    Default Bridgeport Interact 412 Upper Z Limit Switch

    I have an Interact 412 that is acting like the upper Z limit switch is stuck closed. I am not certain where the limit switch is located in order to check it out.
    Any help in pointing me to it would be appreciated.

    It's right below the light on the right side of the head.

    Thanks for the help. I removed the front cover to get a better look at that area behind the light. Is the switch the item pointed out by the yellow arrow, or is it located closer to the red arrow.

    This is a new install and it needs cleaned real bad, I am also open to suggestions on what will clean this thick oil off.

    Look under the light the switch is mounted on the head.Bridgeport Interact 412 Upper Z Limit Switch-z-limit-switch-jpg

    Put 2 fingers behind the limit switch and you will feel the 2 posts , push them in and let them come back out.
    You may have to lube them up a bit.

    Thanks for the help! It was hiding in plain sight I will clean it up and see if that helps.

    The switch contacts were sticky and after cleaning them up, all three plungers are operating smoothly but unfortunately I am still having the same issue. I wanted to include a screen shot here.

    The Z axis thinks it is at 16" but in reality it is physically closer to 5". Does this help shed any light on why I continue to get a Z axis over travel alarm? Do I possibly have some setting out of whack?

    Thanks
