Hi,
your home inputs are wrong.
Looking at the last pic you posted you have all home input assigned to port 1 which is fine
but input pins 0 ,1, 2. There is no pin 0. Pins 1 and 2 are output pins.
On the page you may have noted that the input pins available are 10-13 and 15. Usually one input pin is assigned for an Estop, commonly one pin
for a series combination of limit switches. That leaves three inputs left. X home, Y home and Z home is a fair choice but you'll not have any inputs
left for a probe say.
In the first instance its probably a good idea to have one input for each limit switch. Suggest hook your X home switch to pin 11, Y home to pin 12
and Z home to pin 13. Once you have them hooked up manually flick each switch in turn while watching Machs diagnostic page, you should see
the LEDs corresponding to each switch operate.
