GET_EXTERNAL_FEED_OVERRIDE_ENABLE()
GET_EXTERNAL_SPINDLE_OVERRIDE_ENABLE()
Always return 1. I am afraid. Maybe because in saicanon.cc we have:
/* MGS - FIXME - These functions should not be stubbed out to return constants.
They should return variable values... */
int GET_EXTERNAL_FEED_OVERRIDE_ENABLE() {return 1;}
int GET_EXTERNAL_SPINDLE_OVERRIDE_ENABLE() {return 1;}
So this needs to be fixed first?

Oh yes you are correct that is correct way to do this.

You might be right.

I don't think so, because you don't want to disable or ignore pause.
I think you want to cause the pause to happen as soon as it's safe,
at the end of retraction. This might be a deep change,
unfortunately.

Setting M49 multiple times is not what I was worried about - it's
the undoing of the M49 at the end of G84 that worries me.
I think maybe like GET_EXTERNAL_FEED_OVERRIDE_ENABLE()? See
src/emc/task/emccanon.cc
You would want to save the existing setting before G84, then restore
it when done.
