How big can the G-Code be?

Coolant on/off is handled by emcio and runs in user-space. To guarantee that your trigger pulses are synched to motion you probable want to use M62 / M63
www.linuxcnc.org/docs/html/gcode/m-code.html#sec:M62-M65
Coded as nested loops the code would be about 12 lines. It would actually take just as long to preview as your other code, though, so the Axis preview control comments would still be needed.
I can see advantages in logging the data on the CNC machine, including the possibility of ensuring synchronised sampling.

That's a rather eccentric approachI've created the g-code with labview as its a very simple one:
Why not code it as nested loops? That seems much easier.The code is built sequential and without any iterations as shown in the following lines.

It was as you all said. The preview was the cause of the crash.
After i switched it off with "(AXIS, stop)" it loaded the code without further problems and the code is running since yesterday evening without errors.

Next time i'll get deeper into gcode.Like this it took no time for me to hack it into labview as i'm accustomed to labview for years. I guess in labview i realized the nested loops that you meant.
I used 3 while loops with an iteration of an coordinate in each loop. I also included a small question-answer environment to create the g-code because like this its easy to be understood by other students in our lab that think gcode is a dresscode for illegal citizens
We used the two computers because we have the accuisition software set just for labview and labview for linux is a pain to be set up. I've tried it, it works, but sometimes the chinese signs still appear so i start to get superstitious sometimes... just sometimes.
@Chris
Ty that was neat and easy. Just a few seconds of typing saved my setup of 3 weeks work.
@ Norbert
Exactly. it still takes a long time to load, but it loads now i've switched off the preview. I'll start working with nested loops now.
