  • Y axis drive motor / screw linkage slipping

    The setscrew holding the Y axis drive motor coupling to the lead screw keeps loosening. I'm going to get some Locktite - anybody got any better thoughts. It's a real pain to get to and I'd sooner fix this permanently (unless I need to change a motor someday). Thanks, H

    I removed the motor and used Loctite blue (#272) on the coupling setscrews. The setscrew that was coming loose did not appear to have any Loctite, or similiar, material on it. Hopefully, this is a permanent fix to the problem. Symptoms of slippage were sudden deviations from the expected path when changing direction.
