    I am considering using a single motor, probably servo and two ballscrews/pulleys on the X (longer) axis. Before I go ahead, it has been mentioned on another thread that there is a preference for putting the pulleys at the back.

    Apologies if this has been discussed before, but assuming the pulleys and belt are covered from swarf, what other advantages are there in choosing front or rear placement?

    Also, how good and smooth is joint belt, (length to bespoke measure), I've only used closed ready-made lengths. So I guess it's a question of designing the positioning of pulleys and tensioning parameters around a given ready-made length that's close enough to your ideal, and then tension as necessary? Thanks
