Imput problem

[Troncatore]

Hello to ALL
... I have a Mill type Bf20 home made CNC ...and all was working well until two days ago..the X homing suddelly stopped to work ! I cheked:

1. limit switch=all ok
2. sensor= all ok
3. cable= all ok
4. cable continuity by analogic tester= all ok

The breakboard works fine, I used a new sensor for testing it, but the signal in position 10 is not received by Mach3. Maybe is a print port defect?
Thanks for any help!!

hi Troncatore, did you solve the problem with your input signal?
I also I have the same problem, I get no signal input from limits and MP300-ubobIIdthc. not turn on LEDs on the diagnostic screen
