Hey folks, I'm having a bit of an issue.  I'm finally setting up my BC head.  I know, it's only been years, but well, I've been out of the country and my jobs on the mill only needed to be 3 axis until now.  Anyway, I'm setting it up, and am having trouble setting the home switches for the B/C head.  I have the B home switch set to port 2, pin 2, and C home switch set to port 2, pin 3.  If I manually connect the 5 volt to pin 2, it shows flags of both B and C home in the Diagnostics tab.  If I connect 5 volt to pin 3, I don't get a flag.  Note, this is without any home switches actually connected to the pins.  I'm in troubleshoot mode.  If I choose other pins for B home, it still does the same when closing the circuit.  It always throws B and C, but never individually.  Is there a setting in Mach for this maybe?  I'm at my wits end!
