Welcome to LinuxCNC.org

any ideas on a pin i can link to to make a parts counter?
i cant find any linked to "m02"

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]
