hi
I'm new to uccnc and I would like to add a button that controls the cable relay on pin 9 port 3
my button is in place on a new page


my button has the ID 20100
the macro is called M20100.txt
and I have set in I/O TRIGGER pin 9 port 3 low 94
what to put in the macros?? I ordered a book on c# to learn it
thanks in advance
