Robo 3d printer I can't home the X axis

  • My Robo 3d won't home on the X axis. It moves the other way about .5mm.

    This usually infers that the x-axis limit switch is not working correctly. I saw in the video where you were tripping the the switch by hand and measuring with the multimeter, but there may be a loose connection somewhere at the switch or on the board. Another possibility is that the wiring is frayed, thereby making the signal intermittent. If nothing seems to work, go ahead and replace the switch with a newer component and see if this makes a difference.
