Ok, then it seems not.
Machscreen seems to have no multiline control either.
Its working anyway so that's what counts.
One last point on this button, is it possible to code it as a "toggle" feature :-
Press once to park the gantry
Press again to return to X & Y zero positions.
Just wondering

I'm guessing it would need to toggle an LED on/off and check the state of that LED first?
