got some more feutering done on the x axis design this evening

firstly i modified the stepper/ballscrew mount by lowering the motor giving space for gib screw access holes and then added a rib on the back for some extra rigidity

then i drew a 1204 ballscrew and crude representations of thrust bearings for the ballscrew mount
a 450mm long screw leaves just over 38mm overhanging the table travel extremities

still have to decide on a pulley ratio so i can incorporate it into my design, any thoughts?


could the moderator please change the title of this thread to 'centec 2 ballscrews' as its getting far of the original topic and it would be a shame to have to start again
