Spindle speed question

[ckwhite]

Hey guys, I did a search and couldn't find anything. So here is my question.

 

I have setup my machine (fanuc 16i) to probe using custom drill cycles. Problem is the post always comes out with

"S0 M5"

And the machine doesn't like that. So I was wanting to put an if/then statement in the post that says

If speed = zero

then M5 (without S0)

 

Here is the section of the post that outputs the spindle speed

 

 

if n_tpln_mch > m_one, #Toolplane mapping mode

[

#Enter your mapping scheme here...

pg68_map

pbld, n$, "G43", *tlngno$, *zabs_s, e$

pbld, n$, *sg00, pwcs, "X0.", "Y0.", *zabs_s, e$

pcan1, pbld, n$, *sgcode, *xabs_s, *yabs_s, *p_out, *s_out, strcantext, e$

]

else, #5 axis and regular mode ( n_tpln_mch = -2)

[

if cut_ra_head & use_g45, #Swap xout and yout based on offset axis

[

tloffno2 = tlngno$ + g45_of_add

pcan1, pbld, *speed, *spindle, pgear, strcantext, e$

n$, *sgcode, pwcs, *sgabsinc, *yout, *p_out, *s_out, e$

 

pbld, n$, "G45", *tloffno2, *xout, e$

]

else,

[

pcan1, pbld, *speed, *spindle, pgear, strcantext, e$

n$, *sgcode, pwcs, *sgabsinc, *xout, *yout, *p_out, *s_out, e$

#if *speed = zero

]

I moved the S0 M5 to a line by itself thinking that I could isolate it then maybe apply a if/then statement, but I may be on the wrong track..... Thanks

Do you keep your probe as the same tool number?

[ckwhite]

Is your probe in a common pot?

yes, pot 50

[K2csq7]

Toward the bottom of the quoted text above....

 

pcan1, pbld, *speed, *spindle, pgear, strcantext, e$

 

 

the asterisk means force output (ignore modality)

taking that out wont fix it for you since the speed is probably different than it was previously.

What you need is....

 

if speed = zero,

[

pcan1, pbld, *spindle, pgear, strcantext, e$

]

else,

[

pcan1, pbld, *speed, *spindle, pgear, strcantext, e$

]

 

 

 

edit, now that I see the tool is always # 50, you could replace "if speed = zero" with "if t$ = 50"

should work either way.

 

You may need to put this in at multiple locations in the post....

i.e. null toolchange, start of file, toolchange, toolchange common.....

Start with one place, then if you see the S being output, just use the debugger to find the next location that requires this change in the post.

[ckwhite]

That did it! I moved the "*speed, *spindle, pgear, strcantext, e$" line back to where it was originally and added what you said.

 

Here is the code for any future reference.

 

if n_tpln_mch > m_one, #Toolplane mapping mode

[

#Enter your mapping scheme here...

pg68_map

pbld, n$, "G43", *tlngno$, *zabs_s, e$

pbld, n$, *sg00, pwcs, "X0.", "Y0.", *zabs_s, e$

pcan1, pbld, n$, *sgcode, *xabs_s, *yabs_s, *p_out, *s_out, strcantext, e$

]

else, #5 axis and regular mode ( n_tpln_mch = -2)

[

if cut_ra_head & use_g45, #Swap xout and yout based on offset axis

[

tloffno2 = tlngno$ + g45_of_add

pcan1, pbld, *speed, *spindle, pgear, strcantext, e$

n$, *sgcode, pwcs, *sgabsinc, *yout, *p_out, *s_out, e$

 

pbld, n$, "G45", *tloffno2, *xout, e$

]

else,

[

if T$ = 50,

[

pcan1, pbld, n$, *sgcode, pwcs, *sgabsinc, *xout, *yout, *p_out, *s_out,

*spindle, pgear, strcantext, e$

]

else,

[

pcan1, pbld, n$, *sgcode, pwcs, *sgabsinc, *xout, *yout, *p_out, *s_out,

*speed, *spindle, pgear, strcantext, e$

]

 

but what does this mean?

if cut_ra_head & use_g45, #Swap xout and yout based on offset axis

should I put it there too?

 

I don't have any S0's when I post so is this line not being used?

[Tim Johnson]

If you probe in what I'm guessing G45, then yes you will need to.

 

else,
 [						 #<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
 if T$ = 50,
  [
  pcan1, pbld, n$, *sgcode, pwcs, *sgabsinc, *xout, *yout, *p_out, *s_out,
*spindle, pgear, strcantext, e$
  ]
else,
  [
  pcan1, pbld, n$, *sgcode, pwcs, *sgabsinc, *xout, *yout, *p_out, *s_out,
*speed, *spindle, pgear, strcantext, e$
  ]

 

You may or may not have an extra "[" in the noted line.

THANKS

G45 is an alternate method of tool length offset call out, used for aggregate heads.

Personally, I keep the G43 and swap the zout for xout or yout.

 

 

EX....

G00 G90 G54 Y0. S1500 M03

G43 H01 X1.5

G00 Z5.0

 

Glad you got it working.

[Tim Johnson]

Yeah, I assumed so but the "Swap xout and yout based on offset axis" had me confused.
