help? (on post switch/boolean)

[kinglouie V]

I'm trying to force a "W0" to limit motion on quill and not column. right now I'm working on the move going "home". not working out so good.

I can get the normal "Z0" and I can get both "W0" and "Z0" but can't switch between the two like I want. see below if interested.

 

code:

---

N820 M5                                 ptlchg1002$ p__9:928 872.$

N830 G91 G28 Z0. M9 ptlchg1002$ p__9:928 872.$

N840 G28 Y0. ptlchg1002$ p__9:928 872.$

N850 M5 ptlchg1002$ p__25:1063 872.$

N860 G0 G90 G54 G49 G80 W0 M9 ptlchg1002$ p__25:1063 872.$

N870 G91 G28 X0. Y0. ptlchg1002$ p__25:1063 872.$

Lou,

are your "[" "]" the way you like them?

 

Jg

[kinglouie V]

ya know, I was thinkin' the same thing. I can alter (to some degree) how this comes out based on the direction of those brackets but I cant' get them just right. is there a general "rule of thumb" I can look up?

[JG]

lou,

look carefully at the braces, I'm counting 5 "[" and 4 "]"

Lou,

 

Try your changes in ptoolend;

code:

---

ptoolend$        #End of tool path, before reading new tool data

!speed, !spdir2

if nextop$ = 1002,

[

if mi4$ = 1,

[

pbld, n$, sccomp, *sm05, psub_end_mny, e$

pbld, n$, *sgcode,*sgabsinc, *g_wcs, "G49", "G80", "W0", "M9", e$

pbld, n$, "G91", *sg28ref, "X0.", "Y0.", e$

absinc$ = sav_absinc

coolant$ = sav_coolant

]

]

[kinglouie V]

yep, I see that. the one at the bottom by the op_id is throwing it off it seems. we'll see?

[New Job]

The brackets are definitely mismatched.

 

The brackets appear to be mismatched in the first 'else' statement.

Might try flipping the one '[' and adding one ']'

[New Job]

Also:

 

Should these lines be like this?:

 

if mi4$ = 1,

[ <<<<------Note bracket

[Tim Johnson]

The quill info will never be read the way it is written.

 

code:

---

        if gcode$ = 1002,

[

#Actual toolchange

pretract # <<<<<<<<the last line read in this postblock

]

If you are refering to "[ ]", every "[" needs a "]", also if you are not doing so Indent all of your "[" a few spaces, then when you close them, line it up vertically, it will make it much easier to follow, I have to do that plus add extra blank lines so all the "logic" looks kinda like a arrow pointing to the right, even then I usually end up with a headache and mumbling things to my self.

I use an editor that will automatically line up brackets, keeps me honest. I use Notepad++, freely downloadable, set to use the 'C' language.

[kinglouie V]

thanks for the suggestions guys. Tim are you saying the inserted motion should go 'before' the

pretract?

[Tim Johnson]

Yes, if you really want it in that post block add it after "#Actual toolchange" and before pretract. I personally like using ptoolend$ myself, there's less "clutter" up there.

[kinglouie V]

thx, I'll look into it now.

[kinglouie V]

it wants to install code after every pass in the ptoolend$.

 

I think I need a break

[Tim Johnson]

Did you use "if nextop$ = 1002"? If you copy from the previous posting if should work just fine. Here's how the post I copied from looks;

 

code:

---

ptoolend$        #End of tool path, before reading new tool data

!speed, !spdir2

if nextop$ = 1000, prvtpsub = virt_tlplnno

if mi8$ = 1, pbld, n$, "G69", e$

pbld, n$, sgplane, e$

if nextop$ = 1002,

[

prvtpsub = 0

plane$ = 0

psub_end_s$

subout$ = 0 #main NC program

procesreturn, e$

pcoolantoff

sav_mac_tloffno = 0

sav_mi6 = 0

]

---

[kinglouie V]

thx, for your patience. I see it now. I'm not getting it at every pass now but just where I want it now. I'm working on not letting the pretract post after it now.

 

thx again.

[Tim Johnson]

You can create your own pretract and configure it how you want;

code:

---

ptlchg1002$      #Call at actual toolchange, end last path here

if op_id$ <> last_op_id,

[

#if cuttype <> one, sav_rev = rev #Axis Sub does not update to rev # CNC Mpfan V9.1

sav_rev = rev #Axis Sub does not update to rev

if one_rev = one | workofs$ <> prv_workofs$, sav_rev = 0

]

pspindle

whatline$ = four #Required for vector toolpaths

if gcode$ = 1000,

[

#Null toolchange

]

else,

[

#Toolchange and Start of file

if gcode$ = 1002,

[

#Actual toolchange

if mi4$ = 1, p_mi4_pretract #<<<<<<<<<<<<<

else, pretract #<<<<<<<<<<<<<<<<<<<<<<<

]

if stagetool = one, prv_next_tool$ = m_one

prv_xia = vequ(xh$)

prv_feed = c9k

]

ha! now that's a little gold nugget!

where sir did you pick that up??

[Guest]

All he did Lou was create a seperate post block, thus the p prefix

 

Then he used mi4 to check for it.

 

You can create and use post blocks for a myriad of tasks

[kinglouie V]

never seen it before.

[Guest]

Kewl stuff for sure

 

One of the reasons that I think MC posts just blow away the NX stuff that I have done.

 

If you can think it you can likely, fairly easily, sometimes, code and customize it.

[Tim Johnson]

Yeah, what I meant was to copy pretract, paste it and rename it to whatever you want. (I just made that postblock name up) Then weed out the stuff you don't need and add the stuff you want.

[kinglouie V]

I getcha'
