Hi All,
I'm in the process of designing my first CNC router table. The design that I'm thinking of will require a gantry span of 5'. I figure that my light-weight gantry design will not be stiff enough to be driven by just a lead screw on one side. I thought of placing a crossbeam underneath the table connecting the two legs of the gantry. However, I've decided not to go in that direction. Instead, I'd like to have a lead screw on each leg. Has anyone driven a single axis using two lead screws before? If so, how did you drive the screws (two motors)?
Thanks,
