How to repeat a Mazak EIA/ISO prog??

[Fendertok]

Is there a way to repeat a program without making a sub prog?
Im using a barpuller and i want to repeat the a program 30 times, i have tried M98 L30 but it just repeats the program forever. This is what the end looks like:
................
G01 Z2.
M98 L3
G00 X200. Z200.
M5
M30
%

At the end of your prg. you have to setup a counter like this. There are many differnt ways to do this, this is just one example.

#529=30.(NUMBER OF PARTS TO BE MACHINED); You can put this at the front of the program so it is easier to change.
#530=1.;
#531=[#531+#530];
IF[#531EQ#529]GOTO900;
M99;
N900
#529=#0;
#530=#0;
#531=#0;
#3006=100(COUNT UP);
M30;


We also use a dedicated loop program like this

G28U0;
M98P304545;
M30;

It will run program #4545 30 times and then hit the M30 and reset.

Hi.

You can try M97 to call local Sub-Program.

O#### (Main Program)
...
M97 P1000 L3 (Call Local Sub-Program at line N1000 and repeat 3 times)
...
M30

N1000 (Local Sub-Program)
...
M99 (End of Sub-Program and return to Main-Program)

I forgot to say that its a T32-3 control with eia/iso option.
Do you think it will work with that?
What control do you use?

[ChattaMan]

O0001
#500=1
WHILE[#500LE30]DO1

...your prog
blah, blah
...blah

#500=#500+1
END1
M30

M97 won't work either... that's a Haas code.

You'll probably need a counter like above examples. You could also try this:

M98H????L30 (where H is the "N" number or sequence number to start from).
Using the M98 like this is similar to a Haas M97.

Tried like this but only got illegal format alarm.
Why wont this work and on a Mazak T32?
This is my current testprog:

What control does it have?
Did it alarm out as soon as you hit Cycle start or a couple of lines before the counter variables?

Have you used variables before in this control??

Its a Mazatrol T32-3 system with EIA/ISO option, i have never used variables in iso and im not sure how the T32 handles the variables, cant find anything about it in the books. I will get a alarm at the first line of variables, " illegal format " The program works fine up to the variables. Is variables the only way to make it count?

[theemudracer]

I dont know anything about the Mazatrol control. You might not have Macros enabled on that machine. You might need to go to the Mazatrol forum.

Try this to test macro option:

#500=10.

And see if it puts a "10" into #500 or gives you a format error. A T32 with macro options should handle variables like any other machine.
