    Machine PDM30 table nut stripped

    UPDATE--So, after close inspection, I discovered that the lead screw has a few long "scrape/gouge" marks along the threads. It appears this is what has caused the premature failure of the lead screw nut. I am assuming this took place during the manufacture/assembly process, however, any...
