Add G08 to Post

[connormac]

I need to add " G08 P1 " before comp is turned on and " G08 P0 " after comp is turned off. If you need I can show ya'll all the stuff about comp in my post.

 

Thanks for all your help

Waoh....a fellow Texan Howdy

 

Srry I dont know how to do that. I never use CC.

 

But sounds like if you found in your post where it was turning CC on and off, you could just hardcode that in.

 

Your post should be outputting something when it does CC, yes?

 

Have you tried getting your reseller to help you?

Mine always helps me out when I can't figure it out.

+1 on the hardcoding murlin

Thats what I have done in the past.

For a fanuc 16i (g05), worked fine.

I have a post that was written for 6 different machines. I need it to post it on only 1 of the machines. The older fanuc and okuma's don't need them.

Connormac James will tell you there is a way to do this with misc or reals I do not know personally how to do it. I will suggest this that you take the post save it and the TXT files as a new name. Then play with the code the way you like and then go from there. It would probaly be good if I understand you correct that you dont use G41 or G42 you use the G8 P1 then just change the defintion to such in the post.

code:

---

 scc0    G40     #Cancel cutter compensation

scc1 G41 #Cutter compensation left

scc2 G42 #Cutter compensation right

---

You would want to look like this

code:

---

scc0    G08 P0  #Cancel cutter compensation

scc1 G08 P1 #Cutter compensation left

scc2 G08 P1 #Cutter compensation right

---

I dont know if this is what you are looking for which I think you aren't. Then I suggest you call your dealer cause I think what you are after is envloved.

 

Good Luck

You are crazy!!

Take back that profile and the senior title.

Time on the board means nothing w/ all the

help you've givin' here. Don't listen to any

rants. In my book you've earned it.

Sorry for interupting, and thank you for allowing me to hi-jack this thread.

 

PEACE

Have your reseller contact me and I'll give them a post that has all the Contour Control functions built in.

It's a bit ore complicated than "do this and do that", because there are some circumstances where you do not want to have it on so a switch is best.

[Greg Williams]

Hi,

 

I have set this function in the misc parameters page, It is a little more complicated than just adding it to the cutter comp settings. In most machines the risc processor needs to be turned off for any A or B axis rotations, Cutter compensation applications and a few other little things.

[Ron Branch @ 5th Axis]

As Always James has put you on the right path. I have only done things I need to make post I need work I have only need posts for 3 different machines to James is the Man when it comes to post around here.

Probaly not good advice on the problem you have here but will leave it up for other people to may have a different idea on soemthing to try.

[foolsh]

i thought G08P1 is to turn on the buffer memory and G08P0 to turn it off?

[Guest CNC Apps Guy 1]

In Fanuc controls, G8P1 is "Look Ahead" on and G8P0 is "Look Ahead" off. It is the most base form of contour control options. AICC/SHPCC, HPCC, and NURBS are "Higher" contour control functions. The higher versions give you more control over servo Acc/Dec in a nutshell, giving you more power over surface machining precision.

 

Just have your reseller contact me and I'll hook you up at no charge of course.

Take James up on his offer you will

be much farther ahead with a proven post.

Turning look ahead off at the wrong time

can reek havoc on a machine.

[Travis_Buchanan]

James is right. G08 on or off also reacts different with different cutting modes. G61,G62 & G64. I am right now trying to come to an understanding of what cutting mode and on or off with the look ahead. Trial and error on my part. God I love Fanuc manuals.
