I'm in no great hurry tbh. I've temp fitted the table with my 4ft screws and try are working flawlessly! And the beat thing about it..... That big ass gantry is running on 2 x nema 23's lol and I still can't stop the gantry!! So this will do me for just now. When you get some time let me know and we will talk.

In the meantime you were wanting to try the rotating nut on some R2020 correct?
