My prusa pi3 pro c dual extruder will not home x axis. When I run the M119 code all endstops works except the x axis. It stays triggered no matter if its unplugged. All other triggers work, i tried to invert endstop code from false to true, which makes x trigger open but when pressed it still reads the same.

I changed switch with others and new one, including wire.
I've check board for cross solder point and there all good.
I have another printer that is the exactly the same and swapped board but the same issues.

When I home x axis, extruder moves a nudge to the left but stops. The other axis home just fine. I believe the x axis stops after the nudge because the endstop is always triggered, falsely thinking its home.

I've yet to run plastic thru the extruder, but when I try to print, everything seem fine except it prints to far left.

Any ideas on how to solve this?

Hi,could you take some videos about it?It will be better to understand and get it solved.

The x axis and the extruder were operating in the wrong direction, so i turned the nema connector around to reverse polarity. I did the same to the extruder motor. When i try to hoe the x axis it move just a little to the left but it never homes or hits the endstop.
