But that in turn would need to be able to read that file on a restart. And be able to set zero defaults IF that file doesn't exist.
Can LinuxCNC do that ?? So could a memory variable that does not get cleared by a re-run. Something that would be made known to LinuxCNC but is not zeroed or preset by making it visible. But, here is something else: If g52 or g92 and its ilk are not used in a program, is it safe to use a couple of those #numerical locations for storage? It rather sounds like they are free for other uses, but if not ever used, do they contain trash at powerup? In that event, one could write a program to clear them that is run by actually running it, or perhaps tying it to an mdi function. Or even by running g92.1 from the mdi screen, which I assume clears that whole block of #locations. So the only one that untouchable is #5210. I could then use 3 of the other locations for exactly what I want, they are already known to LinuxcNC but ignored if #5210 is cleared. Right/wrong? Persistence, even over a non-powerdown reboot, is quite important.
