So I am trying to fix a custom built 3D printer for my institute and am running into a problem I can't wrap my head around.
So the limit switches for Y-axis and Z-Axis work just fine, but the X-Axis does not.
All three switches are Makerbot (3-pin), and all three light up the LED when they get pressed. However the X-axis does not get recognized by Marlin. When I diagnose with
M119 command it does not show as triggered even though the LED is on. All the other ones do.
All three switches are connected to min (X-min, Y-min, and Z-min).
Could this be a firmware problem? Or perhaps my RAMPS 1.4 has burned out the X-axis signaling? (I doubt this because the LED on the switch still turns on).
Let me know if you need any more info to diagnose the problem.
P.S. I have also replaced the X-Axis limit switch with a brand new one and the same result happens: LED turns on upon activation but it doesn't get recognized by the machine.
