Retract at end of toolpath...

[kunfuzed]

At the end of each toolpath, I'd like a "G53 Z0", but at the end of the program, I'd like it to be "G53 Y0 Z0".

 

I added the "G53 Z0" to the pretract$, and the "G53 Y0 Z0" to the peof$, but at the end of the program I now have a redundancy I'd like to get rid of..

 

(last toolpath)

(last toolpath)

(last toolpath)

G0 Z5.

M9

G0 G53 Z0<------- Would like removed

G0 G53 Y0 Z0

M30

%

 

How can I describe "If last toolpath, don't output this"?

 

Thanks!

In the pretract section

 

 

if nextop$ = 1003,

[

pbld, n$, sg00, "G53", "Y0", "Z0." e$

]

else,

[

pbld, n$, sg00, "G53", "Z0." e$

]

Define a new variable...(last one in the list for this example)

 

#Misc variables

lim_flg    : 0      #Flag to only output limit warning once
tilt_flg   : 0      #Flag to only output tilt limit warning once
hst_flg    : 0      #Flag to output HST comments
kunfused   : 0      #

 

 

Add the first line here in the peof postblock

 

peof$            #End of file for non-zero tool  
     kunfused = 1 		
     pretract
     if lock_codes = one & rot_on_x, pbld, n$, *sunlock, sunlockcomm, e$
     rotretflg = 1

 

 

Then use that as your "condition" for your new conditional statement inside your pretract postblock.... you will have to put it in as something like this

 

if kunfused = 1, 
[
pbld, n$, desired retract code for the end of file, e$
]
else, 
[
put normal (not eof) code here
       ]

Thanks Jon, I'll give that a shot! What does 1003 represent, btw?

John,

 

Would it be better to

 

In the pretract section

 

 

if nextop$ = 1000 | 1001 | 1002,

[

pbld, n$, sg00, "G53", "Z0." e$

]

 

then in the

 

peof$

 

pbld, n$, sg00, "G53", "Y0", "Z0." e$

 

kunfuzed,

 

1003 is the g code in the NCI file that tells the post you are at the end of the file.

 

1000, 1001, and 1002 tell the post toolchange whether it is a new change or null.

as 1003 is only at the end of the file and that's where he needs the difference to show, that to me makes the most sense.

 

It surely isn't the only way to do it.

[JerryBenoit]

John,

 

Yes you are right that does make the most logical sence. Look for one condition verses three, therefore, you would not need the statement in the peof$.

Easiest to do:

 

pbld, n$, sg00, "G53", [if nextop$ = 1003,"Y0"], "Z0." e$

 

in pretract and nothing in peof$. We call that an "inline boolean".

 

You will see other examples of that type of thing in other output lines in modern posts (ie posts developed after X was released).

 

I should likely also point out that getnextop$ must be initialized to 1 in your post for the logic to work (should already be in your post but add it if it is not).

 

getnextop$ : 1 #Build the next variable table

Have used the inline boolean on other things, but you're right Paul, does fit very nicely here

[kunfuzed]

Thanks again guys!!!

End of file.

We call that an "inline boolean".

 

Pffft, show off...

 

Thanks for sharing Paul!

Thanks I needed a good laugh.
