A solution for using three 8mm lead screws on your bot using only one nema motor. Making your bed more solid and get rid of the sag. Im also using 40 teeth pulley on rods and 20 teeth on motor to get 2:1 ratio. Doubles the steps_per_mm

GT2 belt loop 6mm wide and 1524mm long. If having problem different tension between rods add another pin made of M5x25mm screw with 2 flange ball bearings. Im using 5x13x4mm Mini F695ZZ bearings.
