Hi Tero,
You are in a maze of twisty little passages, all alike.
SAI is the "stand-alone interpreter" which is mostly used by the
test suite - it's not used by a running linuxcnc at all. Some of
the things the test suite don't care about are not implemented,
including this -- just as some things aren't implemented for the
AXIS preview when it doesn't make any difference for preview (in
src/emc/rs274ngc/gcodemodule.cc you'll find another return 1 for
this function.)
The important definition for the motion controller is in
src/emc/task/emccanon.cc:
int GET_EXTERNAL_FEED_OVERRIDE_ENABLE()
{
return emcStatus->motion.traj.feed_override_enabled;
}
I think it's likely it does actually work, because I can see the
status buffer gets changed by doing this test:
Run sim/axis
Home all axes
Machine/Show LinuxCNC Status
scroll down to feed_override_enabled
MDI m48, m49
See that feed_override_enabled changes
What test are you doing that shows it not working?
Chris
