$

I'm not clear on how I could make the logic work there.

Okay the logic you used in pretract to call pfirstarticle you use to end the process the way you want for you need. The idea is what you use for one is the same trigger for the other, but to create output you want for the process to not happen. You have created logic to get output you want so now use the same logic to not get output you want.

Ok, I got it. But now I see that this might be a better fit as a cantext setup.

 

Thanks Ron

Well, that idea is proving to be an even more difficult endeavor. I'm going to try and make my original idea work.

 

Is there some way that I can query the NCI file to check when the final MC operation has been called?

if nextop$ = 1003

 

That is the typical code to check for the end of the program. But you can only get that value at the "last tool change".

 

With your original code example above, you would need to "wrap" the 'else' condition with a pair of square brackets, since you want to output multiple lines of code, when the 'if' condition is false.

Awesome! This worked perfectly.

Thanks yet again Colin, you are one of this forums greatest resources.
