Happy Holidays to All,

My system consist of a CNC4PC C1 ISO board to a Hobby CNC driver board. I've set up and calibrated all Steppers and have manually run the system. Works great, so I wanted to set up my E-Stop and Homing switches. I set up the inputs with pin numbers and port #1 then checked the enable. I jumped the 5V and pin10 input on the C1 board and the LED on that board came on. I then went to the diagnostic screen in Mach 3 and noted that the LED was not on in that screen. To verify that it functioned, I changed the active low and the LED was on. Any help would be appreciated.
