    Renishaw MH20-i not lighting LED

    The Renishaw MH20i probe in my Mitutoyo Crysta CMM is not lighting the red LED when turned on. The probe isn't working. The power did go out a few days ago and the computer shut down. Any thoughts? Probe? cable? PC card?

    Help! How much axial force from the table can a Bridgeport spindle head take?

    You can blue up the teeth to check contact. Phosphor Bronze or Aluminum Bronze with a hardened steel worm works. Cast iron gear and soft steel for worm also work. Mobil 634 Synthetic works well for worm gears.
