WCS

[Jeff2005]

I have been having trouble again with the work coodinate system, for some reason it is posting out a g54.1 p12 and I don't know why. I have had this problem before and what I did last time to fix it, it's not working this time. Can someone please help me.

 

thanks,

Jeff

Does it always post out G54.1 P12 for every tool change? Or have you set a new wcs and it is outputting this instead of a given value that you want?

 

The first thought would be that it's hardcoded to G54.1 P12 if it's consistant. With the second, it's possible your G54 callout section is messed up and giving you the wrong numbers.

 

This is my PWCS setion from a lathe post, I think mills are the same. See if yours is similar or totally different.

code:

---

pwcs            #G54+ coordinate setting at toolchange

if home_type >= one,

[

sav_frc_wcs = force_wcs

if sub_level$, force_wcs = zero

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

[

if sub_level$, result = mprint(swrkserror)

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'm sure I have done something wrong I don't ususally change anything without knowing for sure what I did. It is possible I did it and didn't realize it. I will look at my post and see if I reconize any changes. I haven't been in the post file.

If you go into your planes dialog, where it says work offset, what value do you have listed there?

 

And what work offset are you trying to output?

[Jeff2005]

This is my post area:

 

pwcs #G54+ coordinate setting at toolchange

if wcstype = two | wcstype > three,

[

sav_frc_wcs = force_wcs

if sub_level$, force_wcs = zero

if sav_mi9 = 1, workofs$ = sav_workofs

if workofs$ < 0, workofs$ = 0

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$

]

John I think we have been over this before and you told me it needed to be -1 . Is this correct?

[Guest]

-1 will get you the next available offset what that may be.

 

If none are used you'll generally get a G54

 

you can hard set them

0 = G54

1 = G55

2 = G56

and so on.

 

Now if you double check in your view manager, check the plane you are programming on, if there is a work offset value set there it overrides the planes offset

[Jeff2005]

I don't use any of the other offsets in my program G54 is all we use unless the operator chooses to use anther offset number. Would you tell me how to hard set them so this doesn't happen again?

Thanks.

[Guest]

In your planes box, work offset set it to "0"

 

BTW, this really is only a fix, something, likely in your settings is causing the bad output, you really need to track that down.

 

But the setting will get you through for the moment.

[Jeff2005]

Ok that fixed one operation but it didn't fix the next operation it put a G59 and gave me an error before it finished posting.

[Guest]

use edit common parameters to set them all Jeff

are you transforming an operation and this is where you get the other offsets? make sure that in your transform op that the work offset box is unchecked and that your only changing the toolpath not the wcs. just a jab in the dark.

Talk to your reseller about changing your post. I had my 3 axis posts set up to output all G54 no matter what. Don't have to worry about any settings. My 5 axis post is set to output G55 always. These are the only work offset #'s we use so we have them hard wired into out posts. Works great, one less thing for the programer has to worry about.

 

 

Note: We don't do multiple set ups on 1 machine. If there is a multiple set up the operator takes care of it. We don't run production, it's all tooling (one off parts).

Jeff,

The control definition you submitted with the Z2g file you sent is the default control. Is this what you normally use with this machine? Drop me an e-mail containing your CNC machines directory and I'll have a look.

 

Thanks,
