Hi, Just a quick question. If I was to build a machine with 1500mm guide rails on X and the bearing blocks were 250mm apart (is that enough or should I spread them further) then the actual travel distance will be only 1250mm so should I order a ballscrew with an approximate length of 1300mm or would you have the ballscrew span the whole length of the MC? same goes for the Y gantry and Z too.

Cheers, Charlie
