  • $\begingroup$ Yeah pretty sure this has been asked before. Just be aware that overconstraint in the linear travel mechanism vs leadscrew bearing mountings, can produce extra side forces, which you would barely feel on the guide rail, but will definitely have an additional effect at the leadscrew nut. $\endgroup$
