R vs. IJK

[mechman]

I have an older machine with 9600 for drip feed... I was thinking of posting R instead of IJK to shorten up the code... I set the break arc to 180... Any problems associated with doing this... I already removed the line numbers and spaces...

[BernieT]

I recommend staying with IJK. You will get more accurate arcs. And sometimes less problems with the machine calculating the center of arc from R.

 

A search will get much discussion on this topic.

 

Good luck.

[DavidB]

Stay with I,J and K. Sounds like your drip feeding anyway so it wont make a differance.

 

If your trying to get the program into the machines control and then run the program and it wont fit, then its time to go DNC.

what all is required to adjust the post to post in IJK.. I see two lines one to output arcs with option of turning it off and another to output IJK.. is this all needs editing in post to achieve the ijk output without messing something else up ?? thanks,..

[Rick46]

thanks kannon.. my fault for not using search option..

[PeterM]

BTW an arc described with ijk can be done in one line.

[Rick46]

well just just tried adjusting the value to output ijk format .. no go... still outputing R values.. must be more than this simple change..

Hmmmmmmmmmmmm...

thats all I had to do to get the code to change.

[Kannon]

what does your "parc" say?

code:

---

parc2         #Arc output for R

if abs(sweep) <= 180 | arcoutput = one, result = nwadrs(srad, arcrad)

else, result = nwadrs(srminus, arcrad)

*arcrad

 

parc0 #Arc output for I, J, K

iout = i * x_mult

jout = j * y_mult

kout = k * z_mult

if plane = zero, *iout, *jout, kout

if plane = one, iout, *jout, *kout

if plane = two, *iout, jout, *kout

 

parc #Select the arc output

if arcoutput = zero, parc0

else, parc2

not a biggie I been using r values for years on this machine just curious as to what if any advantages it would have on my machine with the IJK values..

are ya giving up?

 

what does your "parc" read?

 

look at my previous post and see if its similiar.

[Mike@Apollo]

I belive there is also a setting within the machine def or control def to output ijk.

I'm not sure if the post will overide it or not.

[PeterM]

See Thad's sticky is perhaps applicable here. If this is an X2 problem go into the control definition and go to arcs, all of the variables are set there, if this is a v9 issue, post edits are in order.

[Kannon]

great..if its a X question Hardmill will boot me out of the thread again.

 

Wheres the "POST xxxxE" when ya need him?

[Rick46]

here is the code from my post.

 

 

parc #Select the arc output

if arcoutput$ = zero,

[

#Arc output for IJK

i$, j$, k$

]

else,

[

#Arc output for R

if abs sweep$<=180 | arcoutput$=one, result = nwadrs srad, arcrad$

else, result = nwadrs srminus, arcrad$

*arcrad$

]

[Kannon]

So if your ...

code:

---

arcoutput : 0   # 0 = IJK, 1 = R no sign, 2 = R signed neg. over 180   

---

is set to zero like above it should be giving you the i,j,k output in your post.

 

must be in a control definition with X

[Guest]

Ok, so that's code from an X post, go into your control def >> arc and make sure your "Arc center type" is set for

 

Delta start to center.

[Rick46]

ok im not seeing that option on the control definition page under arc.. arc center type .. not there..

 

 

edit... found it... will try it out tomorrow.. time to go home now..

 

thanks,,,

[Guest]

Right here

 

[Dan_AKA_ROY]

^ Go to Arcs in your CD. Look for "Arc Center Type". There are 3 options below it...

 

XY plane: (change from 'Radius' to 'Delta start to center')

 

XZ plane: (change from 'Radius' to 'Delta start to center')

 

YZ plane: (change from 'Radius' to 'Delta start to center')

 

EDIT: John posted a pic of it.

[Rick46]

ahh that fixed it. thanks guys gonna try this out today...

[Kannon]

your welcome!

[shazam/TPP]

John Paris, dumb question here, how did you get that screen shot of your machine definitions page? I've tried a print screen and other things just to have a hard copy of mine. thanks!

[Guest]

print screen >> right click on desktop >> new .bmp

 

right clikc on .bmp file edit, should bring up paint >> edit >> paste in the screen shot, voila
