How do I get the current x position to post with an R.

 

Thank you in advance for your help.

css_r is a user defined variable 9not in any of our default posts) so you will need to search YOUR post to see how css_r gets assigned it's value and trouble shoot the math and logic in there to figure out why it's zero and not what you expect (R7.6372).

[88Matt]

It is nowhere else. what is the best way to get the current xabs position to post out with an "R" instead of an "X"?

thanks

[Jim Evans from CNC Software]

There are a couple of ways to achieve this but it depends on what you want to happen from a modality standpoint. for the example above we can get it to output R7.6372 now the next line has the same X, does X need to come out again as X7.6372 or should there be no X.

 

Modality in tact (in the example above no X on the second line if the same as R) - If you want modality to stay in affect then learn to use the nwadrs function. This function allows you to change the address string so the new string address gets output when a variable is output. So you could actually use nwadrs to give say xabs a string of R and then after the output use nwadrs to change it back to X. By using the same output variable and just changing the string address modality stays in tact. This requires that you have string variables defined for both R and X and you use the nwadrs function before and after the output to change and reset respectively. there is much more to this because of accounting for Absolute and incremental that once again if this doesn't make much sense, let your reseller or someone with post experience make the changes.

 

Here is an example but I can't guarantee it will work in your post (The example below assumes strr and strx have been defined appropriately. Notice I removed the call to pfxout from the pcss postblock as well. The call to output was moved to the pcss_r postblock instead).

 

code:

---

pcss            #Output Constant surface speed

speed = g_speed

if css_actv$, pbld, n$, *sg9697, *speed, spindle_l, pfcss_r, !css_actv$ e$ #lmr pfxout is added just for reference

!speed

 

pfcss_r

#Based on ABS/INC output change the address of appropriate variable from X to R

if absinc$ = zero, result = nwadrs (strr, xabs) #Absolute output

else, result = nwadrs (strr, xinc) #incremental output

pfxout #Call to output X

result = nwadrs (strx, xabs) #reset back to X address

result = nwadrs (strx, xinc) #Reset back to X address

---

If you don't want to keep modality in tact, then you can just assign the current value into the css_r variable like so

 

code:

---

   css_r = xabs

---

Ofcourse the above won't work completely because you have to account for outputting in Absolute (xabs) or incremental mode (xinc). You would need to add more logic for the above to work correctly. Something like this (you would also need to remove pfxout from the pcss postblock otherwise you would get R7.6372 X7.6372 on the same line).

 

code:

---

  pfcss_r

if absinc$ = zero, css_r = xabs

else, css_r = xinc

*css_r

---

If none of this makes much sense, that should be a sign to contact your reseller for help so someone with post experience can make the change for you. If you don't understand the basic rules of posts you will just get deeper into trouble trying to make this modification. ALWAYS BACK UP YOUR POST BEFORE MAKING ANY MODIFICATIONS - yes I'm yelling.

Thx Jim. That makes perfect sense.

It has just been a couple of years since I have really had to do any post mods besides the basics.

 

Thanks again

[Jim Evans from CNC Software]

Glad it helps. Let me know how it goes.

[88Matt]

Thx Jim.

Works perfect.
