I have a Monoprice MSP 3D printer with the ADVi3++ 4.0.6 firmware installed and functioning. I was changing the heated bed yesterday and after that operation the y X-Axis will not home, it only moves to the right. I used a multi-meter to confirm that the X-Axis home switch is functioning. I have disconnected and reconnected the 2-pin connecter, the ribbon connector on the extruder PCB, and the other end of the ribbon connecter at the main board.
Does anyone know what pin # on the ribbon cable is the X-Axis signal to the switch? If I knew that, I could probe that pin on the Main board.
Which input pin is the X-Axis home switch?
Is there a way to view the state of the X-Axis input with the ADVi3++ 4.0.6 firmware?
Thanks in advance.
