Hi Meerkat,

Still need more info I'm afraid.!

First looks like you have 3 separate home switches has they each have there own input. You don't need to do this and can wire them in series and save 2 inputs if you like. Both ways work just the same has Mach by default only moves one axis at a time.

How have you got the switches connected NO (normally open) or NC (normally closed).?

Have you setup Inputs #1 #2 #3 further down the inputs screen with pins 10, 11, 12.? because The diagnostics show inputs 1, 2, 3, are lit up.?. . . Do they change state if you push switch and do any of the M1,M2,M3 Home leds light up.?

If the M1Home etc don't lite up then try disabling these inputs just in case they are conflicting with home switches.? They shouldn't make any difference when homing because when Mach is homing it ignores any other function the same pin is assigned to and just uses the pin signal for setting home position only but you never know stranger things have happened.!!

Looking at the pinout for the TB board then you have the correct pins assigned to home switches so they should lite the LED's in diagnostics when switched. If not and provided the wiring is correct then you either have the wrong pins on the board or faulty board.?
