Endless loops. Is it possible? [SOLVED]

Hello, I would like to repeat a loop for an unlimited number of times.
My first try has been

o101 while [1]
..
o101 endwhile

but LinuxCNC hangs while loading this code.

Next try:

o103 repeat [10000]
..
0103 endrepeat

thinking I could get away with an almost infinite loop. But loading times are very high.

It seems like it is trying to scan the program until its end, which of course is never reached.
I'm new to CNCs in general, so please forgive me if I'm missing something obvious.

This is on a BeagleBone board, bb-lcnc.blogspot.co.at/p/machinekit_16.html.

Thanks

Alberto

It seems like it is trying to scan the program until its end

Yes, to prepare the plot, check to see if the gcode program is within the working envelope of the machine, check for errors, etc.

Perhaps explain what you are try to do so a different approach my be suggested.

Hi

but LinuxCNC hangs while loading this code.

Linuxcnc does not hang, it is Axis that never gets to the end of its code preview.

You can use a different front end which just displays actual movements or disable the preview

linuxcnc.org/docs/html/gui/axis.html#_axis_preview_control

Thanks, I will try that.

I would like to use LinuxCNC like a sort of a PLC with a motion card.
I just need to wait for an input, execute some motions, then repeat.
Maybe some other project would be better suited for this task, like having a programming language with more features.

ArcEye was right. (AXIS,stop) did the trick.
Now I'll read about the PLC part. It would be very powerful.

Thank you very much.
