Forcing origin output

[So not a Guru]

We have a drag knife that I modified an MPMaster post for. I've got it working well with one exception. The machine needs to read a "G0 X0.0000 Y0.0000" line near the start of the file. To get it working, I used a literal line, but, since MP doesn't see my literal line move, this causes my 1st move to be a feed, from X0 Y0, to the start of the tool path. 

Is there a way for me to call a move to the program origin?

INstead of a literal string try this instead

pbld, n$, sg00, xh$, yh$, e$

Have you tried tox$, toy$ and toz$?  They will give you the tool plane origin values.

in your case;

 n$, <your rapid var>, *tox$, *toy$, e$

If you want the WCS origin values use t_orgin_x$, t_orgin_y$, and t_orgin_z$.

This gets me 

G0 X-10. Y10.

In your machine def set it to 000

That worked, after I assigned them formats.

Thanks

In the Axis combination home position?

I still get the feed move though.

I think you are missing something else.  Can you post a zip to go with sample file?

I would set x$, y$ to some values, then output them, and then carry on.   But I think you might be missing the first rapid positioning move in psof$, which in the MP master would likely reside in ptlcgh_com.

That may be it. I'll check in the morning

Can you just use reference points?

Probably, I was going to try that earlier today, but I get pretty bull-headed when I think it can be done. I'm unwilling, yet, to admit defeat.

That was it, I was jumping to ptlchg$, before ptlchg_com, in my psof$ postblock. Everythings good now.

Thanks Nick!

Good deal, glad I could blindly point you in the right direction.
