I think I found my problem with my dro, i have a lot of back and forth movement in my crossfeed nut , like I can physically pull back the top slide forward and back. I can make the nut , I just can’t figure out what size it is ? It’s 8 tpi , it’s the diameter that’s crossing me up.

I’ve watched every video from that fine man, like I said , making the nut isn’t the problem, I can even make another cross feed screw , I’m just wondering if this is some non standard size

Your DRO shouldn't care about any backlash--it should be reading the actual movement of the crosslide
