I don't know about a post nci.

 

But I did try a few thing on the MC9 generic fanuc post

 

And I was able to get it to output this

Maybe someone else knows an easier way. But this is what worked for me in a couple test programs.

 

However i was not able to get this to work in a program that I used transform rotate toolpath.

 

 

Also, i only used whole numbers. I'm not sure how to go about doing it if you are rotating in less than 1 deg increments.

I just realised i didn't have it set up for any angle over 180

 

so I changed this

 

code:
pindex          #Index output

if index & rot_on_x,

[

if cabs <> prvcabs,

[

spaces = 0

 

if indx_out = 0, n, " ", sindx_mc, "0", e

 

if indx_out >= 300,

[

n, " ", sindx_mc, "3", e

indx_out = indx_out-300

if indx_out = 0, n, " ", sindx_mc, "0", e

]

 

if indx_out >= 200,

[

n, " ", sindx_mc, "2", e

indx_out = indx_out-200

if indx_out = 0, n, " ", sindx_mc, "0", e

]

 

if indx_out >= 100,

[

n, " ", sindx_mc, "1", e

indx_out = indx_out-100

if indx_out = 0, n, " ", sindx_mc, "0", e

]

in the post

 

and was able to get this nc output

 

code:
( DRILL AT 45 DEG )

N30 M84

N32 M85

N34 X0.

N36 G98 G81 Z.9 R1.1 F10.

N82 G80

N84 M5

N86 G91 G28 Z0.

also just so you are aware I have the post setup to always be positive between 0 and 360 deg

here

 

code:
pindxcalc       #Index move calculations, direction is shortest

#Check if in tolerance

cdelta = frac(abs(csav)/ctable)

if cdelta > ixtol & cdelta < 1-ixtol,

result = mprint(sindxerror)

cdelta = prvcabs - cabs

#Phase shift delta 10 revolutions, check odd/even

if frac(int((cdelta + 3600)/180)/two), indx_mc = one

else, indx_mc = zero

#Set range 0-360

indx_out = csav

while indx_out < 0, indx_out = indx_out + 360

while indx_out >= 360, indx_out = indx_out - 360

Not, a problem.

 

I'll be honest w/ you. I've never seen a rotary that requires code like that. I just thought it would be fun to try and figure out how to do it.

 

But I'm guessing yes, you will need code for each angle. ex. our rotary requires a G120 before each rotation. but almost all rotaries and indexers required something different.

 

Do you by any chance have a manual for the indexer you are using. That may have a better definition of exactly what is required at each rotation. Then if there is more, or less required than what you currently have we can probably find the answer.

I'll put the post on the FTP. Like I said it's just the generic fanuc. It's under the text_post_misc folder

 

Called it Heavy_post.zip

 

If you want, and it wouldn't get you in trouble you could send me the file (or upload it) you're working on and I'll run my test using it. There may be something I'm over looking.

Heavy,

I think I have fixed the output to be three places

 

Here are all of the changes I made

 

Replace the entire pindex section to this. It's cleaner i believe fixed our issues

code:
pindex          #Index output

spaces = 0

if index & rot_on_x & cabs <> prvcabs,

[

if indx_out < 100, n, " ", sindx_mc, "0", e

 

if indx_out < 10, n, " ", sindx_mc, "0", e

 

if indx_out >= 300,

[

n, " ", sindx_mc, "3", e

indx_out = indx_out-300

]

 

if indx_out >= 200,

[

n, " ", sindx_mc, "2", e

indx_out = indx_out-200

]

 

if indx_out >= 100,

[

n, " ", sindx_mc, "1", e

indx_out = indx_out-100

]

 

if indx_out >= 90 & indx_out < 100,

[

n, " ", sindx_mc, "9", e

indx_out = indx_out-90

]

 

if indx_out >= 80 & indx_out < 90,

[

n, " ", sindx_mc, "8", e

indx_out = indx_out-80

]

