Another Post Question

[g huns]

I am a new user to MC can someone give me a post for... Just kidding Anyhow, I want to make the first line of my program look like this-

 

G92 G70 X(start point)Y(start point)

 

Can one of yous point me in the right direction. I am using a modified YASNAC.PST for this. Thanks.

look for pheader in post, then add as shown.

 

pheader

"G92 G70 X(start point)Y(start point)",e

Thanks Travis. Now how do I make it post the actual coordinates of my start point instead of

(start point). I should've been more specific. BTW what does the ,e do?

[BernieT]

I'm doing some guessing now, so bear with me.

 

I think you want "G92 G70", xh, yh, e

 

Where xh and yh are the home positions you set on the Tool Parameter page. G92 is usually associated with Home position.

I would like the x and y values to be the point at which the program's the first linear move of leaves from. Like the start point of the first piece of geometry that I chain. Does that make any sense?

[Travis_Buchanan]

Not 100% sure about this but here goes.

 

I think to do something like that the post would have to read through a toolchange. pheader gets posted before the toolchange. I think you would have to preread the nci and reap your xy from 1st tool change and buffer that infro or subout and merge latter on.

 

Thought # 2. Fix a custom drill cycle and pick that point for the very 1st op.

 

,e = end of line carriage return

Just because you want this position output “as the first line of your program" does not mean you must output it in PHEADER. That is defiantly doing it the hard way! The first X,Y position in the program is easily available in PSOF.

If there you have information being output in PHEADER than needs to be output after this initial G92 G70 X(start point)Y(start point) block, just relocate the code in PHEADER into PSOF.

 

Add these diagnostics lines into PSOF and you'll see the (start) X,Y coordinates.

 

code:

---

 psof          #Start of file for non-zero tool number             

 

"*{psof}-> x = ", *x, e #<diagnostics>

"*{psof}-> y = ", *y, e #< diagnostics >

Thanks Roger, it has been a long time since I worked with post. I knew there had to be an easier way. Just trying to help.
