I think you are asking to have the selector switch to select the MPG
wheel between feed and spindle override.
PNCconf doesn't provide this option Though maybe I should add it.
It expects that there is separate MPGs (or switches) for each override.
That is a PNCconf limitation not linuxcnc's.
I think it would be fairly easy to change this behaviour while still using
PNCconf
hopefully your selection switches can not ever be set so there is an axis
and an override selected at the same time.
select external MPG jogging with shared MPG
select external feed override , use MPG
select external spindle override, use MPG
make two custom named inputs by typing their name in the combo box.
eg.
feed-or-enable
spindle-or-enable
These are physically connected to your selection switches.
in custom.hal add these commands:
delsig so-count
delsig fo-count
net feed-or-enable => halui.feed-override.count-enable
net spindle-or-enable => halui.spindle-override.count-enable
net joint-selected-count => halui.feed-override.counts
net joint-selected-count => halui.spindle-override.counts
and hopefully that should do it.
any problems post here again.
