Hi there,
Just received a new gten 1500mm 2010 ballscrew and i have fitted the supports, I have laid the supports on blocks either end on a flat work surface and turning by hand i can visibly see a bend 2/3rds of the way along that at worst sways the screw 1.78mm of center.
This isn't normal for these screws is it? The screw its replacing is a cheap chinese SFU 2005 and that's straight as a die besides sag.
Cheers Jon.
