I can think of a number of ways to do it using a snippet of G-code in the files, I assume this isn't an option?

Can you use the halui.program.is-running pin? linuxcnc.org/docs/html/gui_halui.html#r1_2_15

i really wanted it to work so as i could get a signal on every " / O100 ENDREPEAT " line, then the program would simply stop at a specific count. ( i already have "net outa_bar <= halui.program.block-delete.on" hooked up to stop pgm when the barfeeder is out) it would be nice to be able to preset an amount of parts when i load up a 5.5mtr length of bar! anyway, i geuss i can use a m1xx code, just was looking to make it invisible to the programmer thats all.

is the repeat number available anywhere?

i also tried using "net line_number => motion.program-line", but it is erratic and jumps to "0" while changing tools. it also is wrong, as i would have to compare it to line 10, or wherever the repeat starts from.

You could set up a pyvcp preset counter and stop the program with halui after the specified number of parts have been reached perhaps using a M1xx to increment a part counter and do the compare to the preset counter.

I am fairly sure that it isn't. I suspect that EMC2 itself has no idea how many times it has been round the loop.

I wonder if a better idea would be a switch on the barfeeder hooked into a G-code digital input?

O100 DO
<stuff>
O100 WHILE [Barfeeder not empty]

Ok, im currently trying to get an M1xx code working. you see, i normally load 4.5metre bars into the machine and run off as many parts as needed, i have the "out of bar" switch connected up to
net outa_bar <= halui.program.block-delete.on
and
/ O100 ENDREPEAT
makes it stop in such a situation.
But !
i want to be able to set a value while the program is running, not have to rely on the
/ O100 REPEAT [12]
value, giving me the ability to have a visible display on how many parts to go, and even possibly work out how long.

p.s. having a lot of trouble trying to make an m1xx code work, it was much easier when they are hooked up to "actual" pins.

Would it help to use a DO / WHILE loop and an actual counting variable? You would need to link the variable to an analogue output and write to it each time round the loop if you wanted to display it in a PyVCP panel.

Perhaps we need to decide what you want to happen, then figure out how to make it happen? Currently I think that process is being reversed.

Could you create a small parts counter component with the needed pins and toggle one pin for each loop somehow to count the parts? I'm not at a computer with EMC so I can't test this idea. Just thinking out loud...

What troubles are you having with M1xx?
