G54 Output Only

[Wanny]

Hi all

 

My boss has finally taken the plunge and we now have X4mu1 running on one of our computers (the other 1 stiil running X3mu1). After setting it all up I updated the posts and all but 1 are ok with no error messsages after a bit of tweeking here and there.

 

The 1 I'm having trouble with is a modified Generic Fanuc 4X mill. I want it to post out G54 at the beginning only and when I change to mill say the front to rotate the part which it does but not add a new wcs(G55). As I learnt from this forum if I put a 0 in my wcs manager it does what I require, but it would be better if it was fixed by a setting in the post.

 

In X3I had the following in the post which fixed it but in X4 creates quite a few log errors;

 

g_wcs = workof$ + 54 =====>g_wcs = 0 + 54

 

So I guess there must be something I could do in this section of the post to fix this.

 

pwcs #G54+ coordinate setting at toolchange

if mi1$ > one,

[

sav_frc_wcs = force_wcs

if sub_level$ > 0, force_wcs = zero

if workofs$ <> prv_workofs$ | (force_wcs & toolchng),

[

if workofs$ < 6,

[

g_wcs = workofs$ + 54

*g_wcs

]

else,

[

p_wcs = workofs$ - five

"G54.1", *p_wcs

]

]

force_wcs = sav_frc_wcs

!workofs$

]

 

I've searched the forum and there are a quite a few threads on this with most answers pointing towards mi9 which is not present in our post. Is ths something I could add to fix or is there a easier solution

 

Thanks for your help in advance

Change this:

code:

---

pwcs            #G54+ coordinate setting at toolchange

if mi1$ > one,

[

sav_frc_wcs = force_wcs

if sub_level$ > 0, force_wcs = zero

if workofs$ <> prv_workofs$ | (force_wcs & toolchng),

[

if workofs$ < 6,

[

g_wcs = workofs$ + 54

*g_wcs

]

else,

[

p_wcs = workofs$ - five

"G54.1", *p_wcs

]

]

force_wcs = sav_frc_wcs

!workofs$

]

---

to This:

 

code:

---

pwcs            #G54+ coordinate setting at toolchange

sav_frc_wcs = force_wcs

workofs$ = 54

if sub_level$ > 0, force_wcs = zero

if workofs$ <> prv_workofs$ | (force_wcs & toolchng),

[

g_wcs = workofs$

*g_wcs

]

force_wcs = sav_frc_wcs

!workofs$

---

That should work for you.

Thanks Ron

 

I'll try that in the morning

[Rob @ Target Machine]

You're on the right track. Use the mi9$ logic from the X4 Mpmaster post to lock on to G54.

 

If you need a little help with it just email me at [email protected]

 

Just kidding, use my profile email. I'll add it in for you and show you the changes I made for reference.

[Rob @ Target Machine]

CrazyMillman - You beat me to it.

 

 

Edit:

Hey, wait a minute. What if he wants G55 and up for other jobs.

[Ron Branch @ Verisurf]

He said he only wanted G54 so I gave him what he asked for.

 

If he wants other offsets then that is a different type of post mod.

[Wanny]

Thanks all

 

I did want G54 only as the machine that the post is for won't accept any other wcs as it stands. You have to pay extra to get all extra bits added on, bit of a rip off really.

 

So Ron's mod I think will do the trick, I will test it out today.

 

Thanks again

[Wanny]

Sorry it's me again!!

 

I haven't had alot of time today to mess with the settings as end of month means get everything out the door. but I did the change that Ron suggested and below is a sample program.

 

It didn't output G55,56 etc as requested but it also didn't output G54 on the first line of code. And when it rotated intead of a G0 I'm getting G1,G2 - G7 where the G55, 56 would of been.

 

Hope that makes sense

 

Any help would be appreciated

im new of this so this might be a dumb ? but why cant u up date the post from x3 if it was working right ? just a thought?

[Wanny]

I did update but it didn't like the expression I was using in the X3 post, i got a host of errors in the post log, but thanks anyway.

 

However I think I've sorted the problem but can't test until I'm back in tomorrow.

 

Thanks all again

If you go to the planes(WCS) page, check the box work offset and put a 0 in the box they should all change to G54.

Works on mine
