My X axis limit switch is stuck on, so that in calibration homing the robot immediately registers the X axis as homed and moves onto the Y axis, but fails to hit the Y axis limit stopper and drives against the back of the robot.
How do I fix or replace the x axis limit switch? It definitely seems bent.
All fixed, to replace it I just had to unplug the red+black leads and unscrew the two hex bolts with an allen wrench. Then, I replaced the broken switch with a working switch taken off an OT-2 that was not being used. The switch is actually an OEM part, D3M-01K1-3 manufactured by Omron. You can buy them here.
The screws had some threadlock material on them which I dissolved in chloroform to make them easier to screw back in.
