    I have my indexer running along the X axis. I used the "move tiny bits and examine" approach to get close then tested by balancing a small rule and dropping the Z down to make sure it remained flat...

    loose sensor

    I just noticed what looks like an X axis sensor is loose on my machine. I'm not sure where it's supposed to attach, but I'm guessing it's not supposed to be just hanging on the wire!
