post outputing 4th axis rotion in g10 line

[Guest]

ok all you post guru's. I am creating a post for our new horizontal 4 axis machine. all is going well until I hit a wall trying to insert B values in my g10 lines.

am using a GOTO statement at beginning of .nc file to direct to the following code at end of program.

 

N9999(SET ZERO'S)

( OP1 BASE POSITION G54.1P1 )

G90G40G0

G10L20P1X0.Y0.Z0.(need B value here)

 

( OP1 POS 2)

G90G40G0

G10L20P2X0.Y0.Z0.(need b value here)

 

the above i was able to get directly out of my

post but cant figure out the B variable thing.

my post experience is try all and error.

 

thanks. Doug

Doug, What post did you start with?

I'm not sure what you're looking for. pcout/pfcout will output your "B" value. cabs is where the value is coming from.

[Roger Peterson]

Doug, most people just output a B0. on the G10 line. The gcode file would still contain the rotary movements. All of the rotary movements would be shifted by whatever the G10 line contained for a B value. Would this work for you?

Ok tried to simplify too much.

this is the real end of program that i need:

 

N9999(SET ZERO'S)

( OP1 BASE POSITION G54.1P1 )

G90G40G0

G10L20P1X0.Y0.Z0. (need B rot value here

 

( OP1 POS 2 )

G90G40G0

G65P9018J1J2(need B rot value here)

( OP1 POS 3 )

G65P9018J1J2(need B rot value here) etc. etc.

 

G0T01111

M30

%

 

program O9018 calculates zeros from center line

of rotation (set in common offset) using coords

picked up and set at g54.1 p1. this requires

only setting base position coords say at B0 then will calc. for all subsiquent rotations on that station. got every thing except the rot value coming from my current post.

am thinking that i need to set up variables and asign the cabs values to them? am working on this

but could use any help i could get..

 

cheers

Doug,

 

I agree with Roger (usually B0) but what I have done in my post is read a misc integer on mt first posted operatio which I set to the rotation I want in my G10.

 

I also have a post question that verrifys the B value it will post (so you have a chance to change it on the fly).

 

It helps me when we are doing de-bugging of our programs, that way it wont make out to the machine at B0 when the parts sitting at a different rotation.

 

Just a couple of ideas

Here's how I do something similar to what you want;

code:

---

protcabsmacro

rotcabs = cabs

if (sav_mi2 = 43 | sav_mi2 = 44) & workofs$ >= 0,

[

p_wcs = 900

n$, "G91 G00 X0 G54P", no_spc$, 91,no_spc$, 35, no_spc$, *p_wcs, no_spc$, "+",

no_spc$, *workofs$, no_spc$, 93, e$

]

else, n$, "G91 G00 X0 G54P", no_spc$, 91, no_spc$, 35, no_spc$, "900", no_spc$, 93, e$ #<<<<<<<<<<

n$, "G90 G00 B", no_spc$, *rotcabs, e$ #<<<<<<<<<

n$, "G201", "B", no_spc$, *rotcabs, e$ #<<<<<<<<<

pcan1, pbld, n$, *sgcode, *sgabsinc, pfxout, pfyout,

"(", no_spc$, pfcout, no_spc$, ")", pgear, pwcs2, strcantext, e$ #<<<<<<<<<<

 

{/CODE]

 

This is what I end up with;

G91 G00 X0 G54P[#900]

G90 G00 B315.

G201 B315.

G90 G00 X0 Y0 G59

---

[/indent]

The G201 is my G65 call for fixture coordinate rotation. You can just use "cabs" instead of "rotcabs" for what you want.

[Guest]

much thanks. think i got it (with a little help from my friends).

 

thanks again

Doug

Doug, there is a G10 post on the ftp site that will output the G10 list at the top of the file. That one is setup for verticals but I also have one specificly setup for Horizontals. The only differences are the post variable "vmc" is set to horizontal and a B0. is output on the G10 line.

well theres some proof that our administrator has wasted hours of my time, cant get to the ftp yes that is our fire wall that i am banging my head against.

 

payed by the hour, but consiencious of the big guys buck.
