Thanks Chip and Graham.
That has answered my problem.
Now to the mill.

Cheers

Thanks Graham,
I get the same display as you.
The problem is that when I simulate the cut with 'cycle start' the indicated cut for the rectangular frame follows the frame outline; but the indicated cut on the lettering does not. The top line of text for instance is shown as being cut at the bottom of the frame i.e. all text is displace downwards!.  This is just being done on the study PC, I have not tried it on the mill but I am assuming it will cut in error as well.

Any ideas

HI Team,
I have looked at the problem again and realized that G52 retains information and therefore putting G52 X0 Y0 near the start of the program made the part display correctly all the time, not just on the first occassion.
However I cannot get the view window to display the cutting path correctly so sending a copy of the code. Hope the file is not too big; generating test takes a lot of code, thank goodness for 'Write'.

I am programming a small frame which contains 3 lines of text. The lines of text and the frame are arranged as 4 subroutines called from the main program. Each line of text has been run as an independant program and works OK.
When 'assembled' and using G52 to locate each line of text within the frame I have a problem.
When the program is loaded to a newly started-up Mach3 the text is correctly positioned in the frame but when I engrave it on the screen it 'cuts' at a completely different place, not on top of the displayed text.
Subsequently, after a toolpath regen the text is out of position but engraving is cut on top of the displayed text.
I have played with the coding and cannot improve the situation!!

Is this a known problem or is it likely to be my coding? I have not tried cutting this on the workshop mill yet.

It is in the manual. Read more carefully next time.

Graham, You are a genius.

I dont recall seeing the info about the line numbers in the manual;and I always use them which explains everything.
Now I can stop banging my head against the wall.

thanks

Graham,
I typed your code into 'Notepad' and loaded it into Mach3.
I have tried your code, ie simulated in Mach3, and of cause it worked fine in single stepping and normal run mode though the graphics showed it cutting the same part twice despite the G52 shift of origin (expected).

I then typed in my code, very similar to yours, but it would not jump into the subroutine!.
Checked it in 'Word' and all carriage returns seemed OK.
Tried various changes to the code but without success so getting quite frustrated.

Will hopefully attache my code and I wonder if you could look at it and let me know what the problem is.

G-Code, CAD, and CAM discussions / Subroutine attempt

« on: May 28, 2008, 06:52:03 PM »

I am trying to use a subroutine to produce several copies of a part on a single piece of plate but with no obvious progress.
So far this is on the study PC not in the workshop.
Using the manual and answers on this type of problem given in the Forum I have written a program to cut two squares by calling a subroutine twice. If I run this program the sequence seems to jump the subroutine. If I single step through the program it still seems to skip the subroutine. If I start single stepping in the sub-routine it appears to execute correctly.

So my first question is - can such a program be single stepped through OK in Mach3 when correctly programmed?
I have also noticed that generally M98 & M99 are used but sometimes examples use G98 G99; are these typing errors?
Neither version helped me though.

See if you can get in touch with Graham Waterworth, he his very familiar with the machine.
