I'm finishing up the mechanical portion of a new 1000mm x 1000mm machine and have some concerns about screw deflection (whip). In Mark's video he advises a slight compression preload on the screw, but I've read that this can make screw whip worse. I have ample room on this machine to sacrifice a couple of inches, so I was curious if there would be any advantage to putting a slight tensile load on the screw? My thought is to cut a couple of inches off of the C-beam to allow access to the extra length of the screw out the end plate that doesn't have the motor mounted to it, then once the bearings are well seated in the plates to put a brass Acme nut on the screw outside the plate and tighten it down before tightening the lock collar. Can anyone with more mechanical knowledge than I tell me if this would have any effect on keeping the screw in line?