 

if indx_out >= 70 & indx_out < 80,

[

n, " ", sindx_mc, "7", e

indx_out = indx_out-70

]

 

if indx_out >= 60 & indx_out < 70,

[

n, " ", sindx_mc, "6", e

indx_out = indx_out-60

]

 

if indx_out >= 50 & indx_out < 60,

[

n, " ", sindx_mc, "5", e

indx_out = indx_out-50

]

 

if indx_out >= 40 & indx_out < 50,

[

n, " ", sindx_mc, "4", e

indx_out = indx_out-40

]

 

if indx_out >= 30 & indx_out < 40,

[

n, " ", sindx_mc, "3", e

indx_out = indx_out-30

]

 

if indx_out >= 20 & indx_out < 30,

[

n, " ", sindx_mc, "2", e

indx_out = indx_out-20

]

 

if indx_out >= 10 & indx_out < 20,

[

n, " ", sindx_mc, "1", e

indx_out = indx_out-10

]

 

if indx_out < 10, n, " ", sindx_mc, indx_out, e

 

]

 

 

spaces = 1

also change this

 

code:
fmt  A   4   indx_out    #Index position

to this

code:
fmt     16   indx_out    #Index position

These changes caused the post to put out the following nc code

 

code:
( DRILL AT 0 DEG )

N24 M80

N26 M80

N28 M80

N30 X0.

N32 G98 G81 Z.9 R1.1 F10.

( DRILL AT 3 DEG )

Maybe this coding is a little more compact. You can run this post with a dummy -.NCI file (any -.NCI file -- the -.NCI file is not read if the only prenamed postblock is the PQ postblock.

 

fastmode : yes

 

fs 6 1 0n

 

fmt 6 a1 # Hundreds digit

fmt 6 a2 # Tens digit

fmt 6 a3 # Units digit

# ^ When there is no prefix letter, the number will concatenate (no space)

 

spaces : 1

 

fq 1 a Input positive angle 0..360, neg. angle to exit

 

pq

q1 # Prompt to input test number

pdig

 

pdig # Find the separate digits in input value 'A'

a3 = frac(a/10) * 10 # Units digit

a1 = int(a/10)

if a1 = 0, pdig1 # Delete this line to output leading zeroes

a2 = frac(a1/10) * 10 # Tens digit

a1 = int(a1/10)

if a1 = 0, pdig2 # Delete this line to output leading zeroes

pdig3 # Hundreds digit

 

pdig3 # Output 3 digits

a1, e # ",e" produces a linfeed

pdig2

 

pdig2 # Output 2 digits

a2, e

pdig1

 

pdig1 # Output 1 digit

a3,e

ex

 

1999. Product major version number that post supports? 9

FS is the Format Statement. FS 6 means it's Format Statement number 6. It could be an;y number except 1 if it should concatenate with the CW/CCW variable (add on with no spaces). The FMT statement for the angle digit should then reference FS 6. The last two digits of the FS (1 0n) mean "output 1 digit before the decimal point and 0 digits after the decimal". The 'n' is important. It means non-modal, which means output the digit even if the digit was the same the last time it was output. The space between the 1 and 0 would be a "." if you wanted to output the decimal point.

The original angle is "a".

The purpose of a1, a2, and a3 are explained at the top of the post in 3 FMT statements. They are the hundreds digit, the tens digit, and the units digit of the 0..360 number being broken down. A1 is also used temporarily to store a partial breakdown number. There is no manual which will explain this, since these are user-named variables. I made up both their name and usage. INT and FRAC isolate the integer and fraction portion of a number. If you send me an e-mail I can send you the file.

I will definetly agree that Johns way was Nice and compact. I only know enough about post's to be dangerous.

 

I will have to learn more about the math involved w/ the Int and Frac values.

 

Mike thanks for the link.

 

and Heavy, Wasn't a problem. John ended up doing all the work for me I just had to get it into your post. I think my original way would have ended up working (once I got all the bugs worked out) But fortunately someone else saved the day.
