    Z axis travel is about 130mm. I can adjust the clearance by sliding the assembly up or down the gantry uprights (the benefits of extrusion). Ive built it so I can either use a belt as you suggest or slave it without any new modification. I think your right about using the belt. Only issue is I've only got 4.6 Nm Nema 34's. I could give it a try and see if one can move the gantry ok. If not Id have to splash out on a bigger stepper motor and then id have 2 spare motors.
