Trying to make this work- G code

[WOODKNACK]

Hey guys,
Maybe someone out here can figure this one out. I have a program that is suppose to move my x axis 4 inches one way and then back again 50 times! But I cant seem to get it to repeat? Anybody have any ideas?

F10
G20 G90
M98 P1234 Q50
o1234
G1 x4
G1 x0
m99

I don't understand g-code that well, but I'll tell you what I know!
Firstly, you cannot have 2 g's on the same line, so you will have to seperate G20 and G90.
Secondly, I have just looked through the turbocnc manual, and it does not mention M98 and M99. In the turbocnc example (sample.cnc) the writer uses M60 and M62 to call sub-routines, so maybe this should be used instead.
Like I said, I do not know g-code, I have only read the instructions!

the "O"1234 is for a seperate program.
Do this;

%
O1
F10.
G20 G90
M98 P1234 Q50
M30

O1234
G91
G1X4.
X-4.
M99 
%

Assuming you're on a Fanuc compatable, make it just like that. You don't have decimal points on your feeds and X moves either.

The G90 and G20 are ok on the same line, G20 is (likely, depending on the control,) Inch programming, the G90 is Aboslute.

:edit:
If you're typing this in at the controller, you'll need to remove the "%"'s, and seperate the program. Create a new program, using 1234 as the number, and put the "lower" code in that program.

Still cant get it to work. Stops at m30 code?

Rekd, when you say it's ok to have the two g's on the same line, are you talking about TurboCNC, or g-code in general? Also, I have re-read the instructions, and I have also noticed this:

************
Code letters:
************
Blah, blah....

D,L,H,Q Future Use
etc...

So does this mean that the Q values are not implemented yet?

You have to read the manual

There is no way we could possibly guess what gcodes and associated parameters will work unless you can quote the relevant pages from your manual. Computers are very unforgiving of syntax errors!

that's on a fanuc or most fanuc compatables.

Try replacing the "Q" with an "L" and see if that works.

What Rekd Said

[WOODKNACK]

nope! no go. like I said it doesnt seem to be on that line. its the M30 line that it stops at.

[Rekd]

:edit:
Keep in mind, you need two programs to do this. The first program, O1, calls the second program, O1234 via M98 P1234 L50 (The L50 repeats 50 times.)

The M30 is the end of all programs. The M99 is the end of sub program, with loopback to the calling program, O1 in this case. When it stops at the M30, has it gone thru the 2 X moves?
:/edit:

Do you have a sample program? Perhaps a sample with sub programs or sub routines?

No this is just something I found on the internet and was trying to get it going in turbocnc..

[balsaman]

stops and says what? Any error?
